"I recently attended PEAK training academy. Since graduation I have performed approximately 40 polygraphs. I have dealt with pre-employment applicants and criminal cases. So far, all areas of the training were extremely beneficial while being out in the field. I have utilized the tools that I have learned throughout my training, and it has been very beneficial for my polygraph exams. Not only have I been able to utilize the training from school, but being a PEAK alumni I am able to reach out to all other alumni including Ben Blalock for questions and/or clarification on a topic. So far, I have enjoyed the polygraph division within my organization and was able to jump right into my exams nearly seamlessly. The training was challenging, but enjoyable. Ben Blalock and his staff challenges you to maximize your thought process and the understanding of polygraph. Thanks for all the training."

PEAK Basic Course

"I attended PCSOT training in March 2023 and I highly recommend this training. Ben and his team of instructors take polygraph very seriously and learning from them was a great experience."

Todd Eby
PCSOT Course

"In March 2023 I attended PCSOT training at PEAK. The training was highly effective and comprehensive. The instructors at PEAK are knowledgeable, experienced, and passionate about the subject matter, and they provide a supportive learning environment for all attendees. If you are a polygraph examiner looking to improve your skills and knowledge, PEAK could be a valuable resource for you."

Marc Mitchell
PCSOT Course

"When the time came to evaluate a polygraph examiner training program, I had very high standards and expectations.

As a Military Intelligence Veteran and retired Secret Service Agent, I have been exposed to some of the highest caliber examiners and polygraph standards throughout my career.

To assist in this endeavor, I sought guidance from colleagues representing a variety of Federal, local and State law enforcement agencies. All are trusted, well respected current or former polygraph examiners with decades of experience. They all echoed what my research had revealed - PEAK is the gold standard when it comes to the highest caliber polygraph training.

As a private examiner, the sole financial responsibility for training was mine. Unfortunately, I did not have an agency to fund my training. With that being said, it was even that much more important to find a program that not only provided a robust and practical curriculum, but one where I knew I would get an excellent ROI.

PEAK did not disappoint and definitely delivered! Director Blalock, Sandy, Joe, Scott, Jim and the rest of the training cadre and lab assistants were extremely knowledgeable and eager to share their vast experience. Highly recommend for any private or law enforcement examiner looking for the best training available."

Michael Perl
Basic and PCSOT Courses

"I would highly recommend this course to anyone. I did Basic Polygraph Training here at PEAK and had no other choice to return for continuing education. The PCSOT Course was very informative, and I'm impressed with the quality of material presented. The instructors are very knowledgeable and experienced in the field. The course material presented was done in a clear manner. The course covered a wide range of topics related to polygraph testing of sex offenders. Overall, this course has provided me with a solid foundation to administer polygraph testing on sex offenders. PEAK today, tomorrow, and forever!!!!"

Nicolette Vassell
PCSOT Course

"I am a PEAK graduate from 2023-01, this is my first time going to a polygraph school. I can say many good things. They explain the material very well. In addition, we have the best instructors, they take their time to teach the material in detail. They are very thorough with all the material. I believe it was a lot of the material but at the end, everything came together, and it made sense. There are many materials to absorb, any student that graduates they have an ample knowledge of how to administer different exams. I liked it so much that I signed up for the PCSOT Course and it was excellent. I would highly recommend this course to anyone who might be interested in this course and has no knowledge about it. PEAK has the best instructors they can have from my point of view. I think it is an excellent school. There are a variety of individuals that come here from different parts of the world. Is interesting to see the students here from different types of backgrounds and cultures. I will be coming back here for the advanced course later on and every year. This is an outstanding school for anyone who wants to learn."

Yusnier Gutierrez
Basic and PCSOT Courses

"Anyone looking for their Basic Certification will thoroughly enjoy the experience at PEAK. Those more seasoned examiners in need of continuing education credits will be extremely satisfied. The level of instruction is unparalleled. The passion for best practices and science guided instruction is evident in everything they teach."

Michael Conkey

"PEAK is without a doubt the best training program if you want to be successful in your career! I completed the Basic Polygraph training program in July 2018 and completed my first round of PCSOT training the week after. I wanted to make sure I embarked in all PEAK had to offer while I was in town. I returned to my agency and completed a total makeover to the outdated practices and procedures. I learned so much material along with best practices and procedures that I was able to guide my agency. I'm now back in the lovely city of Cape Coral completing an overdue course refresher in PSCOT now that I'm about to start running PCSOT exams! THE Ben Blalock actually teaches and is very much hands on and available to all during the training! The staff is very knowledgeable and willing to help and go the extra mile to make sure you learn the most and get the bang for your buck. Sign up for PEAK training, YOU will have NO regrets!"

Jennifer Plymouth
Basic and PCSOT Courses

"My experience at PEAK was a great one, having completed my basic polygraph training at another institution. The materials presented was unmatched and in keeping with APA guidelines, which will have a great impact on my career. The level of encouragement for continuing education was well received. I would recommend PEAK to other agencies in Jamaica and encourage the JCF to continue its partnership with PEAK."

Carol Grant

"I attended the Basic Training Course followed by the PCSOT Course. The basic course was very challenging, but after completing the course, I have the confidence and tools needed to be successful in this field. I highly recommend PEAK to anyone looking to get into the polygraph field and to those looking for continued education."

Michael Bartak
Basic and PCSOT Courses

"I attended PEAK Credibility Assessment Training Center's Basic Polygraph Certification Course in 2022. The course was challenging and required a high level of commitment to the class and learning the material. The majority of days the class would start out with a question and answer session regarding previously learned material and general polygraph questions, followed by classroom instruction. In the afternoon, we would have the opportunity to do labs and apply what we had been learning. The instructors had a wealth of knowledge and experience in the polygraph field and promoted a high quality learning environment.

Students who are committed and put in the effort to improve each day will graduate well prepared to conduct polygraph exams upon returning to their agency or business. Students leave PEAK with a variety of useful resources and contacts, which aid in conducting high quality polygraph exams. I highly recommend PEAK to anyone looking for a basic polygraph examiner's course. "

Bill Weisert
PEAK Basic Course

"I attended PEAK's basic training and PCSOT course, both of which I received excellent training. All instructors at PEAK care very deeply about the success of students and are consistently updating the program to ensure that only the best material is being taught. Although my time at PEAK was brief, I can say with confidence that I am fully prepared to begin my career as a polygraph examiner. Along with exceptional teaching I received, I cultivated many relationships with insightful individuals who share my interest in polygraph. I would recommend anyone to go to PEAK if they wish to pursue the highest quality of training!"

Adam Marsh
Online PLE Course

"I was briefly exposed to the PLE in my basic school back in 2008 and a few seminars at assorted conferences. However I never had the confidence to incorporate the channel into my decision calls until after this course. I know the schools these days are teaching the PLE in their curriculum but if you are an examiner with a few years behind you, I would take advantage of this course."

Kevin Maul
Online PLE Course

"I found this training to be very useful in refreshing my knowledge of the Utah CQT."

"I recommend this course to anyone who is interested in having a high quality training made by experienced professionals, who are eager to share their experience and expertise, so that graduates can develop the polygraph testing in order to obtain performance in their workplaces. "

Radu B.
Advanced Examiner's Course

"In March 2022 I attended the PEAK advanced examiner course. I have been a practicing forensic polygraph examiner for the past 10 years and I look forward to many more productive years to come. In an effort to stay current and updated in all researched and validated testing practices, principles and techniques I opted to attend PEAK after researching various programs. I was very pleased with the professionalism, enthusiasm and knowledge Ben and his fellow instructors shared with the class. The class structure and format was extremely user friendly and it promoted a comfortable and engaging atmosphere for mutual exchanges of positive ideas and insights among a classroom full of competent and confident examiners all with the mutual goal of self-improvement and gaining advanced knowledge in polygraph science. I highly recommend this advanced course to any examiner interested in enhancing their skill set and getting up to date and quality continuing education."

Eric Mawhinney
Advanced Examiner's Course

"This course was by far the best polygraph training I have received since polygraph school. If I had to do school over again, I would go to PEAK. Ben's extensive knowledge of polygraph history, research, and application was clear and he delivers everything in a way that is easy to understand and apply. The various topics were thoroughly covered with plenty of time and discussion for individual questions and "tricks of the trade" to help improve our skills as polygraph examiners. I highly recommend this course to any examiners looking to keep up with the latest, best practices in the field. If you're new to polygraph and looking for the right school, you just found it."

James Phelps
Detective- Clark County Sheriff's Office

"My express goals for attending PEAK's advanced course were:

  • to acquaint myself on any new issues pertaining to polygraphy since attending the basic polygraph course in 2015;
  • to realign myself regarding polygraph best practices; and
  • to adhere to national and regional polygraph associations' membership requirements regarding Continued Education Units (CEUs)

My goals were not only achieved, but exceeded my expectations by far.

It is my opinion that many, if not all examiners attending a PEAK advanced training course, will agree that attending Ben's advanced course imparts far more knowledge than can ever be obtained during any national and/or regional polygraph association conference.

Lastly, attending this course once again reinforced my belief that PEAK is (and remains) my training provider of choice."

Peter G, W5H Global Inc
Advanced Examiner's Course

"The training I received in this course was simply the best polygraph training I have had since becoming an examiner. The material is extremely relevant and helpful. The instructors were professional, engaging and challenging. As a result of this week, I feel I have been equipped with so much more knowledge and best practices to improve my craft in polygraph. Ben and his staff are incredible, they genuinely care about their students and are clearly dedicated to their success. I highly recommend this course to any examiner who wants to improve and develop ways to increase their ability with the challenges we all face in the polygraph suite."

Chris Conley

"I attended the Advanced Examiner's Course in March 2022. This was an excellent training opportunity that I highly recommend for anyone who has been to basic polygraph training and needs a refresher. Polygraph is constantly changing and evolving, and this advanced course is a necessary update to ensure best practices are being utilized. Ben is a highly qualified, engaging, experienced instructor; there is no better training out there. "

Glorianna Sauer
Advanced Examiner's Course

"I took the PCSOT Course and then the Advanced Polygraph Examiner's Course in the Spring of 2022.

All the staff are knowledgeable professionals with many years of experience. The training at this school is second to none. I will strongly recommend to all who want to enhance their skills. I found the training at PEAK to be especially beneficial to experienced examiners. The class led discussions provided an insight to the best practices being used all over the world. It is also great for networking and peer support beyond the class.

Sign up for the training. You will not be disappointed. "

Enrique Lopez
PCSOT and Advanced Examiner Courses

"Great job! Real hands on approach made the Advance Examiner's course enjoyable and educational. "

Scott Boshek
Advanced Examiner's Course

"Best polygraph school in the world! Top notch instructors! "

Darrell Hite

"I've been to several polygraph courses and none have been as informative as what PEAK offers. Ben is a phenomenal instructor. I will be recommending PEAK to my agency for future examiners."

Mike McNamara

"Attended a PCSOT course at PEAK in March 2022. Top notch training with excellent, experienced instructors. Would highly recommend PEAK for new and experienced examiners."

Rory Suby
PCSOT Course

"Like all the materials provided by PEAK, this course on DLST was very well structured and presented, including the explanatory videos of Ben Blalock, who is a true professional and a very good teacher. Also, it showed me that you always have something to learn, no matter how much professional experience you have. "

Radu Baboianu
Online DLST Course

"Very excited about this course. The information was well structured and documented. I consider that I have enriched my knowledge about DLST. "

Stejar Laura Simons
Online DLST Course

"Was a great course for a first time exposure or a refresher course. Very informative. "

Christopher Coffey
Online DLST Course

"Like all the materials provided by PEAK, this course on UTAH CQT 3 RQs was very well structured and presented, including the explanatory videos of Ben Blalock, who is a true professional and a very good teacher. "

Radu Baboianu
Online UTAH Course

"Concise, organized, easy to follow, practical, with statistical data that support the validity of the technique "

Stejar Laura Simons
Online UTAH Course

"This was a great refresher course as I haven't used the Utah technique in about 2 years. "

Christopher Coffey
Online UTAH Course

"I thought it was a Great Course, it is Good to read the Articles that the APA Provides and also the powerpoint slides. I felt like I learned so much out of this ACQT class, I took the DLST class last year and loved it, especially with my Job testing kiddo's with PSCOT. I will take more classes with Ben at Seminar's and also Online Courses."

Tony Reistroffer
Online ACQT Course

"This is the best post-basic examiner course I have been through. I have been through Peak's Advanced Examiner Course twice and I will not miss an opportunity to attend it again. Both Advanced Courses were different but they still covered everything I wanted to learn more about or refresh my skills on. Each course is tailored by the students because Ben asks everyone on day one what they want to cover or gain from the course. If you have not had an opportunity to attend one of these sessions or you have been wondering if you should, I can tell you, without hesitation, you should attend this course. You will not regret it and will come out with a wealth of great knowledge and materials that will make you a better examiner."

Aron Thompson
Advanced Examiner's Course

"I often get frustrated when I attend various polygraph training courses / national conferences, when I hear instructors giving differing opinions regarding scoring, proper test techniques, introduction of comparisons, etc. But whenever I have attended training provided by Ben Blalock and/or Peak Credibility Assessment, I walk away feeling like I have learned something new and have confidence that the information is correct. Ben has opinions like all instructors but he cites the research which supports what he is saying. Ben follows the science and explains things in a way that helps you understand. I highly recommend the Peak Credibility Assessment Advanced Polygraph Course for all polygraph examiners. I have attended this course twice and learned something new each time. I have applied what I have learned from Ben and I truly feel like I am a better examiner. Lastly, one of the best things about the advanced course is that on day one, Ben asks the class for a list of questions they have concerning polygraph. The topics are wide ranging and Ben makes sure to address all of those questions during the week of training."

Jon Eager
Advanced Examiner's Course

"I recently spent a week attending an Advanced Polygraph Course, instructed by PEAK Director Ben Blalock. Having been a law enforcement officer for 36 years, and a polygraph examiner for the past 15 years, I had settled into a group of scientifically validated testing formats that I routinely used. Among other things, Ben's instruction covered multiple testing formats, including formats that I have not used. Unlike some of the other classes I have attended, the science behind the subjects taught in this course was offered in a manner that was easily understandable to even this retired detective sergeant. After hearing the science and success stories from not only Ben, but others in the class, I will be adding another format to my go-to list. Ben's style of teaching was extremely helpful and informative, while at the same time gleaning knowledge and experiences from those attending the class. I highly recommend PEAK's Advanced Polygraph Course to other experienced polygraph examiners."

Monty Buettner
Advanced Examiner's Course

"I really enjoyed the Advanced Polygraph course this week. I learned more about the most accurate scoring method in the first two days than in my first couple of years as an examiner. I feel much more confident in scoring exams. The block of instruction on countermeasures will prove invaluable going forward in my ability to identify them being used in an exam."

Advanced Examiner's Course

"I just graduated from the Basic Polygraph Course at Peak and wanted to take a moment to express gratitude to the cadre and lab assistants for their hard work and dedication to the science of polygraph. I've worked in law enforcement over 25 years and have attended many schools and training courses. The quality of the instruction and the methods of training rank among the highest I've ever had the privilege of attending. You will definitely engage in this course, and you will learn by immersion which will be challenging but rewarding. After 400 hours of training, I feel ready to run both criminal and screening tests. I'd recommend this school to anyone looking to learn this critical skill used in a variety of capacities. I can't say enough good things about the quality of the instruction, the skill of the instructors, and the comprehensive education that was covered in these last ten weeks. You can't go wrong with this training."

Rhett J. Carter
Knoxville PD

"You won't find a better polygraph school! "

Elizabeth Alley
Dayton Police Department

"In my 25 plus years as a Federal law enforcement officer, the training and instruction I received at PEAK was by far the highest quality. It is an arduous program but well worth the results. The day I graduated from PEAK I felt more than qualified to conduct a polygraph exam and I felt I was equipped with the knowledge and skills to discuss with others the ins and outs of the polygraph field. Thank you to all PEAK instructors and Ben Blalock for his tireless dedication to this field! "

PEAK Basic Course

"My experience at PEAK was one of the most educational and impactful experiences of my life. I have no prior police or law enforcement experience and this school has completely prepared me for a future in polygraph. Whether I decided to work privately or with a police department, when I left PEAK I was confident and equipped with the most current and in-depth education that the United States had to offer. I made the decision to travel from California to Florida for 10 weeks and that is simply because it is the best school for Polygraph. The teachers and staff care immensely about their students' education and their well being during the entire duration of the courses. And I would highly recommend this school to anyone who is interested in polygraph or to anyone looking to further their education in the field."

Melanie Solberg
PEAK Basic Course

"Very informative and well presented research statistics."

Emile Blackman
Online PCSOT Course

"As expected, the online PEAK courses are outstanding. The next best thing to going to Cape Coral."

Zachary Aylsworth
Online PLE Course

"Thank you so much, Ben! This Advanced course opened my eyes and I realized that I have a lot of modifications to do. This class has enhanced my ability to become a better examiner! I will use the lessons learned to improve and teach/coach other new examiners. Thank you so much!"

Min Cha
Advanced Examiner's Course

"I've always been impressed with the quality & relevance of the topics covered during an advanced class at PEAK. Ben is an outstanding instructor who is a credit to polygraph."

Brent Turner
Rogers, AR

"I attended the PEAK advanced course in July of 2021. This course was exactly what I needed to increase my confidence with administering polygraph examinations. Ben answered all of the questions from students with patience and research based answers. The course addressed specific needs of the students in a way that guaranteed that every student leaves the training with better understanding. I recommend that every examiner take this course regardless of experience level. This was the best way for me to increase my knowledge of polygraph and met the requirements for continuing education."

Gary Nicholson
Pierce County, WA

"The course (PEAK's Advanced Course) was a perfect follow-up to update and supplement my existing training. Given that I travelled a significant distance, from a police agency in another country, for this course - my expectations were high. Ben didn't disappoint. He is clearly informed and passionate. He cited current research for every piece of instruction he provided. My agency will be benefiting from practical updates we will implement right away. Given the present and historical benefit of this training, the advanced polygraph examiner's course is now categorized as part of our agency's annual "Mandatory Training" for experienced polygraph examiners."

Advanced Examiner's Course

"I just wanted to thank you all for a wonderful week of great instruction (PEAK's Advanced Course). There were so many of my questions that were addressed and so many new things that I learned in a single week. Being a new examiner myself, and a recent graduate of another school, I am just envious of your PEAK graduates. The PEAK graduates in our class seemed equipped with the most updated information and studies, more confident to perform a test, and disclosed they performed more training exams than I did.

Regardless of where you went to school, Ben took the time to address everyone's concerns, teach what the class wanted to know/improve upon and even provided insight into upcoming changes that are soon to come. A week here is a definite investment in your polygraph career. Thank you all for helping me be a better polygraph examiner. "

Wes V.
Advanced Examiner's Course

"The PEAK PCSOT class exceeded my expectations. The instructors were extremely knowledgeable and the material they presented was comprehensive and pertinent. At the conclusion of the class, I felt well prepared to conduct PCSOT polygraph examinations."

Julie Webb
PCSOT Course

"I attended PCSOT training at PEAK in July, 2021. The training was informative, relevant, and up-to-date. Mr. Blalock and the entire staff at PEAK are top of the line polygraph examiners with a heart for teaching. They are truly passionate about the profession and art of polygraph. I attended the basic polygraph examiner training course at a different school a number of years ago. Mr. Blalock pointed out the "good" things I brought with me, and showed me, through an evidence based approach, how I can not only improve, but showed me how I can apply what I learned, starting today. Mr. Blalock's "best practice" approach to polygraph removes the "ego" out of polygraph instruction with researched based facts. I would recommend PEAK without any reservation."

Mike Weiss

"You are the instructor that gave your all to the polygraph cause. You are a really dedicated vet who is very knowledgeable and responsible about the way you teach PCSOT. You have shown tremendous responsibility and technicality during the entire course. I appreciated the tremendous effort you devoted to your polygraph courses and I hope PEAK can continue to thrive as a business along with the rest of your team."

PCSOT Course

"This class was amazing. Ben is knowledgeable in every aspect of polygraph and is excited to teach it. He is able to take complex topics and make them easy to understand and apply to daily polygraph work, and he keeps students engaged and interested the whole time. I highly recommend Ben's classes to anyone, regardless of where they attended basic polygraph school."

Abby Giampolo

"I recently attended the Post Conviction Sex Offender Testing class in Cape Coral, Florida. The director and instructor, Ben Blalock, taught the class, along with several other members of his staff. I have attended many polygraph training seminars/classes over the years, and I must say, Ben's class (PEAK) was by far the best. Ben is a well versed, highly intelligent and knowledgeable individual in the field of polygraph. Ben and his staff presented themselves in a highly professional manner, and were extremely kind and accommodating throughout the week. I would highly recommend anyone who is planning on taking any future polygraph classes to attend Ben Blalock's, PEAK, polygraph classes!!"

Anthony Stevens
PCSOT Course

"The 16 hour PCSOT Sexual Deviancy course was very informative. I'm looking forward to taking other courses with PEAK."

Eric Macolino
Online PCSOT Course

"I am so happy that I attended PEAK CATC for my polygraph training. The immersive learning environment and repetitive testing that PEAK adheres to has allowed my classmates and I to become competent and proficient polygraph examiners. At the end of the 10-week course, I feel very confident that I am ready to conduct polygraph exams."

Julie Webb
PEAK Basic Course

"This course was very beneficial in preparing me to be a polygraph examiner in the field. I am very thankful that we had the time and opportunity to run so many tests. The repetition was very beneficial. Ben is extremely knowledgeable and does a wonderful job in not only teaching the material, but in answering each and every question the students have."

Jenna B.
PEAK Basic Course

"PEAK Credibility Assessment Training Center was by far the most challenging training class I've attended since joining Law Enforcement. Since I graduated feeling confident that I can administer a Polygraph exam from start to finish, it was all worth it!"

Detective DeJesus
PEAK Basic Course

"I attended PEAK in 01/2021. The school was very overwhelming in the beginning, but you will look back and be thankful. The quality of instruction was great. PEAK gives you the opportunity to go above and beyond the minimum requirements for completing the course. PEAK provided a vast amount of resources and gets you connected with all of their graduates after the course to keep you connected, informed, and answer any questions. The director of the school was very involved. There were opportunities throughout the course to address any questions or concerns. I have nothing but great things to say about this school. I was able to return to my agency and make much needed changes due to the advancement in polygraphs. The examiner I work with attended a different school one year prior to me attending PEAK, and I returned with a higher level of polygraph knowledge and experience. The other school did not invest in the attendees like PEAK did. PEAK wants you to be the best examiner and take pride in your important work. I always felt cared for while attending PEAK."

Jake Gullion

James Rose
Online DLST Course

"I recently attended the 10-week PEAK Basic Polygraph training; the learning experience was excellent! The immersion style of teaching was a bit overwhelming at first, but by the end of the training, I felt very confident in my knowledge and abilities. The staff is top-notch and teaches the most current information in the field. I have been conducting polygraph exams for my agency and had a few curve balls thrown my way, but with the training I received, I was able to handle them with ease. I highly recommend PEAK!"

Don G.
PEAK Basic Training

"If you ever think you are up to date, just go to an Advanced Examiners Class through Peak Credibility Assessment! One of the most amazing things about this class is you get to have input on the subject matter discussed.

In addition, the most current, need-to-know information is provided throughout the course. The information and tools enable you to improve your skills and have confidence that you are current in the field.

Ben Blalock is an awesome instructor and one of the most well-known in the field. He has the unusual ability to take complex information and provide it in terms you will easily understand. This course is now marked on my calendar annually. It's a must attend!!!"

Noreen Pollock
Advanced Examiner's Course

"The training I received at PEAK was excellent. I was amazed at how many hours the instructors spent with all of the students. We were encouraged to conduct polygraph exams not only in class but before class, after class and the weekends. If you want intense, extremely informative training with the most up to date information this is the place for you. Upon completing the ten-week basic examiner course I was well prepared to perform polygraph examinations for my law enforcement agency."

PEAK Basic Course

"I recently attended your Advanced Examiner's Course and wanted to thank you for such excellent training and instruction. Despite the expense involved to travel from California to Florida to take a week long class, I found that it was worth every penny spent.

Your instructors were all excellent, and I commend Director Ben Blalock for all of the excellent information he covered in the class. I feel that I definitely came away with very useful information that should help me be a much more effective and knowledgeable polygraph examiner in my business.

I highly recommend your Advanced Examiner's Course to everyone! Thank you!"

Nate Perkins
Online Utah CQT Course

"Once again a well presented and informative course by Ben."

Rick Livingston
Online DLST Course

"This training presented by PEAK was easy to navigate and execute. The lecture was presented well and the reading material was very informative. I was able to leave the course and conduct other pressing matters that had interrupted the time frame I had scheduled for this training. I returned three days later and picked up where I had left off without any issues, working toward a successful completion. I highly recommend PEAK training courses to those searching for online polygraph examiner training that will be flexible for your busy schedule."

Paul Carter
Online DLST Course

"This was more like a college course than any training I have done since I attended basic polygraph training at Texas DOPS. I learned much more than in the past at the professional seminars I have attended. It required a lot of time and effort to complete, but was well worth it."

Tana B. Stone
Online DLST Course

"A very well done, albeit time consuming training. It also added a good refresher course in basic polygraph principles."

Sheril Mounce
Online DLST Course

"The course was an excellent refresher to the Peak Basic Course. The information was current and identified trends in polygraph examinations to include practical approaches to the challenges of polygraph examinations. Well done. Well presented."

Mike H

"When I initially signed up for the course I knew very little about Ben Blalock or PEAK Credibility. After completing the week long advanced examiners course I can say definitively that it was one of the best training courses I have taken. All of the instructors were knowledgeable and were able to draw on many years of experience within the polygraph field. Both the training and facilities were top notch. The advanced polygraph training course will now become a staple in my required yearly training for polygraph."

Chris McGillicuddy
Hillsboro Police Department

"I traveled down here from Springfield, MO for my continuing education. Ben Blalock was our instructor. Great training and refresher, taught me some things I was missing and will bring back to my agency. Thanks for the great week and I will be back. "

Detective Eric Rogers
Springfield Police Dept

"Thank you for the training this week. I am a huge believer in Polygraph regardless of the outside noise or agency belief and continuous command rotation. And thanks for entertaining a Backster Grad. PEAK went right along with my training from 2017. I highly recommend PEAK and look forward to sharing everything learned this week with my peer examiners. Thank you for the week. I will be back. "


"Being a PEAK graduate and coming back for advanced training makes me feel like I am home again. The material covered is the latest and greatest. Any question you have is answered, and if for the rare reason an instructor does not know, they find the answer for you. From the time I left basic and came back to advanced training, so much has changed, and I gained the information I needed to get back to my state with the latest and greatest information related to polygraph."

Joseph Ray
Advanced Examiner's Course

"PEAK Credibility Assessment Training Center (CATC) provides a real world hands on strategy using an immersion learning educational approach. For ten (10) weeks you will be submersed in a polygraph setting and environment, from the understanding of your polygraph instruments, to theory of the polygraph test, to proper scoring and selecting techniques (ACQT, UTAH, DLST, AFMGQT, and CIT, etc.) pre/post-test interviews as well as completing as many as eighty (80) plus polygraph exams. Director Ben Blalock along with his professional staff will motivate you with their own work related experiences using lectured based and group discussion to start your mornings followed by practical exercises. PEAK provides you with the best onsite equipment (LX6) as well as the most up to date validated techniques that will help you grow throughout the ten weeks as you continue through to the day of graduation. Upon completion of PEAK CATC course you will have all the competence and confidence to successfully interview, administer, score and properly report both screening and diagnostic exams.

I came to this class without any understanding or knowledge of polygraph and began administering DLST's day one upon my return back to my agency with confidence. PEAK will do the same for you.


Joe Vallor
PEAK Basic Course

"Like many others that have attended or will be attending this course, I was blind to what a Polygraph course would entail. I was advised by some colleagues that had taken the class that it would be hard and time consuming. They were right! I was overwhelmed with knowledge the first day. But let me tell you, every second spent training within and outside the class, learning the process, the hands-on training (you will get so much of this and it helps), and all the do's and don'ts made it worthwhile.

As soon as I graduated and got back to work, I was scheduled with a criminal test. I was very confident and excited going into this test because of the training I was given at PEAK. All of the instructors are top notch and go above and beyond to make sure you understand the material being taught. Thank you, Ben Blalock and PEAK Staff, for your hard work and dedication to making me one of the Best of the Best!"

Lieutenant Mary Brown
Florida Highway Patrol

"I am a proud recent graduate of PEAK Credibility Assessment Training Center, and I just wanted to share my feedback. The training offered by PEAK, was one of the most professional and well-presented training classes I have ever taken. I want to thank Mr. Ben Blalock and his amazing instructors for ten weeks of thorough and well-organized training. The training was superb, and I genuinely enjoyed each and every moment of it. The lectures were truly inspiring, and I particularly enjoyed the hands-on polygraph training, which made the content easily understandable.

I have attended several advanced training classes before, but I can't recall any of them having such a strong impact. You all have done a fantastic job, and I appreciate your efforts. I admit, it was a lot of information to digest in ten weeks, but it's worth it when you can leave the training with confidence of doing your first polygraph the same day.

I would like to thank everyone who was involved in the preparation and execution of this training. You have all done a fantastic job, and I look forward to attending future training given the opportunity.

Don't think twice about what polygraph school to attend; PEAK is the BEST."

Master Detective Tangelia Jackson
Hillsborough County Sheriff's Office

"Director Ben Blalock is a genius. He is an excellent teacher and his knowledge of polygraph is like no other. I went into the class not knowing anything about polygraph but left feeling very confident. My agency scheduled me for three polygraphs my first week back after I completed school. Rather than my main feeling being that of nervousness, it was more of excitement. That is because this class prepared me for it. It not only taught me about the polygraph instrument and sensors but everything else about it. The who, what, when, where, why, and the how. If I had to describe this class in one word, it would be 'immersive.' There are probably other schools out there that don't require as much work; but if you want to be one of the best polygraph examiners in the world, this is the school you want to attend. I can promise you that I will be one of the best in the world and that is because I attended PEAK."

Sergeant Merle Burkhart
Escambia County Sheriff's Office

"I had no idea what to expect coming into this class. The two people I spoke with regarding the class both told me PEAK was the best polygraph school around and it was a lot of work and I would have no time to do anything but the class. Boy were they right. The class was intense to say the least. Ben said the first day of class that we (the class) were going to be lost and overwhelmed but to trust the process. Ben was right, by the 4th week it all started to come together and it started to click. I had no experience coming into the class regarding polygraph but at the end, I feel confident I can run a polygraph. "

Robert Julian
PEAK Basic Course

"There's good, better, best, then the PEAK way. Ben Blalock and his entire staff are great. The amount of knowledge they each bring to the classroom is incredible. I came in knowing nothing about polygraph, now I have the confidence to start the day after I leave class. You can automatically tell Ben loves what he is teaching. He puts in his best effort to pass down onto us all the information we will need to strive in the polygraph field. I searched different polygraph courses, and asked people who they would recommend. Everyone said I would learn only the best at PEAK. I would highly recommend this course to anyone who wants to be a great polygraphist."

Juan Navarro
PEAK Basic Course

"PEAK is a savior with their online advanced polygraph courses! Had it not been for PEAK I would not have made a deadline to complete required CE hours for licensing. The cost of the course is a fraction of what I would of had to pay to fly out of state and attend a seminar or other venue. I was able to work at my own pace and I found the course to be very interesting! Thank you PEAK!"

James Hannah
PCSOT Course

"I found the PEAK course to be a very accommodating, practical and affordable solution to required advanced training hours. I was able to work at my own pace at home and not have to travel at tremendous expense. The course itself was very easy to follow and informative. Definitely will help with my future examinations, test reliability, and professionalism!"

James Hannah

"You will not regret any PEAK training you take. This school is very detailed, clear and current on the best practices with Polygraph. There is a lot of information to stay up-to-date and current on and PEAK is definitely the way to obtain it."

Jennifer Plymouth

"I have enjoyed and learned valuable tradecraft in both PEAK courses I have taken online. Although I prefer in-person conferences to learn, since the on-set of COVID19 and no conferences available, I have learned to enjoy pacing myself through PEAK's online training. The staff are very respondent and professional. I look forward to my next online class. "

Robert J. Smith

"The best and sincere reasons I could give for advocating PEAK's online training course: (aside from far-off travel) The convenience of being able to take the course at one's leisure (within a reasonable set time-period). The providing of PEAK's complete and concise class-notes, power points and videos which can be continuously reviewed (once again at one's leisure), The opportunity to work in a group format by sharing information with on-line seminar attendees, And most of all: The amount of time the student has in which to ponder, reflect and respond to the topics and questions posed to them in an non-rushed atmosphere that one really cannot enjoy when physically present at a venue."

Mark S. Ralton

"This was my second PEAK online course and it will not be the last. There was so much valuable information provided that will be useful in future polygraph exams. I found this course to be very thorough, thoughtful (explaining specifically why the ACQT is so important - and there are many reasons), and helpful in terms of preparing you to put the knowledge into action. The course addresses APA Standards of Practice relating to ACQT's. I recommend this course to all polygraph examiners, regardless of your level of experience."

Rob Diekman
Online ACQT Course

"This is the first PEAK on-line training I have completed... but I plan on taking more courses soon. I found this (DLST) on-line course extremely informative and helpful in many ways. I think there was a good balance between information topics: research, history of DLST, considerations for all steps of the polygraph process (preparation, pre-test interview, informed consent info/ROI, office environment considerations, screening exams in general for public service use... I could go on and on).

I'll try and summarize: If you are looking for an extremely thorough presentation of the DLST and using screening exams for pre-employment testing in general, cough up $150 (small price I think), grab an awful lot of paper (I took 24 pages of notes), a couple pens/pencils, and settle in for what I think you will find to be a very practical and helpful learning opportunity/experience. This is a solid 5 star course in my humble opinion."

Rob Diekman
Online DLST Course

"The PEAK PCSOT course was one of the best courses that I have ever taken. This course was very well designed with great information, the right expert subject matter speakers, as well as knowledge applicability. Thank you for such a great course and your endless dedication to this field."

Noreen Pollock
PCSOT Course

"Extreme thanks, to director Ben Blalock and the entire PEAK staff for an amazing course. The week was filled with comprehensive information and truly prepares an examiner to "Hit the ground running." PEAK's ethics, professionalism, and teaching ability are beyond reproach. An examiner who graduates from a PEAK course, is an examiner who is ready to test in the field. PEAK continues to be an asset to the field of polygraph testing and an outstanding training center."

Antonio V. Torres IV
Miami Police Sergeant (Retired)

"Peak Credibility Assessment Training Center (Peak CATC) is my agency's choice for all polygraph examiner training. As the fourth student attendee, I was told it would be an intense 10-weeks. It was!! Ben Blalock and his cadre are phenomenal. This was like no other law enforcement training I've done in my 23-year career. I was told it would be like drinking from a firehose and it surely was, but I could not have had a better experience.

After graduation, it was seven (7) weeks before I ran my first actual polygraph examination due to COVID-19 measures. The intensity and muscle memory this class instilled in us made my first polygraph a breeze. I overcame the obstacles each polygraph examination presents and had a very successful examination. With each examination since, the challenges of polygraph examinees have been nothing but a blip on the radar due to the thorough and intense training I received at Peak CATC. Thank you Ben, Scott, Jim, and Sandy. WWBD?"

Michael H.
Okaloosa County, FL

"I finished your online course on the acquaintance test. I want to commend all of you on excellent work. Even though I am an experienced examiner, I learned some new things and had some old ones reinforced. I do plan in the future to take another one from you and hope that you will continue to add new courses. I believe that online polygraph courses like yours are the wave of the future. Your course made me feel that I was communicating with a real and professional person who has the same values as I do."

Gerald Carter
Online Acquaintance Test

"I would like to take this opportunity to comment on the Polygraph Advance Course in Cape Coral, Fla last week by Peak that I attended. Ben Blalock did an outstanding job with the course. This training was especially beneficial for me as I needed updating on polygraph issues. Peak is one of the few polygraph schools that offer an advance course which I think is very important. Ben was very thorough and presented the material in a very professional way. Even though I have been an examiner for many years I benefited a great deal from this training. I would certainly recommend this course to all examiners especially those who have been in the field for a number of years."

Von Jennings
Advanced Examiner's Course

"PEAK Credibility Assessment Training Center was recommended to me by two polygraphers and work colleagues. After speaking to Ben Blalock and visiting the school, I knew that it was going to be the right school for me. I have worked in several different specialty units throughout my law enforcement career and it always took me about a year to really feel comfortable in a new position. I am amazed by the confidence that I have going into a completely new field as a polygraph examiner after just 10 weeks of training. PEAK has been an incredible learning experience with full immersion into the world of polygraph. Ben's knowledge and passion for polygraph is inspirational. He has surrounded himself with a talented team of instructors who are all genuinely concerned with every student succeeding.

PEAK does not just teach you how to administer a polygraph, they teach you the how and why of every aspect of polygraph. They also teach you the best practices in the field. I have no doubt that I have received the best training available anywhere. I cannot recommend PEAK highly enough. I will continue to build the skills I have acquired here and continue with advanced training through PEAK as often as possible to keep up with this ever-changing field."

S. Dunn
PEAK Basic Course

"I feel that PEAK does an excellent job of teaching the students. The instructors that are available to students go above and beyond to make sure that we understand the material. Ben Blalock is not only a exceptional instructor but an even better person. He will push you to the limit of what you think you can learn and then take you beyond that. It is not often in Law Enforcement training that you get to be associated with instructors that seem to have a vested interest in your education success.

The best way thing I could say about PEAK is that if I was to have a test administered to me, I hope that the person running the test is a PEAK graduate, because I know that they will be the best and do it right EVERYTIME. "

Tyson Estes

"PEAK CATC was a very challenging and intensive course. Over the course of ten weeks, I went from knowing very little about the theory and application of polygraph to feeling very knowledgeable and competent in both the principles behind the process as well as conducting the actual examinations. The instructors were all very passionate in their instruction and were very helpful in making sure the students thoroughly learned the material."

Anthony West
PEAK Basic Course

"Polygraph as a discipline has issues with dinosaur-ism...practitioners who do things the way they were trained, frequently many years ago, with no room for growth, education or expansion. The great thing about coming to PEAK is that you don't have to take anyone's word for anything. They show you the science, they back up their curriculum, and they push-up-to-the-minute scientifically validated techniques. There were two major changes to best practices just while I was in school, if that gives you any idea. Their instructors are long-time examiners, whose names are associated with nationally known cases, significant case law, and cutting-edge research. They tell you straight out if something they used to teach was wrong, and why they changed. Their adaptability to new research findings, leadership in the field, and decades of combined experience make PEAK the obvious choice for basic course instruction and continuing education. If you trained somewhere else, don't worry...their advanced course will be an eye-opener for you, and they will fix you up without judgement. Their basic course is not for the faint of will work and work hard. But you'll also leave a better polygraph examiner than 95% of the rest of the world, with the most current education available. Do yourself a favor and go to PEAK."

Greg Grannis
PEAK Basic Course

"This was one of the most challenging and awarding classes I have attended in my Law Enforcement career. I feel very confident entering the Polygraph community. Highly recommended class! "

Capt. Cleven (C.J.) Remondet III
St. John Sheriff's Office - Laplace, Louisiana

"Wow, great class. To Ben and all the instructors, thank you for your hard work in teaching us the best practices for today's polygraph. The training has made me feel prepared to get right into the field and start administering polygraph examinations. I look forward to returning to PEAK for advanced training classes in the future to make sure we continue to keep using best practices when it come to completing examinations. Thank you again for your dedication to polygraph and time dedicated to teaching."

Detective James Langton
Fort Myers Police Department

"Whether you are an experienced examiner or someone new to the profession, I would consider PEAK Credibility Assessment Training Center to be the premier location for polygraph instruction. The instructor's have a wealth of knowledge and experience which they are not hesitant to share. The polygraph concepts taught here are leading the industry and based on proven scientific methodologies. After completing the 10 week basic course I can say that I walked away feeling 100% confident in my ability to conduct thorough and reliable polygraph tests."

Chris Gorrell
PEAK Basic Course

"Being new to the polygraph world, I had no idea where to start. In searching Google for schools, there were choices all over the country, but I had no idea what differentiated one school from another. In speaking with the polygrapher who offered to intern me, he knew and recommended that I speak with Ben at PEAK Credibility. He spoke highly of Ben and said that he ran the best school that I could go to. I immediately spoke with Ben, and subsequently made my decision to attend PEAK. I will always be grateful for the excellent training that I received here. I can confidently go into this new business with no qualms about my skills and truly believe that I can begin at the top, and remain there, with the continuing education that is also available through PEAK. There truly is no better way to learn polygraph than from PEAK."

Jeanna Field, Esq.
Managing Partner, East Coast Polygraphy, LLC

"I recommend the PEAK Credibility Assessment Training Center to anyone who is ready to be a world class polygraph examiner. After completing PEAK's basic training course I'm ready and more than confident enough to conduct criminal and screening examinations using scientifically proven polygraph methods. All of the PEAK instructors are experts in the field of polygraph and also dedicate themselves to thoroughly teaching every aspect of this subject matter. Everything pertaining to polygraph was covered in great detail while quality hands on usage of polygraph equipment was consistent throughout this course. Thank you PEAK Team!"

Eli Barton
Baldwin County Sheriff's Office

"I am a graduate of the USAMPS program in 1985 and was a polygraph examiner; polygraph examiner supervisor; and polygraph Quality Control Manager for NCIS until 1999. I was also a polygraph examiner for the US Postal Service-Office of Inspector General from 1999 until I retired in 2003.

I became employed with the Charlotte County Sheriff's Office as a part-time Cold Case Detective in 2009 and in 2013 was asked to implement a polygraph program and conduct pre-employment and specific issue polygraph examinations. I attended a Senior Polygraph Examiner Course presented by the NCCA in 2013 in order to become re-familiarized with the instrument. Since that time there are now three other Detectives here that have all attended the PEAK basic examiner training and have all been extremely impressive with their abilities coming out of the training and immediately being able to conduct quality examinations.

I recently attended the Advanced Examiner's Course held at the PEAK Credibility Assessment Training Center in Cape Coral which was presented by Mr. Ben Blalock, Director at PEAK. Throughout my polygraph career I have attended numerous training seminars and I must say that Ben's course and his method of instruction has been one of the most interesting and well- presented courses that I have ever attended. This was the first course I've attended outside of the Federal government and I was eager to learn what the non-Federal examiners were being taught. Ben is extremely knowledgeable about the field of polygraph and an excellent instructor. He not only presents current information based on scientific studies of polygraph and techniques, but sought information from the group of advanced examiners and their experiences. The entire program was excellent and I personally came away with a wealth of new knowledge that will be extremely useful in future examinations. "

Charlotte County Sheriff's Office

"This course was the most challenging, yet fulfilling thing I have ever done in my lifetime, besides graduating from the United States Marine Corp boot camp. The class work was intense at times, but Ben Blalock never allowed any of us to doubt ourselves. The other instructors, Scott Walters, Jim Orr, and the many other instructors used for the course were all amazing. If you are considering a career as a polygrapher, Peak is the only place you should consider."

Andre B. Sisson

"I had the opportunity to attend a much closer polygraph school about 20 minutes from my home. However, thanks to a close friend and another senior polygraph examiner I was encouraged to attend PEAK, which was clearly on the opposite end of the coast. I was very skeptical about committing to a large investment in terms of tuition, equipment, transportation, housing, etc.. This by far was the BEST choice I ever made. It was very interesting to see examiners visit PEAK during our course even though they had previously completed a course elsewhere and have them state they did not learn nearly half of what PEAK teaches.

I have no regrets and would definitely do it again. The quality of instruction and the instructors were by far the best. The instructors REALLY are very knowledgeable, reputable, and care about the students. Their backgrounds alone are highly reputable. My fellow graduates were all great and we have created long term friends. You will definitely graduate and be confident enough to start conducting quality polygraph exams. If you want quality evidence-based instruction and no regrets PEAK is the best in the world!"

Tommy Tallagua
Retired Parole Agent

"In the 25 years I have been a police officer; after all the years of training, certifications, and advanced training, I have never been to a more thorough, comprehensive and well instructed course as this one. The course is demanding, intense and very rewarding. The level of experience of the instructors alone provided a well-rounded course of instruction that was understandable and easy to follow. Ben Blalock has put together the best course curriculum and weekly outline that slowly brings everything in to perspective, so you really feel you are learning something every step of the way. No student is left behind. The course uses audio, video and kinesthetic teaching techniques to appeal to every type of learning modality. There are no stupid questions. The instructors answer your questions in such a way that you feel they truly care about you having the information without making you feel nervous about asking another question. Only the most up to date material is taught so by the end of the course you truly feel prepared to go out and administer a polygraph to someone with confidence.

Ben Blalock is a leader in the field of polygraph and has a wealth of knowledge he is excited to share with new examiner trainees. After ten weeks, the day I received my certificate and was able to walk out with the title of examiner was one of the proudest days of my life. This could only be achieved by the tremendous support of Ben and his experienced staff of instructors."

Ofc. Patty Morgan, Ret.
Titusville Police Department

"It was the best training I have had since graduating from polygraph school almost 17 years ago. Ben is excellent instructor and an expert in the field of polygraph."

D/F/Lt. Andrew P. Longuski

"While the PEAK Basic Examiner's Course covers all aspects of polygraph, I appreciated the particular focus on the practical application of polygraph examinations and chart scoring. PEAK also provided excellent study tools and exercises that made it easy to learn and retain the course material. I came to the program with no previous polygraph experience, but after ten weeks of training at PEAK I feel confident to return to my department and immediately being administering diagnostic and screening examinations.

Ben Blalock is an excellent instructor who uses patience and positive motivation to help pass on his extensive knowledge of polygraph to students. Ben, along with all the instructors and staff at PEAK, made this training a very positive and rewarding experience. "

Lars Teigen
Snohomish County Sheriff's Office

"The experience that I have had at Peak Credibility Training Center has been an amazing experience. The class is a total immersion into the field of polygraph right from the start. Ben Blalock is an exceptional teacher with a passion for the polygraph field. All the instructors at the course were extremely knowledgeable, all with an extensive background in polygraph. The instructors push you to learn about the field of polygraph and motivate you to be the best you can be. All the motivation and encouragement to learn give an examiner the knowledge, skills and confidence to take with you to the field."

Marc Wynia
Minnehaha County Sheriff's Detective

"These past weeks sure have been a challenge, but I am honored to have been given the opportunity of having been taught by some of the world's best. I am impressed with the dedication and professionalism of the PEAK instruction team. The instructors thoroughly covered the topics and gave us instructions that would have taken a long time to master out in the field. I feel confident that I can hit the ground running.

I am glad I did my research on polygraph schools. For those considering a career in polygraph, you won't be disappointed coming here. "

Chief Michael Hall
Manchester Vermont Police Department

"The basic course at PEAK Credibility Assessment Center is very challenging. There is a tremendous amount of information to cover in ten weeks, but Ben Blalock and his instructors provide the information with presentations that are clear and interesting. From day one, you are getting hands on experience. Ben's passion for polygraph and excellence are demonstrated by his tireless efforts to provide the best teaching environment and tools for his students. The instructors at PEAK present the most current, scientifically supported methods and best practices for the field. Additionally, Ben and his staff have an incredible amount of real world experience that they freely share, to teach and inspire students. After successful completion of this course, you are ready to go into the field. "

Patricia Orr
Tampa Polygraph Services, LLC

"Along with everyone in my class, I am extremely impressed by each instructor and the entire course curriculum. Before attending this course, I was told by several polygraph examiners that Ben Blalock is the tip of the spear when it comes to directing and instructing a polygraph course. They were correct. All of our instructors are knowledgeable and each has many years of experience either in the military, federal government, law enforcement and the private sector. All have shown their dedication to teaching and each has been extremely willing to go above and beyond to help every student grasp the technical concepts and build skills needed to be effective polygraph examiners. I am very happy to have selected Peak as my school of choice."

Chad Courtney
Auburn, CA

"My experience at PEAK has been nothing short of amazing. Ben is the best instructor I have ever had in my 11 years in law enforcement. He is passionate, extremely knowledgeable, kind, humble, and motivating. The days flew by because he made learning so interesting and fun. I HIGHLY recommend PEAK over any other polygraph school out there."

Kishia Veigel
Northport Police Department

"My time learning to become a polygraph examiner at the Peak Credibility Assessment Training Center was challenging to say the least, but it was the best law enforcement course I've ever taken in my 15 year career. The class material was based off of empirical scientific data and delivered in a way that was understandable. The most beneficial part of this class, in my opinion, was the hands-on portion. Being able to use the equipment from day one was very helpful. By the end of this course I was confident that I could walk out of the door and run polygraph examinations without any reservations.

The Director, Ben Blalock is an exceptional practitioner in the world of polygraph. The Peak instructors are the best in the world and the Lafayette staff quickly answered any hardware/software issues that arose during the course.

I would recommend the Peak Credibility Assessment Training Center to any agency in the country needing top tier polygraph examiners to conduct criminal and pre-screening examination at their respective agencies. Thanks again to the Peak Team! "

Christopher Maki
Northport Police Department

"During this 10 week basic polygraph course, Ben Blalock, along with all the other teachers, displayed subject matter knowledge, passion, and a desire for all students to succeed. Ben's dedication is encouraging and results in students excelling beyond what we ever expected. I have had many teachers and professors throughout my life, but have never had one genuinely care about the students, and the subject, so much. Not only is Ben committed to success in training, he and his group of instructors have developed a forum where alumni can reach out to instructors and previous graduates when in need of assistance. Ben's goal, and mine, was to be able to hit the ground running when I return to my agency. As a result of the amount of time allowed for hands on testing, I feel I am ready to tackle whatever is waiting for me. The Hillsborough County Sheriff's Office has entrusted Ben with the training of numerous polygraph examiners, and as a result of the quality examiners returning from Ben's training, I believe they will rightfully continue to entrust Ben with this great task."

Jose Hursey
Hillsborough County Sheriff's Office

"Ben Blalock is one of the most talented polygraph educators available today. I highly recommend him."

Dr. Charles N. Painter
Former Director, NRO Polygraph

"Ben has a way of explaining an entire process, so that it just makes sense and provides one with plenty of examples of how to administer the exams and interpret the charts. His energy is unlike any I have seen from any instructor and he makes the class interactive and engaging by encouraging audience participation. One does not receive just a lecture but a free flowing forum where ideas are exchanged all with the intention of making the material work for the polygraph examiner. He encourages feedback and discussion.

Since meeting Ben, on numerous occasions I have asked him specific questions via email or telephone. I did not even attend Ben’s introductory class, but he has treated me as if I was a long time alumni of the program."

Detective Dan Templeton
Seattle Police Department

"What I found in Ben as an instructor was genuine humility and sincerity and a hands-on personal approach. For Ben and his team, it’s all about training QUALITY future instructors and doing justice to the future of the polygraph industry."

Peter G.

"With the continuing professionalization of polygraph, competent examiners understand the underlying science and are able to skillfully apply this knowledge to obtain the best possible results. Ben Blalock’s method of instruction results in examiners that know how to stay abreast of developments in polygraph and remain able to conduct state-of-the science examinations that withstand professional, scientific, and legal scrutiny long after graduation. Ben’s graduates are able to hit the ground running confidently upon entering the field. I have a background in multiple forensic disciplines. It is critical for me to be able to explain why I am applying a specific solution to a set of circumstances.

Ben has enabled me to reach outcomes when other examiners, trained elsewhere, have been inconclusive with the same examinee on the same case."

Detective Tom Coffey
Chicago Police Department

"Ben has a wealth of experience and is a great instructor. The other instructors that he introduced and used were also very capable and all of the instructors were passionate about polygraph and committed to the profession. I have had several occasions where I called him to ask a question about a particular case or test that I needed to conduct. He always welcomed my questions and was extremely insightful and helpful in these instances. He has been a constant and continued source of advice for me, and I know also for many other examiners."

Scott Wiegmann
Former FBI Polygraph Examiner

"I am very confident and comfortable in saying that the training I have received from Ben Blalock has been the best. Mr. Blalock uses hands-on training techniques that are taught in a way that are easy to master and remember due the handouts he provides and the thorough and easy to understand explanations he uses."

Sean Matheny
A-1 Expert Polygraph LLC

"As a former teacher and businessman, I recognize excellent skill sets; Ben Blalock and his Instructors are masters at teaching polygraph."

"My polygraph instructors instilled in me the importance of integrity and ethics and how important it was to maintain them. They would be important to my career and to the Polygraph community. Many names became familiar to me through my instructors as Polygraph professionals and as leaders that I can trust and turn to during my Polygraph career. One name in particular was Ben Blalock. I quickly realized why that was. His name appeared on top of many research papers published in many Polygraph journals. I also noticed that his name appeared along with many other Polygraph researchers and scientist. It struck me that Ben Blalock was in many cases a direct competitor of my instructors in business of Polygraph Training Academies, but they repeatedly gave him accolades. It was clear that they and Ben Blalock had one thing in common, the advancement of polygraph science.

I still have the occasional question in regards to my Polygraph examinations. One of the individuals I will turn to for an answer or suggestion is Ben Blalock. His quick replies are amazing. We all get busy in our duties, but he has always taken the time to address my questions."

"I was told about Ben's enthusiasm and teaching style by other polygraph examiners prior to attending Ben's course on PCSOT. They were right. Ben is a great instructor. He involves his students and engages them in his class. I can tell you that he goes above and beyond and truly wants all of his students to be the best in the field.

I have contacted Ben with questions on Test Data Analysis and question formulation since attending his course. I am very impressed with his teaching style as well as his follow up to questions after attending his class. He has always responded in a timely manner even though I know he is very busy."

"Ben’s team of instructors are second to none and have varied backgrounds so you gain a wealth of knowledge and have the confidence that you will be an excellent examiner the very first time you conduct a live criminal or pre-employment exam. I am a private examiner, and anytime I have had a question, Ben and Gil have been more than willing to help."
