Not everyone claiming to be an expert is trustworthy. This alert examines the John Grogan case and why choosing a genuine professional for your lie detector test is essential.
This fraud alert examines documented evidence surrounding John Grogan's polygraph credentials — including his honorary certificate from an unaccredited institution, denied professional memberships, media misrepresentations, and testing practices that violate established industry standards. Protecting the public from unqualified examiners is essential to maintaining the integrity of the polygraph profession.
TL;DR — The Short Version
- John Grogan's 2004 polygraph training certificate from ACFS was described by institution owner Joseph Paolella as honorary and explicitly not intended to qualify anyone as a polygraph examiner.
- Grogan does not hold credentials from any APA-accredited training program, which requires a minimum of 400 classroom hours of instruction.
- The Global Polygraph Network denied his membership application in 2005 because he could not document attendance at an accredited polygraph training program.
- On his GPN application, Grogan claimed graduation from the 'American Academy of Forensic Sciences' — a professional membership organisation founded in 1948 that has never been a training facility.
- His television polygraph demonstrations violate APA and ASTM Standards of Practice, which prohibit testing in front of live audiences and require multiple chart collections scored with validated algorithms.
- He has offered lie detection services over the phone — a scientific impossibility since polygraph requires physical sensors attached to the examinee's body.
- California does not require a polygraph licence, but Grogan would not qualify for licensure in any state that does require one.
- Always verify a polygraph examiner's credentials through the APA, state licensing boards, and professional organisations before hiring.

Training Claims and the ACFS Certificate
What Is the American College of Forensic Studies (ACFS)?
ACFS was a Los Angeles-based institution located in the Koreatown/Westlake district that was never accredited as a polygraph training school by the American Polygraph Association [6]Verified Avoid Lie Detector Testing Fraud/Scams — Global Polygraph Network
Confirms GPN guidance on polygraph fraud avoidance, 90-95% accuracy range for properly conducted specific-issue testing, and consumer protection steps. The institution's legitimacy was further called into question when, in 2015, a federal grand jury returned a 21-count indictment against three individuals — including ACFS owner Hee Sun Shim — for running a 'pay-to-stay' scheme through ACFS and affiliated schools [7]Verified Three Indicted For Operating 'Pay-To-Stay' Schools
Confirms ACFS was involved in federal immigration fraud indictment, part of pay-to-stay scheme, 21-count indictment.
The U.S. Department of Justice alleged that ACFS and its sister institutions collected more than $6 million a year in 'tuition' payments from foreign nationals who were not bona fide students and never attended classes [8]Verified Feds Bust Alleged Student Visa 'Fraud Ring' in LA
Confirms $6 million annual tuition fraud, unannounced visits to ACFS, details of pay-to-stay scheme. When federal investigators from HSI's Student and Exchange Visitor Program paid an unannounced visit to ACFS, they found only one religion class in session with a single student present — despite SEVIS records indicating more than 300 foreign students were enrolled [9]Verified ICE Investigation — Unannounced Visit to ACFS
Confirms unannounced visit to ACFS found only one student in one class despite 300+ enrolled foreign students. Hee Sun Shim subsequently pleaded guilty to conspiracy and immigration document fraud and was sentenced to 15 months in federal prison [10]Verified Owner of LA Schools Pleads Guilty to Federal Fraud Charges
Confirms ACFS owner Hee Sun Shim pleaded guilty to conspiracy and immigration document fraud. This is the institution from which Grogan received his sole known training certificate.
The Honorary Certificate and Paolella Letter
In 2004, Grogan received what was described as an 'honorary' polygraph training certificate from ACFS after completing fewer than 100 hours of training [1]Verified John Grogan Fraud Profile — Global Polygraph Network
Confirms GPN's investigation of Grogan including ACFS certificate details, GPN membership denial in 2005, AAFS training claim, and absence of accredited training documentation. Joseph Paolella, the owner and operator of ACFS at the time and a former U.S. Secret Service polygraph operator, wrote a letter directly addressing Grogan's certificate [5]Verified Dr. Phil Replaces Jack Trimarco with John Grogan, Whom Trimarco Called 'a Fraud'
Confirms Trimarco's 2008 on-air denunciation of Grogan on the Tom Leykis Show, Grogan's 2009 defamation lawsuit, and Paolella's status as former Secret Service polygraph operator. In this correspondence — which is public record — Paolella made the critical point that the certificate was not intended to qualify recipients as polygraph examiners [3]Verified Is John Grogan, the 'Lie Detector Guy,' Scamming Everyone?
Confirms media coverage of Grogan credential concerns, Trisha Paytas testimony, Scott Cramer investigation, Paolella letter contents, and RHOC Season 19 appearance.
The contrast between Grogan's honorary certificate representing fewer than 100 hours and the rigorous requirements of legitimate training could not be more stark. Anyone who bypasses the proper training process and claims professional qualification risks causing real harm to the people they examine. Understanding how to spot fake polygraph certificates is an important consumer protection skill.
The AAFS Misrepresentation
On his application to the Global Polygraph Network, Grogan claimed graduation from the 'American Academy of Forensic Sciences' [1]Verified John Grogan Fraud Profile — Global Polygraph Network
Confirms GPN's investigation of Grogan including ACFS certificate details, GPN membership denial in 2005, AAFS training claim, and absence of accredited training documentation. This claim is fundamentally misleading. The AAFS is a professional membership organisation founded in 1948 and headquartered in Colorado Springs, Colorado [11]Verified American Academy of Forensic Sciences — Wikipedia
Confirms AAFS is a professional society founded in 1948 with members from 70+ countries, focused on advancing forensic science — not a training institution. It is a multidisciplinary professional society with over 6,600 members from all 50 US states and 71 other countries [12]Verified American Academy of Forensic Sciences — History
Confirms AAFS has served 6,600+ members since 1948, representing all 50 US states and 71 other countries. Crucially, the AAFS is not — and has never been — a training facility of any kind [11]Verified American Academy of Forensic Sciences — Wikipedia
Confirms AAFS is a professional society founded in 1948 with members from 70+ countries, focused on advancing forensic science — not a training institution. It is impossible to 'graduate' from the AAFS because it does not offer educational programmes that confer diplomas or training certificates.
Documentation from 2008 litigation reportedly produced a training certificate bearing the AAFS name but signed by Paolella, the ACFS operator — raising serious document authenticity concerns [5]Verified Dr. Phil Replaces Jack Trimarco with John Grogan, Whom Trimarco Called 'a Fraud'
Confirms Trimarco's 2008 on-air denunciation of Grogan on the Tom Leykis Show, Grogan's 2009 defamation lawsuit, and Paolella's status as former Secret Service polygraph operator. The confusion between 'ACFS' (American College of Forensic Studies) and 'AAFS' (American Academy of Forensic Sciences) may appear to be a minor typographical distinction, but claiming credentials from a prestigious professional society one has never been affiliated with is a significant misrepresentation.

APA Standards: What Legitimate Polygraph Training Requires
The 400-Hour Minimum Standard
The American Polygraph Association sets rigorous standards for its accredited training programmes. Individuals who attend an APA-accredited programme must complete a minimum of 400 hours of in-residence study [13]Verified CIA Polygraph Examiner Requirements
Confirms APA-accredited programs require minimum 400 hours of in-residence study completed in 10-17 weeks with 95% instruction by recognised faculty. This study must be completed within 10 to 17 weeks, and at least 95 percent of all instruction must be delivered by a recognised faculty member [13]Verified CIA Polygraph Examiner Requirements
Confirms APA-accredited programs require minimum 400 hours of in-residence study completed in 10-17 weeks with 95% instruction by recognised faculty.

Confirms APA-accredited basic course consists of minimum 400 hours covering validated techniques, scoring systems, and practical examinations.
Curriculum topics at accredited programmes include the history and development of deception detection, physiology and psychology of deception, validated polygraph techniques, question construction rules, data analysis using validated scoring systems, ethics and professional standards, legal frameworks, and practical mock examinations under field-like conditions [14]Verified PEAK CATC Basic Polygraph Training Course
Confirms APA-accredited basic course consists of minimum 400 hours covering validated techniques, scoring systems, and practical examinations. Students must successfully complete weekly written examinations, maintain a minimum grade point average, and pass both final written and practical examinations [15]Verified The Polygraph Institute — Course Curriculum
Confirms 400-hour in-residence curriculum with weekly exams, 75% minimum grades, and practical examination requirements.
Following graduation, examiners typically undergo an internship period before becoming fully certified. They must then maintain their skills through continuing education — the APA requires practising examiners to complete a minimum of 30 continuing education hours every two years [16]Verified Policy for APA Continuing Education Hours
Confirms APA requires practising examiners to complete minimum 30 continuing education hours every two years. Research has consistently demonstrated that polygraph accuracy depends critically on properly trained examiners using validated methods [17]Verified A Study of the Validity of Polygraph Examinations in Criminal Investigation
Foundational research relevant to understanding that polygraph accuracy depends on properly trained examiners using validated methods.
The Gap Between Requirements and Grogan's Credentials
The contrast between these rigorous requirements and Grogan's honorary certificate from an unrecognised institution — representing fewer than 100 hours of instruction — is stark [1]Verified John Grogan Fraud Profile — Global Polygraph Network
Confirms GPN's investigation of Grogan including ACFS certificate details, GPN membership denial in 2005, AAFS training claim, and absence of accredited training documentation. Grogan has no documented affiliation with any APA-accredited training programme [1]Verified John Grogan Fraud Profile — Global Polygraph Network
Confirms GPN's investigation of Grogan including ACFS certificate details, GPN membership denial in 2005, AAFS training claim, and absence of accredited training documentation. He is not eligible for membership in any professional polygraph organisation, including the APA, the National Polygraph Association, or the California Association of Polygraph Examiners [1]Verified John Grogan Fraud Profile — Global Polygraph Network
Confirms GPN's investigation of Grogan including ACFS certificate details, GPN membership denial in 2005, AAFS training claim, and absence of accredited training documentation. As a result, he cannot benefit from the advanced and continuing education offered by these organisations.
Consumers should understand that the science of polygraph testing has a rich heritage stretching back over a century. John Augustus Larson created the foundational polygraph technology in Berkeley, California in 1920, launching an era of scientific criminal investigation [18]Verified John Augustus Larson (1892–1965)
Confirms Larson created the foundational polygraph technology in Berkeley, California in 1920, launching an era of scientific criminal investigation. Modern polygraph science has advanced enormously since then, with validated scoring algorithms, evidence-based testing protocols, and rigorous quality controls — all of which require extensive training to master. When examiners bypass this process, the results they produce cannot be relied upon. Learn more about legitimate examiner standards in our polygraph examiner continuing education guide.
Professional Rejections and Denied Memberships
The Global Polygraph Network Denial
Professional memberships serve as important validators of a polygraph examiner's credentials. They require documentation of training, adherence to ethical standards, and peer review. When an individual is denied membership, it speaks volumes about their qualifications.
In 2005, John Grogan applied for membership to the Global Polygraph Network (GPN), an organisation established in 1987 that maintains standards for polygraph practice [1]Verified John Grogan Fraud Profile — Global Polygraph Network
Confirms GPN's investigation of Grogan including ACFS certificate details, GPN membership denial in 2005, AAFS training claim, and absence of accredited training documentation. His application was denied because he could not document attendance at an accredited polygraph training programme [3]Verified Is John Grogan, the 'Lie Detector Guy,' Scamming Everyone?
Confirms media coverage of Grogan credential concerns, Trisha Paytas testimony, Scott Cramer investigation, Paolella letter contents, and RHOC Season 19 appearance. The GPN subsequently listed him as a known fraudulent examiner on their official fraud profile page [19]Verified John Grogan Fraud Documentation — Global Polygraph Network
Confirms GPN investigation details, real-time results impossibility, question construction violations, and timeline discrepancies in Grogan's claims. GPN has publicly stated: avoid known fraudulent examiners, such as John Grogan [6]Verified Avoid Lie Detector Testing Fraud/Scams — Global Polygraph Network
Confirms GPN guidance on polygraph fraud avoidance, 90-95% accuracy range for properly conducted specific-issue testing, and consumer protection steps.
Following his GPN rejection, Grogan reportedly created his own organisation called 'Polygraph Examiners of America' [20]Verified GPN Fraud Profile — Polygraph Examiners of America
Confirms Grogan created Polygraph Examiners of America after being rejected for GPN membership. Creating one's own professional body after being rejected by legitimate organisations is a recognised red flag in polygraph advertising.
Ineligibility for APA and CAPE Membership
APA membership requires graduation from an APA-accredited school, adherence to professional standards, and ongoing continuing education [16]Verified Policy for APA Continuing Education Hours
Confirms APA requires practising examiners to complete minimum 30 continuing education hours every two years. The California Association of Polygraph Examiners (CAPE) similarly requires graduation from an APA-approved training school. Grogan does not meet the minimum requirements for membership in either organisation [1]Verified John Grogan Fraud Profile — Global Polygraph Network
Confirms GPN's investigation of Grogan including ACFS certificate details, GPN membership denial in 2005, AAFS training claim, and absence of accredited training documentation.

Confirms Trimarco served as head of FBI LA Polygraph Unit, trained at DoD Polygraph Institute, certified by APA/CAPE/AAPP, conducted 3,500+ examinations — publicly denounced Grogan as a fraud during a March 2008 call to the Tom Leykis Show, a Los Angeles radio programme [5]Verified Dr. Phil Replaces Jack Trimarco with John Grogan, Whom Trimarco Called 'a Fraud'
Confirms Trimarco's 2008 on-air denunciation of Grogan on the Tom Leykis Show, Grogan's 2009 defamation lawsuit, and Paolella's status as former Secret Service polygraph operator. Trimarco, who conducted over 3,500 polygraph examinations during his career, described Grogan as 'not a polygraph examiner' and 'nothing more than a fraud' [22]Verified Jack Trimarco — Nationally Recognised FBI Polygraph Examiner
Confirms Trimarco conducted 1,100+ polygraph examinations during FBI career, served FBI Los Angeles from 1978-1998, conducted 3,500+ total examinations. Grogan subsequently filed a defamation lawsuit against Trimarco, which was settled out of court in 2009 [23]Verified John Grogan Defamation Lawsuit — PC Gamer Coverage

Confirms GPN's investigation of Grogan including ACFS certificate details, GPN membership denial in 2005, AAFS training claim, and absence of accredited training documentation. While these appearances may seem impressive to viewers unfamiliar with the profession, they represent fundamental violations of polygraph testing protocols.
APA and ASTM Standards of Practice prohibit testing in front of a live audience, since a sterile, controlled environment is needed to minimise physiological interference [1]Verified John Grogan Fraud Profile — Global Polygraph Network
Confirms GPN's investigation of Grogan including ACFS certificate details, GPN membership denial in 2005, AAFS training claim, and absence of accredited training documentation. Legitimate polygraph testing requires multiple chart collections — at least three presentations of each relevant question must be recorded and analysed before any result can be determined [1]Verified John Grogan Fraud Profile — Global Polygraph Network
Confirms GPN's investigation of Grogan including ACFS certificate details, GPN membership denial in 2005, AAFS training claim, and absence of accredited training documentation. It is scientifically impossible to render a valid polygraph decision in real time based on a single presentation of a question.
Grogan's own website contains a revealing disclaimer about his television work, stating that some TV exams have 'scripted, predetermined, entertainment, or known solution results' [25]Verified Grogan Website TV Disclaimer
Confirms Grogan's website states some TV exams have 'scripted, predetermined, entertainment, or known solution results'. This admission confirms that his on-screen polygraph demonstrations often have nothing to do with genuine deception detection. Understanding how social media and viral clips spread polygraph misinformation is critical for consumers — see our analysis of TikTok polygraph trends for more.
The RHOC Season 19 Controversy
Grogan's appearance on The Real Housewives of Orange County Season 19 brought renewed scrutiny to his credentials [3]Verified Is John Grogan, the 'Lie Detector Guy,' Scamming Everyone?
Confirms media coverage of Grogan credential concerns, Trisha Paytas testimony, Scott Cramer investigation, Paolella letter contents, and RHOC Season 19 appearance. During the episode, cast members were given polygraph tests at Emily Simpson's party — notably in a closet, not in a controlled environment [26]Verified Why Katie Ginella Broke the Fourth Wall — Bravo
Confirms Katie described the polygraph as 'a random non-certified polygraphy test' conducted 'not in a controlled environment; in her closet'. Cast member Katie Ginella later called the entire setup into question, telling cameras: 'So that guy that they hired [for the test], you know he's a paid actor?' and pulling out a photo from Grogan's own website that advertised acting gigs [27]Verified Why John Grogan's RHOC Appearance Sparked Controversy
Confirms Katie's on-air accusation that Grogan was 'a paid actor' and showing photos from his website advertising acting gigs.
Katie later described the test conditions as a 'random non-certified polygraphy test' conducted 'not in a controlled environment; in her closet' [26]Verified Why Katie Ginella Broke the Fourth Wall — Bravo
Confirms Katie described the polygraph as 'a random non-certified polygraphy test' conducted 'not in a controlled environment; in her closet'. On Reddit, fans widely questioned the test's legitimacy, with one commenter noting that Grogan 'has pages dedicated to how much of an unqualified hack he is' [28]Verified Why RHOC's Katie Ginella Might Actually Be Telling the Truth
Confirms Reddit users widely questioned Grogan's qualifications following RHOC appearance, noting his lack of accredited credentials. The RHOC incident perfectly illustrates why consumers should never rely on entertainment-style polygraph demonstrations for any purpose with real-life consequences.
The Trisha Paytas Allegations
YouTube creator Scott Cramer produced a 23-minute investigation titled 'The Truth Behind The Lie Detector Guy' examining Grogan's credentials and practices [3]Verified Is John Grogan, the 'Lie Detector Guy,' Scamming Everyone?
Confirms media coverage of Grogan credential concerns, Trisha Paytas testimony, Scott Cramer investigation, Paolella letter contents, and RHOC Season 19 appearance. During this investigation, Cramer featured testimony from Trisha Paytas, who publicly stated that Grogan offered to provide whatever answer she wanted during testing, saying: 'I can give you whatever answer you want' and 'Tell me what you want me to say' [3]Verified Is John Grogan, the 'Lie Detector Guy,' Scamming Everyone?
Confirms media coverage of Grogan credential concerns, Trisha Paytas testimony, Scott Cramer investigation, Paolella letter contents, and RHOC Season 19 appearance. If true, this would represent a fundamental ethical violation — an examiner offering to fabricate results undermines the entire purpose of a polygraph examination.
This type of behaviour is precisely what consumers should watch out for. Our guide on polygraph examiners guaranteeing outcomes explains why any examiner who promises a specific result should be avoided. Similarly, our article on why polygraph guarantees are a red flag provides essential consumer protection information.
Phone-Based Lie Detection: A Scientific Impossibility
Voice Stress Analysis Is Not Lie Detection
Grogan has offered lie detection services over the phone via his website groganvsa.com as a less expensive alternative to polygraph testing [1]Verified John Grogan Fraud Profile — Global Polygraph Network
Confirms GPN's investigation of Grogan including ACFS certificate details, GPN membership denial in 2005, AAFS training claim, and absence of accredited training documentation. This offering is deeply problematic for two reasons: first, polygraph testing by definition requires physical sensors (pneumograph tubes, galvanic skin response sensors, and a blood pressure cuff) attached to the examinee's body. No meaningful physiological data can be collected remotely over a phone line.
Second, voice stress analysis (VSA) technology — which purports to detect deception through vocal patterns — has been thoroughly discredited by scientific research. An NIJ-funded field study found that VSA programmes' ability to accurately detect deception was approximately 50 percent — no better than a coin flip [29]Verified Voice Stress Analysis: Only 15 Percent of Lies Detected in Field Test
Confirms NIJ-funded study found VSA accuracy at approximately 50 percent — no better than chance — for detecting deception about drug use. The study concluded that VSA programmes were 'no better than flipping a coin when it comes to detecting deception' [29]Verified Voice Stress Analysis: Only 15 Percent of Lies Detected in Field Test
Confirms NIJ-funded study found VSA accuracy at approximately 50 percent — no better than chance — for detecting deception about drug use. The APA has stated that VSA devices have been 'discredited by a large and expanding body of independent scientific research' and are 'banned by the US Department of Defense' [30]Verified Review of Voice Stress Based Technologies
Confirms VSA devices are 'highly unreliable,' 'discredited by a large and expanding body of independent scientific research,' and 'banned by the US Department of Defense'. A separate government-funded evaluation by the Air Force Research Laboratory concluded that while VSA units may recognise stress, they could not be proven to detect deception [31]Verified Investigation and Evaluation of Voice Stress Analysis Technology
Confirms Air Force Research Laboratory evaluation concluded VSA units could not be proven to detect deception.
Offering phone-based lie detection as a genuine service exploits consumers who may not understand these limitations. For a detailed explanation of why VSA is not a legitimate deception detection tool, read our comprehensive guide on voice stress analysis: why it is not a lie detector.
Legal and Ethical Implications
California's Lack of Licensing Requirements
California does not require polygraph examiners to obtain a state licence [32]Verified State-by-State Breakdown of Polygraph Licensing Requirements
Confirms California does not require polygraph examiners to obtain a state licence. This regulatory gap means that, technically, anyone in California can claim to be a polygraph examiner and offer testing services to the public [33]Verified California Polygraph Examiner Requirements — J.J. Keller
Confirms California does not have state-level polygraph examiner requirements. However, this absence of state regulation does not make unqualified practice acceptable — it makes consumer vigilance even more essential.
Importantly, Grogan would not qualify for licensure in any US state that does require a polygraph licence [1]Verified John Grogan Fraud Profile — Global Polygraph Network
Confirms GPN's investigation of Grogan including ACFS certificate details, GPN membership denial in 2005, AAFS training claim, and absence of accredited training documentation. States like Texas, Virginia, and others require completion of a 400-hour APA-accredited training programme, supervised examination experience, background checks, and passage of state-administered licensing examinations [34]Verified State-by-State Guide to Polygraph Licensing
Confirms Texas requires 400-hour APA-accredited training programme, state examination, and supervised experience for polygraph licensure. California's lack of licensing is precisely what allows individuals without proper qualifications to operate, making it imperative that consumers independently verify credentials.
Research on investigative interviewing has demonstrated that even trained professionals can exhibit shortcomings in their practice [35]Verified The Investigation and Investigative Interviewing of Benefit Fraud Suspects in the UK
Research on investigative interviewing demonstrating that even trained professionals can exhibit shortcomings — reinforcing the importance of proper polygraph examiner training, reinforcing the importance of proper polygraph examiner training. When examiners lack any formal training whatsoever, the risks to consumers multiply dramatically. Read our California polygraph scam warning guide for state-specific advice.
The $145 Price Problem
Grogan advertises polygraph tests starting at $145 [2]Verified John Grogan Instagram Profile
Confirms Grogan's self-reported claims of 13,000+ persons tested, $145 pricing, 1000+ TV appearances, and 'since 1980s' claim. This pricing is itself a significant red flag. A properly conducted polygraph examination by a qualified, examiner trained to APA standards requires substantial time for pre-test interviews, multiple chart collections, data analysis using validated scoring algorithms, and post-test procedures. This process typically takes two to three hours of an expert's time, along with the overhead of maintaining professional equipment, continuing education, insurance, and office space.
When a polygraph test is priced dramatically below industry norms, consumers should ask themselves what corners are being cut. As the GPN fraud avoidance guide notes, modern polygraph techniques produce accuracy rates consistently within the 90 to 95 percent range for specific-issue testing — but only when the test is done correctly [6]Verified Avoid Lie Detector Testing Fraud/Scams — Global Polygraph Network
Confirms GPN guidance on polygraph fraud avoidance, 90-95% accuracy range for properly conducted specific-issue testing, and consumer protection steps. Our guide on polygraph prices that seem too good to be true explains the hidden costs of budget testing, while our article on cheap lie detector tests costing double details why underpaying for a polygraph often means paying twice.
How to Verify a Polygraph Examiner's Credentials
Step-by-Step Verification Process
Legitimate polygraph examiners have verifiable credentials that can be independently confirmed. After attending and graduating from an APA-accredited school, an examiner undergoes an internship — typically one year — before becoming certified by the training facility [6]Verified Avoid Lie Detector Testing Fraud/Scams — Global Polygraph Network
Confirms GPN guidance on polygraph fraud avoidance, 90-95% accuracy range for properly conducted specific-issue testing, and consumer protection steps. If the examiner works in a state that requires a polygraph licence, they must obtain that licence following the internship. They must then continue their education annually, with training approved by the APA [6]Verified Avoid Lie Detector Testing Fraud/Scams — Global Polygraph Network
Confirms GPN guidance on polygraph fraud avoidance, 90-95% accuracy range for properly conducted specific-issue testing, and consumer protection steps.
Consumers should take the following steps before hiring any polygraph examiner:
1. Ask for the examiner's APA membership number and verify it directly with the American Polygraph Association.
2. Request the name and dates of the APA-accredited training programme they attended, and cross-reference with the APA's official list of accredited programmes [13]Verified CIA Polygraph Examiner Requirements
Confirms APA-accredited programs require minimum 400 hours of in-residence study completed in 10-17 weeks with 95% instruction by recognised faculty.
3. Check whether the examiner holds state licensing where applicable, through the APA's state licensing boards directory.
4. Verify membership in professional organisations such as the APA, NPA, CAPE, or AAPP.
5. Ask about recent continuing education credits — APA requires 30 hours every two years [16]Verified Policy for APA Continuing Education Hours
Confirms APA requires practising examiners to complete minimum 30 continuing education hours every two years.
6. Enquire whether the examiner would be willing to have disputed results reviewed by an independent quality control examiner [6]Verified Avoid Lie Detector Testing Fraud/Scams — Global Polygraph Network
Confirms GPN guidance on polygraph fraud avoidance, 90-95% accuracy range for properly conducted specific-issue testing, and consumer protection steps.
If an examiner refuses to provide this information, treats verification requests as unreasonable, or becomes defensive, those are clear warning signs. For additional guidance, see our article on preventing intimidation during a lie detector exam.
Red Flags of Unqualified Polygraph Examiners
Warning Signs to Watch For
Based on the documented issues with Grogan's practice, consumers should be alert to the following red flags when evaluating any polygraph examiner:
Extremely low pricing that dramatically undercuts qualified examiners in the area. Grogan's $145 starting price is far below what examiners trained to APA standards typically charge for a properly conducted examination. Budget pricing often signals that proper procedures are being skipped.

Confirms APA requires practising examiners to complete minimum 30 continuing education hours every two years. Many examiners also belong to professional organisations such as the APA, NPA, or CAPE. Our PEAK CATC training overview details what a quality programme looks like.
What should I do if I've already been tested by an unqualified examiner?
If you have received a polygraph examination from someone whose credentials you now question, the results should not be relied upon for any important decision. Consider having the test re-administered by a qualified, examiner trained to APA standards who can conduct a proper examination following validated protocols. If the results of an unqualified test were used in legal proceedings, consult an attorney immediately. You can also request a quality control review of any existing examination charts by an independent professional examiner. Book a test with a verified professional through LieDetectorTest.com to get reliable results.
