Understanding the Employee Polygraph Protection Act

The Employee Polygraph Protection Act of 1988 (EPPA) is the single most important piece of legislation that HR professionals must understand before considering any credibility assessment tool for pre-employment screening. EPPA prohibits most private-sector employers from using "lie detector" tests for pre-employment screening or during the course of employment, with specific narrow exemptions [5]Verified Employment Law Guide - Lie Detector Tests
Confirms EPPA prohibits most private employers from using lie detector tests, government agencies are exempt, and details procedural requirements.

The Act's definition of "lie detector" is intentionally broad. Under 29 U.S.C. § 2001(3), a lie detector is defined as "a polygraph, deceptograph, voice stress analyzer, psychological stress evaluator, or any other similar device (whether mechanical or electrical) that is used, or the results of which are used, for the purpose of rendering a diagnostic opinion regarding the honesty or dishonesty of an individual" [6]Verified 29 U.S. Code § 2001 - Definitions
Confirms EPPA definition of 'lie detector' under 29 U.S.C. § 2001(3) including 'any other similar device' language. This "any other similar device" language is the crux of the legal debate surrounding EyeDetect.

The EPPA carries significant enforcement mechanisms. Civil penalties of up to $10,000 per violation may be assessed under 29 U.S.C. § 2005(a)(1) [7]Verified 29 USC Ch. 22: Employee Polygraph Protection - Enforcement Provisions
Confirms EPPA civil penalty maximum of $10,000 per violation under 29 U.S.C. § 2005(a)(1), 3-year statute of limitations, and private right of action for employees. Additionally, affected employees may pursue private civil actions for reinstatement, promotion, payment of lost wages and benefits, and reasonable attorney's fees [7]Verified 29 USC Ch. 22: Employee Polygraph Protection - Enforcement Provisions
Confirms EPPA civil penalty maximum of $10,000 per violation under 29 U.S.C. § 2005(a)(1), 3-year statute of limitations, and private right of action for employees. Actions must be commenced within 3 years of the alleged violation [7]Verified 29 USC Ch. 22: Employee Polygraph Protection - Enforcement Provisions
Confirms EPPA civil penalty maximum of $10,000 per violation under 29 U.S.C. § 2005(a)(1), 3-year statute of limitations, and private right of action for employees.

Does EyeDetect Fall Under EPPA?

This is the question that keeps employment lawyers busy and HR directors cautious. There are two competing perspectives:

The argument that EyeDetect IS covered by EPPA: The statute explicitly includes "any other similar device" used to render opinions about honesty [6]Verified 29 U.S. Code § 2001 - Definitions
Confirms EPPA definition of 'lie detector' under 29 U.S.C. § 2001(3) including 'any other similar device' language. EyeDetect unquestionably produces a diagnostic opinion about whether the subject is being truthful. The "similar device" language was specifically included to prevent employers from circumventing the law by switching to different technology that achieves the same end.

The argument that EyeDetect is NOT covered by EPPA: EPPA was drafted in the 1980s with specific technologies in mind. The statute explicitly names devices that measure physiological stress responses. EyeDetect measures cognitive load through ocular-motor behavior, a fundamentally different approach that does not attach sensors to the body or measure traditional physiological channels.

Notably, even Converus's own FAQ acknowledges that "although the EPPA law specifically mentions polygraph, the law has been applied in practice more broadly to the use of any lie detection solution" [8]Verified EyeDetect Frequently Asked Questions
Confirms Converus formed as CAT LLC in October 2009, renamed December 2013, and that EPPA 'has been applied in practice more broadly to the use of any lie detection solution'. This is why Converus developed EyeDetect+ in 2020, which adds a "Physio Tracker" device that gathers cardiovascular, respiration, and electrodermal data — the same physiological channels measured by a traditional polygraph [9]Verified New Version of EyeDetect Legally Compliant in All 50 States

The Practical Reality for HR Professionals

Until there is clear judicial precedent or Department of Labor guidance, HR professionals operating in the private sector should treat EyeDetect with the same caution they would apply to a polygraph for pre-employment purposes. The potential penalties for EPPA violations include civil penalties of up to $10,000 per violation [7]Verified 29 USC Ch. 22: Employee Polygraph Protection - Enforcement Provisions

A significant milestone occurred when a New Mexico judicial district court granted a Daubert motion allowing EyeDetect test results as evidence for the first time [10]Verified U.S. District Court Allows EyeDetect Lie Detector Test Results As Evidence for First Time
Confirms New Mexico court granted Daubert motion for EyeDetect evidence admissibility, marking first court acceptance of EyeDetect results. While this demonstrates growing judicial recognition of the technology's scientific foundation, it does not resolve the EPPA question for pre-employment screening purposes.

For most private-sector employers, the risk-reward calculation currently favors caution. However, for EPPA-exempt employers, EyeDetect and especially EyeDetect+ represent powerful tools that can dramatically streamline the credibility assessment process.

Who Can Legally Use Credibility Assessment in Hiring?

While EPPA restricts most private employers, several categories of employers are partially or fully exempt from the Act's prohibitions [5]Verified Employment Law Guide - Lie Detector Tests
Confirms EPPA prohibits most private employers from using lie detector tests, government agencies are exempt, and details procedural requirements. For these employers, EyeDetect represents a viable and highly efficient screening tool.

Fully Exempt — Federal, State & Local Government: Government agencies at all levels are exempt from EPPA [5]Verified Employment Law Guide - Lie Detector Tests

Confirms 12 peer-reviewed publications validating EyeDetect, 86-88% accuracy, 60 measurements per second, and over 600 customers worldwide as of 2024, at a fraction of the cost of a full polygraph examination. When agencies receive thousands of applications for positions requiring security clearances, EyeDetect provides an efficient first-pass screening layer. If you work in a government hiring capacity, understanding how professional polygraph services work will help you evaluate where EyeDetect fits within your existing credibility assessment framework.

However, it should be noted that DoD Directive 5210.91 and ODNI Security Agent Directive 2 currently prohibit the use of any credibility assessment solution other than polygraph for federal government purposes [11]Verified EyeDetect Marketer Converus Spends Hundreds of Thousands of Dollars Lobbying Federal Agencies
Confirms Converus lobbying efforts, lack of independent peer-reviewed validation, 500 customers in 40 countries, US Embassy deployments, and skepticism from advisory board member and independent researchers, which limits direct federal adoption until these regulations are updated.

Private Security and Pharmaceutical Companies

Security firms that fall within EPPA's security service exemption are another key industry for EyeDetect. Converus specifically developed EyeDetect+ with this market in mind, noting it meets the EPPA definition of polygraph to allow pre-screening of "prospective employees of armored car, security alarm, and security guard firms who protect facilities, materials or operations" [10]Verified U.S. District Court Allows EyeDetect Lie Detector Test Results As Evidence for First Time
Confirms New Mexico court granted Daubert motion for EyeDetect evidence admissibility, marking first court acceptance of EyeDetect results.

For pharmaceutical manufacturers, distributors, and dispensaries with DEA authorization, EyeDetect could serve as an efficient screening layer for positions in drug manufacturing plants, distribution warehouses, and research laboratories where controlled substances are present. The relatively low cost per test makes it economically viable even for large-scale hiring campaigns.

Even exempt employers must follow EPPA's procedural requirements when using credibility assessment. The exemption does not give blanket permission — it requires that the position involve protective or drug-access functions and that the employer follows specific notice and documentation requirements [5]Verified Employment Law Guide - Lie Detector Tests
Confirms EPPA prohibits most private employers from using lie detector tests, government agencies are exempt, and details procedural requirements.

When to Use Each Tool

The most effective approach for many organizations is a layered strategy that leverages the strengths of each tool:

EyeDetect as first-pass screening: Use EyeDetect to efficiently process large applicant pools at the early stages of hiring. Its speed and low cost make it ideal for triaging hundreds or thousands of candidates. Research on screening polygraph formats has shown that different analytical methods produce meaningfully different accuracy rates [14]Verified An Exploration of Methods for the Analysis of Multiple-Issue Relevant/Irrelevant Screening Data
Demonstrates that different scoring and analytical methods produce meaningfully different accuracy rates in screening tests, supporting the value of automated algorithmic scoring, making automated scoring a significant advantage.

Polygraph as in-depth assessment: Reserve full polygraph examinations for candidates who have passed initial screening stages. The depth and rigor of a professionally administered polygraph, including the valuable pre-test interview, provides a more comprehensive assessment. Studies have demonstrated that polygraph tests yield substantial improvements in information gain over unassisted human judgment across nearly the complete range of base rates [15]Verified Information gain of psychophysiological detection of deception in forensic and screening settings
Demonstrates polygraph tests provide substantial information gain over unassisted human judgment across nearly the complete range of base rates.

Dual-testing for critical positions: For the most sensitive positions — particularly those involving national security, classified information, or access to dangerous materials — using both EyeDetect and polygraph provides the strongest credibility assessment framework. This paired approach is similar to principles discussed in our guide on paired testing examinations.

Converus itself positions EyeDetect as a companion to traditional polygraph rather than a replacement. As their own materials state, it is "a viable companion to traditional polygraph tests as a pre-screening tool or alternative when examinees are unsuitable for polygraph" [2]Verified 12th Peer-Reviewed Publication Further Validates Eye Behavior as an Accurate Deception Detection Method

Laboratory vs. field conditions: Many accuracy studies are conducted under controlled laboratory conditions where participants are instructed to lie about specific things. Real-world pre-employment screening occurs under different psychological conditions. Converus's CEO has acknowledged this gap, noting confidence that "when EyeDetect's accuracy is measured using real criminals, as opposed to a mock crime, the accuracy will be in the 90th percentile" [16]Verified New Study Shows Accuracy of EyeDetect Remains Unchanged Between English and Spanish-Speaking Participants
Confirms EyeDetect accuracy of approximately 85% across English and Spanish-speaking populations in peer-reviewed study in International Journal of Applied Psychology.

Base rate effects: In pre-employment screening, the vast majority of applicants are likely telling the truth about most topics. When the base rate of deception is low, even a test with high accuracy will produce false positives relative to true positives. Dr. Kircher himself has acknowledged this: "Even if a test is 90 percent accurate, about 10 percent of the tested population would fail it, and the vast majority of those individuals who fail the test would be innocent" [11]Verified EyeDetect Marketer Converus Spends Hundreds of Thousands of Dollars Lobbying Federal Agencies

These considerations apply equally to traditional polygraph testing. Security screening polygraph research has shown asymmetric accuracy patterns — for example, one study found 94.9% accuracy for innocent examinees but only 43.2% for guilty examinees [17]Verified Studies of the accuracy of security screening polygraph examinations

Confirms the NAS 2003 report title, scope of review covering polygraph accuracy, screening uses, and alternatives, and APA's claimed 80-98% accuracy range. However, the NAS itself found that the evidence was limited and that "specific-incident polygraph tests can discriminate lying from truth telling at rates well above chance, though well below perfection" [19]Verified Polygraph - Wikipedia (NAS Findings)
Confirms NAS found specific-incident polygraph tests 'can discriminate lying from truth telling at rates well above chance, though well below perfection' and that screening accuracy is lower.

When comparing EyeDetect and polygraph accuracy, several factors complicate direct comparison: polygraph accuracy depends heavily on the skill of the examiner while EyeDetect scoring is fully automated [3]Verified EyeDetect FAQs
Confirms EyeDetect measurement variables (pupil dilation, response accuracy, response time, gaze fixation, blink rates, reading behavior), Converus Credibility Score methodology, and 10 peer-reviewed research articles; polygraph includes an extensive pre-test interview that may itself reveal important information; and the two technologies measure different phenomena using different methodologies.

For HR professionals, the bottom line is that neither technology is infallible. Any credibility assessment tool should be used as one input among many in a comprehensive hiring decision — never as the sole determinant. Understanding other comparison technologies can be helpful — see our analysis of facial recognition vs. polygraph for lie detection.

State Biometric Privacy Laws

Beyond EPPA, employers using EyeDetect must navigate a growing patchwork of state biometric privacy laws. Eye-tracking data may qualify as protected biometric information under several state statutes:

Illinois BIPA (Biometric Information Privacy Act): Enacted in 2008, BIPA is the most stringent biometric privacy law in the nation [21]Verified Biometric Information Privacy Act (BIPA) - Wikipedia
Confirms Illinois BIPA enacted 2008, private right of action, $1,000/$5,000 per violation damages, and that it is the most stringent biometric privacy law in the U.S..

Additional states: Washington State's biometric privacy law (Code 19.375.020) and comprehensive consumer privacy laws in California, Colorado, Connecticut, Utah, and Virginia also expressly govern the processing of biometric information [21]Verified Biometric Information Privacy Act (BIPA) - Wikipedia
Confirms Illinois BIPA enacted 2008, private right of action, $1,000/$5,000 per violation damages, and that it is the most stringent biometric privacy law in the U.S..

Employers should consult legal counsel to determine whether eye-tracking data collected by EyeDetect constitutes a "biometric identifier" under these various state laws. The safest approach is to treat eye-tracking data as protected biometric information and implement appropriate consent and data handling protocols.

ADA and Discrimination Considerations

Employers must also consider whether EyeDetect screening could implicate the Americans with Disabilities Act (ADA). If the test could be interpreted as a medical examination under the ADA, it may be subject to restrictions on when it can be administered during the hiring process.

Additionally, employers should monitor for any disparate impact that EyeDetect screening may have on protected classes. While the automated scoring eliminates examiner bias — a frequently cited advantage [2]Verified 12th Peer-Reviewed Publication Further Validates Eye Behavior as an Accurate Deception Detection Method
Confirms 12 peer-reviewed publications validating EyeDetect, 86-88% accuracy, 60 measurements per second, and over 600 customers worldwide as of 2024 — the underlying algorithm itself could potentially produce different error rates across demographic groups. HR professionals should track outcomes data and conduct periodic adverse impact analyses.

For organizations navigating the intersection of credibility assessment and compliance requirements, understanding federal frameworks like the PCSOT and Adam Walsh Act requirements provides important regulatory context.

Direct Cost Comparison

The cost advantage of EyeDetect over traditional polygraph is substantial, particularly for high-volume screening programs:

EyeDetect per-test cost: $25-$75, depending on volume and service provider. The low cost is driven by automated scoring that eliminates the need for a licensed polygraph examiner. One proctor operating three stations can administer up to 30 tests daily [2]Verified 12th Peer-Reviewed Publication Further Validates Eye Behavior as an Accurate Deception Detection Method
Confirms 12 peer-reviewed publications validating EyeDetect, 86-88% accuracy, 60 measurements per second, and over 600 customers worldwide as of 2024.

Traditional polygraph per-test cost: $200-$800, reflecting the expertise of the licensed examiner, the 90+ minute session duration, and individualized assessment. Most polygraph examiners conduct only 2-3 exams per day [2]Verified 12th Peer-Reviewed Publication Further Validates Eye Behavior as an Accurate Deception Detection Method
Confirms 12 peer-reviewed publications validating EyeDetect, 86-88% accuracy, 60 measurements per second, and over 600 customers worldwide as of 2024.

For an agency screening 1,000 applicants annually, the difference is dramatic: approximately $25,000-$75,000 for EyeDetect versus $200,000-$800,000 for full polygraph examinations. This cost differential makes EyeDetect especially attractive as a pre-screening layer that narrows the applicant pool before investing in full polygraph examinations for final candidates.

Infrastructure and Operational Costs

Beyond per-test costs, organizations should consider the total cost of ownership:

Equipment: EyeDetect stations consist of a computer with a high-definition eye-tracking camera. Multiple stations can be operated by a single proctor, scaling throughput efficiently.

Training: EyeDetect proctors can be trained and certified in a matter of hours [2]Verified 12th Peer-Reviewed Publication Further Validates Eye Behavior as an Accurate Deception Detection Method
Confirms 12 peer-reviewed publications validating EyeDetect, 86-88% accuracy, 60 measurements per second, and over 600 customers worldwide as of 2024, compared to the months of specialized training required for polygraph examiners. For information on polygraph examiner certification requirements, see our polygraph training page.

Facilities: EyeDetect requires only a quiet room with a desk — no specialized examination suite is needed. The non-contact nature of the test also means it supports safe social distancing protocols [9]Verified New Version of EyeDetect Legally Compliant in All 50 States
Confirms EyeDetect+ development with Physio Tracker to meet polygraph definition, compliance in all 50 states, 500+ customers in 43 countries as of 2020.

The Candidate Perspective

EyeDetect offers a notably different candidate experience compared to traditional polygraph:

No physical contact: No sensors are attached to the body [2]Verified 12th Peer-Reviewed Publication Further Validates Eye Behavior as an Accurate Deception Detection Method
Confirms 12 peer-reviewed publications validating EyeDetect, 86-88% accuracy, 60 measurements per second, and over 600 customers worldwide as of 2024. The candidate simply sits at a desk and looks at a computer screen. This non-invasive approach is generally well-received by candidates and eliminates the discomfort associated with blood pressure cuffs, pneumograph tubes, and electrodermal sensors.

Shorter duration: At 15-30 minutes, EyeDetect tests are significantly shorter than the 90+ minute traditional polygraph examination [2]Verified 12th Peer-Reviewed Publication Further Validates Eye Behavior as an Accurate Deception Detection Method
Confirms 12 peer-reviewed publications validating EyeDetect, 86-88% accuracy, 60 measurements per second, and over 600 customers worldwide as of 2024. This reduces candidate fatigue and scheduling burden.

No examiner interaction: The test is fully automated [3]Verified EyeDetect FAQs
Confirms EyeDetect measurement variables (pupil dilation, response accuracy, response time, gaze fixation, blink rates, reading behavior), Converus Credibility Score methodology, and 10 peer-reviewed research articles, which eliminates the anxiety some candidates feel during the interpersonal dynamics of a polygraph examination. It also means every candidate receives an identical testing experience, which strengthens claims of fairness and consistency.

However, organizations should be transparent with candidates about what the test involves, how results will be used, and what data will be collected. This is not only good practice — it may be legally required under various biometric privacy laws.

Consent and Data Protection Protocols

For organizations implementing EyeDetect, robust consent and data protection protocols are essential:

Obtain explicit written consent before administering any EyeDetect test, clearly explaining what biometric data will be collected, how it will be used, and when it will be destroyed.

Develop a biometric data retention and destruction policy that complies with the most restrictive applicable state law. Under Texas CUBI, biometric data collected for employer security purposes must be destroyed within a reasonable time after termination of the employment relationship [22]Verified Texas Capture or Use of Biometric Identifier Act
Confirms Texas CUBI definition of biometric identifiers, consent requirements, and that the Texas Attorney General has exclusive enforcement authority with up to $25,000 per violation penalties.

Ensure that test results and underlying biometric data are stored securely and access is limited to authorized personnel. Under EPPA, employers have strict duties of confidentiality regarding test results [5]Verified Employment Law Guide - Lie Detector Tests
Confirms EPPA prohibits most private employers from using lie detector tests, government agencies are exempt, and details procedural requirements.

Document that hiring decisions are never based solely on EyeDetect results but incorporate multiple assessment factors. This protects against both EPPA claims and general employment discrimination challenges.

Understanding the potential for countermeasures and test contamination is also important. Some substances and conditions can affect test reliability — our article on whether Xanax can affect lie detector tests explores related pharmacological considerations.

Implementation Recommendations

For organizations in exempt industries that have determined EyeDetect is legally appropriate:

1. Engage employment law counsel before any implementation. Review your EPPA exemption status, state-specific lie detector laws, biometric privacy laws (BIPA, CUBI, etc.), and any applicable union or collective bargaining agreements.

2. Define a clear testing policy that specifies which positions require screening, at what stage of hiring it will be administered, and precisely how results will factor into hiring decisions.

3. Use EyeDetect as one component of a layered screening process — not as a standalone pass/fail gate. Combine it with background checks, reference verification, structured interviews, and where appropriate, full polygraph examinations for final candidates.

4. Train all HR staff involved in the screening process on proper protocols, candidate communication, and data handling requirements.

5. Conduct regular adverse impact analyses to monitor whether EyeDetect screening produces disparate outcomes for any protected demographic group.

6. Maintain thorough documentation of every screening, including the legal basis for testing, consent forms, test results, and the complete set of factors considered in each hiring decision.

For organizations wanting to maximize the effectiveness of their credibility assessment program, understanding how polygraph and EyeDetect can work together is critical.
