Given the extraordinary sensitivity of DEA operations — which routinely involve classified intelligence, confidential informants, undercover operations, and coordination with foreign governments — the agency's personnel security program is among the most rigorous in the federal government. The polygraph examination serves as a cornerstone of this security apparatus, ensuring that every person granted access to DEA operations is trustworthy, honest, and free from vulnerabilities that could be exploited by criminal organizations or hostile intelligence services. For a broader overview, see our guide on public sector polygraph testing.

Why the DEA Relies on Polygraph Testing

DEA agents regularly interact with high-value targets, handle large quantities of seized narcotics and cash, manage confidential informant networks, and possess knowledge that — if leaked — could endanger lives and compromise years of investigative work. The agency's polygraph program serves multiple critical functions:

Pre-employment screening identifies applicants who may have undisclosed criminal histories, substance abuse problems, or connections to criminal organizations before they are granted access to sensitive operations. Counterintelligence protection detects potential foreign intelligence threats, including individuals who may have been recruited by or are sympathetic to foreign intelligence services or transnational criminal organizations. Ongoing integrity verification ensures that current employees continue to meet the agency's high standards of conduct.

The DEA's polygraph program operates under the authority of the Department of Justice (DOJ) and follows federal polygraph standards established by the National Center for Credibility Assessment (NCCA) [5]Verified DOJ OIG Management Advisory Memorandum - DEA Polygraph (Report 23-095)

Confirms age requirement (21-36), Top Secret clearance requirement, and 16-20 week Basic Agent Training at Quantico. In accordance with Public Law 100-238, the position is covered under law enforcement retirement provisions, meaning candidates must be appointed before reaching their 37th birthday unless they qualify for an exception as a preference-eligible veteran or have prior Federal civilian law enforcement service [17]Verified DEA Special Agent Job Announcement BA2022-3
Confirms age requirement not older than 36 at appointment, Top Secret clearance, and Lautenberg Act disqualification for domestic violence. These are firm requirements — maximum entry age exemption requests will not be granted for non-veteran preference eligible applicants who apply after their 35th birthday [17]Verified DEA Special Agent Job Announcement BA2022-3
Confirms age requirement not older than 36 at appointment, Top Secret clearance, and Lautenberg Act disqualification for domestic violence.

For positions beyond Special Agent — including Intelligence Research Specialists, Diversion Investigators, and Forensic Chemists — the DEA's polygraph program also applies. The Office of Personnel Management (OPM) approved the DEA's use of polygraph examinations for Special Agent positions in November 1994, for Intelligence Research Specialist positions in June 1998, and later expanded to additional positions [5]Verified DOJ OIG Management Advisory Memorandum - DEA Polygraph (Report 23-095)
Confirms DEA participates in NCCA Quality Assurance Program, 2019 policy change, and OIG finding that 77+ applicants were hired despite failing polygraph. Any position requiring a Top Secret security clearance will require polygraph testing. To understand how this compares to other agencies, see our CI Polygraph vs. Full Scope comparison guide.

The LEPET Format and Full-Scope Testing

The DEA administers a full-scope polygraph examination, which is the most comprehensive type of federal polygraph test available. According to NCCA documentation, the DEA uses the Law Enforcement Pre-Employment Test (LEPET) format, which is the standard screening technique used by federal law enforcement agencies including the FBI, DEA, ATF, and U.S. Secret Service [2]Verified NCCA Law Enforcement Pre-Employment Test (LEPET) Documentation
Confirms the DEA uses the LEPET format for pre-employment polygraph screening, along with FBI, ATF, and Secret Service.

The LEPET is a multi-phase examination. Applicants are given both a Suitability polygraph and a National Security polygraph examination that include questions related to past drug use, serious criminal activity, truthfulness on pre-employment documentation, and national security issues [5]Verified DOJ OIG Management Advisory Memorandum - DEA Polygraph (Report 23-095)
Confirms DEA participates in NCCA Quality Assurance Program, 2019 policy change, and OIG finding that 77+ applicants were hired despite failing polygraph. This two-phase approach effectively makes the DEA polygraph a full-scope examination combining counterintelligence and lifestyle/suitability elements.

Under federal IC policy, there are three types of polygraph examinations used for personnel security vetting: the Counterintelligence Scope Polygraph (CSP), the Expanded Scope Polygraph (ESP, also called Full-Scope), and the Specific Issue Polygraph (SIP) [18]Verified Security Executive Agent Directive 2 (Revised)
Defines CSP, ESP (Full-Scope), and SIP polygraph types; establishes NCCA as primary authority for federal polygraph standards. The ESP includes all CI topics plus criminal conduct, drug involvement, and falsification of security questionnaires [18]Verified Security Executive Agent Directive 2 (Revised)
Defines CSP, ESP (Full-Scope), and SIP polygraph types; establishes NCCA as primary authority for federal polygraph standards. The DEA's approach aligns with the ESP/full-scope model. Learn more about the Federal Zone Comparison Test (FZCT) and the Law Enforcement Pre-Employment Test (LEPET).

The Three Phases of the DEA Polygraph

Every DEA polygraph examination consists of three distinct phases, each serving a specific purpose.

Phase 1: Pre-Test Interview (60-90 minutes) — The pre-test phase is often the longest and most significant portion of the examination. The examiner explains the polygraph process, reviews the candidate's background information and SF-86 security questionnaire, and discusses each question that will be asked during the in-test phase. No question is asked "cold" — every question is reviewed beforehand. The LEPET technique uses a structured format in which all test questions are reviewed with the examinee during the pre-test phase [2]Verified NCCA Law Enforcement Pre-Employment Test (LEPET) Documentation
Confirms the DEA uses the LEPET format for pre-employment polygraph screening, along with FBI, ATF, and Secret Service. Many significant admissions occur during this interview rather than during chart collection. Research has shown that the pre-test discussion of comparison questions between list repetitions significantly improves test accuracy [12]Verified The Discussion of Comparison Questions Between List Repetitions Is Associated with Increased Test Accuracy
Demonstrated that between-chart discussion of comparison questions significantly improved CQT accuracy, and proper question review before testing is a critical procedural component.

Phase 2: In-Test Data Collection (60-90 minutes) — The candidate is connected to the polygraph instrument, which monitors multiple physiological channels simultaneously. Modern instruments record thoracic and abdominal respiration via pneumograph components, electrodermal activity through finger plates, cardiovascular activity via blood pressure cuff, and movement through motion sensors. The examiner conducts multiple chart series — typically 3 to 5 presentations of the question sequence. Peer-reviewed research has demonstrated that comparison questions produce reliably different physiological patterns in innocent versus deceptive subjects [11]Verified The Role of Comparison Questions in Physiological Detection of Deception
Mock crime study with 120 participants demonstrating comparison questions produce different physiological patterns for innocent vs. guilty subjects, and that both directed-lie and probable-lie comparison formats produce valid results [19]Verified Directed Lie Comparison Questions in Polygraph Testing
Found directed-lie comparison produced fewer false positives while maintaining detection of deception[20]Verified Examining Different Types of Comparison Questions in a Field Study of CQT Polygraph Technique
Field study providing evidence for practical effectiveness of both exclusive and non-exclusive comparison questions.

Phase 3: Post-Test Review (15-30 minutes) — After collecting sufficient data, the examiner reviews the physiological recordings using validated numerical scoring algorithms. If there are indications of significant reactions, the examiner may conduct a post-test interview and additional chart series to clarify results.

Scoring Methodology and Outcomes

DEA polygraph charts are scored using validated numerical scoring systems. The federal government most commonly uses a seven-position scale (-3, -2, -1, 0, +1, +2, +3) [2]Verified NCCA Law Enforcement Pre-Employment Test (LEPET) Documentation
Confirms the DEA uses the LEPET format for pre-employment polygraph screening, along with FBI, ATF, and Secret Service. There are four possible outcomes of a DEA polygraph examination:

No Significant Response (NSR) — The physiological data does not suggest deception. The candidate passes and proceeds to the next phase.

Significant Response (SR) — The data suggests deception on one or more relevant questions. This results in disqualification for a period of three years from the date of the examination [3]Verified DEA Special Agent Test Preparation Guide
Confirms polygraph disqualification periods: 3 years for SR/CM results, 2 years for three NO results.

Countermeasures (CM) — The examiner detects deliberate attempts to manipulate the test. This also results in a three-year disqualification [3]Verified DEA Special Agent Test Preparation Guide
Confirms polygraph disqualification periods: 3 years for SR/CM results, 2 years for three NO results.

No Opinion (NO) — The data is insufficient or ambiguous. A retest may be offered, but three consecutive No Opinion results will disqualify the applicant for a period of two years [3]Verified DEA Special Agent Test Preparation Guide
Confirms polygraph disqualification periods: 3 years for SR/CM results, 2 years for three NO results.

Research into scoring approaches, including Bayesian methods applied to polygraph data interpretation [21]Verified Comparison of Bayesian and Regression Approaches to the Study of Information Processing in Judgment
Foundational work on statistical decision models that influenced later development of Bayesian approaches to polygraph data interpretation, has contributed to the development of more refined and reliable numerical scoring algorithms used in modern federal testing. Studies have also shown that directed-lie comparison questions may offer better resistance to countermeasure attempts [22]Verified Directed Lie Comparison Questions and Countermeasure Resistance
Research suggests directed-lie comparison questions may offer better countermeasure resistance, further supporting the reliability of properly administered examinations.

How DEA Polygraph Questions Are Structured

The DEA polygraph examination covers multiple topic areas, each designed to assess specific aspects of a candidate's honesty, integrity, and suitability for federal law enforcement service. All questions are reviewed with the candidate during the pre-test interview before any data is collected. The questions below represent the types and themes that may appear — actual question wording is proprietary and varies between examinations.

Research on question construction has shown that the formulation of test questions significantly impacts examination validity. Studies have identified critical problems in test question construction and emphasized that questions cannot be applied in a template-based fashion, requiring careful individualized preparation [23]Verified Problems of Questions in Event Knowledge Tests
Identified critical problems in test question construction emphasizing that tests cannot be applied in template-based fashion. Similarly, field studies comparing exclusive and non-exclusive comparison question formats have demonstrated that both approaches produce comparable accuracy rates [24]Verified Exclusive or Nonexclusive Comparison Questions: A Comparative Field Study
Israeli field study finding both exclusive and non-exclusive comparison question formats produced comparable accuracy rates[25]Verified Effectiveness of Control Questions Answered 'Yes'
Found no significant accuracy difference between yes and no answers to control questions, dispelling a widely held examiner belief.

Category 1: Personal History & Application Integrity

These questions assess whether the candidate has been truthful throughout the application process and in their personal documentation. Examples include whether the candidate has deliberately falsified any information on their DEA application, resume, or SF-86 security questionnaire; whether they have used a false identity or fraudulent documents; and whether they have intentionally concealed any aspect of their personal history they believed would be disqualifying.

These questions are fundamental because the entire DEA security process depends on the accuracy of candidate-provided information. Falsifying an SF-86 (Standard Form 86 — Questionnaire for National Security Positions) is a federal crime under 18 U.S.C. § 1001, punishable by up to five years in prison. A candidate will be found unsuitable for employment and automatically disqualified if they deliberately misrepresent their history in connection with their application for employment [4]Verified DEA Special Agent FAQs
Confirms DEA drug use policy updated June 27, 2024, including 3-year marijuana and 7-year other substance look-back periods.

Category 2: Criminal Conduct

Criminal history questions probe for undetected or unreported criminal behavior. These may cover whether the candidate has committed a serious crime for which they were not arrested, involvement in drug trafficking or manufacturing, participation in undisclosed criminal activity, acts of violence or domestic violence not reported to law enforcement, or membership in criminal organizations.

The DEA is particularly focused on detecting candidates with undisclosed criminal histories. Title 18 USC, Section 922(G) automatically disqualifies anyone convicted of a misdemeanor crime of domestic violence from appointment as a DEA Special Agent [17]Verified DEA Special Agent Job Announcement BA2022-3
Confirms age requirement not older than 36 at appointment, Top Secret clearance, and Lautenberg Act disqualification for domestic violence. Applicants must not have been convicted of any felony crime [17]Verified DEA Special Agent Job Announcement BA2022-3
Confirms age requirement not older than 36 at appointment, Top Secret clearance, and Lautenberg Act disqualification for domestic violence.

Category 3: Drug Use & Substance Abuse

Given the DEA's core mission of drug enforcement, substance use questions are among the most heavily scrutinized. These cover undisclosed illegal drug use, use of prescription medications without a valid prescription, involvement in drug sales or distribution, drug use since submitting the DEA application, and drug use while employed in law enforcement.

The DEA updated its pre-employment drug policy on June 27, 2024 [4]Verified DEA Special Agent FAQs
Confirms DEA drug use policy updated June 27, 2024, including 3-year marijuana and 7-year other substance look-back periods.

Confirms DEA drug use policy updated June 27, 2024, including 3-year marijuana and 7-year other substance look-back periods. The DEA's relatively firm stance on personal drug use contrasts with those of the CIA and FBI, which in 2023 considered further relaxing their eligibility guidelines to combat dwindling recruitment [8]Verified Drug Enforcement Administration - Wikipedia (Staffing Data)
Confirms 9,848 employees as of 2021 including 4,649 special agents and 5,199 support staff.

Category 4: Financial History & Integrity

Financial vulnerability questions assess susceptibility to bribery or corruption. These may cover involvement in fraudulent financial activities including tax evasion or embezzlement, receipt of money or favors in exchange for confidential information, undisclosed financial difficulties that could be used as leverage, and fraudulent insurance claims or tax returns.

Financial vulnerability is one of the primary vectors through which law enforcement officers are compromised. The DEA's international operations, involving coordination with governments and organizations worldwide, make financial integrity screening particularly critical.

Category 5: Professional Conduct & Ethics

These questions evaluate the candidate's professional integrity: deliberate lying to supervisors or HR professionals, undocumented unethical behavior at previous jobs, unauthorized disclosure of sensitive or classified information, and concealed terminations or disciplinary actions.

DEA applicants must possess and maintain the highest levels of character and conduct [14]Verified DEA Special Agent Job Announcement
Confirms age requirement (21-36), Top Secret clearance requirement, and 16-20 week Basic Agent Training at Quantico. An unfavorable decision in any area of the hiring process is deemed disqualifying [14]Verified DEA Special Agent Job Announcement
Confirms age requirement (21-36), Top Secret clearance requirement, and 16-20 week Basic Agent Training at Quantico.

Category 6: Counterintelligence & National Security

As a full-scope examination, the DEA polygraph includes significant counterintelligence content. Questions may address whether the candidate has been approached or recruited by any foreign intelligence service, provided classified information to unauthorized persons, has unreported contacts with foreign nationals, or engaged in activities that could be considered espionage, sabotage, or threats to U.S. national security.

The counterintelligence component is particularly significant because the DEA's intelligence unit is a member of the U.S. Intelligence Community [1]Verified Drug Enforcement Administration - Wikipedia
Confirms DEA is under DOJ, has approximately 4,649 special agents, is part of the Intelligence Community, and updated drug policy in June 2024. The DEA's international operations place personnel in regular contact with foreign officials and intelligence services. As part of the IC, the DEA must abide by the Office of the Director of National Intelligence's Security Executive Agent Directives (SEAD), including SEAD 2 which outlines the use of polygraph examinations for personnel security determinations [5]Verified DOJ OIG Management Advisory Memorandum - DEA Polygraph (Report 23-095)
Confirms DEA participates in NCCA Quality Assurance Program, 2019 policy change, and OIG finding that 77+ applicants were hired despite failing polygraph. For detailed information on CI-focused testing, see our Counterintelligence Scope Polygraph guide. Historical cases like the Jonathan Pollard intelligence failure demonstrate why counterintelligence screening remains critical for agencies with access to classified material.

Categories 7 & 8: Security Compliance, Associations & Additional Integrity

The remaining categories assess associations with individuals involved in criminal activities, awareness of unreported policy violations, intentional violations of federal regulations, and concealment of security-relevant information. A final set of integrity questions covers cheating on examinations, lying about credentials, vulnerability to blackmail, and any other undisclosed behaviors that could impact duty performance.

The final "catch-all" question gives candidates the opportunity to disclose anything they may have omitted. Experienced examiners understand that candidates sometimes hold back information until directly prompted. Full disclosure during the pre-test interview is always the recommended approach.

Before the Examination

Preparation for the DEA polygraph should begin well before your appointment date. Review your SF-86 thoroughly — every detail matters. Recall all relevant life events honestly, including any past drug use, legal issues, or foreign contacts. Get a full night of sleep before your exam and maintain your normal routine. Take your prescribed medications as directed by your physician.

Do not research countermeasures or techniques to manipulate the test. The NCCA's administration guides include specific countermeasures statements warning examinees that deliberate efforts to influence testing will adversely affect the process. The DEA considers such activity as evidence of non-cooperation. For more on why countermeasures are ineffective and counterproductive, see our guide: Can You Beat a Polygraph Test? 12 Myths vs. Scientific Facts.

During the Examination

The examination typically lasts 2-4 hours. You will be asked to sign a consent form before the examination begins. The examiner will explain the process, review all questions with you, and attach the polygraph components: two pneumograph tubes (chest and abdomen), electrodermal finger plates, a cardiovascular blood pressure cuff, and a motion sensor.

During chart collection, remain still, breathe normally, and answer questions with simple "yes" or "no" responses. The same questions will be repeated across multiple chart series. This repetition is essential for establishing consistent physiological patterns that can be reliably scored. Brief breaks are taken between chart series.

If the examiner identifies significant reactions during post-test review, you may be asked additional questions or complete additional chart series. This is normal procedure and does not necessarily indicate a problem. Research has shown that the concealed information detection paradigm can identify automatic retrieval processes related to crime-relevant information [26]Verified Guilty on the Go: Uncovering Concealed Information
Demonstrated paradigm detecting familiarity effects and response preparation processes in guilty participants, underscoring the scientific basis of physiological response measurement.

Some applicants who fail a CBP polygraph have subsequently passed polygraphs at the FBI or Secret Service [27]Verified CBP Polygraph Failure - ClearanceJobs Discussion
Confirms CBP 60% failure rate reputation and that other agencies may request application status but results do not preclude future hiring. Each agency makes its own independent adjudication. However, disclosing a prior polygraph failure is typically required on future security clearance applications, and attempting to conceal it would constitute falsification.

Key Findings from the 2023-2024 OIG Investigation

In August 2022, the DOJ Office of the Inspector General initiated an audit of the DEA's use of polygraph examinations in pre-employment vetting [5]Verified DOJ OIG Management Advisory Memorandum - DEA Polygraph (Report 23-095)
Confirms DEA participates in NCCA Quality Assurance Program, 2019 policy change, and OIG finding that 77+ applicants were hired despite failing polygraph. The findings, published in a Management Advisory Memorandum (Report 23-095), revealed several concerns that candidates should be aware of.

Prior to March 2019, DEA policy did not prohibit hiring applicants with Significant Response results — the DEA was the only federal law enforcement agency in the NCCA Quality Assurance Program that allowed this [5]Verified DOJ OIG Management Advisory Memorandum - DEA Polygraph (Report 23-095)

A follow-up audit (Report 24-114) was published in September 2024, examining the DEA's use of polygraphs in both pre-employment and foreign vetting processes [28]Verified DOJ OIG Audit of DEA Polygraph Use (Report 24-114)
Full audit of DEA polygraph program in pre-employment and foreign vetting processes published September 2024. These audits demonstrate that the DEA's polygraph program is subject to robust federal oversight and continuous improvement.

How the DEA Compares to FBI, CBP, and Other Agencies

Understanding how the DEA polygraph compares to other federal agencies helps candidates gauge the examination they will face. The DEA uses the Law Enforcement Pre-Employment Test (LEPET) format, which is the same format used by the FBI, ATF, and U.S. Secret Service for pre-employment screening [2]Verified NCCA Law Enforcement Pre-Employment Test (LEPET) Documentation
Confirms the DEA uses the LEPET format for pre-employment polygraph screening, along with FBI, ATF, and Secret Service. This means candidates who have previously taken a polygraph at one of these agencies will encounter a structurally similar examination at the DEA.

The DEA polygraph failure rate has been reported at approximately 36%, which is comparable to the FBI and Secret Service rates of around 35% [29]Verified DEA and Federal Agency Polygraph Failure Rates
Confirms DEA had approximately 36% polygraph failure rate, FBI/Secret Service around 35-40%, CBP approximately 65%. By contrast, U.S. Customs and Border Protection has experienced significantly higher failure rates. A 2017 Associated Press investigation found that approximately 65% of CBP applicants who took the polygraph failed [29]Verified DEA and Federal Agency Polygraph Failure Rates
Confirms DEA had approximately 36% polygraph failure rate, FBI/Secret Service around 35-40%, CBP approximately 65%, and more recently the rate has been reported at around 50% [30]Verified CBP Polygraph Failure Rate Reporting
Confirms 65% CBP failure rate from 2017 AP report and more recent estimate of around 50%. CBP uses a specialized format called the Test for Espionage, Sabotage, and Corruption (TES-C), which combines counterintelligence scope testing with suitability topics from the LEPET format [31]Verified TES-C Pilot Implemented as CBP's Primary Testing Format
Confirms CBP uses Test for Espionage, Sabotage, and Corruption (TES-C) combining CI scope with LEPET suitability topics. This format was developed in collaboration with the NCCA specifically for CBP's law enforcement mission [31]Verified TES-C Pilot Implemented as CBP's Primary Testing Format
Confirms CBP uses Test for Espionage, Sabotage, and Corruption (TES-C) combining CI scope with LEPET suitability topics. For more information on the FBI's process, see our FBI Polygraph Exam guide, and for ATF, see our ATF Polygraph Exam guide.

The Test for Espionage and Sabotage (TES) is a separate counterintelligence-focused format primarily used by the Departments of Defense and Energy [32]Verified Psychophysiological Detection of Deception Accuracy Rates Using TES
Confirms TES format achieved 98% correct identification of innocent and 83.3% of guilty examinees. The TES uses directed-lie comparison questions and focuses exclusively on espionage, sabotage, unauthorized disclosure, and unauthorized foreign contacts [32]Verified Psychophysiological Detection of Deception Accuracy Rates Using TES
Confirms TES format achieved 98% correct identification of innocent and 83.3% of guilty examinees. Research at the Department of Defense Polygraph Institute found that the TES format achieved a 98% correct identification rate for innocent examinees and 83.3% for programmed guilty examinees [33]Verified TES Used by Departments of Defense and Energy
Confirms TES is the primary counterintelligence-scope polygraph format used by the Departments of Defense and Energy. The development of directed-lie comparison questions has been supported by extensive peer-reviewed research demonstrating fewer false positives while maintaining strong detection rates [19]Verified Directed Lie Comparison Questions in Polygraph Testing

Research suggests directed-lie comparison questions may offer better countermeasure resistance.

Proven Strategies for Success

DO be completely honest in all disclosures, including your SF-86, pre-test interview, and during chart collection. The DEA's polygraph program is designed to identify deception, and the consequences of being caught in a lie are far worse than the consequences of honest disclosure of past issues.

DO review your entire personal history thoroughly before the examination. Think carefully about all the question categories covered in this guide: criminal conduct, drug use, financial issues, foreign contacts, and professional ethics.

DO get adequate rest the night before, eat a normal meal, and arrive on time. Maintain your normal routine and take prescribed medications as directed.

DO listen carefully to the examiner's instructions and ask questions if anything is unclear. Every question asked during chart collection will have been reviewed with you beforehand.

DO remain still during data collection. Answer with simple "yes" or "no" responses. Breathe normally.

DON'T attempt countermeasures of any kind. This includes physical techniques (biting your tongue, pressing toes, controlled breathing), pharmacological approaches (sedatives, beta-blockers), or mental techniques. Examiners are specifically trained to detect manipulation attempts, and countermeasures detection results in automatic three-year disqualification [3]Verified DEA Special Agent Test Preparation Guide
Confirms polygraph disqualification periods: 3 years for SR/CM results, 2 years for three NO results.

DON'T withhold information during the pre-test interview hoping to "get through" the chart collection. Omissions that surface later in the background investigation create far more serious problems than upfront disclosure.

DON'T ask people who have taken the DEA polygraph to describe their specific questions. Each examination is unique, and preconceived expectations can increase anxiety. For more on this topic, see Can I Refuse a Lie Detector Test? and the Police Polygraph Exam guide.

Post-Hire Polygraph Requirements

Current DEA employees may be subject to periodic polygraph re-examinations throughout their career, particularly those in positions requiring access to Sensitive Compartmented Information (SCI) or Special Access Programs. The Intelligence Community's Security Executive Agent Directive 2 authorizes the use of polygraph examinations for continued eligibility for access to classified information [18]Verified Security Executive Agent Directive 2 (Revised)
Defines CSP, ESP (Full-Scope), and SIP polygraph types; establishes NCCA as primary authority for federal polygraph standards.

The DEA also conducts polygraph examinations on employees who are subject to counterintelligence or misconduct investigations. Additionally, DEA task force officers — state and local law enforcement officers who join DEA-comprised task forces — must also pass polygraph examinations. If a task force officer fails, they are not allowed to continue on the task force [5]Verified DOJ OIG Management Advisory Memorandum - DEA Polygraph (Report 23-095)
Confirms DEA participates in NCCA Quality Assurance Program, 2019 policy change, and OIG finding that 77+ applicants were hired despite failing polygraph.

This ongoing commitment to polygraph testing reflects the DEA's recognition that security threats are not limited to the pre-employment phase. The history of polygraph use in intelligence agencies demonstrates the long-standing role these examinations play in maintaining organizational integrity.
