Government & Security Clearance Polygraphs — What Private Examiners Can and Can’t Do
The straight answer before anything else: official clearance polygraphs are run only by the government itself
If you are facing a CIA, NSA, FBI, DoD, or law-enforcement polygraph, no private company — including us — can administer that exam, substitute for it, or influence its outcome. This page explains exactly how the official formats work (CI-scope, full-scope/lifestyle, LEPET), and the three things a private polygraph can legitimately do in this space: process familiarization for candidates, lawful verification exams within EPPA limits, and clearing your name on personal matters that surface in a background investigation.

Official government polygraphs are conducted only by the government
Security-clearance polygraphs (CIA, NSA, FBI, DIA, DoD), federal and police pre-employment polygraphs (LEPET), and voice-stress screenings (CVSA) used by some departments are administered exclusively by the hiring or adjudicating agency’s own examiners, on the agency’s own instruments, under the agency’s own rules. A private polygraph company cannot administer these exams, cannot sit in for them, cannot certify you as “cleared,” and cannot overturn an agency’s polygraph decision. Anyone who tells you otherwise is selling something that does not exist.
What a private examiner can honestly offer is narrower — and it’s described in full further down this page: familiarization with the process, lawful verification testing within the strict limits of the Employee Polygraph Protection Act, and independent exams to address personal or legal matters that appear in your background investigation.
The three main government polygraph formats — and what they cover
Which format you face depends on the agency and the level of access. All are screening exams: broader in scope, and adjudicated differently, than the single-issue diagnostic exams private examiners run.
How an official clearance polygraph typically unfolds
Details vary by agency, but the shape of the day is consistent. Knowing it in advance is the single most effective, legitimate way to reduce anxiety.
Conditional Offer
The polygraph is scheduled after a conditional offer of employment or as part of periodic reinvestigation for an existing clearance.
Pre-Test Interview
Often the longest phase. The agency examiner reviews every topic and every question with you before any charts are run. There are no surprise questions.
In-Test Phase
Sensors record respiration, cardiovascular and electrodermal activity while the agreed questions are asked across several charts.
Post-Test Discussion
The examiner may revisit topics that produced significant responses and invite explanation. Sessions can be continued to a second day.
Adjudication
Results go to the agency’s adjudicators as one factor in the whole-person clearance decision. The examiner in the room does not make the final call.
What a private polygraph can genuinely do in this space
Not “get you cleared.” Not “beat the test.” These are the three services we actually provide, with their limits stated plainly.
Practice & Familiarization for Candidates
A full, realistic single-issue exam so you experience the instrumentation, the pre-test interview, and the pacing of a real examination before your agency date. For most candidates the unknown — not the questions — is what drives anxiety. Be aware: agencies discourage “coaching,” and we do not teach countermeasures or answer strategies. What we offer is process literacy, nothing more.
Lawful Verification for Contractors & Employees
Where the law allows it, a private exam can verify a specific factual issue — for example a contractor voluntarily documenting the truth about an alleged security-policy breach. The Employee Polygraph Protection Act sharply limits when any private employer may request testing, so read the EPPA section below and our workplace polygraph & EPPA guide before assuming a workplace exam is possible.
Clearing Your Name on Background Issues
Background investigations surface personal and legal history: an old accusation, a family dispute, an ex-partner’s allegation, a contested incident. A private single-issue exam can produce an independent, documented result addressing that specific matter — useful to you, your attorney, or the people around you. It does not bind the agency, but it can resolve the underlying human dispute.
What a candidate familiarization exam covers
Structured as a genuine APA-format single-issue examination on a factual question from your own history, so the experience is real — not a role-play.
Pre-test interview, informed consent, question review, chart collection, and debrief — the same structure agency exams follow.
You sit with the actual sensors — respiration, cardiovascular, electrodermal — so the physical experience holds no surprises.
Understanding why nervousness alone does not read as deception: validated techniques baseline your normal physiology first.
Ask anything about how examinations work. Your examiner is individually assigned to you and your case after booking.
We will not teach breathing tricks, muscle control, mental manipulation, or any “how to pass” technique. Countermeasure attempts are detectable and can sink an otherwise truthful candidate.
We will not script answers or advise you what to disclose. Agencies discourage coaching, and your only safe strategy on an official exam is complete honesty.
Private employers largely cannot require a polygraph
The federal Employee Polygraph Protection Act of 1988 prohibits most private employers from requiring, requesting, or even suggesting a polygraph for employees or applicants — and from acting on the results or on a refusal. This matters here because defense contractors and security firms often assume they can “pre-screen” staff with private polygraphs. In most cases they cannot.
Narrow exemptions exist — government agencies themselves, certain security-service and pharmaceutical employers, and ongoing-incident investigations under strict conditions — and an individual may always volunteer for a test on their own initiative. The rules are technical and the penalties are real, so if you are an employer, talk to us and to counsel before requesting anything.

Is a private exam right for your situation?
We turn away bookings that we cannot honestly serve. Here is where the line sits.
A private exam can help if…
- You have an agency polygraph coming up and want to experience the process once, for real, before the day.
- Anxiety about the unknown — not about your answers — is your main worry.
- A specific personal or legal matter in your background needs an independent, documented resolution.
- You are an employer within an EPPA exemption, or an employee volunteering to clear yourself in a specific investigation.
- You and your attorney want a confidential result before deciding anything else.
A private exam cannot help if…
- You want a substitute for, or exemption from, an official agency polygraph — that does not exist.
- You failed an agency exam and want a private result to overturn the decision — agencies do not accept external results.
- You want to learn techniques to “pass” a government polygraph — we refuse this work, without exception.
- You are a private employer outside the EPPA exemptions wanting to screen staff — that would be unlawful.
- You are looking for a “certificate of clearance” — only government adjudicators grant clearances.
How our private examinations run
Security-clearance polygraph FAQ
Can a private company administer my security-clearance polygraph?
No. CIA, NSA, FBI, DoD, and law-enforcement polygraphs are administered exclusively by the agency’s own examiners. No private provider is authorized to conduct, replace, or certify an official clearance or pre-employment polygraph — and we will never claim otherwise.
I failed an agency polygraph. Can a private test overturn the decision?
No. Agencies do not accept private polygraph results as a substitute for their own, and a private “pass” will not reverse an adjudication. Your recourse is the agency’s own appeal or reconsideration process. A private exam can, at most, help you resolve an underlying personal or legal dispute on its own merits.
Can I retake a failed government polygraph?
Only if and when the agency offers it. Retests, continuations, and reconsideration are scheduled at the agency’s discretion under its own rules — a private examiner cannot arrange or accelerate one.
Do failed agency polygraph results transfer between agencies?
Each agency runs its own examinations, but results and adjudication history can be shared across the federal security-clearance system and may be considered in later applications. A poor result at one agency does not automatically disqualify you elsewhere, but it does not simply disappear either.
Is a practice polygraph “coaching”? Will it hurt my application?
Agencies discourage coaching — meaning scripted answers and countermeasure training, which we refuse to provide. A familiarization exam is different: it is process experience, like a mock interview. It is confidential and not reported to anyone. That said, on the official exam your only safe strategy is complete honesty; no preparation changes that.
Can my employer make me take a polygraph for a security job?
If your employer is a government agency, yes — EPPA does not apply to them. Most private employers cannot require or request one, with narrow exemptions (certain security services, pharmaceutical firms, national-defense contractor screening, and tightly controlled specific-incident investigations). See our EPPA guide.
Will nervousness make me fail?
Nervousness alone does not read as deception. Validated techniques establish your physiological baseline first and compare responses against it — every examinee is nervous, and examiners expect that. This is true of both agency exams and private ones.
How accurate is a private polygraph?
Properly conducted single-issue examinations reach accuracy of up to ~95% (APA meta-analytic research), which is why we keep private exams to a single, well-defined issue with no more than three relevant questions.
