After months of doubt and argument, the polygraph gave us both the clarity we needed to move forward. The examiner was professional, compassionate, and explained every step. The report arrived the next morning.
“I was falsely accused by a coworker before an HR hearing. The polygraph report was exactly what I needed. The HR panel accepted it immediately — case closed within the week.”
“My attorney recommended this for our custody case. Handled with total professionalism. The court-ready report was clear and well-documented — our attorney said it was one of the best she’d seen from a private provider.”
Every examination follows the same structured five-stage process. APA Standards of Practice require a minimum 90-minute appointment — we schedule 2 hours to ensure thoroughness.
Discuss your situation confidentially. We assess suitability, recommend the right test, and explain the process.
Your examiner develops targeted yes/no questions specific to your case — reviewed and agreed before testing begins.
Full suitability assessment, process explanation, informed consent obtained, and question review — as required by APA §1.6.2.
Private room. Non-invasive sensors record upper and lower respiration, cardiovascular activity, electrodermal activity, and movement.
Same-day verbal results. Written report delivered within 24–48 hours. All recordings retained per APA standards.
The wording of your questions is one of the biggest factors affecting test accuracy. Poorly formed questions can make results inconclusive or invalid — even with a perfect examiner. One question is ideal, four is the maximum, every question must be answerable yes or no, and no question should take more than 6–7 seconds to ask.
Only events that happened — or didn’t happen — can be tested
Every polygraph question must be grounded in a verifiable factual event — something that either occurred or did not occur. Opinions, beliefs, feelings, and hypotheticals cannot be meaningfully tested because there is no objective true/false answer.
Every question must be answerable with a single word
The polygraph records physiological responses to specific questions. Only binary yes/no answers are permitted — narrative explanations or qualifications during the test corrupt the data. Typically, no answers are expected from suspects and yes answers from witnesses or victims.
One question is ideal. Four is the maximum. Never ask more.
This is one of the most misunderstood aspects of polygraph testing. Many clients want to ask 10 or 15 questions — but this significantly reduces accuracy. A single, well-framed relevant question produces the most reliable result. The upper limit of four relevant questions is where accuracy begins to degrade noticeably.
If a term could mean two things, it must be explicitly defined
Every person who hears the question should interpret it identically. Vague terms — especially relating to sexual acts, financial conduct, or physical contact — must be explicitly defined during the pre-test so the examinee knows exactly what is being asked. Ambiguity in a question creates ambiguity in the result.
Long questions dilute the physiological response signal
Questions that take more than 6–7 seconds to read aloud are too long. The physiological response being measured occurs within a narrow window after the question is asked — excessively long questions either arrive too early or cause the response to fade before it can be clearly recorded.
Only past actions can be tested — not plans, intentions, or hypotheticals
Polygraph testing can only assess whether a person is being deceptive about something that already happened. Intentions, plans, promises, or hypothetical scenarios cannot be verified physiologically — a person may genuinely believe they will behave a certain way, making the question untestable.
The polygraph measures physiological responses to facts — not feelings
Questions about what someone believes, thinks, feels, or values are excluded entirely. These cannot produce a deceptive response because there is no objective factual answer — a person can genuinely hold any belief without it being “true” or “false” in the testable sense.
One question, one fact — never combine two issues into a single question
Compound questions that contain “and” or “or” between two separate issues are not valid for polygraph testing. If the examinee is truthful about one part and deceptive about the other, the result is unreadable. Each question must target a single, specific fact.
Asking the same thing in different ways does not improve accuracy
Because polygraph results are evaluated per examination rather than per individual question, rephrasing the same issue does not add evidential weight — it just increases the total question count and reduces accuracy. Each question must address a genuinely distinct factual issue.
Situational time windows are more reliable than calendar dates
Specific calendar dates can introduce false uncertainty — the examinee may genuinely be unsure of the exact date an event occurred, which can introduce noise into the physiological signal. Situational time frames (“since your wedding,” “while working at that company,” “in the last 6 months”) produce cleaner data.
Charged terms can trigger emotional responses unrelated to deception
Legal terms like “assault,” “rape,” “fraud,” or emotionally loaded words can cause exaggerated physiological responses in truthful people — making them appear deceptive. Plain, direct, neutral language produces the clearest signal. Your examiner will help translate any legally-framed concerns into testable question language.
Your examiner can only work with what the examinee has acknowledged knowing
Polygraph questions must be based on information the examinee has disclosed or acknowledged — not on third-party allegations the examinee has never been confronted with. The pre-test interview is where your examiner establishes what the examinee knows, recalls, and claims — and builds valid questions from that foundation.

Source: The American Polygraph Association’s 2011 meta-analysis of 38 peer-reviewed studies found single-issue diagnostic testing achieved an aggregated accuracy of 89% (CI: 83–95%) with an ~11% inconclusive rate. Accuracy is highest when: (1) a single clearly defined issue is tested, (2) questions are minimal and targeted, (3) APA-validated techniques are used, and (4) examiners are trained to APA standards.

Understanding what each means — including inconclusive — is important before you book.
The physiological data does not indicate deception on the relevant questions. The examinee’s responses are consistent with truthful answers. Commonly referred to as a “pass.”
The physiological data suggests deceptive responses to one or more relevant questions. Commonly referred to as a “fail.” The report documents which questions produced the response.
The data is insufficient to support a definitive finding either way. This is not a fail. Occurs in approximately 10–15% of examinations. A retest may be beneficial — no additional charge if the result arose from an examiner or equipment issue.
Many clients aren’t sure whether they need a private test or a court-ordered one. Here’s a clear comparison to help you understand which applies to your situation.
Admissibility of polygraph evidence varies significantly across US jurisdictions. Most states allow results by stipulation. A few states have specific statutes. Always consult your attorney for case-specific guidance.
Arriving well-prepared improves test quality and your comfort on the day.
Get a full night’s sleep before your appointment. Fatigue can affect physiological baselines. Avoid sleep aids the night before.
No alcohol for 24 hours before testing. Limit caffeine. Do not use recreational drugs — these affect physiological responses.
Tell your examiner about all prescription and over-the-counter medications during the pre-test. This is confidential and for assessment only.
Attempting to manipulate results is detectable and can make truthful examinees appear deceptive. Modern polygraph software makes countermeasures unreliable and risky.
The pre-test interview is confidential. Disclose anything relevant to your examiner. Surprises during the test are worse than disclosures before it.
Arrive 5–10 minutes before your appointment. Normal anxiety is expected and built into the methodology — your examiner will put you at ease.
APA Standards of Practice (§1.2.3) require examiners to assess suitability before testing. Always reviewed during your free consultation.
APA standards involve rigorous training, ongoing education, and adherence to a Code of Ethics and Standards of Practice — last updated August 2024.
The Employee Polygraph Protection Act (EPPA, 1988) restricts — but does not ban — polygraph testing in private-sector employment. The following employer categories are exempt from EPPA restrictions and may request polygraph testing under specific conditions:
Individuals — including job applicants at exempt employers or parties in personal/legal matters — may voluntarily submit to testing at any time. EPPA does not restrict voluntary private polygraph testing. If you’re unsure whether your situation qualifies, call us for a confidential assessment.
Mobile “lie detector” apps, automated quizzes, and tests conducted over the phone or video have no scientific basis and are not recognised by the APA or any professional polygraph body. APA Standards of Practice prohibit any examiner from rendering truthfulness opinions based on non-standard procedures. When clarity matters, choose a provider backed by forensic science, training, and accountability.
In-depth guides to help you understand the science, standards, and legal context before you book.
The American Polygraph Association’s 2011 meta-analysis of 38 peer-reviewed studies found single-issue diagnostic testing produced an aggregated accuracy of approximately 89%, with an upper confidence interval of up to 95% and an inconclusive rate of around 11%. Accuracy is highest when a single clearly defined issue is tested, the number of relevant questions is kept minimal, APA-validated techniques are used, and the examiner is trained to APA standards. We maximise accuracy through validated techniques, government-grade calibrated instrumentation, and strict adherence to APA Standards of Practice.
Pricing varies by test type, number of subjects, and location. A $100 non-refundable booking fee secures your appointment, with the remaining balance confirmed after your case is assessed. Visit our pricing page or send us a message for a confidential quote.
All questions require simple yes/no answers and are developed specifically for your case. Per APA §1.6.3, you review and agree to every question with your examiner during the pre-test phase — there are no surprise questions. Single-issue tests typically include no more than 3 relevant questions — the fewer and more focused, the more accurate the results.
A typical appointment takes approximately 2 hours. APA Standards §1.7.11 require examinations to be scheduled for not less than 90 minutes — we schedule 2 hours to ensure no session feels rushed. This covers the pre-test interview, informed consent, question review, the examination, and a post-test debrief.
Inconclusive is not a fail. It means the physiological data was insufficient to support a definitive finding in either direction — this occurs in approximately 10–15% of examinations and is a recognised outcome under APA methodology. A retest may be scheduled. No additional charge applies where the inconclusive result arose from an examiner or equipment issue.
Yes — strictly confidential. Results are shared only with the person who booked the test. No results are ever disclosed to any third party without explicit written consent — agreed in the consent document signed before testing begins.
No. Nervousness is completely normal and expected. APA-validated methodology accounts for baseline anxiety — your examiner establishes your physiological baseline during the pre-test, and the scoring differentiates between general nervousness and specific deception-linked responses. Attempting to “control” your responses with breathing techniques is actually detectable and can create ambiguous data.
We operate at 140+ professional locations across the US in discreet, controlled office environments. Tests can also be conducted at your private location where conditions are suitable. View all locations or call to discuss arrangements in your area.
Admissibility varies by jurisdiction. Many courts accept results by stipulation of both parties. Even where not directly admissible, results are routinely used in settlement negotiations, mediations, arbitrations, plea bargaining, and custody proceedings. Our reports are prepared to court-ready standards with full documentation of APA-validated methodology and recording certification.
The Employee Polygraph Protection Act (EPPA, 1988) restricts — but does not ban — employer-requested testing. Exempt categories include federal and state government agencies, security services, pharmaceutical firms, defence contractors, and employers investigating specific workplace incidents. Private individuals may voluntarily submit at any time. See our EPPA guide above or call us to discuss your situation.
Appointments are typically available within 48 hours of booking confirmation. Book online 24/7 or send us a message for same-day scheduling assistance. Urgent cases can often be accommodated with expedited arrangements.
