The fastest way to verify an examiner's credentials is through the American Polygraph Association website. If they are listed as a current APA member, you know they have graduated from an accredited programme, passed competency examinations, and committed to the APA's ethical code and ongoing professional development requirements.
Some companies use clever wordplay to create an impression of APA affiliation. Phrases like "APA-accredited institution," "trained to APA standards," or "recognised training" do not mean the examiner is an APA member. If not expressly stated that the company's examiners are members of the American Polygraph Association, the affiliation is likely misrepresented.
There are instances where unqualified and unaffiliated examiners have attempted to use "training certificates" to create the impression of APA membership. Always ask for the examiner's personal APA membership certificate — and verify it on the APA website. A legitimate professional will welcome this request.
Save Time: One Verification Does Everything
Your polygraph examiner is not applying for a job with you. You do not need to collect CVs, academic transcripts, or training portfolios. A single APA membership verification confirms training, competency, ethical compliance, and ongoing professional development in one check.

Scam Warning Signs & Red Flags
Phone or Internet Tests
If offered a polygraph over the phone or internet, this is a scam. No technology currently exists that detects deception remotely. Do not book or pay money for it.
No APA Membership
Cannot provide proof of current APA membership — not just "accredited training" but actual membership. Verify directly on the APA website.
Suspiciously Low Pricing
Tests offered significantly below $500 suggest unqualified examiners, outdated equipment, or corners being cut on methodology and quality review.
Free Webmail Contact
No dedicated business email connected to their domain. Using free webmail services suggests a lack of professional infrastructure and stability.
No Refund or Cancellation Policy
Provider offers no refund under any circumstances and does not publish clear terms. Professional companies have transparent cancellation policies.
Only Website Reviews
Reviews only on their own website with no independent verification. Legitimate providers are listed on independent platforms like Trustpilot.
Beware of Examiners Who Criticise Competitors
Occasionally, examiners who are struggling for business will publicly criticise other APA-accredited professionals rather than competing on their own merits. This behaviour is unprofessional and often signals an examiner who prioritises self-promotion over ethical practice. The first rule of professional marketing is: compete on quality, not on attacking others.
Fees, Pricing & Cancellation Policies
Understanding Polygraph Pricing
The cost of a polygraph examination fluctuates based on the number of questions administered, the test type, and the location. A single-issue polygraph test typically ranges between $500 and $900. Exercise caution with offers substantially below or above this range.
Prices may increase to account for travel expenses when the examiner must travel to remote locations or provide on-site corporate testing. The quote you receive should be all-inclusive and fixed — ask specifically about any hidden fees before scheduling.
Cancellation policies: Most providers charge a non-refundable booking fee. If you need to cancel, you will typically be offered an alternative date (usually within 30 days). With at least 48 hours' notice, the full amount less the booking fee is normally refunded. If a provider offers no refund under any circumstances, consider looking elsewhere.
Do not assume the cheapest quote is the best option. Professional-grade equipment, APA-accredited training, and validated methodology have real costs. A cheap test that produces unreliable results costs far more in the end — as many people have learned too late.
Duration of Test & Results
The average time allocated for a lie detector test is approximately 2 hours depending on the complexity of the issue. This encompasses the pre-test interview (where the examiner explains the process, reviews questions, and addresses concerns), the data collection phase (where physiological responses are recorded), and the post-test discussion.
The examiner may be able to give you verbal results immediately after the test. The fully analysed written report is usually available within 24–48 hours.
Terminology Matters
Although commonly called a "lie detector test," the process detects deception or the lack of it. Your report should use professional terminology: "No Deception Indicated," "Deception Indicated," or "Inconclusive." If it uses informal language like "passed" or "failed" without scientific terminology, ask why.

Evaluating Reviews & Reputation
Most consumers check reviews before making a purchase, and polygraph testing should be no different. However, there is a critical distinction between independent reviews and self-published testimonials.
Legitimate providers are listed on independent review platforms such as Trustpilot, which work to ensure that reviews are genuine, verified, and cannot be faked or selectively published. Lie Detector Test currently holds the most reviews of any polygraph provider in the United States on Trustpilot.
If a provider only displays reviews on their own website with no independent verification, ask to speak to a previous client. Self-published reviews can be fabricated — independent platforms cannot.
Company Stability & Professionalism
Professional Email Domain
Email addresses connected to their website domain, not free webmail accounts. Dedicated business email indicates infrastructure and stability.
Established Online Presence
A professional website with clear service pages, pricing, terms, and location information — not a single-page site with minimal detail.
Clear Terms & Policies
Published terms of service, cancellation policy, privacy policy, and ethical standards. Transparency signals professionalism.
Dedicated Support Team
A customer support team as the first point of contact — not an examiner doubling as a switchboard operator, which raises questions about capacity.
Physical Locations
Professional testing venues — private offices in established locations, not homes, vehicles, hotel rooms, or public spaces.
Background-Checked Examiners
All examiners screened with background and criminal record checks in addition to qualifications verification.
Customer Care & Communication
At Lie Detector Test, we have a dedicated customer support team as the first point of contact. They can answer queries about the process, pricing, locations, and scheduling. If you need to speak with a polygraph examiner directly, the support team will arrange it.
Our polygraph examiners are not switchboard operators — they are conducting examinations and analysing results. If a company has its examiners answering phones throughout the day, consider how large or busy that organisation really is.
A good indicator of customer service quality is response time to initial enquiries. If a provider responds promptly to your contact form or call, they value every client. Slow or dismissive responses often indicate the service experience that follows.
