Polygraph Fraud Alerts & Consumer Protection

Protecting you from scams, unqualified examiners, and fraudulent practices

The US polygraph industry is not federally regulated. That means unqualified practitioners, fake reports, scam apps, and deceptive marketing can put consumers at risk. Our fraud review team monitors the industry and publishes alerts to help you make safe, informed decisions. If you encounter suspicious practices, report them.

How to Protect YourselfSix Checks

Six essential checks before you book anywhere

1Verify APA Membership

Search the examiner’s name on the APA website. If they are not listed as a current member, do not proceed.

2Check Test Duration

A legitimate test takes approximately 2 hours. Anything under an hour means essential phases are being skipped.

3Demand a Written Report

Must include examiner credentials, methodology, questions, physiological analysis, and peer review verification.

4Professional Office Only

Testing should be conducted in a private, controlled environment — not homes, vehicles, hotels, or public spaces.

5Question Low Prices

Professional testing costs $500–$900. Significantly lower pricing indicates unqualified examiners or skipped methodology. See our pricing page.

6Reject Remote Testing

No technology can detect deception over the phone, internet, or video call. Any provider offering remote testing is a scam.

We publish these alerts because consumer protection is not optional — it is an obligation for any provider that takes this profession seriously.

Verified examiners. Verified results. Verified trust.
