Verify Your Examiner’s Credentials

Before booking a polygraph test, it is essential to verify the credentials of the examiner. Unfortunately, some individuals who have been expelled from the British Polygraph Association (BPA) for failing to meet professional standards now operate independently in the private market, often misleading clients about their qualifications.

As an independent and professional association, the British Polygraph Society (BPS) is committed to maintaining the highest ethical, scientific, and professional standards in polygraph testing. All of our members are rigorously trained, fully accredited, and dedicated to ethical practice.

To protect yourself and ensure reliable results, always:

  • Confirm that your examiner is a qualified, accredited professional.

  • Request proof of certification before scheduling a test.

  • Verify their membership with a recognized polygraph association.

Choosing an unverified examiner risks undermining the accuracy, validity, and integrity of your examination. By selecting a BPS-recognized examiner, you can be confident that your case will be handled with professionalism, discretion, and scientific accuracy.

Introduction

The BPS Psychophysiological Detection of Deception Terminology Reference is derived from the American Polygraph Association (APA) Terminology Reference, 4th Edition (2022), authored by Donald Krapohl, Mark Handler, and Michael Lynch. While the APA’s work served as the foundation, this adaptation does not represent the official position of the APA.

Over time, the BPS has revised and expanded the resource to reflect UK standards, practices, and advancements in polygraph science. The result is a reference that promotes clarity, consistency, and professionalism across the field—demonstrating the BPS’s ongoing commitment to excellence in psychophysiological detection of deception.
