Verify Your Examiner’s Credentials

We strongly advise the public to verify the credentials of any polygraph examiner before booking a test. Many individuals who were expelled from the British Polygraph Association (BPA) due to not meeting professional standards now operate independently in the private market, misleading clients about their expertise.

As a professional and independent polygraph association, the British Polygraph Society (BPS) upholds the highest ethical and scientific standards in polygraph testing. Our members are rigorously trained, accredited, and committed to ethical practice.

Before scheduling a polygraph examination, ensure that your examiner is a qualified and accredited professional. Choosing an unverified examiner could compromise the accuracy and integrity of your test. Always request proof of certification and verify their membership with a recognized polygraph association.

Polygraph Terminology Reference

BPS Psychophysiological Detection of Deception Terminology Reference

Last Update: 2025

Introduction

The BPS Psychophysiological Detection of Deception Terminology Reference is based on the American Polygraph Association’s (APA) Terminology Reference, 4th Edition (2022), authored by Donald Krapohl, Mark Handler, and Michael Lynch. While the APA’s work provided the foundation, it does not reflect their official position. Over time, the BPS has adapted and edited this resource to align with UK standards and advancements in polygraph science. Our reference ensures clarity, consistency, and professionalism in the field, reflecting the BPS’s commitment to excellence in psychophysiological detection of deception.
