How to Choose a Credibility Assessment Examiner: A Professional's Honest Guide

Howdy, folks — Jerry Thomas here. If you ever find yourself in a situation where you need some answers and you're thinking about hiring a private credibility assessment examiner, choosing the right professional is one of the most important decisions you'll make. Whether you're dealing with a personal matter, a workplace dispute, or a legal issue, the examiner you choose will have a direct impact on the quality and reliability of your results. Here's what you need to know.

1 Look for Proper Credentials

The first step is to verify the examiner's credentials. A qualified credibility assessment examiner should be trained by and affiliated with a recognized professional organization — such as the American Polygraph Association (APA), the American Association of Police Polygraphists (AAPP), or a reputable state-level organization. These affiliations indicate the examiner has met established training standards and is committed to professional development.

It is important to understand that not all states require a license to practice as a polygraph examiner. Texas, for example, deregulated polygraph licensing statewide on September 1, 2021 — meaning no state license is required to conduct examinations in Texas. In states without a licensing requirement, credentials become even more critical. Ask the examiner directly: What training did you receive? Where? When was the last time you attended a national or state polygraph continuing education program? A qualified professional will welcome those questions — they should not make you feel uncomfortable for asking.

2 Experience Matters

Credentials tell you an examiner was trained. Experience tells you they've been tested. Ask how long the examiner has been practicing, how many examinations they've conducted, and what types of cases they typically handle. Some examiners specialize in criminal matters, pre-employment screening for law enforcement, Post-Conviction Sex Offender Testing (PCSOT), or private personal matters. Make sure their experience matches your specific situation.

As someone who has held a contract with a juvenile agency for many years and has conducted hundreds of juvenile examinations since 2007, I can tell you firsthand: pre-teens and teens do not always behave like adults. Some will walk around the room during the pre-test interview. Some are too shy to ask clarifying questions. Others are simply not yet mature enough to be tested at all. An examiner who has only worked with adults may not recognize these dynamics — or know how to respond to them appropriately.

3 Check Reviews and References

Just as you would when hiring any professional, take the time to look at online reviews and ask for references. Look for consistent feedback about the examiner's professionalism, communication, and the accuracy and usefulness of their results. If the examiner is reluctant to provide references or deflects questions about their track record, that is a red flag worth taking seriously.

Testimonials from attorneys, probation officers, or treatment providers who have worked with the examiner over time carry particular weight — these are professionals who have seen the results and have a professional stake in their accuracy.

4 Ask About the Testing Process

A professional examiner should be able to walk you through exactly what to expect — from the pre-test interview to chart collection to result interpretation. They should explain how long the examination takes, what the test format involves, how results are scored, and how the final report will be communicated. Transparency here is not optional; it is a mark of professional confidence.

If an examiner is evasive about their methodology, dismissive of your questions, or unable to explain their process in plain language, that is cause for concern. Trust your instincts — if something does not feel right, it probably is not.

5 Consider the Cost — But Keep It in Perspective

Cost is a legitimate factor, but it should not be the deciding one. Ask for a clear, written breakdown of all fees before you commit. A reputable examiner will provide that without hesitation. Be cautious of unusually low fees — in this field as in most, price tends to reflect training, experience, and equipment quality. A proper examination takes time, preparation, and professional judgment. That has value.

At the same time, the most expensive examiner is not automatically the best one. The right combination of credentials, experience, and fit for your specific situation matters more than the fee alone.
