What Professional Standards Does the American Polygraph Association Set for Polygraph Examiners?
Updated
The American Polygraph Association (APA) sets professional standards for polygraph examiners through published standards of practice that cover techniques, instrumentation, analysis, research, training, and continuing education. Founded in 1966 and describing itself as the world's leading association dedicated to evidence-based scientific methods for credibility assessment, the APA states that it promotes the highest standards of professional, ethical, and scientific practice for its 2,700+ members. These standards apply to APA members—examiners in private practice, law enforcement, and government—rather than to all polygraph examiners everywhere.
The Scope of APA Standards
According to the association, its standards for professional practice address six areas:
| Area | What the standard covers |
|---|---|
| Techniques | The examination methods examiners are expected to use |
| Instrumentation | The equipment used in polygraph examinations |
| Analysis | How examination data is interpreted |
| Research | The scientific basis underlying practice |
| Training | Preparation of examiners |
| Continuing education | Ongoing professional development |
The inclusion of research and continuing education alongside technique and instrumentation reflects the association's stated emphasis on evidence-based practice: standards are meant to rest on scientific methods for credibility assessment, not only on established procedure.
Ethical Practice Requirements
The APA frames its standards as professional, ethical, and scientific together. Its stated purpose is to provide training, model best practices, and offer professional resources for "ethical and evidence-based detection of deception." Membership consists of professional polygraph examiners, educators, and researchers who, in the association's description, share a commitment to the public interest through valid and ethical polygraph practices.
One concrete example of ethics guidance appears in a recent announcement from APA President McCloughan. The association reported hearing concerns about service-based companies that may assign a polygraph examiner to an examination without first obtaining the examiner's knowledge or consent. Although the APA had not received formal complaints from members on the issue, it advised members to exercise due diligence when accepting referrals or assignments from third-party service providers—verifying the identity of the requesting party, the terms of the engagement, and that the assignment has been authorized with the examiner's knowledge and agreement.
What This Means in Practice
For someone evaluating an examiner or considering APA membership, the standards point to a few checkable conditions:
- Technique and analysis are standardized. An examiner following APA standards works within published methods for conducting and interpreting examinations, rather than ad hoc procedure.
- Training and continuing education are expected. The standards cover both initial training and ongoing development, so an examiner's credentials should reflect more than a one-time course.
- Ethical conduct extends to how work is accepted. The referral guidance above shows that ethical practice includes confirming who is requesting an examination and on what terms before agreeing to conduct it.
- The evidence base matters. The association positions its standards around scientific, evidence-based credibility assessment, which is the frame to use when asking an examiner about the research behind their methods.
Limits to Keep in Mind
The page describes the APA as a professional membership association; it does not state that its standards are legally binding on all examiners, nor does it describe an enforcement or discipline process. Membership figures (2,700+) and the six standard areas are as the association presents them. Questions about whether a specific examiner is an APA member, or about the current text of any particular standard, are best directed to the association through the contact channels listed on its site.
