How Polygraph Testing Supports EEOC Investigations for Maryland Employers

Brian Newcomer May 2026 4 min read

When an employee files an EEOC complaint, employers face pressure to conduct a thorough, impartial investigation. Polygraph examinations can be a valuable tool in that process  when used correctly and in compliance with federal guidelines.

What Is an EEOC Investigation?

The Equal Employment Opportunity Commission handles complaints related to workplace discrimination, harassment, and retaliation. Employers are expected to investigate these complaints promptly and professionally.

How Polygraph Can Help

In cases where witness accounts conflict or evidence is unclear, a voluntary polygraph examination can help establish credibility. As a retired police detective and APA-certified examiner with nearly two decades of experience, Brian Newcomer understands the legal standards required for workplace investigations.

Key point

Polygraph examinations are not a replacement for a complete workplace investigation. They can, however, support decision-makers by adding a structured credibility assessment when appropriate.

Important Legal Considerations

Polygraph use in employment situations is governed by the Employee Polygraph Protection Act (EPPA). There are specific exemptions for certain industries and circumstances. We advise employers to consult with legal counsel before requesting any examination.
