Getting in
How to become a Polygraph Examiner
Examiners complete a basic polygraph course at a school accredited by the American Polygraph Association, which covers psychology, physiology, question construction, chart analysis and ethics, followed by a supervised internship. Federal examiners train through the National Center for Credibility Assessment.
Many states license polygraph examiners, with rules on training, internship and exams. Many working examiners are former or current police officers and investigators, because agency polygraph units usually recruit from their own ranks. A degree in criminal justice, psychology or a related field helps.

The work
What does a Polygraph Examiner do?
Polygraph examiners conduct structured interviews while an instrument records breathing, heart activity and skin conductance. The examination has several phases: a pretest interview to review the issue and the questions, the recorded testing itself, and analysis of the charts using a validated scoring method.
Examiners work on criminal investigations, pre-employment screening for police and federal agencies, security clearance programs and post-conviction supervision of sex offenders. Private examiners take cases from attorneys and individuals. Polygraph results are often not admissible in court, so much of the value lies in the interview and in the information people disclose during it.
Day-to-day tasks
- Review case files and agree on the issues to be tested
- Conduct pretest interviews and explain the procedure
- Construct relevant and comparison questions
- Operate the polygraph instrument during testing
- Score charts using validated analysis methods
- Conduct post-test interviews and document disclosures
- Write examination reports for agencies and clients
Typical tasks, researched by NueCareer from the sources below.
Working conditions and hours
Examiners work in quiet, controlled exam rooms in police departments, federal agencies, and private offices. Each exam takes a few hours of focused interviewing and analysis. Private examiners may travel to clients, and schedules depend on case load. The work can be emotionally intense when subjects are under stress.
