Selecting a Polygraph Examiner


The selection of a polygraph examiner is a critical decision. There are many self taught, and poorly trained polygraph examiners in the marketplace. All examiners listed in this site meet or exceed all requirements of initial training, continuing education hours, and professional certification. Don't trust your polygraph needs to a poorly trained examiner. Rely on the Northwest Polygraph Examiners Association to refer you to an examiner who will be able to give you the very best, professional, polygraph examination. Click on the name of the state in which you are looking for a polygraph examiner. A list of NPEA approved examiners will be displayed.


APA Approved Training
It is essential that a polygraph examiner's initial training be conducted through an American Polygraph Association approved polygraph academy. APA approval assures you that an examiner has received proper training.

Nationally Certified

National Certification is offered through the Northwest Polygraph Examiners Association and other state and national associations. To be Nationally Certified the examiner must have four years experience as an examiner, complete their required continuing education hours each year, and have completed a minimum of two hundred polygraph examinations.

PCSOT Certified

Post Conviction Sex Offender Testing (PCOST) is a speciality within the polygraph profession. PCSOT certified examiners have gone through a special training course and have received a PCSOT Certificate from the American Polygraph Association. To maintain this certification, the examiner must have sixteen (16) hours of continuing education hours every two years relating specifically to the testing sex offenders.


Continuing Education Training

The Northwest Polygraph Examiners Association requires thirty-eight (38) of continuing education hours every three years to remain an active NPEA member. This additional education assures you that each examiner is keeping abreast of new developments in the polygraph field.


Critical Information for Individuals Seeking a Qualified Examiner


Always ask these questions: 

1. What polygraph school or academy did they graduate from and what year? 

For a list of America Polygraph Association accredited schools, visit



2.  If the examiner plans on conducting a test in the State of Oregon, ask them if they have an Oregon Polygraph license? (On the west coast Oregon is the only state that requires a polygraph license) 


3.  Are they a member of any of the following recognized professional organizations:

Northwest Polygraph Examiners Association (NPEA)

American Polygraph Association (APA)

National Polygraph Association (NPA)

American Association of Police Polygraphists (AAPP)

California Association of Polygraph Examiners (CAPE)

If they are not members of one of these five organizations, it is probable that they are not a properly trained polygraph examiner. Any other organizations with similar sounding names probably are NOT professional organizations that enforce membership requirements and provide training. They are likely referral services for scheduling tests with examiners who do not have professional qualifications. 


4. If they offer to give you any kind of lie detector/polygraph test over the phone, they are not polygraph examiners. Hang Up!
