Selecting an Examiner

Updated November 18, 2020

Persons looking for a competent polygraph examiner should look for an examiner who can prove that he/she has graduated from an accredited polygraph school and request from them background information with regard to their credentials. Seek examiners that maintain membership with state and national polygraph organizations and can verify their memberships. Ask the examiner when they last attended polygraph continuing education training. CAPE recommends that examiners complete a minimum of thirty (30) hours of continuing education training every two years.

CAPE Certified Polygraph Examiners are Full or Life CAPE members in good standing that have graduated from an American Polygraph Association (APA) accredited polygraph school. Also, Certified Examiners must have completed a minimum of thirty (30) hours of APA-approved continuing education training and/or continuous education training approved by the CAPE Board of Directors during a two-year period prior to applying for certification or re-certification. Certification is renewed every two (2) years. Full and Life CAPE members have passed a written examination administered by CAPE, passed a background investigation conducted by the CAPE Membership Committee, and provided documentation of a minimum of one hundred (100) polygraph examinations.

There are polygraph examiners in California that are recognized by CAPE to conduct Post-Conviction Sex Offender Polygraph Testing (PCSOT). Each PCSOT trained examiner on this list has successfully completed an APA-approved basic PCSOT course. These examiners have also met the continuing education requirements set forth by the APA and adopted by CAPE for PCSOT testing. Persons trying to locate examiners for sex offender testing should check the CAPE website for the current list of PCSOT examiners who meet CAPE standards.

If you have any question about the Certified Polygraph Examiner list or the PCSOT examiner list, the guidelines, or if you wish to verify examiners on the CAPE Certified or PSCOT list, you are urged to contact the CAPE Board of Directors, using the following email address for this purpose:
