The American Polygraph Association (APA) is the preeminent polygraph association and is recognized internationally as the main governing body for Polygraph Examiners world wide. Membership in the APA is not a requirement however the APA sets the standards for examiners; in training, in continuing education and in professionalism by requiring adherence to a code of ethics and a set of established standards of practice.

The American Association of Police Polygraphists (AAPP) is the association of law enforcement polygraphists that are governed by specialized standards, objectives, and principals of practice and existing law(s) as well as those of the APA. 

The California Association of Polygraph Examiners (CAPE) is the Association in California that provides a minimum of 32 continuing education hours a year to its members.
