Backster School 50th Anniversiary
APA Logo

Backster Associates, Inc., also conducts polygraphs for: Criminal; Civil; Fidelity; Pre-Employment; Immigration; PCSOT; as well as Forensic Security Interviews. Serving the Polygraph Profession since 1959!

The Backster School of Lie Detection remains loyal to the Backster Zone Comparison Technique, however we now feature the Matte Quadri-Track and we teach other  validated techniques and TDA scoring methodology including: Federal Zone/Bi-Zone; AFMGQT, Utah, etc.

For years there has been a mis-understanding of Law Enforcement Examiners that they not be trained in PCSOT as they will generally not be doing PCSOT Testing.  This is incorrect as in the case of a missing child or sexual assault ... who are the prime suspects!  We have started a special 3-day training "Advanced, 3-day Sexual Offense Polygraph Training for Law Enforcement Examiners" to teach the basics for the number(s) and type of exams that sex offenders take.  Please consult our schedule of courses.
