The polygraph is a recording instrument that monitors and records the respiration, circulation, and perspiration baselines and changes; certain changes are associated with fear of detection, which is the reason why many people lie. Every licensed polygraph examiner in Texas has either attended a rigorous polygraph school to learn to use the polygraph instrument and conduct the associated interviews, or have been through a long preceptor-training program with a competent examiner. Prior to receiving a polygraph license, each examiner has to pass a four-phase examination administered by the Texas Polygraph Examiners Board. Following licensure, each examiner should receive specialized training in the area of sex offender testing prior to conducting clinical polygraphs on sex offenders.

Polygraph examinations should only be conducted by licensed examiners that meet the "Guidelines for Clinical Polygraph Examination of Sex Offenders" Revised February 1998, WordPerfect 6.1 format, 81 KB. These guidelines are established by the Joint Polygraph Committee on Offender Testing (JPCOT). The polygraph can be effective in encouraging disclosure of prior events and adherence to rules.
