There are four basic types of PCSOT examinations:  Instant offense exams, sexual history disclosure exams, maintenance exams, and sex offense monitoring exams.  

Index/Instant offense exam:

This examination is an event-specific polygraph for examinees who deny any or all important aspects of the allegations pertaining to their present sex offense crime(s) of conviction.  The specific Issue test is also used if there is a specific event in question, such as re-offending, or failure to follow one or more of the supervision guidelines.

Maintenance exam:

This test is to thoroughly investigate, either periodically or randomly, the examinee’s compliance with any of the designated terms and condition of probation, parole and treatment rules.

Sexual History exams I and II:

This examination is used to verify the accuracy of the offender's disclosure of his/her sexual history to the treatment provider. It is also used to investigate the examinee’s history of involvement in unknown or unreported offenses and other sexual compulsivity, sexual pre-occupation, or sexual deviancy behaviors.

Disclosure Over Sexual History
The purpose is to verify full and complete disclosure of sexual history for treatment purposes. A sexual history questionnaire, completed by the offender and approved by the treatment provider must be submitted to the polygraph examiner before the examination.

This test covers any sexual re-offending and any other illegal sexual behavior for a designated time period since being on probation/parole.

This test covers any violations of probation/parole conditions not listed above, or violations of treatment rules and contracts, but cannot address both. It is typically done every six months to a year, or as needed.

Each test takes from 2 to 3 hours to complete. Specific areas of concern are identified prior to testing and the relevant questions are formulated to address those concerns. There are no surprises in the questioning. All questions and answers are discussed fully with the subject prior to testing.

Results of the examination are available directly after the test. A verbal report may be made to the requesting agency at that time. A full written report is available within 2 working days.
