PCSOT is the Post Conviction Sex Offender Testing required for federal, state and county probation.

There are four basic PCSOT polygraph examinations: 
Instant/ Index Offense Polygraph Examination

Instant/ Index Offense Polygraph Examination

This examination is conducted for a specific event, where the accused denies any or all of the allegations pertaining to their present sex offense crime convictions. This polygraph examination is also conducted in a specific offense event, such as a re-offense or violating any of the supervision guidelines.
Disclosure of Sexual History

Disclosure of Sexual History

This polygraph examination is based on a sexual history questionnaire completed by the sex offender and submitted with the approval of the treatment provider. It serves to verify the complete disclosure of the sex offender’s sexual history for treatment purposes.

This examination is effective in discovering unknown and unreported sexual offenses, as well as unacknowledged sexual deviances, obsessions, and proclivities. This in-depth discovery process aids both treatment and law enforcement.

The examination takes between 2 to 3 hours in total. These examinations are designed to address specific areas of concern and the questions are reviewed and chosen to answer those concerns
Monitoring

Monitoring

This polygraph examination covers any sexual offenses in addition to any re-offending during a specific time period during parole or probation. These examinations are used to concentrate a time period that has come into question, whether through the investigative or treatment process.
Maintenance

Maintenance

The maintenance polygraph examination tests for any sexual re-offending and any illegal sexual activity while being on parole or probation. This examinations are designed to discover any sexual offenses, as well as any parole, probation, or treatment contract violations. However, they are tested separately for law enforcement and treatment purposes.

Maintenance polygraph examinations can test for any parole or probation violations, or violations of treatment rules and contracts. Parole and probation violations require their own test. Treatment violations are tested separately. These tests are usually conducted every six months to a year on an as-needed basis.
As with all polygraph examinations, there are no surprise questions. All questions and answers are discussed and fully understood by the examinee. The polygraphic examination process measures the physiological responses during the answers to those questions and determines their veracity.

The examination takes between 2 to 3 hours in total. These examinations are designed to address specific areas of concern and the questions are reviewed and chosen to answer those concerns.

A verbal report of the results can be provided immediately after the test to the authorized agency. Written reports will be available within five business days.

Maintenance polygraph examinations can be arranged to be conducted at any governmental or treatment agency upon request.
