Tristar333, you are most likely at the mercy of the "treatment triangle" -- a conceptual triad consisting of your parole officer, your therapist, and your polygraph operator.

To a significant extent, those empowered individuals can make up the rules as they see fit.

The APA indeed publishes model policies -- such as one on Post Conviction Sex Offender Testing (PCSOT)-- but the organization  has no real teeth. In many cases, the APA is but a paper tiger.

As for going back beyond two years, such a circumstance may be necessary if a convicted sex offender has been in the community for an appreciable length of time, but has not yet subjected to a PCSOT "test."

In that case, relevant questions may be introduced thusly:

"Since your release from prison, have you..."

      -or-

"Since your conviction, have you..."


As for polygraph losing its effectiveness over time, the APA has not -- to the best of my knowledge -- published any recommendations for time delimited cut-offs. It is not unusual for polygraph operators to conduct exams on individuals with suspected involvement in events alleged to have happened decades ago.
