In the Commissioner's Directive 800 policy number 36 it states that a recognized gender identity specialist has to confirm that the offender
has satisfied the real life test for a minimum of one year prior to
incarceration. It also states that the recognized gender identity
specialist then has to recommend surgery happen during incarceration.
When looking at this our questions are what qualification do you need
to be recognized as a gender identity specialist? And who decides
within the prison system which specialist to use with transgendered
inmates?
