In case you aren't familiar with it, PREA is the Prison Rape Elimination Act of 2003.

The National PREA Resource Center has clarified guidelines set in 2012 regarding the treatment of transgender inmates within the prison system, stating Thursday that any policy that houses transgender or intersex inmates based exclusively on external genital anatomy violates PREA standards.

Standard 115.42(c): In deciding whether to assign a transgender or intersex inmate to a facility for male or female inmates, and in making other housing and programming assignments, the agency shall consider on a case-by-case basis whether a placement would ensure the inmate’s health and safety, and whether the placement would present management or security problems.

(e) A transgender or intersex inmate’s own views with respect to his or her own safety shall be given serious consideration.

Think about that: This is a better situation than transgender people are facing in North Carolina in regards to restrooms usage.
