This civil commitment process is determined by Massachusetts General Law Chapter 123A. On January 6, 2020, there was 572 inmates in general population beds.

The mission of the Massachusetts Treatment Center is to promote public safety through the responsible management of criminal and civil commitments while providing a comprehensive and effective sex offender treatment program.

The facility is adjacent to the state's Old Colony Correctional Center.
