The mission of the Montgomery County Pre-Trial Assessment and Supervision Units is to ensure all eligible defendants are afforded the opportunity for Pre-Trial release and to enhance public safety by providing community monitoring and referral to services that will increase the likelihood of appearance for trial and to reduce the risk for re-arrest.

The Pre-Trial Services is responsible for assessing newly arrested defendants for the possibility of release into the community while awaiting trial and for follow through with supervising those defendants safely in the community. The Pre-Trial Services Division also supervises those defendants who are offered diversion from trial in return for satisfactorily completing a community services or substance abuse program.

There are four independent programs within the division: Pre-Trial Assessment Unit, Pre-Trial Supervision Unit, Alternative Community Service Program (ACS), and Intervention for Substance Abusers Program (IPSA).
