The Court Services and Offender Supervision Agency for the District of Columbia (CSOSA) was established by the National Capital Revitalization and Self-Government Improvement Act of 1997 (the Revitalization Act) to perform community supervision of D.C. Code offenders.
Following a three-year period of trusteeship, CSOSA was certified as an independent, federal Executive Branch agency on August 4, 2000. Under the Revitalization Act, CSOSA combined three separate entities of the District of Columbia government into a single agency. The new agency assumed the adult probation function from the D.C. Superior Court and the parole function from the D.C. Board of Parole (which was disbanded). The D.C. Pretrial Services Agency, responsible for supervising pretrial defendants, became an independent entity with CSOSA with its own budget and organizational structure.
The Revitalization Act transferred parole supervision functions to CSOSA and parole decision-making functions to the United States Parole Commission (USPC). On August 5, 1998, the parole determination function was transferred to the USPC, and on August 4, 2000, the USPC assumed responsibility for parole revocation and modification with respect to felons.
CSOSA's mission is to increase public safety, prevent crime, reduce recidivism, and support the fair administration of justice in close collaboration with the community.
