The DC Department of Corrections (DOC) is one of 17 agencies under the District of Columbia's public safety cluster. The DOC mission is to provide a safe, secure, orderly and humane environment for the confinement of pretrial detainees and sentenced inmates, while affording those in custody meaningful rehabilitative opportunities that will assist them to constructively re-integrate into the community.DOC currently operates one of the 50 largest municipal jail systems in the country with an average daily population of approximately 2,600 inmates.The DOC system is comprised of two primary correctional facilities—the Central Detention Facility also known as the DC Jail and the privately operated Correctional Treatment Facility. In addition, DOC contracts with four privately operated halfway houses for the community placement of male/female inmates that offer a variety of educational opportunities and other programming services.In 2012, DOC achieved national reaccreditation of its medical and mental health service delivery system by the National Commission on Correctional Heath Care (NCCHC). NCCHC accreditation is recognized as the gold standard for jail health care programs. DOC has also received recognition for its pioneering efforts in automatic HIV/AIDS testing, as well as its commitment to innovative thinking.Both the DC Jail and Correctional Treatment Facility are fully accredited by the American Correctional Association (ACA). This designation reflects compliance with critical safety, security, operational and programmatic mandates.
