It was created on January 2, 1991 by virtue of Republic Act No. 6975 also known as the Department of the Interior and Local Government Act of 1990. Prior to its creation, the Office of Jail Management and Penology of then Philippine Constabulary - Integrated National Police was the agency handling the local penology of the Philippines. It aimed to separate the agency from the national police, reporting directly to the Secretary of the Interior and Local Government.
