The probation/parole service was established nationally in 1953 to assist the reintegration of ex-offenders. State-level regulations reflect the growth of the service and the need for more explicit definition of the social work and criminal justice purviews. The Baden-Wuertemberg law encompasses court assistance workers, probation and parole officers, as well as social workers in corrections. Its basic principle is that these areas of social work do serve the criminal justice system and should be incorporated within its organizational structure, while allowing social worker autonomy in the performance of actual casework. Details of the State regulations address training, interagency relations, areas of authority, personnel assignments, records confidentiality, counselor-client relations, and responsibilities and limitations of social workers in the criminal justice system.
