The U.S. Probation and Pretrial Services System, also called the Office of Probation and Pretrial Services, part of the Administrative Office of the United States Courts, is the office of the federal judiciary of the United States. It serves the United States district courts in all 94 federal judicial districts nationwide and constitutes the community corrections arm of the Federal Judiciary. It administers probation and supervised release under United States federal law.
The first legislation for Federal Probation Law was introduced in 1908, one of which was prepared by the New York State Probation Commission and the National Probation Association (later known as the National Council on Crime and Delinquency) and introduced before Congress by United States Senator Robert L. Owen of Oklahoma. The bill provided for a suspension of a sentence, in U.S. District Court, and a sentence of probation. The bill also provided for compensation of $5 per diem for Federal Probation Officers. This first attempt did not pass and through 1909 to 1925 there were 34 bills introduced to establish federal probation law.
In 1925, the Federal Probation Act was introduced by Senator Copeland as S.1042 and Representative Graham as H.R. 5195. The U.S. Senate passed in unanimously but the House passed the law by a vote of 170 in favor and 49 opposed. On March 4, 1925, President Calvin Coolidge, a former Governor of Massachusetts and very familiar with the benefits of a functioning probation system, signed the bill in law. This Act gave the U.S. Courts the power to appoint Federal Probation Officers and authority to sentence defendants to probation instead of a prison sentence. It later gave U.S. Probation Officers the responsibility of supervising offenders granted parole by the United States Parole Commission, military offenders and pretrial supervision. The responsibility of the United States Probation Service was first under the United States Department of Justice, under the supervising authority of the Federal Bureau of Prisons, however, in 1940 the Administrative Office of the U.S. Courts was established and assumed the responsibility.
