The National Institute of Justice states that the development of American Day Reporting Centers during the 1980’s was sparked by two primary factors: (1) a rising awareness as an intermediate sanction in Great Britain and (2) growing prison and jail crowding, which propated the American corrections officials to develop structure alternatives to confinement. In 1972, British Parliament was persuaded by British Probation officials that imprisonment and individual casework for certain chronic but not non-serious offenders were not effective, thus establishing four day treatment Centers. In, doing so, British officials noted that many such offenders were imprisoned not because they posed a substantial risk to the public, but because they lacked the basic skills to survive lawfully and were frequent dependent on drugs or alcohol. In America during the early 1980’s, Federal, State, and local officialsbegan to change the sentencing and correctional systems in seven areas: sentencing policies, sentencing practices, offender supervision, offender control, rates of arrest and prosecutions, publix attitude toward crime and criminals, and classification of offenders according to risk and need. These changes caused considerable strain on the criminal justice system and led to an environment open to new ideas in corrections practices. Also in America, Federal, State, and local officials began adapting to the new strain on prisons and jails and used “split” sentences to combine a period of incarceration with a period of community supervision. In the early 1980’s, Probation agencies introduced a range of intermediate sanctions to “bridge the gap” between prison and probation, and to rebuild political support for probation by making community-based sanctions significant punishments. As the new probation options were implemented, judges increased the number of conditions imposed at sentencing and also added new types of conditions (such as drug testing, curfews, and mandatory treatment) and violations were easy to detect. Due to this, probation and parole violations became one of the main sources of prison admissions during this time.
