The American juvenile justice system is the primary system used to handle minors who are convicted of criminal offenses. The system is composed of a federal and many separate state, territorial, and local jurisdictions, with states and the federal government sharing sovereign police power under the common authority of the United States Constitution. The juvenile justice system intervenes in delinquent behavior through police, court, and correctional involvement, with the goal of rehabilitation. Youth and their guardians can face a variety of consequences including probation, community service, youth court, youth incarceration and alternative schooling. The juvenile justice system, similar to the adult system, operates from a belief that intervening early in delinquent behavior will deter adolescents from engaging in criminal behavior as adults.
