In American criminal justice systems a youth detention center, also known as a juvenile detention center (JDC),juvenile hall or, more colloquially as juvy, is a secure prison or jail for minors under the age of 18, often termed juvenile delinquents, to which they have been sentenced and committed for a period of time, or detained on a short-term basis while awaiting court hearings and/or placement in such a facility or in other long-term care facilities and programs. Juveniles go through a separate court system, the juvenile court, which sentences or commits juveniles to a certain program or facility.
Once processed in the juvenile court system there are many different pathways for juveniles. Whereas some juveniles are released directly back into the community to undergo community-based rehabilitative programs, some juveniles may pose a greater threat to society and to themselves and therefore are in need of a stay in a supervised juvenile detention center. If a juvenile is sent by the courts to a juvenile detention center there are two types of facilities: secure detention and secure confinement.
Secure detention means that juveniles are held for usually short periods of time in facilities in order to await current trial hearings and further placement decisions. By holding juveniles in secure detention, it ensures appearance in court while also keeping the community safe and risk-free of the juvenile. This type of facility is usually called a "juvenile hall," which is a holding center for juvenile delinquents. On the other hand, secure confinement implies that the juvenile has been committed by the court into the custody of a secure juvenile correctional facility for the duration of a specific program, which can span from a few months to many years.
Juvenile detention is not intended to be punitive. Rather, juveniles held in secure custody usually receive care consistent with the doctrine of parens patriae, i.e., the state as parent. The state or local jurisdiction is usually responsible for providing education, recreation, health, assessment, counseling and other intervention services with the intent of maintaining a youth's well-being during his or her stay in custody.
Generally speaking, secure detention is reserved for juveniles considered to be a threat to public safety or the court process, though in many cases, youths are held for violating a court order. Status offenders, i.e., juveniles charged with running away from home, alcohol possession, and other offenses that are not crimes if committed by adults, may only be held for 24 hours or less, while initial case investigation is completed and other alternatives are arranged.
