New or enhanced non-secure alternatives to detention programs increase the options available for arrested youth by providing supervision, structure and accountability. Detention alternative programs target only those youth who would otherwise be detained, and typically include: electronic monitoring, house arrest, community monitoring, day or evening reporting centers, and shelter beds for youth who cannot return home.The most effective juvenile justice systems have a program continuum that both responds to the legal status of youth and ensures that they can also be safely supervised in the community. Pre-adjudicated youth, programming should be linked to their level of risk of Failure-to-Appear or re-arrest; post-adjudication programming should be linked to the dispositional purposes the court seeks to accomplish (i.e., sanctions or rehabilitative goals). Programs should also be able to respond to compliance failures by increasing contact and case management activities instead of automatically terminating participation for noncompliance. Whether pre-adjudication or post-adjudication, ATDs should be grounded in an understanding of adolescent development and behavior, and program activities should reflect youths’ needs, cultures and traditions.
