Every year, thousands of young people are released from juvenile correctional institutions nationwide. When released, they face immediate challenges as they attempt to reintegrate into the community where they confront significant barriers to success. Understanding how to support youth when they are returning from a period of confinement requires understanding the harm it inflicts upon a young person during this crucial period of development. While confinement in a juvenile correctional facility can have detrimental impacts, alongside all instances in which a young person is separated from their family and community, it is important to see hope in a justice-involved young person's present situation and future potential. Young people reentering the community have strengths, assets, and aspirations, just like their non-justice-involved peers. Reentry supports that tap those reserves have tremendous potential to make a difference in the long-term outcomes of reentering youth. This practical guide lays out information for practitioners to meet the needs of young people reentering the community, to help remove barriers to success, and to increase young people's chances for more positive outcomes. This guide discusses the philosophical orientation associated with more effective reentry services and provides detailed information on promising supports and programs.
