"It has been estimated that nearly 250,000 youth under age 18 end up in the adult criminal justice system every year. However, little attention has been directed to how adult corrections systems are managing the youth offenders that end up in jails, prisons and under community supervision. To address this information gap, the National Institute of Corrections (NIC) convened three dozen juvenile justice and adult corrections experts on June 18th, 2010, to consider some of the known issues, impacts and opportunities that face corrections systems as they work to safely and effectively rehabilitate thousands of youth offenders in the nations' jails, prisons, probation and parole systems. This monograph presents the key findings identified during this convening of experts." Six sections comprise this publication: executive summary; what is known about the issue of juveniles in the adult corrections systems, and where there are gaps in data collection and information; what the issues, impacts and options are facing public safety systems when youth are awaiting trial on adult charges; when youth are convicted, and committed to the adult system; when youth who convicted in adult court are on probation or parole; and conclusion--corrections and the entire public safety system needs to focus on the successful strategies to curb delinquency, and positive youth development. The "Summary of Options for Federal, State, and Local Policymakers to Consider" is appended.
