This report summarizes the state of knowledge about children and youth with disabilities at risk of delinquency or already involved with the juvenile justice system. It reviews the existing research as well as perspectives of service providers, administrators, policy makers, and advocates. Following an executive summary and introductory chapter, chapters address the following topics: (1) background; (2) data and methodology; (3) current laws and philosophical framework; (4) disability, delinquency, and juvenile justice; (5) risk and protective factors associated with juvenile delinquency; (6) program and policy trends; (7) promising practices and criteria/measures of effectiveness; (8) implementation of disability law and programs (barriers and facilitators); and (9) recommendations. Recommendations urge identifying a range of strategies to promote compliance with federal disability law for at-risk children and youth; increasing funding and/or resources to schools and the juvenile justice system; designating a single federal agency whose sole focus is the needs of youth with disabilities entering the juvenile justice system; conducting research on the true prevalence of youth with disabilities across all stages of the juvenile justice system; and conducting an assessment to determine what programs and policies are most effective in schools, communities, and the juvenile justice system. Five appendices provide additional detail and list resources. (Contains approximately 200 references.) (DB)
