Conducted between 1988 and 1993, project assessment efforts focused on three key activities: (1) comprehensive review of the literature on critical issues in the design and operation of intensive aftercare programs (IAP's); (2) survey of innovative and promising programs; and (3) analysis of intensive aftercare approaches and practices at selected sites. It was found that major innovations in intensive juvenile aftercare were largely concentrated in a small number of jurisdictions where the momentum for change in parole philosophies and practices led to experimentation and reform. Most jurisdictions adopted risk and need assessment procedures to guide decisionmaking for surveillance, supervision, treatment, and service provision. Intensive intervention was based on a blend of social control and treatment-service provision strategies. IAP's in California, Utah, Illinois, Kansas, and Texas are described. An IAP model is proposed that combines salient features of the most innovative strategies and that aims to transition high-risk juvenile parolees back into the community. 33 references
