This manual, when used with its companion documents, is meant to guide corrections agencies as they develop juvenile aftercare programs to meet the needs of chronic and serious juvenile offenders. In 1987, the Office of Juvenile Justice and Delinquency Prevention (OJJDP) issued a request for proposals concerning intensive community-based aftercare programs (IAP). Research and development, divided into four stages, was designed to: assess current knowledge and programs; develop a promising program mode; disseminate information about the proposed model; and test this model in selected jurisdictions. During the second stage, this policy and procedures manual was developed. Through the use of examples, this manual is designed to provide the reader with a sense of how program elements and components are structured and how they function. These examples are drawn from site visits and other data collection activities, e.g., mail surveys and telephone interviews, conducted during the first stage of this project. As the policies and procedures illustrate, the guiding principles, program elements, and service areas that define the IAP model can be configured and applied in a number of ways. The authors urge that administrative personnel and line staff from each segment of the juvenile justice system and other involved groups participate in the development of the specific form that IAP assumes in that jurisdiction. Eight States were chosen through a competitive process to participate in the training and action planning conferences and implement their own IAP pilots.
