This is the final report on the process evaluation of the aftercare services program of the Pennsylvania Bureau of Juvenile Justice Services (BJJS), prepared by the National Center for Juvenile Justice (NCJJ) for the Pennsylvania Commission on Crime and Delinquency. NCJJ evaluated the design and implementation of the new BJJS program for aftercare service delivery, transformed in January 2005 from a treatment model to a case management model. The new model provides services at disposition, an earlier stage than the norm. Juveniles progress through their own individualized service plans, which are developed taking into account their own and their family’s needs, as well as community resources available to them. The new model requires collaboration among agencies that previously functioned independently. Chapters in this full report include: Executive Summary, Program Overview, Evaluation Methods, Organizational Capacity, Program Planning and Design, Structure and Operations, Information Management, and Program Enhancements and Standards for Aftercare. Appended are 15 attachments, including survey and questionnaire forms, various assessment forms, sample aftercare plan, proposed training, administrative procedures, and individual case record review.
