This paper is intended to help program developers to initiate or refine school-based, self-contained delinquency prevention programs. These programs are limited, short-term efforts to minimize delinquent behavior among youth by creating school situations in which the factors that contribute to delinquent behavior are reduced. Designed as an accompanying document to a monograph that reviews theory, research, principles, strategies, and options concerning delinquency prevention, the paper describes desirable program features and suggests activities through which those strategies and principles can be applied. Following an introductory section, chapter 2 presents an overview of self-contained delinquency prevention programs and their benefits; compares such programs with larger scale efforts for selective organizational change; and explains why the focus is on schools. Chapter 3 describes program features in detail, and refers to the principles and strategies upon which they are based. The features discussed include content and activities, participants, program routine, setting, and evaluation. Finally, chapter 4 explains how the principles and strategies apply to tasks and activities in a sequence of implementation steps, and contains recommendations for initially assessing prospects for a program, obtaining support, and developing a plan of action.
