The objective of this study was to identify, describe, and appraise existing behavior-oriented, vandalism-prevention programs using a case-study approach. This report summarizes an investigation of three programs in Ontario (Canada): Project PRIDE (Pupils Responsible in Determining their own Environment); Operation Aware; and a Diversion program. The general research methods are outlined and detailed descriptions and assessment of each program are given. Project PRIDE was implemented in a school system composed of 45 elementary schools and 10 secondary schools. The major component of the project is a financial incentive in which an account is established for each school on the basis of student enrollment. Costs incurred as a result of vandalism are subtracted from the fund and the balance given to the student council at the end of the school year. Operation Aware is an awareness program designed to teach grade 5 and 6 students what to expect from their peers as they mature and how to cope with negative peer influence. Five Ontario school boards adopted Operation Aware as a pilot program. The Diversion program's purpose is to evaluate young offenders and postpone or prevent their entry into the formal criminal justice system. The Waterloo County Board of Education has been involved in eight Diversion cases. (Author/MLF)
