Written to help school administrators and community leaders, this pamphlet discusses school vandalism and ways to prevent it. The first sections highlight the physical, financial, and social costs of vandalism and present a profile of the typical vandal--a young teenage boy. The following sections review the psychological reasons for vandalism, which the authors say are not well understood, and enumerate the characteristics of schools, administrators, teachers, and student-school relations that accompany vandalism. Next, a "primer" on vandalism prevention first notes the inconsistent effectiveness of increased security measures and then recommends techniques for making schools less vulnerable and attractive to attack. Ways suggested to reduce vulnerability include occupying, watching, and controlling access to the school and designing schools with vandalism in mind. Techniques for reducing attractiveness as a target include revising curriculums, changing administrative policy and organizational structure, and involving students, parents, and the community. The final section gives five suggestions for immediate responses to vandalism, including quick repair, formal recordkeeping, and the seeking of restitution. A brief bibliography is appended. (RW)
