This report analyzes the national 2000 School Survey on Crime and Safety (SSOCS), which surveyed 2,270 regular public K-12 schools regarding school crime and safety. The study asked school principals about the characteristics of school policies, school violence prevention programs and practices, violent deaths at school and elsewhere, frequency of crime and violence, disciplinary problems and actions, and other school characteristics associated with school crime. Results indicated that 71 percent of the schools experienced at least one violent incident in 1999-00 (including rape, sexual battery other than rape, physical attacks or fights with and without a weapon, threats of physical attack with and without a weapon, and robbery with and without a weapon). Overall, approximately 1,466,000 such incidents were reported. One or more serious violent incidents occurred in 20 percent of all public schools. Secondary schools, city schools, schools with the lowest achievement, and schools where students had a larger number of classroom changes were the most likely to report violent incidents. About 7 percent of public schools accounted for 50 percent of the total violent incidents. Tables of estimates, tables of standard errors, figures, and an appendix (SSOCS Questionnaire) comprise the bulk of the document. (Contains 37 references.) (SM)
