This report, the fourth in a series of annual reports on school crime, presents the latest available data on school crime and student safety. National indicators affirm that the levels of crime in school have continued to decline, that acts that promote fear and detract from learning are decreasing, and that students feel safer in school than they did a few years ago. Despite declining rates, students ages 12 through 18 were victims of about 2.5 million crimes of violence or theft at school in 1999. Violence, theft, bullying, drugs, and firearms still remain problems in many schools throughout the country. There are five sections to the report: (1) "Violent Deaths at School"; (2) "Nonfatal Student Victimization--Student Reports"; (3) "Violence and Crime at School--Public School Principal/Disciplinarian Reports"; (4) "Nonfatal Teacher Victimization at School--Teacher Reports"; and (5) "School Environment." Each section contains a set of indicators that, taken together, describe a distinct aspect of school crime and safety. This report uses a variety of independent data sources from federal departments and agencies including the Bureau of Justice Statistics, the National Center for Education Statistics, and the Centers for Disease Control and Prevention. Each data source has an independent sample design, data-collection method, and questionnaire design, all of which may be influenced by the unique perspective of the primary funding agency. Three appendices list school-safety practices and policies related to safety and discipline, technical notes, and a glossary of terms. (Contains 66 tables and 19 figures.) (MLF)
