The American public continues to be concerned about crime in schools and the safety of students. This report is the first to focus on data collected by the 1999 School Crime Supplement (SCS) to the National Crime Victimization Survey. Following the introduction and background, nine chapters report and provide statistics on various facets of school violence and safety: (1) "Students' Reports of Criminal Victimization"; (2) "Students' Reports of Alcohol or Drug Availability at School"; (3) "Students' Reports of the Presence of Street Gangs at School"; (4) "Students' Reports of the Presence of Guns and Weapons at School"; (5) "Students' Reports of Hate-Related Words and Hate-Related Graffiti at School"; (6) "Students' Reports of Bullying at School"; (7) "Students' Avoidance of School, Classes, and Extracurricular Activities"; (8) "Students' Reports of Fear of Victimization at School and Traveling to and from School"; and (9) "Students' Perceptions of School Environment Before and After the Columbine Shootings." A conclusion summarizes the preceding nine chapters. The report ends with tables of estimates and standard errors. Appendices contain technical notes and a description of methodology, references, glossary of terms, and 1995 and 1999 SCS questionnaires. (Contains 82 references, 51 figures, and 46 tables.) (RT)
