This report analyzes data from the 2000 School Survey on Crime and Safety presented in "Violence in U.S. Public Schools: 2000 School Survey on Crime and Safety. Statistical Analysis Report." Principals at 3,314 nationally-representative K-12 schools described incidents of crime and violence, disciplinary problems and actions, use of security measures, safety policies and practices, violence prevention programs and activities, and school characteristics. Overall, 71 percent of schools experienced at least one violent incident, 20 percent experienced at least one seriously violent incident, 36 percent reported at least one violent incident to the police, and 15 percent reported at least one seriously violent incident to the police. Only 6 out of 17 school characteristics accounted for the prevalence of violence (demographics, urbanicity, academic achievement, number of classroom changes during the school day, number of schoolwide disruptions, and number of discipline problems). Five characteristics related to serious violence (enrollment size, percent of males, number of schoolwide disruptions, number of serious discipline problems, and urbanicity). Characteristics of schools with high violence included enrollment size, urbanicity, neighborhood crime, number of classroom changes, number of serious discipline problems, and number of schoolwide disruptions. Characteristics of schools with high serious violence included enrollment size, students below the 15th percentile on standardized tests, student-teacher ratio, number of serious discipline problems, number of students transferring from the school, and number of schoolwide disruptions.
