Student victimization and school violence have been an ongoing cause of national concern, resulting in a concerted effort among educators, administrators, parents, and policymakers to determine the gravity of the issue and consider approaches to crime prevention. This Statistics in Brief presents estimates of student criminal victimization at school by selected student characteristics and school conditions, reports of bullying victimization and other indicators of school disorder, school security measures, and student avoidance behavior. To assist policymakers, researchers, and practitioners in making informed decisions concerning crime in schools, the National Center for Education Statistics (NCES) collects data on student criminal victimization through its sponsorship of the School Crime Supplement (SCS) to the National Crime Victimization Survey (NCVS). The U.S. Department of Justice, Bureau of Justice Statistics (BJS), administers both surveys. This report uses data from the 2015 NCVS Basic Screen Questionnaire (NCVS-1), NCVS Crime Incident Report (NCVS-2), and SCS.1 The NCVS is the nation's primary source of information on criminal victimization and the victims of crime. The SCS collects additional national-level information from students in NCVS survey households, including questions about their experiences with and perceptions of crime and violence occurring at their school, on school grounds, on the school bus, and going to or from school. The SCS contains questions in areas not included in the NCVS, such as: (1) student reports of being bullied at school; (2) the presence of weapons, gangs, hate-related words, and graffiti in school; (3) the availability of drugs and alcohol in school; and (4) students' attitudes related to fear of victimization and avoidance behavior at school.
