This is the 23rd edition of Indicators of School Crime and Safety, a joint effort of the Bureau of Justice Statistics (BJS) and the National Center for Education Statistics (NCES). This report provides summary statistics to inform the nation about current aspects of crime and safety in schools. This report covers a variety of topics on school crime and safety. It first examines different types of student victimization, including violent deaths and school shootings, nonfatal criminal victimization, and bullying victimization. Then, the report presents data on measures of school conditions--such as gangs, hate-related speech, possession of weapons, and use and availability of illegal drugs--as well as data that reflect student perceptions about their personal safety at school. This report wraps up the discussion on crime and safety issues at the elementary and secondary level by examining the percentages of teachers who reported having been threatened or attacked by their students. It has the most recent available data, compiled from a number of statistical data sources supported by the federal government. [For the 2019 report, see ED606370.]
