CDC has been collecting data on school-associated violent deaths since 1992. This data system, which was developed in partnership with the Departments of Education and Justice, monitors school-associated violent deaths at the national level. Information is collected from media databases, police, and school officials. A case is defined as a fatal injury (e.g., homicide or suicide) that occurs (1) on school property; (2) on the way to/from school; or (3) during or on the way to/from a school sponsored event. Only violent deaths associated with U.S. elementary and secondary schools, public and private, are included. Data obtained from this study play an important role in monitoring and assessing national trends in school-associated violent deaths, and help to inform efforts to prevent fatal school violence.
