Crime & Safety Surveys (CSS)


School Crime Supplement (SCS)

The SCS is conducted on a biennial basis as a supplement to the NCVS, which is administered by the Bureau of Justice Statistics (BJS), U.S. Department of Justice, and conducted by the U.S. Census Bureau. The NCVS is an ongoing household survey that gathers information on the criminal victimization of household members age 12 and older. NCES and BJS jointly created the SCS to study the relationship between victimization at school and the school environment.


The SCS is designed to assist policymakers—as well as academic researchers and practitioners at the federal, state, and local levels-in making informed decisions concerning crime in schools. The SCS gathers data from nationally representative samples of students who are between the ages of 12 and 18 and who are enrolled in grades 6–12 in U.S. public or private schools. Prior to 2007, eligible sample members were those who had attended school at any time during the 6 months preceding the interview. In 2007, the questionnaire was changed to include students who attend school at any time during the school year.


The SCS asks students a number of questions about their experiences with, and perceptions of, crime and violence occurring inside their school, on school grounds, on the school bus, and from 2001 onward, going to or from school. The SCS contains questions not included in the NCVS, such as those on preventive measures employed by schools; students’ participation in after-school activities; students’ perceptions of school rules and the enforcement of these rules; the presence of weapons, drugs, alcohol, and gangs in school; student bullying; hate-related incidents; and students’ attitudes related to the fear of victimization at school.


The SCS was conducted in 1989, 1995, 1999, 2001, 2003, 2005, 2007, 2009, 2011, 2013, 2015, 2017, and 2019. COVID-19 has delayed collection for 2021 to 2022, but future administrations are planned at 2-year intervals in odd-numbered years.
