This report presents findings from the Principal/School Disciplinarian Survey on School Violence commissioned by NCES to obtain current data on school violence and other discipline issues in our nation's public elementary and secondary schools. The survey requested information about 1) the actual number of specific crimes that had occurred at school during the 1996-97 academic year; 2) principals' perceptions about the seriousness of a variety of discipline issues at their schools; 3) the types of disciplinary actions schools took against students for some serious violations; and 4) the kinds of security measures and violence prevention programs that were in place in public schools.
