School Survey on Crime and Safety
The School Survey on Crime and Safety (SSOCS) is a sample survey of the nation's public schools designed to provide estimates of school crime, discipline, disorder, programs and policies. SSOCS is administered to public primary, middle, high, and combined school principals in the spring of even-numbered school years. Over 3,000 public school principals are selected to receive the SSOCS questionnaire. The SSOCS sample is large enough to provide national estimates of all public schools, while taking into account a number of factors, including the level of instruction, student enrollment size, and urbanicity.
School principals from a nationally representative stratified random sample of U.S. public schools, including public charter schools but excluding special education schools, vocational schools and alternative schools, home schools, ungraded schools, overseas Department of Defense schools, schools sponsored by the Bureau of Indian Education, and schools in the U.S. outlying areas and Puerto Rico, respond to a mailed questionnaire.
In school year 2007-08, a total of 2560 public schools submitted usable questionnaires, including 618 primary schools, 897 middle schools, 936 high schools, and 109 combined schools. A larger percent of the target sample was allocated to middle and high schools.
