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.
