This report presents findings on crime and violence in U.S. public schools, using data from the 2005-06 School Survey on Crime and Safety (SSOCS:2006). Developed by the National Center for Education Statistics (NCES) and supported by the Office of Safe and Drug-Free Schools of the U.S. Department of Education, SSOCS asks public school principals about the frequency of incidents, such as physical attacks, robberies, and thefts in their schools. Portions of this survey also focus on school programs, disciplinary actions, and the policies implemented to prevent and reduce crime in schools. Because the purpose of this report is to introduce new NCES data through the presentation of tables containing descriptive information, only selected findings are presented. These findings have been chosen to demonstrate the range of information available when using SSOCS:2006 data rather than to discuss all of the observed differences. The following are appended: (1) Standard Error Tables; (2) Methodology and Technical Notes; (3) Description of Variables; and (4) 2005-06 School Survey on Crime and Safety Questionnaire. (Contains 21 tables and 8 footnotes.)
