This study examines the relationship between school violence and involvement of community organizations in school safety planning. The study is a secondary analysis of data from the School Survey on Crime and Safety 2003-2004 (U.S. Department of Education, Institute of Education Sciences, 2006). This survey collects data on crime and safety from principals and school administrators in public schools in the United States. The study used a stratified sample of 3,743 regular public schools that were drawn from the Common Core of Data Public School Universe file. Stratified sampling was used to ensure that the selection of schools contained an equivalent percentage most representative of public schools across the nation. Of 3,743 surveys distributed, 2,772 completed surveys were received, yielding a 77.2 percent response rate. Eight variables from this data set were used in measuring the level of community involvement in school safety plans. When looking at community organizations' involvement in school safety planning and the impact these organizations have on the number of serious violent incidents in school, only the involvement of law enforcement agencies predicted with statistical significance rates of serious violent incidents reported in the school. Involvement of law enforcement was related to a reduced risk of violent incidents. (Contains 3 tables.)
