Schools and school districts should keep detailed records on incidents of violence and vandalism so as to plan for school safety and security, plan policies and programs for better student control and the improvement of attitudes, evaluate the success of efforts to reduce violence and vandalism, and increase the accountability of the public schools to the public. The first model described, which is used in the Broward County School District, Ft. Lauderdale, Fla, includes a detailing of the content of the reports and the collection, summarization, and subsequent use of the data. The second model (Washoe County School District, Reno, Nev.) presents school board regulations on what must be reported, by whom, and to whom and describes how the reporting system operates. Also included are the district's incident reporting form and a flow chart depicting how discipline reports work in tandem with reporting criminal incidents. The third model (San Diego public schools) emphasizes the usefulness of individual school security plans and the responsibilities of teachers, custodians, and principals for reporting. The fourth model (Shawnee Mission Public Schools, Shawnee Mission, Kan.) describes how a committee, whose functions include both due process hearings and evaluation for special education, develops and uses incident reports to analyze student problems and develop solutions. The final model (New York City Public Schools) describes what will be reported, by whom, to whom, when, and how. A checklist for assessing a school reporting system is also included. Short reports are presented from various States.
