This report has been revised to best highlight information from the new Student Safety Data System for the 2017-18 school year. The New Jersey Department of Education (Department) migrated to a new reporting system, the Student Safety Data System (SSDS), which includes improved definitions, new reporting fields, and updated guidance for reporting incidents. As such, comparing this year's report to previous years' data can lead to inaccurate conclusions in many reporting categories, and this report should be considered a baseline year. This information is provided by New Jersey public schools on disciplinary infractions and their consequences by the New Jersey Department of Education to the Governor and Legislature to fulfill the requirements of the "Public School Safety Law N.J.S.A." 18A:17-46 through 48. Districts are encouraged to review their incidents in comparison to state-level results and consider whether proactive steps are needed to improve school climate and student safety. Although the report has been revised to best highlight information from the new data system, the SSDS continues collection of incidents of violence, vandalism, weapons, substance use, and harassment, intimidation and bullying (HIB), as well as HIB trainings and programs. In addition, the system now collects details on all allegations of HIB, along with all student suspensions and other removals from school, as well as reports to the police and arrests. New features and data reporting changes in the SSDS were developed to capture details required for state and federal data collection, including School Performance requirements of the Every Student Succeeds Act and "N.J.S.A." 18A:7E-3 and the federal Civil Rights Data Collection. Changes were also made to make reporting easier for schools and districts and to improve data quality.
