Report

Through the Averted School Violence (ASV) project, the National Policing Institute has developed a database to collect, analyze, and publish incidents of averted and completed acts of school violence that have occurred since the attack on Columbine High School in 1999. This report draws from the ASV database to analyze 51 completed and 51 averted incidents of school violence to help further our understanding of them, as well as provide important lessons about how school violence can be prevented. The 51 completed attacks were chosen as a data set that can be compared to another chosen data set of 51 averted incidents of school violence that occurred since the attack at Columbine. Information collected on each averted and completed incident consisted of the following categories as displayed in the database: basic information, school information, event information, suspect information, and assessment. The assessment discusses lessons learned from the attack or planned attack and recommendations on how to prevent future attacks or planned attacks of a similar nature.
