Enhancing School Safety Using a Threat Assessment Model: An Operational Guide for Preventing Targeted School Violence [open pdf - 1MB]
"When incidents of school violence occur, they leave a profound and lasting impact on the school, the community, and our nation as a whole. Ensuring safe environments for elementary and secondary school students, educators, administrators, and others is essential. This operational guide was developed to provide fundamental direction on how to prevent incidents of targeted school violence, that is, when a student specifically selects a school or a member of the school community for harm. The content in this guide is based on information developed by the U.S. Secret Service, Protective Intelligence and Assessment Division, National Threat Assessment Center (NTAC)."
