School Threat Assessment Toolkit

The School Threat Assessment Toolkit is designed to aid schools in employing behavioral threat assessment (TA) and management as part of a comprehensive violence prevention strategy. Authored primarily by Dewey Cornell and Jennifer Maeng, and with input from school safety leaders, experts, government agencies, and the National Center for School Safety, the toolkit offers guidance on training, implementation, and assessment of school TA teams. It aims to ensure fidelity to student rights while providing practical tools like documents, forms, videos, and additional resources to support schools’ efforts.
