The Comprehensive School Threat Assessment Guidelines model (originally Virginia School Threat Assessment Guidelines), developed by Dr. Dewey Cornell in 2001, focuses on a multidisciplinary team approach, using a decision tree process, to discern and respond to threats of violence within schools. CSTAG became nationally recognized as an evidence-based threat assessment program in 2013 and has demonstrated effectiveness through controlled studies.
