For over 20 years, the U.S. Secret Service National Threat Assessment Center (NTAC) has conducted research on the thinking and behaviors of those who commit acts of targeted school violence in order to prevent future acts from occurring. Key findings from this research indicate that establishing multidisciplinary threat assessment teams and encouraging school communities to report concerning behaviors are critical steps in the prevention of targeted violence. This presentation will highlight past incidents and include relevant findings and recommendations from NTAC’s latest research publications on averted school attacks at K-12 schools in the United States. It will also focus on how communities can use a multidisciplinary approach to identify, assess, and intervene with students exhibiting concerning or threatening behaviors as early as possible.
