Preventing school shootings is a matter of conducting thorough, ongoing assessments of potential perpetrators. This is generally done in schools by a threat assessment team comprised of individuals in several roles and positions, including psychologists. This article addresses the importance of access to information and information exchange, warning signs of potential violence, elements of a comprehensive threat assessment (including motive, means, and opportunity), and the role of life stressors that contribute to desperation and rage, and three psychological types of school shooters.
