While schools are safer today than in years past, one act of school violence is one too many. Recent reports have conveyed the importance of schools developing and implementing protocols and procedures to prevent or mitigate school violence. To assist with this task, this article addresses behavioral threat assessment and management (BTAM) in the K-12 school setting and the school psychologist's role in risk and threat assessment. Best practices in establishing a K-12 behavioral threat assessment and management process, including the assessment of risk factors and warning signs, identification of concerns, and follow-up interventions and monitoring are discussed. Ethical and legal considerations are also reviewed.
