To support the overall safety and well-being of school communities, the National Association for Behavioral Intervention and Threat Assessment (NABITA) provides school-based behavioral threat assessment and management standards as proactive best practices for K-12 schools and districts. To that end, this newly revised whitepaper, NABITA Standards for School-Based Behavioral Threat Assessment and Management in K-12 Education (NABITA BTAM Standards for K-12), includes new standards addressing emerging needs for schools, such as recommended practices for receiving referrals of concerning behavior, addressing cases comprehensively and holistically, and ensuring program effectiveness.
