Students Safe at School Act; create to provide procedures for active shooter drills and simulations.

HB 1491, the "Students Safe at School Act," establishes new requirements for active shooter drills and simulations in Mississippi K-12 schools. The bill mandates that student drills must be trauma-informed, age-appropriate, and announced as practice sessions without immediate danger, requiring 24-hour parental notification with opt-out options (no attendance penalty for opting out). It prohibits requiring student participation in active shooter simulations (which mimic real shootings) during regular school hours, bans simulations for students in grades K-8, and allows parental opt-in only for high school students (grades 9-12) during non-school hours. The act also requires post-drill mental health support, safety planning involving student input, and development of school emergency mapping data for law enforcement.
