H.R. 6809, the Alyssa's Act of 2025, directs the Department of Homeland Security to strengthen school safety through multiple initiatives, including establishing a National School Safety Data Center, developing panic alarm technology for schools, and providing training to schools and first responders on emergency prevention and response. The bill requires that beginning in fiscal year 2026, all federally-funded emergency response maps in schools must be digital, mobile-accessible, real-time updatable, and secure, with data stored within the United States and verified annually for accuracy by local school districts. The legislation also mandates that DHS develop a strategy within one year for distributing compliant maps to federal facilities and emergency responders, and requires annual reporting on state and local school shooting prevention plans, including evaluations of different approaches and associated costs. By establishing these federal standards and requirements, the bill aims to improve coordination and effectiveness of school safety measures across the nation.
