School Security Enhancement Act

This bill amends the Elementary and Secondary Education Act to allow local schools to use existing federal funds for specific security improvements. It directly affects schools receiving ESEA funds by expanding eligible uses to include measures like metal detectors, bullet-resistant windows, crisis notification systems, and infrastructure for controlled access. Key provisions require security measures to have "evidence-based effectiveness" where available, while explicitly prohibiting the use of funds for firearms or firearm training. The bill does not override other laws permitting firearms but clarifies that security enhancements must focus on non-firearm solutions.
