You may notice more weapons detection systems at Metro Nashville Public Schools this fall. Here’s where

Metro Nashville Public Schools (MNPS) has installed Evolv weapons detection systems in all high schools and middle schools by May 14, 2026, following the 2025 Antioch High School shooting. The systems have detected six guns since their rollout, and the district emphasizes a multi-layered approach to safety, including school resource officers and AI camera monitoring. No changes are proposed for elementary schools, though Metro Nashville Police are expanding school resource officer programs as staffing allows.
