Nashville to install weapon detectors in all public middle schools

Metro Nashville Public Schools will install weapon detectors in all middle schools in the months to come.

The weapons detection system, known as Evolv, is already in place at all MNPS high schools.

Weapon detection scanners are coming to all public middle school campuses in Nashville.

The Metro Nashville Public Schools board unanimously approved a $1.2 million expansion to an existing contract with System Integrations Inc. to install the scanners. The money draws from a state school safety grant. The system, known as Evolv, uses artificial intelligence to detect concealed weapons as people enter a school and is more specialized than a traditional metal detector. It includes scanner panels similar to what patrons at a stadium or arena may pass through before an event.
