The Big Five

Immediate Action Response: The Big Five

San Mateo County's Coalition for Safe Schools and Communities is a collaborative, multi-agency group that was formed in 2013, following the fatal shooting of 26 students and staff at Sandy Hook Elementary School in Newtown, Connecticut.

The mission of the Coalition for Safe Schools and Communities is to identify and address safety needs of county youth, to work across agencies to implement best practices in emergency response and mental health, and to support with a legal framework for lawful information sharing, using a common language.

Through this collaborative process, the Coalition produced the Big Five, a common emergency plan adopted by all San Mateo County School Districts and law enforcement agencies.

The Big Five protocol supports high quality training for school staff and community members and ensures clear channels of communications with schools, first responders, parents and community members should an emergency occur.
