Our Mission


We encourage school personnel, law enforcement officers, mental health professionals, and others involved in school safety to share their averted school violence stories and lessons learned, in order to improve school safety and help prevent future tragedies.

In reviewing cases for inclusion in the database we look for: means, opportunity, motive and intent to carry out targeted school violence. Incidents of violence on school grounds not related to the school (e.g., gang-related violence) and social media threats not deemed credible by law enforcement are excluded from the database.

Sharing your story is an anonymous, secure, non-punitive, and confidential process.
