December 6, 2021 – For decades, school leaders, law enforcement officials, parents, students, and communities that have experienced tragic incidents of targeted violence in schools have provided insights, after-action reports, and “lessons learned” from their experiences. Government agencies, non-profit organizations, task forces, and researchers have convened to identify commonalities among these violent acts to develop best practices to prevent, respond to, and recover from violence in schools. After decades of research and advocacy for safer schools, acts of violence continue to go unmitigated despite an abundance of guidance on the subject.
