About the Project

The K-12 School Shooting Database research project is a widely inclusive database that documents each and every instance a gun is brandished, is fired, or a bullet hits school property for any reason, regardless of the number of victims, time, day of the week (e.g., planned attack, accidental, domestic violence, gang-related). The database is available for download as a csv file. The School Shooting Database Project is conducted as part of the Advanced Thinking in Homeland Security (HSx) program at the Naval Postgraduate School’s Center for Homeland Defense and Security (CHDS).

The database compiles information from more than 25 different sources including peer-reviewed studies, government reports, mainstream media, non-profits, private websites, blogs, and crowd-sourced lists that have been analyzed, filtered, deconflicted, and cross-referenced. All of the information is based on open-source information and 3rd party reporting.

About the Center for Homeland Defense and Security at the Naval Postgraduate School

The Center for Homeland Defense and Security (CHDS) is located at the Naval Postgraduate School in Monterey, CA. Since 2003, CHDS has conducted a wide range of programs focused on assisting current and emerging leaders in Homeland Defense and Security to develop the policies, strategies, programs and organizational elements needed to defeat terrorism and prepare for and respond to natural disasters and public safety threats across the United States. The programs are developed in partnership with and are sponsored by the National Preparedness Directorate, FEMA.

All CHDS programs are focused on leadership development to transform how public safety officials view an increasingly complex world and homeland security mission.  Through graduate- and executive-level coursework, seminars, and research, homeland security leaders gain the analytic and critical thinking skills and substantive expertise they need to create innovative solutions that address the threats facing the nation and local communities. The programs also prepare leaders to bridge gaps in intergovernmental, interagency and civil-military cooperation by bringing together a diverse range of participants to share perspectives and lay the foundation for long-term homeland security collaboration.
