1Schools that had multiple shootings in a single year are counted only once in that year's total, and schools that had shootings in multiple years are counted only once in the total across years.

2Includes schools for which school-level information was unknown or unspecified as well as those whose school level was "other."

NOTE: "School shootings" include all incidents in which a gun is brandished or fired or a bullet hits school property for any reason, regardless of the number of victims (including zero), time, day of the week, or reason (e.g., planned attack, accidental, domestic violence, gang-related). Deaths and injuries include both shooters and victims. This table was created using a database that aims to compile information on school shootings from publicly available sources into a single comprehensive resource. For information on database methodology, see K-12 School Shooting Database: Research Methodology (https://www.chds.us/ssdb/resources/uploads/2020/09/CHDS-K12-SSDB-Research-Methods-Sept-2020.pdf). Due to adjustments made to the learning mode (in-person, remote, or hybrid) during the coronavirus pandemic, caution should be used when comparing data since 2019-20 with those from earlier years. Some data have been revised from previously published figures.
