School Shootings in the United States: 1997–2022

Abstract

School shootings have risen in frequency in the recent 25 years and are now at their highest recorded levels. School mass shootings, although not necessarily increasing in frequency, have become more deadly. This leads to detrimental outcomes for all the nation's youth, not just those who experience school-related gun violence firsthand. School-based interventions can be used to address this public health crisis, and effective approaches such as Multi-Tiered Systems of Supports and services should be used in support of students' mental health and academic and behavioral needs.
