K-12 School Shootings in Context: New Findings from The American School Shooting Study (TASSS)

August 23, 2023

The American School Shooting Study (TASSS) is an ongoing mixed-method project funded by the National Institute of Justice to catalog US school shootings. It has amassed data based on open sources and other public materials dating back to 1990. This brief presents new insights from TASSS, diving deeper into the database's potential to examine the locations, timing, and student involvement of youth-perpetrated gun violence.

Policy Solutions to Address Mass Shootings

August 1, 2021

In the past decade, mass shootings, particularly those that take place in public areas, have increasingly become part of the national conversation in the United States. Mass public shootings instill widespread fear, in part because of their seeming randomness and unpredictability. Yet when these incidents occur, which has been with somewhat greater frequency and lethality as of late, public calls for policy responses are immediate. In this policy brief, we review efforts to evaluate the effect of gun control measures on mass public shootings, including a discussion of our recently published study on the relationship between state gun laws and the incidence and severity of these shootings. The findings of this work point to gun permits and bans on large-capacity magazines as having promise in reducing (a) mass public shooting rates and (b) mass public shooting victimization, respectively. Interestingly, however, most gun laws that we examined, including assault weapon bans, do not appear to be causally related to the rate of mass public shootings.

Connect & Redirect to Respect: Final Report

January 1, 2019

In 2014 the Chicago Public Schools (CPS) piloted a new approach to reducing violence and promoting safety among CPS students. The Connect & Redirect to Respect (CRR) program aims to keep students safe by using information gathered via social media to identify students engaging in risky behaviors—such as instigating conflict, signaling involvement in a gang, or brandishing a weapon—and connect them to a caring adult who seeks to understand their situation, help them navigate it, and connect them with services intended to keep them safe.This report is an evaluation of the effects of CRR. There is evidence that suggests once the program was fully implemented, students attending participating high schools were at lower risk of being shooting victims; experienced fewer misconduct incidents and out-of-school suspensions; and attended school for several additional days, relative to students in non-participating high schools. These findings suggest that CRR may be a promising approach to improving school and student safety.
