U.S. public school students increasingly attend schools with sworn law enforcement officers present. Yet little is known about how these school resource officers (SROs) affect school environments or student outcomes. Our study uses a fuzzy regression discontinuity (RD) design with national school-level data from 2014 to 2018 to estimate the impacts of SRO placement. We construct this discontinuity based on the application scores for federal school-based policing grants of linked police agencies. We find that SROs effectively reduce some forms of violence in schools, but do not prevent gun-related incidents. We also find that SROs intensify the use of suspension, expulsion, police referral, and arrest of students. These increases in disciplinary and police actions are consistently largest for Black students, male students, and students with disabilities.''

The American School Shooting Study (TASSS) is an ongoing mixedmethod 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.

Although statistically rare, fatal and nonfatal shootings in the United States at elementary, middle, and secondary schools remain important crime problems with significant public policy implications. Indeed, the impact of such violence exceeds the devastating fatalities and immense sorrow that survivors, families, and communities experience. Even one gunshot fired at a school can subject numerous individuals to the traumas of gun violence.1 Recent polls indicate that school shootings can also sway broader public views on crime, including attitudes toward violence reduction.2 As a result, school shootings have become a focal point of US politics, sparking crucial debates on the most effective strategies for preventing and responding to gun violence, both inside and outside K-12 schools.
