U.S. teachers' reports of physical security measures at school 2022, by demographic
According to a survey conducted in 2022, the majority of public K-12 teachers reported that their school had procedures to keep exterior doors locked during school hours, and had locks or other measures for interior doors, at 91 percent and 90 percent respectively. However, only eight percent indicated that their schools had metal detectors or other screening at school entrances in place. In comparison, teachers in higher-poverty schools, in schools located in urban areas, and in schools which primarily served students of color were more likely to report that their schools had metal detectors or other screening in place.
