Shooting incidents at kindergarten through grade 12 (K-12) schools in the United States have sparked calls to increase security or adopt altogether new approaches to school safety. These approaches include allowing teachers or staff to carry firearms in some schools. To learn what teachers across the United States think about school safety generally and about specific proposals to enhance safety in schools, such as teacher-carry policies, RAND researchers administered a survey to a randomly sampled set of 973 K-12 teachers using the American Teacher Panel. The survey focused on teachers' views of safety in their schools, including their main safety concerns, perceptions of security measures in place, the effect of those measures on school climate, and whether they were concerned for their own safety and that of their students. On the specific issue of firearms in school, the survey asked whether allowing teachers to carry firearms would make schools more or less safe and whether teachers would personally carry a firearm if given the choice to do so. Findings note that teachers, like the U.S. population as a whole, are divided about armed teachers at school: Fifty-four percent of respondents reported believing that teachers carrying firearms will make schools less safe, 20 percent reported believing that it will make schools safer, and the final 26 percent reported feeling that it would make schools neither more nor less safe.
