Schools should be safe places for young people, educators, school staff, and community members, and policies and practices can help create learning environments where kids thrive. Gun violence in U.S. schools has prompted calls for increased school safety measures; however, which policies contribute to safe school environments is often a topic of debate. How can schools create safe environments while also fostering welcoming, equitable school climates that support growth, learning, and community? To help Colorado policymakers and school communities answer this question, the Colorado Children's Campaign has identified and compiled research on strategies that are supported by strong evidence. While school safety can be defined broadly as freedom from physical, emotional, and psychological violence, this brief focuses on promoting freedom from bodily harm in a school setting. Strategies that support students' well-being and prevent bullying, fighting, the use of weapons, and other types of violence can contribute to reducing harm.
