Maintaining a safe and supportive learning environment is important for students’ well-being and quality of education. Schools and communities seek the most effective strategies to ensure the safety of students and staff. This literature review discusses the evidence on various school safety practices and programs. Though schools have been quick to implement strategies such as hiring police officers and installing metal detectors, research shows that schools may benefit more from investing in support staff, such as nurses and counselors, and by relying on rehabilitative practices (e.g., social skills training) as opposed to punitive discipline (e.g., suspension and expulsion).
