Prevention and control strategies include police-taught education programs designed to provide information and build friendship between police and students, onsite presence and police liaison programs, and police response strategies focusing on particular problems or events. Approaches used by educators include working with police, data collection and program planning, internal school security and safety programs, and child-centered intervention approaches. Two national approaches have used community cooperation or information as a means to motivate planning to improve the learning environment and the management of disruptive youth. In general, police-originated programs tend to be more education oriented, while school-oriented programs tend to be more security oriented. A new, promising approach, the safer school model, combines key elements of both disciplines in a school team approach that involves data collection and analysis and data-based planning and problemsolving. 49 references.
