Collaborations between law enforcement agencies and elementary and secondary schools focus on the provision of education to students, the safety and security of school property, and public relations efforts aimed at changing youths' attitudes toward the police both inside and outside of schools. The use of police officers in school settings originally emerged from a focus on addressing youth crime and violence. Current funding trends regarding police-school collaborations support the view that concern regarding youth crime and violence in and around school property is a key reason for establishing and maintaining such collaborations. This study examines the role of police officers in elementary and secondary schools and the similarities between police officers' roles and school social work practice and provides suggestions for school social workers regarding the development and implementation of collaborations with police officers to address youth crime and violence in schools.
