School resource officers (SROs) are being increasingly employed in schools to respond to incidents of school violence and to help address safety concerns among students and staff. While previous research on school safety and crisis teams has examined the role of school mental health professionals' and administrators, fewer studies have evaluated the role of the SRO. The current study examined differences between SROs, school administrators, and school mental health professionals (i.e., school psychologists, school counselors, social workers) regarding experiences with crisis events, as well as perceived effectiveness of crisis prevention and response strategies. The most common crisis events across professionals included student assaults, drug offenses, and mandated child abuse and neglect reporting. While SROs and school mental health professionals had similar ratings of school safety strategies, school administrators had less effective appraisals of crisis response plans and crisis postvention activities. Implications for practice and future directions for research are reviewed.
