Despite the many expectations of school counselors in responding effectively to crisis situations, there is a lack of research and comprehensive standards that address best practices for school counselors in terms of preparing for and responding to a school shooting. Using federal guidelines and crisis literature, including studies focused on school counselors' lived experiences of a school shooting, the author offers a research-informed theoretical framework of recommendations at different phases of a school shooting. The framework of recommendations points out probable hindrances to school counselors' decision making. School counselors' awareness of these impediments before experiencing each phase of such a crisis would be of benefit to them. School counselors may also use the framework of recommendations to help them assess their developmental needs in relation to preparing for and responding to a school shooting crisis.
