The authors interviewed a school counselor to determine her response to an armed hostage event in a classroom. They found that her primary interventions took place after the perpetrator had been taken into custody, through counseling students who had been in the room, contacting professionals from the school district and the local mental health facility for help, and coordinating these other professionals. Results are presented in light of the crisis intervention literature. Finally, implications for professional school counselors are discussed. (Contains 1 table.)
