School should be a safe place for students to learn and interact, but far too often there are reports of instances in which students end up in harm’s way. From natural disasters to school violence, a crisis can occur at any time, without warning, and in unlikely locations. Although there is no way to prepare for every possible emergency that could occur on a school campus, having a comprehensive emergency plan can help avoid, or prepare for, some of the most common crisis situations. A well-thought-out plan can also provide general guidance for unusual situations that cannot be anticipated. This paper addresses key components that should be considered when preparing and communicating emergency preparedness plans to a school community. It also address types of school emergencies and common scenarios for which school leaders should be prepared.
