Taking action now can save lives, prevent injury, and minimize property damage in the moments of a crisis. If you do not have a crisis plan in place, it is time to develop one. If you have one, review, practice, and update your plan. This brochure is designed to assist schools and communities in either situation. Although every school's needs and circumstances are different, these checklists provide general guidance that can be adapted as appropriate to each district's or school's circumstances.
