It is of vital importance that children are educated in a safe environment. Every school needs to have a well-developed crisis management document containing plans for prevention, intervention, and postvention. We developed the Comprehensive Crisis Plan Checklist (CCPC) to serve as a valuable tool that can be used to assist practitioners with evaluation of their school crisis management plans. To use the CCPC, school personnel should match the items on the checklist to elements in their developing or existing crisis plan to determine missing elements. By comparing a school or district crisis plan to the CCPC, practitioners or school personnel will be able to determine strengths and weaknesses of the plan as well as provide feedback for making their plans more complete and comprehensive. In this study, we describe the development of the CCPC and report on reliability data using this checklist.
