Building trauma-sensitive schools involves changes to school policy, practice, and culture and requires ongoing efforts to ensure that all students--including students affected by trauma--are experiencing social, emotional, and educational success. School and district leaders play a crucial role in bringing about change. Developing and sharing a vision of trauma sensitivity and the process for achieving it will help to overcome challenges by charting a course of action and maintaining focus and commitment among participants. This action guide is intended to provide school leadership with a roadmap and tools for implementing a trauma-sensitive approach school-wide. It is intended to be used in conjunction with and after viewing the "Leading Trauma-Sensitive Schools" online module, to provide school leadership with a roadmap and tools for implementing a trauma-sensitive approach schoolwide, including recommendations for using various components of the "Trauma-Sensitive Schools Training Package." This guide introduces a multi-phased process for adopting a trauma-sensitive approach. Each phase includes key objectives, activities, resources, and an action planning template. By using the tools and resources provided, schools can develop and implement custom plans for adopting a trauma-sensitive approach school-wide. [For the accompanying Facilitation Guide, see ED595304.
