In 2013, national education groups representing principals, school-employed mental health professionals, and school resource officers developed "A Framework for Safe and Successful Schools" (ED612657) to provide a common set of recommendations for policies and practices that create and sustain safe, supportive learning environments. The goal was, and is, to reinforce the interdisciplinary, collaborative, and cohesive approach required to improve school climate, implement multitiered systems of support, advance positive discipline practices, and increase access to the mental and behavioral health services necessary to meet the needs of all children and youth. This supplemental guidance offers additional considerations and action steps to help school leaders implement comprehensive school safety efforts as outlined in the Framework. In addition to the Framework itself, this guidance can be used in conjunction with the 2017 "Policy Recommendations for Implementing the Framework" (ED612660) and "Assessing the Safety of the School Environment Using the Framework" (ED612658) as well as the resources provided in the current Framework.
