This guide aims to help education professionals reimagine and redefine school safety such that safety is not the absence of a negative but rather the existence of positive elements such as interconnection, belonging, voice, and agency. The guide is intended to support educators and education leaders to create systems of mutual care and shift the paradigm about what safety is and how it is achieved, building safe schools through an "asset frame," which means defining people by their strengths and aspirations rather than their deficits and challenges. Further, working from this paradigm of safety and centering the lived experiences of students and families--especially those who have been kept furthest from institutional power--can be a key component of designing systems that are more equitable and sustainable. This interactive guide pulls from different frameworks and concepts, including "complex adaptive systems," "restorative justice," "co-designing", and "design thinking," to provide educators, school leaders, and district administrators with mindsets, strategies, and grounded examples of what is possible by reimagining school safety.
