As researchers, decision-makers, and practitioners focus on continuous improvement in education, local-level change is gaining importance. Yet, many local school improvement efforts fail to be fully implemented. Even those that are fully implemented often fail to sustain improvements because the schools are embedded in systems that face multiple challenges. Can decision-makers and everyone who is responsible for implementing school improvement efforts come together to build a better, more sustainable approach to local improvement? This toolkit attempts to support such coming together by combining a powerful framework for school turnaround with a focus on the human side of change. The toolkit is built on the intersections between "Leading by Convening" (ED584148), a blueprint for authentic engagement in school improvement developed by 50 national organizations and adopted by the National Center for Systemic Improvement, and the "Four Domains for Rapid School Improvement" (ED584107), a framework developed by the national Center on School Turnaround. In this document, the authors explore the touch points between the "Four Domains for Rapid School Improvement" and "Leading by Convening." The toolkit is organized by the domain areas listed in the "Four Domains" framework. This toolkit emphasizes alignment across the system by focusing first on school-level change, and then back-mapping district and state efforts to create coherent approaches and permit learning across sites and levels. Included in each domain section are pointers to tools from "Leading by Convening," the "Four Domains," and other resources that may be used to build capacity and engage stakeholders, as well as reflection questions drawn from the "Four Domains" framework.
