The Center on School Turnaround at WestEd has developed a framework to assist states, districts, and schools in leading and managing rapid improvement efforts. The framework shares, in practical language, the critical practices of successful school turnaround in four domains, or areas of focus, that research and experience suggest are central to rapid and significant improvement: turnaround leadership, talent development, instructional transformation, and culture shift. At a more fine-grained level, the framework then offers examples of how each practice would be put into action at each level of the system. [Contributing writers were Coby V.
