Nationally, the number of charter schools opening and the enrollment size at charters is on the rise. But what happens when charter schools are low performing? For most charter schools and their authorizers, closing low-performing schools seems inevitable. However, school closures have dramatic impacts on students, families, and communities -- impacts that extend beyond just student learning outcomes. There is another option: comprehensive improvement, or what is known as "turnaround." Perry Street Preparatory Charter School was given that option. This report details their five year journey from being one of the lowest performing schools in Washington, DC to one of the highest performing. Perry Street is one of the few charter schools to conduct a comprehensive improvement effort and do so independent of another operator. Instead, Perry Street's board chose to work with a third-party turnaround partner to initiate, support and build capacity to sustain change. This report is designed to share Perry Street's story of comprehensive improvement, written intentionally for school leaders, board members, and authorizers. The report shares what conditions need to be in place for turnaround to succeed--to capture one charter school's turnaround framework, process, and best practices to benefit those going through turnaround, supporting turnaround efforts, or determining whether schools would be good candidates of turnaround.
