When a school fails to meet student learning needs year after year—or, in the case of a charter school, fails to meet the terms of its charter contact—closure is sometimes the only responsible intervention. In this report, prepared for the Center on Reinventing Public Education’s National Charter School Research Project, Julie Kowal and Bryan Hassel draw upon interviews with high-quality charter school authorizers and school districts to offer a framework and preliminary lessons for improving the process of school closures. Recommendations include involving key stakeholders early in the closure process, developing clear and objective criteria for selecting schools to be closed, enlisting external evaluators to make tough calls, and creating support structures to help displaced students secure quality alternatives.
