Last fall, researchers at Bellwether Education Partners began research on how standard authorizing practices could discourage or disadvantage charter schools with nontraditional models, such as dual language immersion, Montessori, and competency-based education models. Throughout the course of their research, the authors spoke to dozens of school leaders and authorizers to better understand how they work to ensure quality even when a school model looks substantially different than what is typical. While not the intent of the research, much of what was learned can apply to the charter school sector today. Specifically, authorizers and school leaders can work together to respond effectively to COVID-19--by building their capacity, communicating with stakeholders, codifying their model, and quantifying their impact. This toolkit includes strategies and recommendations for authorizers and school leaders as they navigate the coming months and years. [For the accompanying policy report, see ED610381.
