After a dozen years of work in the field of charter school authorizing, NACSA has amassed the national repository of cutting edge authorizing practice. In order to maximize the application and availability of this knowledge base, we published a series of policy guides to the eight critical elements of the charter school authorizing life cycle. Based on practices developed in states and districts across the country, this series represents an opportunity for states to learn from each other, to share knowledge gained of experience, and to enhance their ability to cross-pollinate the best practices in charter school authorizing.
