The "Principles & Standards for Quality Charter School Authorizing," first established in 2004, reflect the lessons learned by experienced authorizers. This foundational resource for National Association of Charter School Authorizers (NACSA) has been used to guide authorizing practices across the country and is referenced in state statutes. It focuses on the ends that authorizers should aim to attain in creating and upholding high expectations for the schools they charter while recognizing there are many means of getting there. The Principles articulate a set of beliefs about quality charter school authorizing. The Standards identify core authorizer responsibilities and describe how the principles are upheld within each responsibility. Consult this resource often as a guide to understanding and fulfilling the critical responsibilities of charter school authorizers. [For the previous edition, see ED580966.]
