The authority to operate a charter school is granted through a limited-term, renewable contract. Contract renewal is not automatic--it must be earned through strong academic results and operational effectiveness. Good schools should be cultivated and poor ones shut down. This is one of the definitive functions of a charter school authorizer. This policy guide discusses the following: (1) Background on Charter School Renewal; (2) Key Considerations for Policymakers Committed to Supporting Quality Charter School Renewal; (3) Recommendations and Best Practices for State Policy on Charter School Renewal; and (4) Resources and Further Analysis. (Contains 5 endnotes and 11 resources.)
