Once the local board of education has approved the charter, the parties (the charter school and the authorizer) have ninety days to finalize the charter contract. It is imperative that the charter school engage legal counsel with charter school experience in order to ensure an equitable and appropriate contract. Legal representatives from both parties will prepare language and deliberate issues on behalf of their respective entities; however, the founding charter school board should be prepared to review several revisions of the contract prior to signing the final version of the contract. The process of negotiating the contract may only take a few weeks, or may require the entire ninety days. The seated charter school board president should sign the contract on behalf of the school.
