We love to work with charter schools! If you are the purchaser for a charter school, please use this listing to purchase a one-year subscription for the family in question upfront. Purchasing the charter option will issue 12 non-expiring credits redeemable for any units of choice from our library, either existing or upcoming. Upon purchase, you will receive an email with information about how to get the credits to the correct family's account. This allows the family to benefit from subscription pricing without recurring payments. Please remember that charter schools must purchase one license for each family using the curriculum.
