(a) Continuous operation. Except as provided in this section, a charter holder shall operate the program as described in the open-enrollment charter for the full school term described in the open-enrollment charter during each year that the open-enrollment charter is in effect.(b) Delayed opening. A charter holder may not delay opening the charter school (district) or any charter campus for longer than 21 days without an amendment to its open-enrollment charter, approved by the commissioner of education, stating that the charter school district or campus is dormant and setting forth the date on which operations shall resume and any applicable conditions for resuming operation that may be imposed by the commissioner. The period of dormancy shall last no longer than 12 months and will expire no later than June 30 in the school year in which the dormancy occurs. At the end of a period of dormancy the charter holder may request an additional period of dormancy of no more than 12 months through an amendment to its open-enrollment charter.(c) Abandonment. Delay of opening or suspension of operations in violation of this section and §100.1035 of this title (relating to Charter Amendment) constitutes abandonment of the open-enrollment charter and constitutes a material violation of the charter contract.
