The commission shall receive applications for initial chartering and renewals of charters for charter schools that want to be chartered by the state and approve or disapprove those charter applications. The commission may approve, deny, suspend or revoke the charter of a state-chartered charter school in accordance with the provisions of the Charter Schools Act. The chartering authority for a charter school existing on July 1, 2007 may be transferred to the commission; provided, however, that if a school chartered under a previous chartering authority chooses to transfer its chartering authority, it shall continue to operate under the provisions of that charter until its renewal date unless it is suspended or revoked by the commission. An application for a charter school filed with a local school board prior to July 1, 2007, but not approved, may be transferred to the commission on July 1, 2007.
