Each professional licensing board is authorized to charge an examination fee, license fee, license renewal fee, or similar fee and may establish the amount of the fee to be charged. Each fee so established shall be reasonable and shall be determined in such a manner that the total amount of fees charged by the professional licensing board shall approximate the total of the direct and indirect costs to the state of the operations of the board. Fees may be refunded for good cause, as determined by the division director.
