An institution shall be considered in default of the enrollment agreement when an educational program is discontinued or canceled or the institution closes prior to completion of the educational program. When an institution is in default, student institutional charges may be refunded on a pro rata basis if the bureau determines that the school has made provision for students enrolled at the time of default to complete a comparable educational program at another institution at no additional charge to the students beyond the amount of the total charges in the original enrollment agreement. If the institution does not make that provision, a total refund of all institutional charges shall be made to students.
