Registration and Book Fees are non-refundable and must be paid at the time of registration for each child registered. All tuition payments must be made on or before the day of the month you have chosen, i.e., the due date. Payments received after the due date will incur a late fee for each month. If tuition is in arrears and the late fee is not paid with the tuition, Hellenic American Academy may accelerate the balance of tuition.
