Billing schedule and payment terms - Tuition may be paid quarterly or annually. Tuition is invoiced as follows: - For new students: the 1st quarter (or the quarter in which the student enters) is invoiced at the time of initial registration; subsequent quarters are invoiced approximately one month before the due date. - For returning students: re‑registration and initial payment deadlines are set in the re‑registration schedule (example dates in the schedule show re‑registration forms and a June payment deadline for the 1st quarter/annual option). Subsequent quarter due dates are published on the annual schedule. - Specific quarter due dates shown in the published schedule include (examples for the year shown): 2nd Quarter due November 6; 3rd Quarter due January 29; 4th Quarter due April 23. Failure to pay the 1st quarter by the deadline cancels the reserved place and invoiced amounts remain due. Individual payment plans may be arranged with the Accounts Manager. - Discounts: 3% reduction on tuition paid in full by the published early‑payment deadline (example: on or before June 15 in the schedule) and 3% reduction on the building fee if paid with the annual tuition by that date. Sibling discounts apply: 15% reduction on Tuition & Building Fee for a third concurrently enrolled child, and 25% reduction for a fourth and subsequent concurrently enrolled child (applied to the youngest children). Early payment discounts are not refundable.
Refunds, cancellations, early withdrawal and related policies - The First Quarter fees (Tuition and Building Fee, if applicable) of attendance are owed as a condition of registering or re‑registering and are not refundable under any circumstances. Failure to pay the 1st quarter by the due date results in loss of the child's place while the invoiced amounts remain due. - Late admission (entry during a quarter): the fee to reserve the place is the full quarter's tuition plus the Registration Fee and the full year's Building Fee if applicable. - Early withdrawal: written notification of intent to withdraw must be given by the published deadlines approximately one month before the next quarter's payment date; failure to provide required written notice results in the full next quarter's fees being due. Any attendance during a quarter results in that full quarter's fees being due. Example deadlines from the schedule are Oct 2 (for 2nd quarter), Dec 18 (for 3rd quarter), and Mar 25 (for 4th quarter). - Refunds for early payments (including discounted annual payments) are not provided; early‑payment discounts will not be refunded under any circumstances.
