- Tuition is charged on an annual basis. Tuition may be paid in 10 equal installments or as a one-time payment with a 5% discount when paid in full at enrollment (paid-in-full discount applies only upon initial enrollment/re-enrollment and where the school's paid-in-full conditions are met). For mid-year start dates, at least 50% of the school-year tuition must remain to use the paid-in-full discount. Failure to confirm enrollment by the school's stated deadline will disqualify a family from the paid-in-full and sibling discounts.
