Early payment (pronto pago) discount: 5% on the net fee when paid by bank transfer/deposit and within the prompt-payment terms specified on the invoice. Discounts are conditional and may be revoked for late or missed payments; discounts do not apply to the reservation of vacancy.
Boarding - Boarding is not applicable; the school operates as a day school at the Belgrano and Tortuguitas campuses (no boarding fee is provided in the school fee communications).
Other costs - Uniforms: no separate uniform charge is itemized in the 2026 fee communications; uniform costs (if any) are treated as an additional family expense outside the published monthly tuition items. Materials and specific activity costs (field trips, camps, competitive trips) may be billed separately when they occur.
Refund information and cancellation - Reservation of vacancy refund: the reservation payment is refundable in full (at historical values) only if parents formally express withdrawal before December 31 of the payment year; if the school cancels the placement, the amount paid will be refunded.
