Fee Payment Schedule

Fee Payment Guidelines

Returning Student Deposit

  1. Students who intend to re-enroll at ISD for the 2025-2026 school year must pay a Returning Student Deposit of US $750 by April 15, 2025, to hold a place at ISD.
  2. Students for whom the payment is made after the deadline will forfeit all registration priority and thus be considered a new applicant. Since places are determined on a first-come, first-served basis, students for whom payment is not made by April 15, 2025, may be put on a waiting list.

  3. The Returning Student Deposit is considered an advance payment against tuition and will be deducted from the following year’s invoice. The Returning Student Deposit is fully refundable up to May 1, 2025. After May 1, 2025, this fee is non-refundable.

Tuition Refund Guidelines

  1. In case of withdrawal of a student during the school year, a tuition refund is calculated as outlined below. This refund policy only applies when tuition fees are paid in advance for the full academic year:
  • By November 14, 2025: 67% of yearly tuition
  • By January 12, 2026: 50% of yearly tuition
  • By February 13, 2026: 33% of yearly tuition
  • After February 13, 2026: No refund
  1. To be refunded, parents should send a letter to the ISD Business Office requesting a refund. Please include bank information indicating where the refund is to be sent. A refund is only made by EFT or by check. Payments by installment are not entitled to a refund. Registration and capital fees will not be refunded under any circumstance.
