Billing schedule and payment terms - The school's published information directs parents to request detailed, campus-specific pricing and payment schedules via the information request form rather than publishing a standard public billing schedule; no single, public Istanbul billing calendar (per-term dates or standard installment plan) is posted. - The public pages reference typical discount types such as early (peşin) payment discounts, sibling discounts and academic-bursary discounts, indicating these discount types are used when applicable. Boarding (residential) fees - No boarding or student residence (yurt) option or boarding fees are listed for the Istanbul campuses in the publicly available campus materials; campus pages and the pricing overview focus on day-school services (tuition, meals, transport/service). Other costs and typical additional fees - Meals / cafeteria: published examples and guidance show a separate meal charge; reported meal costs vary (Ankara campus: 104.860 TL per year in the published table; published guidance for kindergartens cites monthly meal ranges of 500 TL–1,500 TL as a general reference). - Books and stationery: shown as a separate annual charge in campus-specific tables (Ankara example: 65.000 TL by grade). - Uniforms: listed as a separate charge in campus-specific tables (Ankara example: 20.000 TL); the school describes uniforms as a standard required item. - Transport / school bus service (servis): described as a chargeable service in campus information; specific Istanbul campus bus fees are not published publicly and are provided on request. - Extracurricular activities, special programmes, external exam fees (Cambridge/IB), school trips and some workshops may generate additional, separate charges; such items are referenced as chargeable extras but detailed fee lines are campus- and activity-specific. Refunds and cancellation - A public, campus-specific refund or fee-cancellation schedule for Istanbul campuses is not posted in the public fee materials; no explicit, detailed refund table or standard refund percentages/dates was located in the published campus fee materials. Fee payment options (methods) - The publicly available information does not list standard, campus-wide payment methods (credit card, bank transfer, etc.) on a single public page; parents are directed to request the campus fee schedule and associated payment terms via the information request process. Practical summary (what these items mean for a parent) - For Istanbul campuses the site publishes tuition ranges by level (kindergarten, primary, middle, high) and describes standard additional charges (meals, books, uniform, transport, extracurriculars). - The school's pricing page instructs parents to request campus- and grade-specific fee schedules and payment terms using the school's information request form; a published, campus-specific Istanbul per-grade, per-term fee table for 2026/27 was not publicly available at the time of review. If you need campus-specific numbers - Campus contact details and campus emails/phone numbers are published for each Istanbul campus (Ataşehir, Bahçelievler, Bahçeşehir, Beylikdüzü). Use the campus contact channel to obtain the precise, campus- and grade-level fee table and the school's official billing schedule and accepted payment methods.	Fee details —
