Additional charges apply for late registration or changes after deadlines. - Supplementary language classes: Core language instruction is included in tuition; occasional additional native‑language lessons offered via national community groups are charged to parents if arranged. - Selected intercultural trips: Costs for inter‑cultural trips that require flights (within Kenya or international) are charged to parents; flight costs are the family's responsibility. - Student materials / books / replacement items: Replacement costs for lost or damaged books are charged at actual replacement cost. (Textbook/book replacement policy is applied where relevant.) - Uniforms and other optional charges: Uniforms or uniform‑shop charges are not listed as an itemised tuition line in the published fee schedule; families should budget separately for uniform purchase and replacement.
Boarding
- Boarding is not offered; the International School of Kenya operates as a day school. No boarding fees apply.
Billing schedule and payment terms
- Billing cadence: Tuition is published as an annual fee and is payable by semester (two equal instalments). Pre‑payments for a full year may attract a 1% discount where published conditions apply (example on the 2025–2026 schedule). - Payment plans: The Business Manager may negotiate payment plans in US Dollars with a surcharge of 0.5% per month, or in Kenya Shillings with a surcharge of 1% per month. A nominal fee is applicable to authorized payment plans. - Penalties and default: A penalty of 2% per month is applied to outstanding balances that are not paid at the beginning of the semester or that miss payment‑plan deadlines; failure to make payment within 30 days of a deadline may result in student withdrawal.
Refund rules
- Tuition and deposits are non‑refundable after payment except in the single circumstance where a family has paid for a full year and withdraws prior to the commencement of the semester; attendance for any portion of a semester precludes a refund of tuition for that semester. Application fees and Capital Levies are non‑refundable.
Payment currency and how to pay
- Accepted currency: Payments are published in US Dollars. Kenyan citizens may pay in Kenya Shillings (evidence of citizenship required). - Payment method summary: The school publishes that families should contact the Business Office for bank details and payment instructions; payments are processed through the Business Office. Payment plans, bank transfer instructions and other arrangements (including applicable surcharges) are managed by the Business Office. Contact: finance@isk.ac.ke or +254 20 209 1308/9.
Other financial assistance and notes on discounts
- Sibling and family concessions: The Capital Levy reduction noted above applies per additional sibling (USD 500 reduction per additional student for the one‑time Capital Levy). Bus fee sibling reductions are also published. - Financial assistance: ISK offers limited tuition assistance bursaries (ranging from USD 500 up to 20% of a family's total tuition costs) for existing families, and may offer Capital Levy payment plans or partial Capital Levy waivers for new families in need; applications for assistance are handled through the Business Manager.
Key points for budgeting
- Expect initial one‑time charges for new students: Application Fee (USD 400) plus the One‑time Capital Levy (USD 11,000) for K–12 entrants, in addition to the annual tuition for the relevant grade. - Ongoing annual costs include tuition (grade dependent), the annual Capital Levy for returning students (USD 1,550), optional transport (USD 2,200 before sibling reduction), prepaid lunch service, and IB exam or trip‑related charges where applicable.
