IB fees, DHL costs and Kenya National Examination Council fees are charged to families; parents are billed in October with payment due in November. 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.

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.
Fee details

Annual capital levy is not discounted.
Billing schedule and payment terms
- Academic-year category and due dates (2025/26 schedule example): Fees for Term 1 are due no later than 25 August 2025. A 5% discount on annual tuition is applied when the full year's tuition is paid in advance prior to the start of the school year (example date given: on or before 22 August 2025). Late payments attract a penalty of 2% per month on outstanding amounts. Payment-plan arrangements are available for a plan fee (examples in the schedule: USD 150 per year); payment-plan installments are required to follow the school's prescribed timetable (first installment on or before the first day of school, second one month later, final installment two months after the first day of school). Families are liable for the full term's fees once a term has commenced.
Boarding fees
- Boarding: Woodland Star's published fee schedules and finance policy list day-student tuition, transport, lunch, capital levy and related charges and do not include a separate boarding fee line item. No full-boarding fee schedule is provided in the published fee schedule.
Other costs (uniforms, materials and incidentals)
- Uniforms, stationery and personal school equipment are additional costs payable by families; the fee schedule treats these as separate, variable expenses rather than a fixed recurring school fee. Costs for uniforms and first-term starter packs are charged separately and vary by item and supplier.
Refund information and withdrawal notice requirements
- Notice required to avoid further term charges: Families wishing to withdraw a child must give one full term's notice (i.e., notice on or before the last day of the school term that precedes their child's final term). If notice is given less than a full term but before the next term starts, parents are required to pay 75% of the following term's tuition; where tuition for the following term has already been paid the school will reimburse 25% of that term's tuition. If a student leaves part-way through a term, families remain liable for the full term's tuition. Pre-paid lunches are refundable pro rata if a family leaves part-way through a year; pre-paid transport is not refundable. Specific provisions apply to refunds where learning support services have been engaged. The registration deposit is refundable in line with the published policy when applied as described, but is non-refundable if a place is cancelled after payment and before term commencement in certain circumstances.
Fee payment options and charges
- Bank transfer to school accounts (Kenyan Shilling account details and international transfer instructions are provided in the school's finance information). - Credit card payments are accepted at the finance office; a credit-card processing surcharge applies (example: a 3% surcharge when paying by card). Other local payment methods and the option to arrange approved payment plans are available through the finance office. Payment instructions, required references and bank details are provided by the school's finance office. Late-payment and non-payment consequences (penalties, withholding of reports/transcripts, and potential exclusion from classes until accounts are cleared) are stipulated in the finance policy.

Admissions
Admissions
Step 1 - Create an Account. Begin by creating an account in the ISK application system, then return to the ISK Application Dashboard and select the appropriate year of entry. Step 1 also guides you to prepare for the online application submission. Step 2 - Submit an Online Application. Return to the dashboard to submit the online application for your child and ensure the year of entry is correct. Upload the requested documents: school reports from the previous three years translated into English, the Confidential School Report (sent directly to ISK via the dashboard), a Health Form, most recent MAP scores for Grades 3 and above, a current passport photo, and a copy of the student's passport bio data page. Include proof of payment of the US$400 non-refundable application fee and upload the Commitment to our Educational Philosophy form. Step 3 - Application Review and Next Steps. After submission, you will receive an email confirmation that the admissions team has received the application, and the status can be checked on the dashboard. The principal for each division makes all admission and grade placement decisions, with grade placement generally based on the student's age on September 15 and prior grade equivalence. Next steps include Entrance Assessments and Admissions Decisions, which determine whether ISK can provide the appropriate program for the student. The school also conducts orientation for new families at the start of each school year and for new admissions after mid-year.
Admissions
1. Rolling admissions are offered throughout the year, provided there is space in the appropriate classroom, for students aged two to thirteen. The school accepts applicants year-round in a manner that respects class capacity and diversity of learners. The program welcomes students with special educational needs on a case-by-case basis and considers readiness for entry into the school.
2. Selection is based on five criteria: learners must demonstrate school-readiness; there must be available places in the class (with maximum class sizes defined to maintain quality); the school must be able to meet the learner's support needs; the parent/guardian's ability to pay fees (with or without financial assistance); and whether the learner can cope with the medium of instruction.
3. The application process begins with completing the online application form and submitting it to the school. Primary and middle-year applicants must also provide documents including a completed school character/reference form from the previous school, previous school reports, standard examination/assessment results if available, and any relevant additional documentation such as IEPs or assessments.
4. If further academic assessments are deemed necessary, the school may require testing or evaluations to be completed by an external evaluator, at the parents' expense.
5. A credit reference check may be undertaken, which may include contacting the current school.
6. The application is screened for eligibility by school leadership against the stated criteria.
7. If necessary, the learner and the parent(s)/guardian(s) may be interviewed as part of the admissions process.
8. If the application is successful, the parent(s)/guardian(s) sign a financial agreement and pay a registration deposit of $1,000, which is rolled over and applied to the tuition fees of the last term of the academic year.
9. The parent(s)/guardian(s) sign an agreement to uphold the Village Rules and the school's policies and procedures. The principal informs the parent(s)/guardian(s) of the admission status, and reasons for non-admission can be provided on request.
