Billing schedule and payment terms

- The academic year is divided into three terms (Term 1, Term 2 and Term 3); invoices are issued on a term basis and per‑term amounts above were calculated by splitting the annual tuition across these three terms.
- Published school fee information indicates that fees are expected to be paid at the start of each term (fees are required in the first week of a new school term as shown in the school's fee documentation).

Boarding fees

- Boarding is not applicable to the Koh Samui campus; the campus operates as a day school and provides on‑site services such as meals and bus transport rather than boarding accommodation.

Other costs and routinely charged extras

- The school provides and/or organizes: school uniforms, daily food (meals), school bus transportation, extracurricular activities and learning support; these items are additional categories of cost though specific unit prices for uniforms, bus routes, meals or clubs are not published in the public fee schedule.
- Typical additional items that families should expect to budget for (where applicable): school uniform purchases, textbooks and workbooks, optional extracurricular or after‑school activity fees, examination fees for external qualifications, school trip charges, and any targeted learning‑support fees. (No detailed per‑item amounts were published for 2025/26.)

Sibling discount

- A sibling discount is offered: 5% reduction for the second child and 10% reduction for the third child enrolled.

Refund information

- Public fee documents reviewed do not include a detailed, line‑by‑line refund policy for 2025/26; historical fee documentation and published notes indicate fees are due at the start of each term but do not specify standard refund calculations or timelines for that academic year.

Fee payment options

- The school's public pages list contact and admissions procedures but do not publish a definitive list of accepted payment methods (for example: specific bank account details, online payment portals, or card acceptance rules are not shown on the publicly posted fee pages reviewed). Families are typically required to follow the invoicing instructions provided by the school finance office.

- The school publishes a three‑term calendar and the annual tuition figures above; however, detailed line‑item prices for uniforms, bus routes, meals, explicit refund terms and the school's accepted payment methods were not published on the public fee pages and fee documents available for 2025/26. The grade‑by‑grade annual tuition and the single‑year enrolment and administrative fees above are taken from the school fee schedule published for 2025/26.
