About international schools in Koh Samui, Thailand

Koh Samui is an island market with a compact set of English-medium international schools rather than the large choice you find in Bangkok or Phuket; most schools on the island follow a British/Cambridge pathway while a smaller number offer bilingual Thai - English streams and at least one French-language option. English is the primary language of instruction across the international schools, with Thai taught as a mandatory or optional additional language and other modern languages offered at some campuses. Annual tuition varies widely by age and provider but typically runs from lower-kindergarten levels through to higher secondary fees that can reach the mid six-hundreds of thousands of baht; on average island fees are noticeably below comparable Bangkok or Phuket schools. Schools on Samui generally publish a British-style, three-term academic calendar (with the main intake ahead of the new academic year) and will set non-refundable joining or capital levies and termly fee payment schedules - so families should check each school’s current fee schedule, published term dates and transport routes before committing.

FAQs for Thailand

Which curricula do Koh Samui international schools typically follow, and will my child be able to transfer back to a school on the mainland or overseas?

Most international schools on Koh Samui follow the British/Cambridge system (including IGCSEs and A-levels) and some operate bilingual Thai - English programmes; there are fewer full IB or American-curriculum options on the island, so families needing those systems should confirm current availability. Schools using Cambridge or the British national framework generally provide structured year groups and recognised external examinations, which makes transfer to mainland or overseas schools straightforward if you match year groups and exam pathways in advance.

How much should I budget for tuition and extra costs?

Tuition on Koh Samui varies by school and year group; parents can expect lower-level kindergarten fees at the lower end and senior school fees that in some cases reach several hundred thousand baht per year, with published examples across the island reflecting a wide range. In addition to tuition, most schools charge a one-off, non-refundable joining fee or capital levy, plus costs for uniforms, exams, extracurricular activities, school meals and optional language support, so request the full, current fee schedule from each school.

When should we apply and how do admissions typically work?

Schools on Samui publish annual calendars and normally run a main intake that aligns with the start of their academic year (British-style term structure), but many schools will accept applications year-round subject to place availability. Because island schools are smaller and places - especially in popular year groups - can fill quickly, start the admissions process as early as possible, bring recent school reports and vaccination/ID documents, and confirm any waiting-list or sibling policies directly with the school.

What language support and Thai language provision can we expect?

Instruction is predominantly in English across Koh Samui’s international schools, and most schools include Thai language and culture lessons either as a compulsory subject or as part of a bilingual stream; several schools also offer additional modern languages such as French, Mandarin or Spanish. If your child needs English-as-an-additional-language (EAL) support, ask for details on the school’s EAL provision, class sizes and how they assess progress - these vary between schools and affect day-to-day learning.

What should we look for during a school visit on Koh Samui?

Ask to see recent inspection or accreditation evidence, sample curriculum maps and external examination outcomes, observe class sizes and a live lesson if possible, and check transport routes and pickup times because commute logistics on the island often influence where families choose to live. Also confirm safeguarding and medical arrangements, how the school supports new international students to settle, and the details of any non-refundable fees or contractual notice periods before you accept an offer.
