The international-school landscape in Thailand has its own academic calendar, its own jungle of acronyms, its own hidden costs, and a tour-and-application timeline that catches new expat families by surprise. This is the primer to read before you tour your first school.
Thai international schools follow the northern-hemisphere academic calendar — most start in mid-August and end in mid-June, with three terms of roughly 12 weeks each. Common term structure: Term 1 (mid-Aug to mid-Dec), Term 2 (early Jan to late March), Term 3 (mid-April to mid-June). This is opposite to the UK academic year (September start), opposite to the Thai national-school year (mid-May start), and aligned with American schools — which is why Pattaya international schools work cleanly for transfers from Singapore, Hong Kong, Dubai, and US international postings.
Year 11 (IGCSE) and Year 13 (A-Level / IBDP) run only two terms rather than three, because the third term is replaced by external exam sessions and the start of university applications. Schools that publish per-term tuition (like Garden International Rayong) charge a 2-term total for exam years; schools that publish per-year tuition (like Rugby and Regents) bake the shorter year into the annual figure. Either way: your Y11 / Y13 child is in school for fewer weeks than the previous year, but the fee per week is higher.
October half-term break (1 week), Christmas break (3–4 weeks), February half-term (1 week), Easter / Songkran break (2–3 weeks aligned with Thai New Year in mid-April), summer break (mid-June to mid-August, ~8 weeks). The 8-week summer holiday is when most relocations happen — if you're moving to Pattaya in July, your child likely starts at the new school in August.
Twenty-plus acronyms get thrown at parents during a school tour. Here's what each actually means and why it might matter for your child.
The UK national framework for ages 2–5. Play-based, structured around "seven areas of learning." All UK-curriculum schools in this directory use it for Nursery + Reception. Some pair it with Montessori or Reggio Emilia approaches.
A theme-based primary framework designed for internationally mobile families — same units of study across IPC schools globally so transfers work cleanly. Used by Regents and other Nord Anglia schools.
The UK government's school curriculum — what's taught in English state schools. The default "British curriculum" at international schools in Thailand. Covers Key Stages 1–4 (ages 5–16).
The international version of UK GCSEs. Taken in Year 11 (age 15–16). 8–10 subject exams. Awarded by Cambridge (CAIE) or Pearson Edexcel. The standard pre-Sixth-Form qualification at all British schools in this directory.
Sixth Form qualification, ages 16–18. Students typically take 3–4 A-Levels, going deep on specific subjects (e.g., Maths, Physics, Chemistry for a Cambridge engineering application). The standard UK university entry route. Offered by Rugby, Regents, and several others.
The International Baccalaureate's Sixth Form qualification. Students take six subjects across six groups (languages, social sciences, sciences, maths, arts, plus a personalised one), plus the Extended Essay, Theory of Knowledge, and CAS (Creativity-Activity-Service). Broader than A-Level. Offered by Regents, Garden, St Andrew's GV.
The IB framework's earlier stages. PYP = Primary Years (ages 3–12), MYP = Middle Years (ages 11–16). Inquiry-based, transdisciplinary. PYP is offered at St Andrew's GV and others.
College-level exams offered by the US College Board. Used by American-curriculum schools as an honours track. In the Pattaya/Eastern Seaboard region, ISE offers select AP courses alongside its IB Diploma. Helps US college applications — UK universities recognise AP but typically prefer A-Levels or IB.
External quality-assurance accreditation cycle covering governance, learning outcomes, child protection, and finance. Re-audited every 5 years. The most rigorous international-school accreditation. In Pattaya–Rayong, only Garden International holds it.
One of the two main exam boards for IGCSE + A-Level (the other is Pearson Edexcel). Cambridge-accredited schools have been audited to teach the Cambridge curriculum to standard.
The body that runs the IB programmes (PYP, MYP, DP). A school must be IBO-authorised to teach the IB curriculum and offer its exams.
UK-based educational charity that runs an inspection-style accreditation for international British schools. Gold is the top tier. St Andrew's GV and Tara Pattana hold EDT accreditations.
The US regional accreditation body. American-curriculum schools serving US-bound students need WASC for credential recognition. In the Pattaya/Eastern Seaboard region, ISE holds WASC (continuously since 2000).
Regional schools-association running inter-school sports, debate, Model UN, and music competitions across Bangkok, Singapore, KL, Phuket, Vietnam, Indonesia. Founding-member status matters for competitive students. Garden is a founding member.
Thai Ministry of Education's external assessment body. Schools operating in Thailand under the Thai MoE need ONESQA accreditation. Most international schools also carry it alongside their international accreditations.
Thai Ministry of Education frameworks for bilingual schools. EP teaches roughly half the curriculum in English; MEP teaches a smaller proportion. BEST and Phoenix Wittaya use EP-style programmes.
For an August intake, the application process realistically runs 9–12 months ahead at the popular premium-tier schools. Several Pattaya schools have waitlists for specific year-groups, so the "we'll just look at this in May" approach can leave a family without a place. Below is the realistic timeline.
Shortlist. Identify 3–4 schools that match your budget, area, curriculum, and child's age. Use this directory's filters. Open each school's full editorial in browser tabs. Run the compare page if you can't decide between two.
Tour. Book a tour at each shortlisted school via their public admissions form. The tour is the moment to see the campus, observe a class in session, and meet the head. Schools want you to tour at least once before they'll accept an application.
Apply. Submit applications to your top 2–3 schools. Each application requires an application fee (non-refundable, ฿5K–฿7.5K per child), the child's previous school reports, and usually a parent statement. Premium-tier schools may set assessment dates 6–9 months ahead — entrance exams, interviews, possibly a "taster day" where the child spends time in a classroom.
Accept and pay. Schools issue offer letters with a deadline to accept (typically 2–4 weeks). Accepting requires paying the acceptance / enrolment fee. This is the non-refundable big one (฿55K–฿200K).
Logistics. Uniform fittings (most schools require their specific supplier), bus zone enrolment, lunch programme sign-up, vaccination records uploaded, first term's tuition invoice arrives. Cars-and-driver families need to verify drop-off times because campuses are 15–30 minutes from central Pattaya.
The directory is the next step. Filter by area, curriculum, or age. Open three school pages side-by-side. Run a compare. Email the editor if a specific question isn't covered.
Every school in the directory gets the same treatment — anonymous visit, real fee table, "Best for:" verdict, honest trade-offs. Maintained, not abandoned.
