Garden’s latest published 2025/26 standard tuition is ฿147,000–฿609,800; ISE’s 2026/27 standard tuition is ฿357,600–฿646,000. Both offer IBDP. Garden follows a British route and boards from Year 5; ISE follows an American route, is WASC-accredited and is day-only. The fee years differ, so compare the child’s exact row and extras.

Garden uses its latest published 2025/26 fee page; ISE uses its school-published 2026/27 schedule. Garden standard years bill three terms, while its Y11 and Y12–13 exam-year totals use the two published terms. ISE figures are tuition only. British and American year groups do not map one-to-one.

Fee comparison uses published 2025/26 figures at peer year-groups. Garden is lower at every overlapping secondary band — Year 1 tuition alone saves ~฿96K/yr (฿418,500 vs ฿514,200); Year 6 band saves ~฿153K/yr (฿447,300 vs ฿600,500); Year 10 saves ~฿117K/yr (฿500,100 vs ฿617,000). ISE early years exceed Garden entry: Pre-K ฿357,600 vs Nursery half-day ฿147,000. Garden Y12–13 IBDP is ฿609,800 annually (฿304,900 × 2 terms) — not directly comparable to ISE G11–12 ฿646,000/yr tuition only; model the full journey with admissions. ISE tuition excludes lunch, bus, uniform, and IB exam fees — add those before comparing all-in. First-year all-in benchmarks: Garden Y1 ≈ ฿590,500 (incl. enrolment + deposit); ISE G11 ≈ ฿736,000 (tuition + application + enrolment). ISE sibling discount: 3rd child enrolment waived · 4th+ waived + 10% tuition. Garden sibling discount not published — verify on tour. Add bus to both — typically ฿55K–95K/yr per child on Pattaya–Rayong or Pattaya–Sriracha routes.
This is the structural fork between these two IB Diploma schools. Garden runs British EYFS through IGCSE to IB Diploma — your child sits Cambridge IGCSE before Sixth Form, then IBDP only (no A-Level alternative). ISE runs American AERO + NGSS from primary through IB Diploma — MAP, PSAT, and SAT integration built into the American track, with an American high-school diploma available at G11–12 alongside IBDP. If your family plans UK or Commonwealth university credentials and British exam culture from early years, Garden. If US-university planning, American transcript portability, or NGSS science standards matter, ISE is the only school in this directory with a full American-through-IB pathway.
Garden holds full CIS accreditation — the only school in the Pattaya–Rayong corridor with CIS in our verified record — plus current FOBISIA membership; the federation says it joined in 2002 or earlier. It publishes IBDP examination results (100% Diploma pass rate in 2023). ISE holds WASC accreditation since 1999 and runs a deliberately small campus (a published student-to-teacher ratio below 8:1, with current enrolment not published) inside Burapha Golf Club — intimacy and US-style accreditation over FOBISIA event access. If external academic audit via CIS and competitive regional sport matter most, Garden. If WASC credentials and a small-school culture fit your child better, ISE.
Garden is in Ban Chang, Rayong; ISE is inside Burapha Golf Club in Bowin, Sriracha. Neither is a Pattaya-side school, and a single minute estimate would hide large differences between home addresses, pickup routes and school traffic. Test both journeys at school-run times before enrolling. If you live in Rayong or Ban Chang, Garden is usually the structural fit; if you are based in Sriracha, Laem Chabang or the Bowin industrial corridor, ISE is usually the structural fit.
Both schools publish verifiable year-by-year numbers — this pairing allows a symmetric fee comparison at peer stages, with one caveat on billing structure. Garden: ฿147K (Nursery half-day) → ฿419K (Y1–2) → ฿447K (Y3–6) → ฿500K (Y10) → ฿609.8K (Y12–13). ISE: ฿358K (Pre-K) → ฿514K (K–G5) → ฿601K (G6–8) → ฿617K (G9–10) → ฿646K (G11–12 IBDP tuition only). Garden is lower at every overlapping band. Garden's IBDP fee is ฿609,800 annually, billed as ฿304,900 × 2 terms; ISE G11–12 is ฿646,000/year tuition only. Add ISE lunch, bus, and exam fees before comparing all-in. Budget the full 2–18 journey with admissions on both sides.
Garden offers broader language exposure from primary (Spanish + French + Mandarin alongside Thai) and publishes IBDP pass rates on its official results page — verify latest cohort size and average points on tour. ISE integrates MAP benchmarking, PSAT, SAT, and TOEFL preparation into the American track and offers both IB Diploma and an American high-school diploma at G11–12 — optionality Garden does not provide. If you are committed to IB Diploma only and want CIS audit rigour with FOBISIA competitive circuits, Garden. If you want American diploma fallback alongside IBDP or need WASC-recognised US transcript portability, ISE.
You need Pattaya-side premium IB with boarding — see St Andrew's vs Regents. You want Rayong IB without American overlap — see Garden vs St Andrew's. You want American + IB at lower fees in Nongprue — see ISE vs MIS. You need Nord Anglia IBDP + A-Level optionality — see Garden vs Regents.
Give both admissions teams the same child profile: current year group, reports, home languages, intended entry date, any English-language or learning support, transport address and likely university system. Ask each school to reply with the proposed class, curriculum route, support assessment, standard tuition, mandatory first-year charges, recurring extras, transport quote and payment deadlines. Garden’s latest published tariff is 2025/26 while ISE’s is 2026/27, so a Garden offer should identify the fee year that will actually apply rather than silently carrying the older schedule forward.
For an older pupil, request the exact qualification plan as well as the price. Garden should confirm the IGCSE subjects available to the relevant cohort and the route into its IB Diploma. ISE should confirm the American-diploma and IB Diploma choices, prerequisites, counselling timeline and any examination charges outside tuition. Ask both schools how a pupil joining mid-pathway is assessed and which subjects may be unavailable because of prior study or timetable blocks.
Finally, run both journeys at the actual drop-off time and visit the year group the child would enter. Compare classroom language, teacher feedback, peer interaction and the way support appears during an ordinary lesson. The defensible choice is not “British” or “American” in isolation; it is the school whose daily route, child-specific placement, complete invoice and later qualification plan remain workable together.
Yes. Garden runs British EYFS through IGCSE to IB Diploma. ISE runs American AERO + NGSS through IB Diploma (American diploma also available at G11–12). Garden offers boarding from Year 5; ISE is a day school.
Garden is lower at most overlapping peer stages: Year 1 ฿418,500 vs ISE K–G5 tuition ฿514,200; Year 6 band ฿447,300 vs ISE G6–8 ฿600,500; Year 10 ฿500,100 vs ISE G9–10 ฿617,000. ISE early years (Pre-K ฿357,600) exceed Garden half-day Nursery (฿147,000). Garden Y12–13 IBDP is ฿609,800 annually (฿304,900 × 2 terms) — not directly comparable to ISE G11–12 ฿646,000/yr tuition only.
ISE only. Garden runs British EYFS through IGCSE to IB Diploma — no American AERO/NGSS track. ISE is the only school in this directory with a full American-through-IB Diploma pathway.
Garden holds full CIS accreditation alongside current FOBISIA membership; the federation says it joined in 2002 or earlier. Garden also publishes IBDP examination results. ISE holds WASC accreditation (since 1999) and IBO authorisation — not CIS in our verified record.
If you live in Sriracha, Bowin or Laem Chabang, ISE is usually the structural commute fit inside Burapha Golf Club. Garden in Ban Chang generally suits families south of Pattaya or already in the Rayong corridor. Test both routes from the real home at school-run times before enrolling.
