Garden’s 2026/27 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. Compare the child’s exact row, inclusions and extras.

Garden and ISE both use their school-published 2026/27 schedules. 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 2026/27 figures at peer year-groups. Garden is lower at the cited overlapping bands: Year 1 tuition is ฿418,500 versus ISE's ฿514,200; the Year 6 band is ฿447,300 versus ฿600,500; and Year 10 is ฿500,100 versus ฿617,000. ISE early years exceed Garden entry: Pre-K is ฿357,600 versus Nursery half-day at ฿147,000. Garden Y12–13 IBDP is ฿609,800 annually (฿304,900 × 2 terms) — not directly comparable to ISE G11–12 at ฿646,000/yr tuition only; model the full journey with admissions. ISE tuition excludes lunch, bus, uniform, and IB exam fees. First-year examples are Garden Y1 at about ฿590,500 (tuition, enrolment and deposit) and ISE G11 at about ฿736,000 (tuition, application and enrolment), before child-specific extras. ISE publishes a third-child enrolment waiver and, for a fourth child or later, the waiver plus 10% tuition discount. Garden does not publish a sibling discount. Request route-specific bus quotes from both schools.
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, with an American high-school diploma and an IB Diploma route at G11–12. The current sources cited on this page do not establish a scheduled MAP, PSAT or SAT programme, a university-application platform service or transfer-credit arrangements. Families planning for a particular university should ask each school to map the intended course against current entry requirements and provide its counselling and testing offer in writing.
Garden holds full CIS accreditation in the current directory evidence, 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 publishes a student-to-teacher ratio below 8:1, while current enrolment is not published. Ask both schools for the proposed class and activity participation rather than inferring daily experience from accreditation, membership or a ratio.
Garden is in Ban Chang, Rayong; ISE is inside Burapha Golf Club at 282 Moo 5, Bowin, Sriracha. Neither address supports a universal commute estimate: travel varies with the family’s exact home, pickup route and school traffic. Test both journeys at school-run times and obtain address-specific bus timings before enrolling.
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 publishes American AERO + NGSS, WASC accreditation and American high-school diploma and IB Diploma routes at G11–12. The current cited source set does not establish a scheduled MAP, PSAT, SAT or TOEFL programme; families needing a particular test, application service or credit-transfer arrangement should request dates, eligibility, fees and staff support in writing.

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. Both schools publish 2026/27 figures, but the quote should still identify the fee year, grade placement and inclusions that apply to the child.
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 is the American-curriculum option in this pairing. Garden runs British EYFS through IGCSE to IB Diploma — no American AERO/NGSS track. Current directory evidence records ISE’s American AERO/NGSS route with an IB Diploma option; confirm the exact senior offer for the intended cohort.
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.
ISE is inside Burapha Golf Club at 282 Moo 5, Bowin, Sriracha; Garden is in Ban Chang, Rayong. Which route works better depends on the real home address, traffic and bus stops, so test both at school-run times before enrolling.
