Garden vs ISE.
Two schools both offering IB Diploma at Sixth Form with opposite curriculum DNA: Garden in Ban Chang, Rayong — British EYFS through IB Diploma, CIS + FOBISIA founding member (฿147K–500K published · gardenrayong.com) versus ISE in Bowin/Sriracha — American AERO + NGSS through IB Diploma, WASC since 2000 (~150 students · ฿358K–646K · ise.ac.th).

Side by side.
Garden fees from gardenrayong.com/admissions/fees (2025/26). ISE tuition from ise.ac.th 2025/26 schedule, cross-checked with ISD record. Garden invoices per term — standard years multiply by three; Y11 IGCSE and Y12–13 IBDP are 2-term exam-year totals. ISE figures are tuition only — lunch, bus, uniform, and IB exam fees are separate. Grade bands aligned by school stage; 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 uses 2-term billing (฿304,900 total) — 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.
// 02 · The decision framework
Five questions.
Five answers.
1. Do you want IB Diploma on British IGCSE — or on American AERO/NGSS?
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.
2. CIS + FOBISIA circuits — or WASC + deliberately small cohort?
Garden holds full CIS accreditation — the only school in the Pattaya–Rayong corridor with CIS in our verified record — plus FOBISIA founding-member status for regional sports, debate, and Model UN circuits. It publishes IBDP examination results (100% Diploma pass rate in 2023). ISE holds WASC accreditation since 2000 and runs a deliberately small campus (~150 students, 8:1 ratio, 50+ nationalities) inside Burapha Golf Club — intimacy and US-style accreditation over FOBISIA travel circuits. 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.
3. Rayong commute or Sriracha commute — where does your family live?
Garden at Ban Chang, Rayong sits ~30 minutes south of central Pattaya — a daily run many families accept for lower published fees and FOBISIA sports, but not walkable from Jomtien or Naklua. ISE at Bowin, Sriracha sits ~35 minutes east of central Pattaya — structurally closer for families in Sriracha, Laem Chabang, or Bowin industrial corridor. Neither is a Pattaya-side school. Test both commutes at school-run times before enrolling. If you live in Rayong or Ban Chang already, Garden wins logistics; if you anchor east of Pattaya, ISE wins.
4. Can you budget Garden exact fees vs ISE tuition-only structure?
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). 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 secondary band. ISE is higher at entry but offers a lower Sixth Form annual headline only if you ignore Garden's 2-term IBDP billing (฿304,900 total at Y12–13). Add ISE lunch, bus, and exam fees before comparing all-in. Budget the full 2–18 journey with admissions on both sides.
5. British language breadth + published IBDP results — or American diploma optionality at G11?
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.
Summary verdict
- Choose Garden International if: British IGCSE foundation through IB Diploma fits your credentials plan; CIS accreditation and FOBISIA founding-member circuits matter; published fee savings (~฿96K–153K/yr at overlapping bands) matter; you accept a Rayong daily commute or live in Ban Chang; and you are committed to IBDP-only at Sixth Form with published examination results.
- Choose ISE if: American AERO/NGSS through IB Diploma fits your plan; WASC accreditation and a deliberately small cohort (~150 students) matter; you live east of Pattaya (Sriracha, Bowin, Laem Chabang); MAP, PSAT, SAT integration fits US-university planning; and American diploma optionality at G11–12 is valuable insurance alongside IBDP.

// FAQ
Quick answers
before you decide.
Do both Garden and ISE offer IB Diploma?
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). Neither offers boarding.
Which is cheaper — Garden or ISE?
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 uses 2-term billing (฿304,900 total) — not directly comparable to ISE G11–12 ฿646,000/yr tuition only.
Which offers an American curriculum?
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.
Which has CIS accreditation?
Garden holds full CIS accreditation alongside FOBISIA founding-member status and publishes IBDP examination results. ISE holds WASC accreditation (since 2000) and IBO authorisation — not CIS in our verified record.
Garden or ISE for a Sriracha family?
If you live in Sriracha, Bowin, or Laem Chabang, ISE is the structural commute fit — inside Burapha Golf Club, ~35 minutes from central Pattaya. Garden at Ban Chang, Rayong suits families south of Pattaya or already in the Rayong corridor (~30 minutes). Test both school-run commutes before enrolling.
