Which school has the better IBDP — Garden or Regents?

By publicly verifiable outcome data: Garden International Rayong publishes a published 100% Diploma pass rate in 2023. Regents International Pattaya does not publish identical figures publicly — verify the current-year pass rate during your tour. Both are IBO-authorised and well-established IBDP programmes.

What's the structural difference at Sixth Form?

Regents offers BOTH IB Diploma and A-Levels at Sixth Form — students can choose pathway after IGCSE. Garden is IBDP-led at Sixth Form. For families wanting the option to switch from IBDP to A-Levels at G11, Regents is the structural fit; for families committed to IBDP, Garden is the more focused option.

Which is CIS-accredited?

Both are CIS-accredited (Council of International Schools), but Garden International Rayong holds CIS as its primary international accreditation — the only school in the Pattaya/Rayong region with that specific accreditation depth. Regents is part of the Nord Anglia Education group (80+ schools globally), which provides operating consistency beyond CIS.

// 02 · Decision framework

Which IBDP school
for which family.

Choose Garden Rayong if…

IBDP pass-rate consistency matters most. Garden publishes a 100% Diploma pass rate for 2023 (its official examination-results page shows 100% in 2023, 89% in 2022, 100% in 2021). Verify the latest cohort size and average points with admissions.
You value CIS as the most rigorous accreditation. CIS is a 5-year audit cycle covering governance, learning outcomes, child protection, and finance. Garden is the only school in the Pattaya/Rayong region holding it as a primary accreditation.
You value broader language exposure. Garden teaches Spanish + French + Mandarin alongside English and Thai — broader than Regents' three-language offering.
You're in Rayong or Ban Chang already, or comfortable with the 30-min daily commute from central Pattaya.
You want a smaller, more focused IBDP-led pathway rather than the IBDP-or-A-Level optionality model.
You're committed to IBDP — no chance you'd switch your child to A-Levels at G11.

Choose Regents Pattaya if…

You want the IBDP+A-Level optionality at G11. Regents is the only school in the region offering BOTH pathways — students choose after IGCSE. For families uncertain about IBDP vs A-Level at age 16, this is the structural fit.
You value the Nord Anglia global network. 80+ schools across 30+ countries — relocation portability, cross-network teacher exchanges, MIT for STEM and Juilliard for performing arts partnerships.
Boarding from Year 3 matters. Garden is day-only; Regents offers boarding from age 7-8.
You're based in central Pattaya / Banglamung and don't want a 30-min daily commute to Ban Chang.
You want a school with a bigger campus footprint and deeper extracurricular benches than Garden.

Cost comparison summary

Across the secondary years, Regents is approximately ฿200,000-฿250,000/yr more expensive than Garden — a ~30-40% premium at the top end. Over a 6-year secondary schooling, the cumulative cost difference is around ฿1.2-1.5 million. Whether that swings the decision depends on whether the Nord Anglia network, the IBDP+A-Level choice, and the closer-to-Pattaya location justify the premium for your family.

Neither fits if…

You want British curriculum but A-Levels only (no IBDP) — look at Rugby School Thailand at Premium tier or TPIS at Established. Or if you want IBDP at a lower fee point — ISE in Sriracha pairs American curriculum with full IBDP at G11-12 at ฿646K (cheaper than both Garden and Regents).
