British (English National Curriculum, IGCSE + IB Diploma) · Rama 9 (main campus) & Langsuan
Regent's runs two central Bangkok campuses — the main Rama 9 campus and a Langsuan campus in Lumphini, Pathum Wan — teaching the English National Curriculum through IGCSE, then the IB Diploma Programme in the sixth form, alongside a Round Square affiliation and one of the few central-Bangkok boarding programmes. In 2025 the school joined the Nord Anglia Education group. Its exact founding year is reported inconsistently across sources (variously cited as 1996 or 2000), so we are not stating one here rather than guess.
Address: Main campus: Rama 9 Road, Wang Thonglang, Bangkok. Langsuan campus: Soi Langsuan, Lumphini, Pathum Wan, Bangkok.
A main Rama 9 campus with a swimming pool, football field, performance studios and dedicated music and visual-arts facilities, plus boarding houses; the Langsuan campus is a small central site.
Getting there: The Rama 9 campus has expressway access and the MRT Blue Line in the district, but is not a walk-up; the Langsuan campus is central and close to BTS Chit Lom and Ratchadamri. Most Rama 9 families drive or use the school bus.
Bangkok school runs are decided by traffic, not distance. Cross-check with the Bangkok getting-around guide and the BTS and MRT network before you commit to a neighbourhood.
How a child progresses through the school, stage by stage:
Accreditation is the closest thing to an objective quality signal in international schooling — it means an outside body has inspected governance, teaching and safeguarding. BAANLYY does not rank schools, so this is what Regent's International School Bangkok and its accrediting bodies publish, not our verdict:
Boarding: Day and boarding at the Rama 9 campus, with boarding reported from Year 4 — a rare central-Bangkok boarding option.
Scale: A mid-sized international community with a Round Square service-and-adventure emphasis that shapes the co-curricular programme. Roll and nationality figures move every year and schools report them differently — treat these as indicative and ask the admissions office for the current numbers.
Families who want an IB sixth form on a British foundation, boarding without moving to Don Mueang or Min Buri, and those drawn to the Round Square ethos.
This is our editorial read for relocation planning, not a ranking or a recommendation — and no school pays to appear on BAANLYY. Visit shortlisted campuses before you decide.
Which campus matters: Rama 9 families sit along the Blue Line and Ladprao, Langsuan families are in the Chit Lom and Lumphini core.
Check the school's bus catchment before you sign — a home that looks close on a map can sit outside the route, and a home on the route can be twenty minutes further away and still be the easier morning.
BAANLYY deliberately does not publish per-school tuition figures: they change annually, schools publish their own current schedules, and a stale number is worse than none. Take this list to the admissions office:
