British (English National Curriculum, IGCSE + A-level) · On Nut / Sukhumvit 77 (T77)
An independent British-curriculum school established in 2003. Its purpose-built Secondary Campus opened in 2017 in the T77 mixed-use development on Sukhumvit Soi 77 near On Nut BTS, with the Primary school relocating to the same district in 2023 from its earlier Sukhumvit 53 site by Thong Lo. Bangkok Prep is a Cambridge examination centre, taking pupils from Nursery through IGCSE to A-levels.
Address: T77 Community, Sukhumvit Soi 77 (On Nut), Suan Luang, Bangkok
A purpose-built secondary campus inside a planned mixed-use community, with an Olympic-sized pool, a full-size football pitch, a black-box theatre and recording and darkroom facilities.
Getting there: One of the better-connected non-central campuses: the T77 development sits close to On Nut BTS on the Sukhumvit Line, making a rail-based school run realistic from anywhere on the line.
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 Bangkok Prep (Bangkok International Preparatory & Secondary School) and its accrediting bodies publish, not our verdict:
Boarding: Day school — no boarding.
Scale: A mid-sized British school with a strong local-expat and Thai-international mix, anchored to the T77 community around it. 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.
Sukhumvit-line families who want a British A-level school without moving east to Bang Na or north to Don Mueang, and anyone who wants the school run on the BTS.
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.
On Nut and the sois around T77 are the obvious catchment, with Phra Khanong and Thonglor within an easy BTS run.
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:
