Raffles American School Bangkok

An American curriculum K-12 school in Bang Na, Raffles American School Bangkok teaches Common Core standards in language arts and mathematics, Next Generation Science Standards, and uses the IB Diploma Programme as the main academic pathway in Grades 11 and 12. The school holds WASC accreditation, first awarded in 2021 with a mid-cycle review completed in 2024, and is authorised by the College Board to deliver Advanced Placement courses, though AP now plays a supplementary role to the IB DP.

Inquiry- and project-based pedagogy guides classroom work across separate Early Years/Elementary and Middle/High School divisions on a single Bang Na campus. The school sits within the Raffles Education network of campuses across nine countries.

RAS suits families seeking a US-style pathway with an IB exit option, in a smaller school south-east of central Bangkok. Days run from roughly 8:30 to 14:30, with a Sodexo-catered lunch programme and a campus housing science labs, visual and performing arts studios, a performing arts centre, gymnasiums, an athletics stadium, and a swimming pool.

The Raptors Sport Academy competes in BISAL, the Bangkok International Schools Athletic League, with regular fixtures against peer schools across volleyball, basketball, football, and swimming. Two concrete strengths stand out: small class sizes that allow individualised attention from teachers credentialled in the US, Canada, UK, or the British Commonwealth; and explicit language exposure, with Thai and Mandarin taught alongside the English language of instruction.

The Bang Na location places the campus just outside Bangkok in Samut Prakan, on the Bangna-Trat corridor, accessible by car or via the MRT Yellow Line and feeder buses. The trade-offs are real. RAS publishes very limited fee detail, with tuition and a lunch charge listed but no public schedule for registration, bus, books, or deposit fees, so families must request a full quote from admissions.

Student numbers, nationality mix, class size caps, and exam result averages are not disclosed publicly, which makes direct comparison with larger Bangkok schools harder. The IB DP cohort is small and recent, so a long published track record of university outcomes is not yet available. Best for families wanting a US-accredited K-12 pathway with an IB Diploma finish, willing to trade the scale and disclosure of larger competitors for smaller classes, a Raffles-network identity, and a Bang Na location.
