Ruamrudee International School, widely known as RIS, is one of the longest established international schools in Bangkok, founded in 1957. It delivers an American curriculum with Advanced Placement courses and the IB Diploma in the senior years, which gives families two recognised routes to university from one school. It sits alongside the city American option Wells International and the long established International School Bangkok, and this profile sets out how RIS compares.

Curriculum and academics
Ruamrudee follows the American curriculum, leading to a US high school diploma, with Advanced Placement courses for students who want college level work and the IB Diploma as an alternative senior pathway. That combination is unusual and useful, letting families choose AP depth in selected subjects or the broad, six subject structure of the Diploma. English is the language of instruction across the school.
As a large, long running school RIS offers wide subject choice and strong co curricular provision in sport and the arts. To weigh it against the rest of the field, use the American curriculum schools in Bangkok hub and ask the school for its recent AP and IB Diploma outcomes rather than long run averages.

Ruamrudee fees
Ruamrudee sits in the mid to premium band for Bangkok, with tuition rising through the school and highest in the senior years. The figures here are indicative only and should be confirmed with the school, as fees are reviewed annually. Plan beyond tuition for a one off registration fee, a refundable deposit and optional bus and meal costs.
For the wider cost picture see the Bangkok American curriculum hub, or estimate your own total with the fee calculator.
Admissions
The academic year runs from August and the main intake follows it, with rolling entry where places exist. Families provide recent school reports and applicants complete an age appropriate assessment. Entry to the senior years, and to the IB Diploma in particular, is more considered, with the school checking that a student is ready for the chosen pathway.
As an established school with a loyal community, some year groups can carry waiting lists, so applying several months ahead is sensible.
Location and who goes there
The campus is in Min Buri in the east of Bangkok, a more spacious district away from the central business areas. Families who choose RIS often live in the eastern suburbs to keep the commute manageable, and the school runs an extensive bus network that widens the practical catchment. To compare options on the same side of the city see Wells International and start from the Bangkok city hub.
