Full IB (PYP / MYP / DP) · Huai Khwang / Rama 9
A family-owned, full-IB World School operating since 1998, KIS runs the complete IB continuum from Early Years through the Diploma Programme. Its Huai Khwang campus, close to Bangkok's newer Rama 9 CBD, suits families wanting a smaller, close-knit community; KIS opened a second campus, Reignwood Park, in Lam Luk Ka in 2024.
Address: Bangkok campus: 999/123 Pracha Uthit Road, Samsen Nok, Huai Khwang, Bangkok. Reignwood Park campus: 888/99 Lam Sai, Lam Luk Ka, Pathum Thani.
A mid-sized city campus in Huai Khwang, plus a separate, much larger day-and-boarding campus at Reignwood Park in Lam Luk Ka that opened to students in August 2024.
Getting there: The Bangkok campus is off Pracha Uthit Road in Huai Khwang — MRT Blue Line stations at Huai Khwang and Thailand Cultural Centre are the nearest rail, but not walkable from the gate for a young child; most families drive or use the bus. The Reignwood Park campus in Pathum Thani has no rail link at all.
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 KIS International School and its accrediting bodies publish, not our verdict:
Boarding: The Bangkok campus is a day school. Boarding is associated with the newer Reignwood Park campus — confirm current provision directly.
Scale: Deliberately smaller than the big British campuses; families choose KIS partly for the close-knit scale. 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 the full IB continuum in a smaller community, and those based around Ratchada, Rama 9 and the MRT Blue Line rather than Sukhumvit.
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.
The Blue Line corridor through Huai Khwang and Ratchada is the natural catchment, with Rama 9 the upgrade option.
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:
BAANLYY does not rank, endorse or accept payment from schools. Facts on this page are compiled from KIS International School's own official website and its accrediting bodies, and are provided for relocation planning — not as admissions or financial advice. Curricula, campuses, fees and admissions rules change; always confirm current details with the school.
