KIS International School is one of central Bangkok’s two full IB continuum schools, founded in 1998 in the Ratchadaphisek area. It teaches the International Baccalaureate from the Primary Years Programme through the Middle Years Programme to the Diploma, so children can progress through a single coherent framework from the start of school to university entry. It sits alongside the city IB names NIST and International School Bangkok, and this profile sets out how it compares.

Curriculum and academics
KIS delivers all three IB programmes as a single pathway. The Primary Years Programme runs through the early and elementary years with an inquiry led approach, the Middle Years Programme continues into the secondary school, and students finish with the two year IB Diploma. Because the school is a full continuum IB World School, children move through one framework rather than switching systems, which appeals to internationally mobile families.
English is the language of instruction, with a wide range of additional languages reflecting the school’s international community. To weigh KIS against the rest of the field, use the IB schools in Bangkok hub and ask the school for its recent IB Diploma outcomes rather than long run averages.

KIS fees
KIS sits in the mid to premium band for Bangkok, with tuition rising at each stage and highest in the Diploma years. The figures are indicative only and should be confirmed with the school, as fees are reviewed annually. Budget beyond tuition for a one off registration fee, a refundable deposit and optional transport and meals.
For the wider cost picture see the Bangkok IB 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 Diploma is more considered, with the school checking that a student is ready for the demands of the two year programme.
As a popular central school, some year groups can carry waiting lists, so applying a few months ahead is sensible, particularly for families relocating mid year.
Location and who goes there
The campus is in the Ratchadaphisek area of central Bangkok, served by the MRT, which makes it one of the more central international schools in a city where traffic shapes the school run. Families who choose KIS often live in the central districts within reach of the MRT and BTS lines. To compare central IB options see NIST in Sukhumvit and start from the Bangkok city hub.
KIS reviews
We do not yet hold any verified parent reviews for KIS International School. GlobalSchoolGuide is an independent guide and no school pays to be listed, so we publish a rating only once we have collected enough verified first hand accounts to be fair to both the school and to families reading them. We would rather show nothing than show an invented score.
If your family has attended the school we would value your account of admissions, teaching, pastoral care and value for money. Share it through our school reviews hub and we will add verified contributions to this page.
