The international schools of Bangkok

In and around Bangkok, 47 schools declare an international accreditation. They trace a corridor to the south-east, away from the Sukhumvit towers where housing supply is concentrated. Around them, large apartments remain the exception.

The criterion: accreditation, not the word “international”

The word “international” is not enough. The International Schools Association of Thailand directory keeps only the schools that declare a school accreditation, from the American ACS WASC to the British COBIS and the French AEFE approval. Watch them appear: 31 points on the map.

The name can mislead

On an ordinary map, an international school is recognised by its name. Accreditation draws another map: Bangkok Prep, The Early Learning Centre and La Petite École do not carry the word, yet they are among the 47 schools we keep.

Method and sources

Prices are asking prices, surveyed on 19 October 2026 in our database. For each development we take the median price per square metre of its unsold units; for an area, the median of those medians, shown only from 20 developments upward. A unit is set aside as an outlier below 10,000 ฿/m², above 1,000,000 ฿/m², above 500,000 ฿/m² on less than 30 m² or with no known floor area, above 500 M ฿, or with less than 10 m² per bedroom. The off-plan share counts developments whose status is known. Distances are measured as the crow flies. Euros are converted at €1 = 38.374 ฿ (13 September 2026).

These are listing prices, not sale prices. No figure on this page is a promise of return.
