Every school comes from our international schools directory, which lists schools licensed by OPEC as international schools or accredited by an OPEC-recognised body.

How primary works in each curriculum

Primary-only schools

These stop at the end of primary, which often means smaller classes and a younger campus, but you will be choosing a secondary school at 11 or 12.

The commute shapes primary years more than anything, so start with the schools near home. Where we know a school’s age range it is shown on the card.

Questions parents ask

What age does primary school start at international schools in Bangkok?

It depends on the curriculum. British schools start Year 1 at five, American schools start Grade 1 at six after a Kindergarten year, and Singapore schools start Primary 1 at six or seven. Year groups are set by birthday, so check each school's cut-off date.

How much does an international primary school cost in Bangkok?

Comparing the year children turn six to seven, the 31 schools that publish that fee range from 175,140 baht a year at Global Indian International School to 1,015,000 baht at International School Bangkok (ISB). Most schools also charge registration and other one-time fees, listed on each school's page.

Which international schools in Bangkok are primary only?

Beaconhouse Yamsaard International School, BSB British International Primary School, Sequoia Nova International Primary School, Siam International School, Singapore International School Suvarnabhumi, St. Andrews International School Dusit, St. Andrews International School Sathorn, Thai International School and The British School of Bangkok (Topsy Turvy) stop at the end of primary, so you will need to choose a secondary school at 11 or 12.

Should I choose a British, American or IB primary school?

At primary age the day-to-day differences are smaller than the labels suggest. The bigger questions are where you may move next, which secondary qualifications you want later, and the commute. If you might return to the UK, a British school keeps year groups aligned; if you expect to move often, an IB school makes transfers between countries easier.

When should I apply?

Many schools admit through the year when there is space, but popular year groups fill for an August start, so contact schools six to twelve months ahead and ask about waiting lists when you visit.
