2 · British (IGCSE / A Level)

The default in Thailand — the largest group in our dataset, from Bangkok Patana and Shrewsbury down to small primaries. Strengths: a transparent exam ladder, deep subject teaching, and A Levels that every university system on earth can read. Watch-outs: specialisation comes early (a student weak in a dropped subject can't recover it), and "British curriculum" spans everything from rigorously inspected schools to marketing labels — check for Cambridge/Edexcel exam-centre status and BSO or equivalent inspection. Browse British schools in Bangkok.

3 · IB (PYP / MYP / DP / CP)

The IB is a programme framework, not a nationality: schools must be authorised by the IB Organisation for each programme they offer (verify any school on ibo.org — see our accreditation guide). Thailand's IB schools range from full PYP–DP through-schools to DP-only sixth forms. Strengths: breadth, research and writing skills, and a diploma universities worldwide understand. Watch-outs: the DP is a heavy two-year load, and MYP-only or candidate schools are sometimes marketed as if fully authorised. Browse IB schools in Bangkok.

4 · American (US diploma / AP)

Built around a credit-accumulating diploma and GPA, with Advanced Placement courses as the honours track. Strengths: flexibility, continuous assessment instead of one exam season, and a natural fit for US admissions. Watch-outs: diplomas are only as credible as the school's accreditation (look for WASC or Cognia — membership of a US-flavoured association is not the same), and AP breadth varies hugely between schools. Browse American schools in Bangkok.

5 · The other systems

Canadian (including Ontario OSSD pathways), Australian, Singapore, French (AEFE network), German-Swiss, Japanese, Korean, Chinese and Indian-curriculum schools all operate in Thailand, mostly in Bangkok. They serve their national communities first but are rarely closed to others; the practical filter is the language of instruction. All appear, labelled, in the directory.

6 · How families actually choose

Three questions decide it for most families: (1) Where might your child study next? — match the diploma to the likely destination system. (2) How does your child respond to exams vs continuous assessment? — A Level/IGCSE concentrates risk in exam seasons; the American model spreads it; the DP spreads it but never lets up. (3) How long will you stay? — short postings favour the system of the next country, not this one. Then use the finder quiz and compare tool on the schools that fit.
