Thailand's international schools are concentrated in Bangkok, with strong smaller clusters in Phuket, Pattaya and Chiang Mai. At the upper-tier schools, expect annual tuition of about THB 500,000 in the early years and THB 1.0 to 1.3 million in the final years. On Koh Samui, in Hua Hin and in Krabi the choice is narrow, and for a family with children that can settle the question of where to buy.
Fees below are annual tuition for 2026/2027, from the lowest year group to the highest. Schools revise them each year, so confirm with the school before you rely on them.
Bangkok
Bangkok has 104 international schools. The schools most often shortlisted by relocating families are these.
| School | Curriculum | Annual fees (THB) |
|---|---|---|
| Bangkok Patana School | British, IB | 545,000 to 1,044,000 |
| NIST International School | IB | 650,200 to 1,132,800 |
| International School Bangkok (ISB) | American, IB | 681,000 to 1,219,000 |
| Harrow International School Bangkok | British | 634,600 to 1,063,000 |
| Shrewsbury International School Bangkok | British | 696,300 to 1,256,700 |
| King's College International School Bangkok | British | 636,500 to 1,098,500 |
| Wellington College International School Bangkok | British | 639,250 to 1,283,500 |
| Lycée Français International de Bangkok | French | 297,750 to 434,800 |
Location matters as much as reputation. NIST is in the centre, close to Sukhumvit. Shrewsbury's main campus is on the riverside. Bangkok Patana is in the south-east of the city, and ISB and Harrow are in the northern suburbs, a long drive from the centre at school-run times. Families often choose the school first and then a home on the right side of town. See Bangkok.
Phuket
Phuket has 19 international schools, and that range is one of the main reasons families choose the island.
| School | Curriculum | Annual fees (THB) |
|---|---|---|
| British International School, Phuket (BISP) | British, IB | 489,000 to 982,700 |
| UWC Thailand | IB | 345,000 to 933,000 |
| Glenalmond Phuket International School | British | 490,000 to 750,000 |
| HeadStart International School | British | 347,000 to 540,000 |
| BCIS International School Phuket | British, French | 302,000 to 502,500 |
| Kajonkiet International School Phuket | British | 285,000 to 454,000 |
| Finnway International School Phuket | Finnish | 295,000 to 447,000 |
| Lighthouse International School Phuket | British, Canadian | 240,000 to 368,000 |
BISP is in the centre of the island, north of Phuket Town. UWC Thailand is in the north-east. Both are a manageable drive from the villa areas of Bang Tao and Layan, which is part of why those districts attract family buyers. From Rawai and Nai Harn in the south, the run to either school is long. See Phuket.
Pattaya and the Eastern Seaboard
There are 20 schools around Pattaya, serving both resident families and staff of the nearby industrial estates.
| School | Curriculum | Annual fees (THB) |
|---|---|---|
| Rugby School Thailand | British | 572,000 to 999,000 |
| St. Andrews International School Green Valley | British, IB, Dutch | 443,500 to 867,500 |
| Regents International School Pattaya | British, IB | 440,800 to 854,050 |
| Tara Pattana International School | British | 273,000 to 665,000 |
| International School Eastern Seaboard | American, IB | 357,600 to 646,000 |
Most of these are inland, east of the city, so a car is needed from the beach districts. See Pattaya.
Chiang Mai
Chiang Mai has 20 international schools at fees well below Bangkok's.
| School | Curriculum | Annual fees (THB) |
|---|---|---|
| Prem Tinsulanonda International School | IB | 416,000 to 814,000 |
| Lanna International School Thailand | British | 423,400 to 813,400 |
| Panyaden International School | British, IB | 321,000 to 594,000 |
| Chiang Mai International School | American | 341,700 to 590,200 |
| Nakornpayap International School | American | 304,500 to 521,800 |
Families should weigh the February to April smoke season, when air quality is poor. See Chiang Mai and climate and seasons.
Koh Samui, Hua Hin and Krabi
Choice narrows quickly outside the four main centres.
- Koh Samui has eight schools. International School of Samui has the highest fees, at THB 456,252 to 649,514, followed by PBISS at THB 255,500 to 470,340. See Koh Samui.
- Hua Hin has five. Hua Hin International School, British and IB, charges THB 603,150 to 740,550. The others charge under THB 200,000. See Hua Hin.
- Krabi has one, Krabi International School, following the British curriculum at THB 279,500 to 384,400. See Krabi.
A single-school town carries a risk. If the school does not suit your child, the alternative is boarding or moving.
How to budget and choose
Fees rise through the school, so use the final-year figure when planning. For two children at an upper-tier school, allow THB 1.5 to 2.4 million a year in tuition before extras. Our cost of living guide puts that in the context of a household budget.
Visit before you buy property. Admissions at the most popular schools are selective, some year groups have waiting lists, and the academic year starts in August. Then draw the school-run on a map and look for a home inside it. The area matchmaker can filter by family priorities.
