Choosing an international school in Phuket involves a variable most expat destinations do not have: a large share of the families around you are here by choice rather than by posting. That changes the market. Corporate hubs like Singapore or Bangkok have schools built around three-year assignments. Phuket has schools built around families who moved for the island and intend to stay, alongside boarding operations serving the region. Understanding which type of school you are looking at is the first real decision. This 2026 guide covers what is available, what it costs and where the traps are.
Understand the island before the school
Phuket is roughly fifty kilometres long, and the road network was not designed for the traffic it now carries. School location is therefore not a detail, it is a daily constraint. The island breaks into three practical zones:
- The west coast, from Bang Tao and Cherng Talay down through Kamala and Patong. Where most international families live and where the largest school campuses sit. High-season traffic on the main coastal roads is genuinely bad.
- Phuket Town and Chalong, in the south east. More Thai, better value housing, easier daily logistics and closer to several mid-market schools.
- The north, toward Thalang and the airport. Quieter, cheaper, longer commutes to almost everything.
A commute that looks like twenty minutes on a map can be fifty in February. Drive the actual route at the actual school-run hour before you sign a lease. Families who choose the house first and the school second regret it more often than the reverse.
Curricula available in Phuket
Three routes dominate. Cambridge International, the British model, is the most widely available and takes children to IGCSE at 16 and often A Levels after. The International Baccalaureate Diploma is offered by the larger campuses and suits students who want breadth and a research component. Montessori and play-based early years provision is unusually strong on the island, reflecting the number of families with young children.
If there is a realistic chance you will move again, weight curriculum portability heavily. A child part way through IGCSE who transfers into a different system loses ground that is hard to recover. If you are certain you are staying through to university, the choice opens up considerably.
Schools worth shortlisting
British International School Phuket
The largest and best-known campus on the island, in the Cherng Talay area, running the British curriculum through IGCSE and then the IB Diploma, with day and boarding places. It is also notable for structured sports academies in disciplines including tennis, football and swimming, which attracts students from across the region. If your child is serious about a sport, this changes the calculation. Full profile: British International School Phuket.
HeadStart International School
A Cambridge school with a substantial local and international intake, positioned toward the south of the island. Generally more affordable than the west coast campuses and popular with families living in and around Phuket Town and Chalong. See HeadStart International School.
BCIS Phuket
A Cambridge-track school offering a smaller, more contained environment. Small cohorts mean genuine teacher attention but a narrower range of IGCSE options, so check the subject blocks carefully against your child's intended pathway. Profile: BCIS Phuket.
International School of Phuket
Another established Cambridge option on the island, with fees generally in the mid-market band. Ask for the IGCSE results history and destinations of recent leavers, which tells you far more than a facilities tour. See International School of Phuket.
Montessori House Phuket International School
For families with children in the early years, a dedicated Montessori setting rather than a Montessori-flavoured nursery attached to a larger school. Worth considering if the pedagogy matters to you, with the obvious caveat that you will need a transition plan for primary. Profile: Montessori House Phuket International School.
What it costs in 2026
Phuket spans a wide range. As a broad annual guide:
- Early years and primary: roughly THB 200,000 to THB 500,000
- Lower secondary: roughly THB 400,000 to THB 750,000
- IGCSE and IB Diploma years: roughly THB 550,000 to THB 1,100,000
- Boarding, where offered: add roughly THB 400,000 to THB 800,000
Add registration and application fees, a refundable deposit of around one term, uniforms, books, devices, transport and examination entry fees. Realistically these push the all-in figure 15 to 25 percent above headline tuition. Sports academy programmes are usually charged separately and can be substantial. Ask for a written full-year cost schedule from every school on your list, and confirm whether figures are per term or per year before comparing.
The two questions specific to Phuket
Ask about teacher retention. This is the most important question on the island and the one most parents forget. Lifestyle destinations attract teachers who come for a year and leave. A school with high churn cannot build consistent teaching, and your child pays for it. Ask directly what percentage of teaching staff returned this academic year, and how long the head of your child's section has been in post. A confident school gives you a number.
Ask about cohort size in your child's actual year group. School-wide figures hide a lot. A school of 600 can still have eleven children in Year 9, which limits friendship groups, subject options and team sports. Get the number for the specific year your child is entering, not the average.
Practical admissions notes
The academic year runs from mid-August to June across most of the island, with a January entry point at several schools. Rolling admissions are the norm, so apply as soon as your move is confirmed. Expect an English and mathematics assessment plus an interview, and ask precisely how much EAL support is provided if English is an additional language. Documents to prepare in advance include passports, birth certificate with certified translation if needed, two years of school reports in English, a transfer certificate and immunisation records.

Frequently asked questions
How much does an international school in Phuket cost per year?
Expect roughly THB 200,000 to THB 500,000 a year in primary, THB 400,000 to THB 750,000 in lower secondary and THB 550,000 to THB 1,100,000 in the IGCSE or IB Diploma years, with boarding adding THB 400,000 to THB 800,000 and extras adding 15 to 25 percent.
Which curriculum should I choose for an international school in Phuket?
Cambridge International is the most widely available and highly portable, making it the safer choice if you may relocate again. The IB Diploma is offered by the larger campuses and suits students wanting breadth and research skills. If you are certain you will stay through to university, either works well.
What should I ask a Phuket school before enrolling?
Two questions matter most on the island: what percentage of teaching staff returned this academic year, which reveals turnover in a lifestyle destination, and how many children are in your child's specific year group rather than the school as a whole.
