Best International Schools in Phuket: 2026 Guide for Families

Quick answer: what are the best international schools in Phuket? Five schools stand out for relocating families: British International School Phuket and UWC Thailand for the IB, HeadStart and Kajonkiet for the British and Cambridge route, and QSI for an American-style mastery model. Annual tuition runs roughly 250,000 to 1,000,000 THB (about US$7,000 to $30,000) depending on age and school.

Phuket has turned from a holiday island with a handful of schools into one of the most settled international education markets in Southeast Asia. Families searching for the best international schools in Phuket now have a genuine choice between British, IB and American programmes, several of them on large green campuses that would be hard to find in Bangkok at the same price.

The catch is that "best" means something different for every family. A child heading for UK universities needs a different school from a teenager who will move on to a third country in two years, and a family in Rawai faces a different commute from one in Thalang. This guide explains what to weigh, then walks through five schools and who each one suits.

Phuket for school-age families: areas, distances and the daily drive

Most international families on the island fall into three groups: long-term expats running businesses in tourism and property, professionals working remotely, and families on corporate or hospitality postings. The arrival of the Destination Thailand Visa (DTV) in July 2024, a five-year multiple-entry visa aimed at remote workers, added a fresh wave of relocations, which makes mid-year arrivals more common.

The island is roughly 50 kilometres from north to south, and that matters more than it sounds. The main artery, Thepkrasattri Road, links the airport and Thalang in the north with Phuket Town and Koh Kaew in the centre, and it carries heavy traffic at school run times. The schools cluster in three zones:

Central (Koh Kaew, Vichit, Phuket Town): the most convenient base if you want to reach most of the island in 20 to 30 minutes. BISP and HeadStart sit here.
Kathu: between Phuket Town and Patong, with easy access to the west coast. Kajonkiet and QSI are both in Kathu.
The north (Thalang): quieter, close to the airport and the Laguna and Bang Tao areas. UWC Thailand is here, at the foot of a national park.

Families living in the south, around Rawai, Chalong or Kata, should budget 40 minutes or more each way to reach the northern campuses in peak traffic. Many schools run bus routes, and it is worth asking for the actual timetable from your street before committing to a rental contract.

Which curricula you can find on the island

British and Cambridge (EYFS, IGCSE, A level, BTEC): the largest group. HeadStart follows the English National Curriculum through to A levels or BTEC in the sixth form, and Kajonkiet is widely described by its families as a British curriculum school.
International Baccalaureate: UWC Thailand is an IB school throughout, and British International School Phuket also lists the IB among its programmes, typically for the final two years.
American-style mastery learning: QSI runs the Quality Schools International model, where students move on once they have mastered each unit rather than strictly by age.
Thai national and bilingual programmes: available at Thai private schools, but outside the scope of this shortlist, which focuses on English-medium schools with an international intake.

Five schools worth a visit, and who each one suits

British International School Phuket

BISP sits on Thepkrasattri Road in Koh Kaew, close to the centre of the island, and takes children from nursery all the way to the end of secondary. English is the language of instruction, and students who arrive with limited English can join an Intensive English Programme that runs inside the school day rather than as an add-on. The school states that it actively balances nationalities in each year group, so admissions look at more than academic reports. It holds a 4.8 rating from 4 reviews on its profile, and one parent review highlights a very large campus with specialist academies for football, tennis, golf and swimming.

Who it fits: sporty children and families who want the full journey from early years to the IB in one place. Ask early about waiting lists in the most popular year groups.

UWC Thailand

UWC Thailand is in Thalang, in the quiet north of the island, about a 10-minute drive from Phuket International Airport. It is an IB school with over 400 students from more than 60 nationalities and, in its own words, no dominant culture. Mindfulness and social and emotional learning sit at the core of the timetable, and the school offers boarding as well as day places. Its profile lists support for students with ADHD and autism spectrum needs, and it holds a 5.0 rating from 5 reviews.

Who it fits: globally mobile families who value service, wellbeing and a mixed community as much as grades. The school accepts applications throughout the year but asks families to visit first, so build a campus visit into your relocation trip.

HeadStart International School

Founded in 2005, HeadStart sits on a 6-acre campus in Vichit, central enough to reach from most parts of the island. It is a British school for ages 2 to 18 with around 800 students from 45 nationalities. The Early Years Foundation Stage covers ages 2 to 4, primary follows the Cambridge International curriculum, students sit IGCSEs at 16, and the sixth form offers a choice between A levels and BTEC. A university preparation programme, U-Prep, guides older students through applications. It holds a 5.0 rating from 4 reviews.

Who it fits: families aiming for UK or Commonwealth universities, and teenagers who would do better on a vocational BTEC route than on a fully academic one. That BTEC option is rare on the island.

Kajonkiet International School, Phuket

Kajonkiet, known locally as KIS, is a co-educational day school for children aged 2 to 18 on a 15-rai site in Kathu. Teaching is in English, and parent reviews describe a British curriculum, creative lessons and free after-school clubs. It holds a 4.5 rating from 4 reviews. Being in Kathu, it is a practical option for families living towards Patong or on the west coast.

Who it fits: families who want a British education in a smaller, day-school setting. Check exactly which clubs are included in the fees, since free activities can noticeably lower the real cost of a school year.

QSI International School of Phuket

QSI Phuket is also in Kathu, on Chalermphrakiat Ror. 9 Road, and teaches in English from the early years through high school. It belongs to the Quality Schools International network and follows a mastery learning model: each unit has clear objectives, and students progress when they have shown they have mastered them. The school was designed for children of families who stay in a country for a year or more, so short stays are part of its DNA. Its rating is 3.4 from 5 reviews, more mixed than the others on this list, although some parents are very positive about the individual pacing.

Who it fits: children who have moved between systems and have gaps to fill, or families on shorter postings. Ask to see how mastery reports translate into grades for university applications.

School fees in Phuket and what they really include

None of the five schools publishes fees on its profile, so the figures below are rough ranges based on typical published fee schedules on the island. Fees are quoted in Thai baht, usually per term or per year.

Nursery and early years: roughly 250,000 to 500,000 THB a year (about US$7,000 to $15,000).
Primary: roughly 400,000 to 750,000 THB a year.
Lower secondary: roughly 550,000 to 900,000 THB a year.
IGCSE, A level and IB years: roughly 650,000 to 1,000,000 THB a year, and more at the top campuses or with boarding.

On top of tuition, budget for:

A one-off application or registration fee and, at many schools, a larger enrolment or capital fee for new families.
A refundable deposit or bond, often held until your child leaves.
School bus transport, which can be a meaningful extra if you live far from campus.
Lunches, uniforms and sports kit.
External exam fees for IGCSE, A level or IB, plus residential trips.
Devices, since many secondary sections run a bring-your-own-laptop policy.

On visas: the DTV covers the remote-working parent, but children usually need their own dependant visa or a student (ED) visa arrangement. Schools handle this differently, so ask the admissions office what they can sponsor and which documents they need before you book flights.

Shortlisting advice for Phuket

Decide where you will live after you shortlist, not before. Rental leases on the island are often signed in a hurry, and families then discover a 45-minute drive along Thepkrasattri Road twice a day. Pick two or three schools that fit your child, then look for housing in the zone between them.

Match the exit route to your plans. If you expect to stay through graduation, compare the final two years first: IB at UWC Thailand or BISP, A levels or BTEC at HeadStart, the British route at Kajonkiet, or the QSI diploma. If you might leave after a year or two, prioritise schools with a curriculum your next country will recognise easily.

Visit in term time and ask about turnover. Island schools tend to see more student movement than city schools. Ask how many children joined and left the year group in the past year, how new arrivals are buddied up, and how many teachers are on their first contract. Those answers tell you more about day-to-day life than a polished prospectus.

Frequently asked questions

Which international schools in Phuket offer the IB Diploma?

UWC Thailand in Thalang is an IB school from the early years upwards, and British International School Phuket in Koh Kaew lists the IB among its programmes for older students. HeadStart offers A levels or BTEC instead, so families set on the IB should focus their visits on the first two and confirm current subject choices with each school.

Can my child join an international school in Phuket mid-year?

Yes, mid-year entry is common on the island because so many families relocate outside the usual August start. UWC Thailand, for example, accepts applications throughout the school year but asks families to visit first. Popular year groups can have waiting lists, so send recent school reports and contact admissions as soon as your move is confirmed.

Which part of Phuket is best to live in for international schools?

Koh Kaew, Vichit and Kathu are the most practical bases, because BISP, HeadStart, Kajonkiet and QSI all sit in the centre of the island. Families choosing UWC Thailand often live in Thalang or around Bang Tao. From Rawai or Kata in the south, expect 40 minutes or more to the northern campuses at peak times.
