Bilingual Schools in Phuket: A 2026 Guide for Expat Families

Last reviewed: September 2026 by David from ISA. Fee ranges are indicative; always confirm with the school.

Families searching for bilingual schools in Phuket are usually balancing two goals. They want a strong English education that travels well, and they want their children to become comfortable in Thai, the language of friends, neighbours and daily life on the island. Some also want Mandarin, which many Phuket schools now teach from the early years. The good news is that the island has a wider choice than its size suggests. The challenge is that "bilingual" means very different things from one campus to the next.

This guide explains the bilingual models you will find in Phuket, the schools worth visiting first, what they cost in Thai baht and the questions that reveal how a school really uses each language.

Why Phuket has become a bilingual schooling hub

Phuket is no longer only a holiday destination. Remote workers, hospitality professionals, entrepreneurs and retirees with young families have settled across the island, and Thai families from Bangkok have moved south for a calmer life. Most schools sit in three areas: the Kathu and Chalong corridor in the centre, the Thalang and Bang Tao area in the north near Laguna, and Phuket Town in the east. Traffic on the main roads can be slow in high season, so living close to school matters more than on paper.

Thai law also shapes the offer. Thai nationals who attend international schools must follow Thai language and culture lessons set by the Ministry of Education, and many schools open those lessons, in adapted form, to foreign children too. As a result, even English-medium schools on the island usually give Thai a real place in the week.

Bilingual models you will find in Phuket

• English-Thai bilingual schools: subjects are split between English and Thai, and students can follow either an international or a Thai track. This is the closest thing to true bilingual education on the island.
• English-medium international schools with Thai and Mandarin: the British, IB or American curriculum is taught in English, with Thai and Mandarin as daily or near-daily language lessons.
• Montessori and early years settings: small nurseries and kindergartens that mix English and Thai through play, useful up to age six.
• Multilingual boarding and IB schools: a diverse student body where several home languages are supported alongside English.

Bilingual and multilingual schools to shortlist

Kajonkiet International School, Phuket

Kajonkiet International School is part of a long-established Thai school group and is one of the island's clearest bilingual options. English and Thai share the curriculum, and the school suits families who want their children to be at ease in both languages, or who are unsure whether they will stay in Thailand long term. Fees are among the more moderate on the island.

HeadStart International School

HeadStart International School follows the British curriculum in English and runs Thai and Mandarin programmes for students of different levels. It is popular with families who want a British education with serious language support at a mid-range price.

British International School Phuket

British International School Phuket is the island's largest and longest-running international school, with a big campus, boarding and a British curriculum that leads to IGCSE and the IB Diploma. Thai and Mandarin are taught across the school, and the student body brings many other home languages. It is a strong choice if you want breadth, sport and a well-known name for the next move.

UWC Thailand

UWC Thailand is part of the United World Colleges movement and teaches the IB from primary to Diploma. Its multilingual community, mindfulness programme and focus on service make it attractive to families who see languages as part of a wider international outlook.

How much bilingual schools in Phuket cost

Fees depend heavily on the model you choose. As a rough guide for the 2026 school year:

• Bilingual English-Thai schools: roughly THB 250,000 to 450,000 a year.
• Mid-range international schools: roughly THB 350,000 to 650,000 a year.
• Premium international and IB schools: roughly THB 700,000 to over 1,000,000 a year in the senior years.

Extras to add to your budget:

• Application and assessment fees, often THB 5,000 to 10,000.
• One-off enrolment or capital fees, which can reach THB 100,000 or more at premium schools, and refundable deposits.
• School bus, lunches, uniforms and trips.
• Exam fees for IGCSE, A level or IB, and boarding if you need it.

Keep one practical rule in mind: most Phuket schools quote fees per term, and the first invoice usually bundles tuition, enrolment fees and deposits together, so the first year is always the most expensive.

Practical advice for families

Ask for the language split in writing. Request the weekly timetable for your child's year group and count the hours in each language. A school with one Thai lesson a week and a school where half of the subjects are taught in Thai are both called bilingual in marketing, but they produce very different results.

Match the track to your plans. If you might stay in Thailand for many years, a real English-Thai model gives your child access to Thai universities and friendships. If you expect to move on within a few years, prioritise the international curriculum and treat Thai as an enriching extra.

Visit in term time. Many families arrive during the high season holidays. Try to see schools while classes are running, and ask to sit in on a Thai or Mandarin lesson to judge the level and the teaching style.

Support the home language too. Children who learn in English and Thai can lose fluency in their family language surprisingly fast. Ask whether the school runs mother tongue clubs or after-school classes, and keep reading and speaking the home language at home, especially in the first two years.

Frequently asked questions

Are there truly bilingual English-Thai schools in Phuket?

Yes. Kajonkiet International School is the clearest example, with English and Thai sharing the curriculum. Most other schools on the island are English-medium international schools that teach Thai and Mandarin as language subjects. If you want real bilingual instruction rather than language lessons, ask how many subjects are taught in Thai in your child's year.

Do foreign children have to learn Thai at Phuket international schools?

Thai nationals must follow Thai language and culture lessons set by the Ministry of Education. For foreign children the rules are more flexible, but most schools in Phuket still offer Thai for non-native speakers and often make it part of the core timetable in primary. Check how many lessons a week are included.

How much does a bilingual school in Phuket cost per year?

Bilingual English-Thai schools cost roughly THB 250,000 to 450,000 a year, while premium international and IB schools can pass THB 1,000,000 in the senior years. Add enrolment fees, deposits, transport, lunches and exam fees, which make the first year noticeably more expensive than the following ones.
