International schools in Phuket: a guide for families relocating in 2026

The school decision is often the thing that determines where in Phuket a family settles, and it gets made with less information than it should. Schools charge enrolment fees before giving you much of it. Waiting lists move unpredictably. And the Facebook group advice is a mix of legitimate experience and outdated posts from three school managements ago.

This is a factual guide to what exists in 2026, what it costs, and what to think about before you commit.

The landscape

Phuket has more international school options than you’d expect for a Thai island — around a dozen offering English-language instruction across British, American, and IB frameworks. The permanent resident community is large enough to fill classrooms year-round rather than cycling with tourist seasons. Most of the established schools sit in the north and central parts of the island, which is also where the majority of the foreign resident population lives.

Thai government schools operate in Thai and are designed for Thai children. They are not a realistic option for children who do not speak Thai, though some families with younger children — typically pre-school or early primary age — and longer-term plans have made it work.

British curriculum

British International School Phuket (BISP) is the school that comes up first in almost every conversation about international education in Phuket. Around 900 students from 60+ nationalities, with a campus in the Koh Kaew area east of the main island population. British National Curriculum from EYFS through Year 13, with both A-levels and the IB Diploma — the only Phuket school offering that combination. On-site boarding is available.

What parents consistently mention: the sports facilities (50m competition pool, full-size sports hall, athletics track) and the breadth of extracurriculars across a dozen disciplines. These are cited as the deciding factor more often than the academics. What comes up less positively: fees that rise annually, and communication with admin that can be inconsistent across departments.

Fees run from approximately ฿290,000 per year at Early Years to ฿820,000–860,000 at IB Diploma level. Boarding adds ฿450,000–650,000 per year. Average class size is 20–22 students.

BCIS (Berda Claude International School) in Chalong is the newest purpose-built campus on the island, backed by International Schools Partnership (ISP) — a global group operating 80+ schools. British National Curriculum leading to Cambridge IGCSE. Still establishing its track record, but the facilities are modern and class sizes are small. Families in the south of Phuket who would rather not put their children on a bus heading north every morning should look at BCIS early.

Fees run from approximately ฿180,000 to ฿450,000 depending on year group.

IB schools

UWC Thailand (United World College Thailand) sits in Thalang adjacent to the Thanyapura sports complex — a relationship that matters for sports-focused families, since students access Thanyapura’s swimming, athletics and tennis facilities. Part of the global United World College network of 18 schools, it’s the only UWC in Southeast Asia. Full IB continuum: PYP, MYP, and Diploma Programme. Around 500–600 students from 70+ nationalities.

What sets UWC apart: the diversity is deliberate rather than incidental, with students from scholarship programmes alongside fee-paying families. The sustainability and mindfulness curriculum integration is more embedded than at other schools. Parents praise the community and the IB depth. What comes up: high fees, and a social-issues emphasis that some families find heavy.

Fees run from approximately ฿460,000 to ฿850,000 per year. Boarding available at additional cost. Class sizes of 18–22.

HeadStart International School serves the Bang Tao and Cherng Talay corridor from its main campus near Laguna, with a second campus at Chaofah (closer to Phuket Town) — the only Phuket international school offering that geographic flexibility. IB Primary Years Programme combined with Cambridge IGCSE and A-Level at secondary level.

Parents consistently mention the warm community feel and the approachability of teachers. The bilingual English-Thai programme tracks are stronger here than elsewhere. What comes up: older facilities at the city campus, and limited extracurricular options compared to BISP.

Fees run from approximately ฿140,000 at Early Years to ฿420,000 at secondary level. Maximum 25 per class, actual averages around 18–22.

Kajonkiet International School (KIS) in Kathu is part of the Kajonkietsuksa group — one of Phuket’s oldest school networks, founded in 1954, running both Thai and international streams. Cambridge curriculum leading to IGCSE and A-Level. The most affordable international school option on the island.

What parents value: the price combined with decent academics and genuine Thai cultural integration. What comes up: less rigorous academics compared to BISP, basic facilities, and some classes with a high Thai student ratio that limits English immersion.

Fees run from approximately ฿120,000 at Early Years to ฿350,000 at secondary. Student-teacher ratio around 10:1 to 12:1.

American curriculum

QSI International School of Phuket in Kathu is the only American-curriculum school on the island, accredited by the Middle States Association (MSA). That accreditation matters for American families needing transcript recognition for US college applications. Around 150–200 students — small and intentionally intimate.

QSI uses a mastery-based learning model rather than traditional grading: students demonstrate competence before progressing, which means no one advances with gaps. It’s part of a global QSI network (37 schools in 30+ countries), making transfers between QSI schools seamless — useful for diplomat and expat families who move frequently.

What parents highlight: the individual attention (class sizes of 8–15 students, teacher ratio around 6:1 to 8:1) and the tight-knit community. What comes up: limited course offerings at upper secondary because the school is small, and fewer sports and extracurricular options.

Fees run from approximately ฿280,000 to ฿520,000 per year.

Fees: the real picture

Annual fees across Phuket’s established international schools run from approximately ฿120,000 at the lower end (KIS, younger year groups) to ฿860,000 at BISP’s IB Diploma level. Most schools charge:

• An application fee (non-refundable, typically ฿2,000–5,000)
• An enrolment or capital levy (often ฿50,000–150,000, sometimes refundable on departure)
• Annual tuition fees (as above)
• Possibly a building fund or development contribution

Add uniforms, books, activities, transport, and lunch: a realistic all-in annual cost per child is 20–30% above the headline tuition figure.

Some schools offer sibling discounts. Most do not have meaningful financial assistance programmes — UWC Thailand is the exception through its scholarship network. The fees are the fees.

What to think about before you decide

Curriculum continuity matters. If your child will return to a home country school system, matching the curriculum simplifies that transition. A British child in an American school, or vice versa, can land back home a year behind or a year ahead in unexpected subjects. The IB has the advantage of international portability.

Location and commute. Many schools offer transport by school bus, but routes and costs vary. A daily commute of 45–60 minutes each way in Phuket traffic is not unusual for families in the south trying to reach northern schools. This matters more than most parents expect at the start. HeadStart’s two-campus model and BCIS’s southern location exist partly to address this.

Class sizes and year group sizes. Some schools have one class per year group at secondary level. Some have three. A small year group can feel like a tight community or a narrow social pool depending on your child. QSI’s intimate size is a feature for some families and a limitation for others.

The extracurricular offer. This varies significantly. BISP’s sports programme is the strongest on the island. UWC Thailand’s access to Thanyapura adds swimming, athletics and tennis. Smaller schools may not have the numbers for competitive team sports but can offer strong individual or arts programmes. Ask specifically what’s on offer for your child’s interests.

Waiting lists. Popular year groups at established schools can have waiting lists of 6–12 months. If you are relocating with children in Year 7–9 at BISP or Year 10–11 anywhere, contact schools before you finalise your move dates.

Visits. Every school in Phuket offers school tours. Do at least two or three. The gap between a school’s marketing and its actual culture is visible within 30 minutes of walking around during a normal school day.

Other schools worth knowing about

Finnway International School Phuket (Koh Kaew) — a Finnish-curriculum school that opened around 2023, using the Finnish education model (play-based, student-led learning). Small and new, but a different approach entirely.

International School of Phuket (ISP) (Rawai) — a smaller British/Cambridge school, budget-friendly, serving the south.

Oak Meadow International School (Chalong area) — small, Montessori-influenced.

Homeschool and online school

A growing number of Phuket resident families use online schooling or homeschool co-ops, particularly since COVID accelerated the shift. We haven’t covered this community in detail yet — if you’re part of it or considering it, we’d like to hear from you at phuketcommunity.com/submit.

What nobody tells you

International school fees are a significant part of the Phuket cost-of-living calculation for families and are often under-estimated at the planning stage. Two children at secondary level at one of the larger schools is ฿1,000,000–1,300,000 per year in fees alone. This changes the financial picture of relocating to Phuket substantially.

The school also partly determines the social life of both the children and the parents. The BISP parent community is large and active. UWC Thailand attracts a globally-minded crowd. Smaller schools have tighter, quieter parent groups. Neither is better; they are different. Think about which suits you.
