Choosing a school is the biggest decision most expat families make when relocating to Phuket. After six years here and dozens of conversations with expat parents, I've tried to give you the honest picture — not the brochure version. Here's what actually differentiates these schools.
Phuket's International Schools — Full Profiles
BISP — British International School Phuket (Koh Kaew)
BISP is Phuket's largest international school and the automatic first-choice comparison for most expat families. Located in Koh Kaew (between Phuket Town and the airport area), it runs the British curriculum from Reception through Year 13, offering both IB Diploma and A-Levels at senior level — one of few schools in Thailand to offer both pathways.
The campus is impressive: a full-size sports complex, two pools (25m main + learner), dedicated theatre, design labs and expansive playing fields. For families that value sports, BISP is a strong choice — it competes nationally in football, swimming, tennis and athletics.
IB Diploma average points: approximately 33–34/45 (strong; global average is 30.24). A-Level results have been consistently strong with many students gaining places at UK Russell Group universities. The school's ESL (English as a Second Language) programme is robust — relevant for non-native English-speaking children.
UWC Thailand (Formerly UWC Mahidol) — Thalang
UWC Thailand (part of the global United World Colleges network) is Phuket's most academically rigorous school and attracts students from across Southeast Asia and beyond. Located in Thalang in the north of the island, it runs IB MYP (Years 7–10) and IB Diploma (Years 11–12) exclusively — no British curriculum, no A-Levels.
IB Diploma average points: approximately 36–38/45 — significantly above both the BISP average and the global mean. Many UWC graduates access top-tier universities globally (UK, US, Europe). The school's international student body (60+ nationalities) creates a genuine multicultural environment that suits globally-minded families.
Important caveats: UWC Thailand does not have a primary school (the youngest year is Year 7 / age 11). For younger children you will need another school first. The campus is smaller and the focus is purely academic and IB-oriented — less emphasis on sports facilities than BISP.
HeadStart International School — Rawai
HeadStart is the choice for expat families in the south of the island (Rawai, Nai Harn, Kata/Karon) who want an IB education without the BISP price tag. Located in Rawai, it runs IB PYP (Primary Years Programme) through IB MYP and IB Diploma — meaning a consistent IB journey from age 3 to 18.
The school is smaller and more community-focused than BISP — many parents cite the close-knit atmosphere as a major attraction. Class sizes are smaller (typically 15–20 vs BISP's 20–25). IB Diploma results are good rather than exceptional (approx 31–33 average), positioning it below UWC but above many Thai private schools.
Fees are considerably lower than BISP and UWC — a significant factor for self-funded expats rather than those on education-package corporate contracts. The Rawai location is convenient for families living in south Phuket.
QSI International School Phuket — Koh Kaew
QSI (Quality Schools International) follows a US-based curriculum rather than IB, making it the go-to choice for American expat families or those who specifically want US college preparation. Located near Boat Lagoon in Koh Kaew, QSI runs from Preschool through Grade 12.
The school uses a mastery-based learning approach rather than traditional grade progression — students advance when they demonstrate mastery of content rather than at year-end. This suits some learning styles very well and can be challenging for others. Class sizes are small.
For families moving on a short posting (1–3 years), QSI's international network (35+ schools worldwide) makes transferring between QSI campuses seamless — curriculum is consistent globally. Less suitable for families planning long-term Phuket residency targeting UK or European universities.

Admissions — Timelines and Process
Phuket school admissions work on rolling intake but popular year groups (particularly Years 7–10 at BISP and UWC) can have waiting lists of 12–18 months. The general process:
- Initial enquiry — Contact the admissions office directly (school websites have online enquiry forms). Request a virtual or in-person tour.
- Application — Submit application forms, previous school reports, passport copies and teacher references. Application fees of ฿5,000–15,000 are typically non-refundable.
- Assessment — Most schools do an informal assessment in English and Maths for children joining Year 3 and above. UWC requires a more formal entry assessment.
- Offer — If accepted, a formal offer letter is issued. Registration fees (฿40,000–150,000) are due to secure the place.
- Visa timing — An Education Visa (ED Visa) is available for students enrolled in accredited schools — useful for extending family visas. Your visa agent in Phuket can arrange this.
Thai Curriculum Schools — An Alternative Worth Considering
Not every expat child attends a full-fee international school. Kajonkietsuksa International Programme (Phuket Town) offers Thai curriculum with strong English-language instruction at significantly lower fees (฿80,000–150,000/year). Some expat families — particularly those planning 3+ years in Thailand — find this an excellent option for primary age children who will benefit from Thai language immersion and a diverse local social environment.
