Phuket is no longer just a holiday island. It hosts one of Asia's most concentrated clusters of British boarding-style international schools alongside long-established American and IB options. In 2026, international school fees in Phuket span from THB 250,000 per year at smaller bilingual schools to over THB 1,200,000 for the senior years at flagship British boarding schools. This 2026 guide breaks down what to budget realistically, including the hidden capital levies, boarding fees and IB exam costs that catch first-time expat families off guard.
Phuket's international school market in 2026
The island runs schools across three families:
- British: British International School Phuket (BISP) and HeadStart International School lead the cluster. Cambridge IGCSE and A Level or BTEC pathways.
- International Baccalaureate: UWC Thailand (Phuket campus) runs the full IB continuum (PYP, MYP, DP) with a strong scholarship culture.
- American and bilingual: QSI International School of Phuket and the International School of Phuket follow US accreditation routes.

Frequently asked questions
Why are Phuket international school fees lower than Bangkok?
Bangkok hosts more top-tier global flagship schools (NIST, ISB, Patana) with higher land and staff costs. Phuket is competitive but charges roughly 15-25 percent below comparable Bangkok schools at the day-school level.
Do Phuket schools accept the Thai Bachelor's degree pathway?
Yes. IGCSE / A Level, IB DP and US high school diploma routes from all the schools listed are recognised for entry into Thai universities (Chulalongkorn, Mahidol, Thammasat) and globally.
Is there scholarship support for English-speaking expat families?
Yes, but limited. UWC's needs-based DP scholarships are competitive and prioritise diversity. BISP and HeadStart award merit-based scholarships of 10-50 percent for high academic, sports or arts achievement.
