Phuket has rapidly evolved from a beach holiday destination into one of Thailand's main international school hubs. Long-stay families, digital nomads on Long Term Resident visas and Asia-based expats relocating from Hong Kong and Singapore have driven demand for British, IB and American curriculum schools across the island. The result is a small but high-quality cluster of international schools competing for limited places.
If you are planning a 2026 move to Phuket, this step-by-step guide walks through the admissions process: timelines, required documents, language assessments, fees in Thai Baht, and how to maximise your chances at the most competitive schools.
How the Phuket admissions calendar works
Phuket international schools follow the August academic year. Most run rolling admissions but cluster decisions around three windows:
- Main wave (October to February) for August entry — the strongest window for limited-place year groups.
- Spring wave (March to May) for August or January entry — many schools assess candidates here for second-semester moves.
- Late wave (June onwards) for families relocating last-minute, mostly handled through waitlists.
Because Phuket has fewer schools than Bangkok, popular year groups (Year 7, Year 12 IB Diploma) often close by Christmas. Apply by November where possible.
Required documents
Plan to gather these documents at least 60 days before you submit:
- Apostilled birth certificate (translated into Thai or English if not already)
- Last two years of school reports translated into English
- Vaccination record matching Thailand's national requirements
- Copies of passport and Thai visa or LTR / Elite Visa documentation
- Proof of address in Phuket or rental contract
- Reference letter from current head teacher for Year 7 and above
- Standardised test scores (MAP, CAT4, ISEE) where requested
Several schools also request a writing sample, parent interview and a short student-led video call before in-person assessments.
Top international schools in Phuket and their admissions process
British International School Phuket
British International School Phuket (BISP) is the largest and longest-established British curriculum school on the island, offering EYFS through to A Levels and IB Diploma in the upper school. Admissions include CAT4 testing and English readiness for non-native speakers from Year 3 onwards. BISP also runs an extensive sports academy programme that operates as a separate admission stream.
UWC Thailand
UWC Thailand is part of the global United World Colleges network and follows a full IB Continuum (PYP, MYP, Diploma) on a campus near Mai Khao. Admissions are aligned with UWC values and require an interview that explores how each child fits the international, mission-driven student body.
HeadStart International School
HeadStart International School follows the British curriculum from Pre-Nursery through Year 13. The school admits on a rolling basis and offers strong English-as-an-additional-language support, making it a frequent first stop for families whose children are not yet native English speakers.
QSI International School of Phuket
QSI International School of Phuket follows an American mastery-based curriculum and is part of the global QSI network. Admissions require MAP testing in maths and reading, plus a parent interview. The school is small (under 250 students), which means waitlists move quickly when families relocate.
Kajonkiet International School Phuket
Kajonkiet International School (KIS) follows a Cambridge International curriculum from Pre-K through Y13 and is one of the more affordable international schools on the island. Admissions include an English assessment and an interview with the head of school.
Language assessments and EAL support
Most Phuket international schools teach in English and expect children entering from Year 3 onwards to be functional in the language. Tools commonly used:
- WIDA or Oxford Online Placement for English readiness
- CAT4 for cognitive and reasoning benchmarks (used by BISP and HeadStart)
- MAP Growth for maths and reading levels (American curriculum schools, including QSI)
If your child is not yet native in English, look for schools with embedded EAL support — BISP, HeadStart and Kajonkiet are the strongest in this area. Most schools charge an additional THB 50,000 to THB 120,000 per year for individualised language support.
Fees and registration costs
Fees in Phuket sit below Bangkok and well below Singapore, but are still significant:
- Application fee: THB 3,000 to THB 8,000
- Capital levy / enrolment fee: THB 80,000 to THB 250,000
- Annual tuition: THB 350,000 to THB 750,000 for primary; THB 600,000 to THB 950,000 for upper secondary including the IB Diploma
- Lunch, transport, uniform: THB 60,000 to THB 120,000 combined
Always ask whether your offer includes the capital fee or if it is invoiced separately at signing.
Practical admissions tips
- Apply to two or three schools in parallel — competition for limited Year 7 and IB Diploma seats is real, especially at BISP and UWC.
- If you are still abroad, request a virtual tour and Zoom interview rather than waiting to visit in person. The best schools fill quickly between November and February.
- Confirm whether the school accepts Long Term Resident (LTR) visa documentation — most do, and several offer fee discounts for LTR holders.
- Test the school commute. Phuket roads are unpredictable, and a 12 km school can mean 45 minutes during high season traffic.
- Cherng Talay (north-west) and Rawai (south) are the densest expat areas. Choose your home based on the school, not the other way round.
