Every year, families land in Phuket planning "a few months" and discover the same thing: the island part is easy, and the school part decides everything. Phuket has a genuine international-school scene — good enough that some families extend a one-term experiment into years — but enrolment works on terms, waiting lists and paperwork, not on turning up with a backpack in week one. If you're planning a 3- to 12-month family stay, here is how the system actually works, what it costs, and which schools will take your child for a single term at all.

The Main Options, by Area

British International School Phuket (BISP) — Koh Kaew, east of Phuket Town. The island's flagship: British curriculum through to IB, big green campus, serious sports and boarding facilities. Ages roughly 18 months to 18 years. The premium name and the premium fees, in that order.

UWC Thailand — Thalang, near the airport road. Part of the United World Colleges movement, IB from early years to diploma, with a strong outdoors/mindfulness ethos and a notably international parent body. Popular with families who want the IB pathway recognised worldwide.

HeadStart International School — two campuses (Phuket Town / Vichit, and Cherng Talay). British curriculum, well regarded for primary years, and the Cherng Talay campus puts it in reach of the Bang Tao/Laguna family belt. Often the first name mid-budget families compare everything else against.

Kajonkiet International School (KIS) — Kathu. British-style curriculum in the island's middle, handy for Patong-side families (Kathu is 15 minutes over the hill), generally a step below BISP/UWC on fees.

The bilingual and Thai-private tier — Kajonkiet's other campuses, Darasamuth, Phuket Thai Hua and similar. These teach a Thai curriculum with heavy English programmes at a fraction of international fees. Many long-stay families — especially those with a Thai parent, or planning years rather than terms — find them the sensible middle: local friends, Thai language, fees that don't consume the whole stay budget.

What a Term Actually Costs

Fees vary by year group (primary is cheaper than secondary everywhere) and are quoted per term or per year. As a 2026 orientation, in baht:

• Top tier (BISP, UWC): roughly ฿450,000–฿750,000 per year for primary, more for secondary and IB years.
• Mid tier (HeadStart, KIS): roughly ฿250,000–฿450,000 per year.
• Bilingual/Thai private: roughly ฿60,000–฿180,000 per year — a different world.
• On top, everywhere: a registration/enrolment fee (often ฿50,000–฿150,000 at the top tier, sometimes partly refundable as a deposit), plus uniforms, lunches, bus, after-school activities and exam fees. Always ask for the full schedule of fees, not just the tuition line.

Most schools run three terms (roughly Aug–Dec, Jan–Apr, Apr/May–Jun/Jul depending on the calendar they follow — British and IB calendars differ slightly). For a 3- to 12-month stay, you are usually buying one to three full terms: schools bill by the term, not by the month, and partial-term refunds are not a thing.

Will They Take a Child for One Term?

This is the question that shapes a short family stay, and the honest answer is: it depends on the year group and the waiting list.

• Primary years with space: usually yes — mid-tier schools especially will enrol for a single term if a seat exists, and they're used to expat churn.
• Exam years (IGCSE, IB Diploma): often no, or reluctantly — syllabuses sequence across two years and schools protect results.
• Nursery/kindergarten: the most flexible of all; some offer genuinely short enrolments.
• Waiting lists exist at the popular names even mid-year. Email admissions before you book flights; a "we have space in Year 4 from January" answer is worth more than any agent's optimism.

School is only half the day — pick your base so the other half works too.

Trials, Visits and the Paperwork Pack

Most schools offer a campus tour and admissions meeting; some offer a trial day (a few charge for assessment instead). Book the tour during term time so you see a real school day, and ask about class sizes and teacher turnover while you're walking — the honest answers come mid-corridor, not from the brochure.

Have this pack scanned and ready before you apply anywhere:

• Child's passport (valid well beyond the stay) and birth certificate
• Your passports and visa pages
• Previous school reports — usually the last two years, in English or translated
• Vaccination/health record
• Passport photos of the child (schools specify the count)

Applications are mostly online now; assessment is typically an English/maths placement plus an informal interview for younger children. Allow two to six weeks from application to a confirmed seat — another reason the school email goes out before the flight booking.

The Visa Knock-On for Parents

A child enrolled at a recognised international school can support a parent's guardian arrangement tied to the education visa route — one parent per child, with financial proof (a Thai bank balance requirement applies) and paperwork the school's admissions office handles every term for other families. Rules and balances change, and the school's guidance beats any blog's — including this one — but know the pathway exists before you assume the whole family rides on tourist entries. For bilingual and unlisted schools, the education route may not apply the same way; ask admissions directly.

Choosing Where to Live, Once School Is Fixed

School run geography is the real decision. BISP and Phuket Town schools pull families toward Kathu, Koh Kaew and Town itself; HeadStart Cherng Talay and the west-coast life pull toward Bang Tao and Laguna; a Patong base works best with Kathu schools (KIS) at 15–20 minutes, and gets punishing as a daily run to Thalang. Fix the school first, then choose the neighbourhood inside a 20-minute school-run radius — families who do it the other way round spend their Phuket mornings in traffic, remembering this paragraph.
