KIS is one of the names a family meets early when researching the international schools in Phuket and wants a recognised British education without the top tier price of the island's most expensive schools. It opened around 2011 under the long established Kajonkietsuksa education group and has grown into a full through school running from pre nursery to sixth form on a single green campus in Kathu.
The draw of KIS is the combination of a known Cambridge route, a relatively quiet inland setting and a fee band that undercuts British International School Phuket and UWC Thailand. That places it among the practical choices for relocating families who want English medium teaching and a clear path to UK style qualifications.

Curriculum and academics
KIS teaches a single coherent British spine in English from the early years to sixth form. The youngest children follow the Early Years Foundation Stage, after which primary and lower secondary run on the British curriculum through the Cambridge framework. Pupils sit Cambridge IGCSE examinations at around 16 across English, mathematics, the sciences, humanities and creative subjects, then move into a Cambridge AS and A Level sixth form in Years 12 and 13.
Languages are a visible part of the offer, with Thai, Chinese and Japanese taught alongside the English medium core, and the school runs English as an additional language and special educational needs support for pupils who need it. Families who want the broader, holistic continuum of an IB World School will find KIS is a more conventional examined British route, which is the right fit when the goal is a familiar UK style progression to IGCSE and A Level.

Kajonkiet International School Phuket (KIS) fees
Kajonkiet International School Phuket (KIS) fees sit in the mid tier of the island's market. Our guide to international school fees in Phuket places its published annual tuition at roughly THB 220,000 in the early years rising to about THB 480,000 in the senior and sixth form years, with primary in between. That is comfortably below the top tier schools and within reach of many relocating families.
Tuition is not the whole bill. KIS charges a one off admission fee and a small application fee, with school transport billed separately and priced by zone for one way or round trip journeys across the island. Families needing English language support should budget for an additional annual EAL charge, and sixth form examination entry lands in the final two years. Use our fee calculator to fold tuition and these extras into a single annual figure, and confirm the current published fees with the admissions office, since the bands above come from our market tracking rather than an invented price list.
Admissions
As an international school, KIS accepts applications through the year rather than to a single fixed deadline, with the main intake aligned to the August start of the academic year. Entry is by application, recent school reports and an age appropriate assessment that gauges English level and readiness for the relevant year group, with older applicants assessed for the IGCSE or sixth form programme.
Families relocating mid year should contact admissions early, as individual year groups can fill in the popular early years and primary classes. Useful documents to have ready are recent school reports, passports and visa paperwork and any prior assessment records. The school advises on which year group fits a child's age and prior schooling.
Location and who goes there
KIS occupies a green 15 rai site in the Kathu valley, off Pra Phuket Kaew Road, roughly fifteen minutes from Phuket Town and thirty to forty minutes from the western beaches. The inland setting gives the school space for dedicated music and sports facilities and a calmer environment than the busier coastal strips, at the cost of a longer commute for families based around Bangtao, Laguna or Rawai.
The intake is genuinely mixed, drawing Thai and international families from across the island, which suits parents who want their child in a broad community rather than a single nationality bubble. For how Kathu compares with the northern beaches and the town, the Phuket city hub sets out the map, and our roundup of the best international schools in Phuket shows where KIS sits among the alternatives.
