Most expat families arrive in Phuket, open the school fees page for BISP, and quietly revise their monthly budget downwards. At ฿550,000–฿730,000 per year per child, a premium international school education can easily be the single largest monthly expense in Phuket — more than rent, more than health insurance, more than everything else combined for some families.
Kajonkiet International School doesn't often appear in the first wave of recommendations because it operates in a different tier entirely. Fees from ฿60,000 per year. Located in Phuket Town rather than on the west coast expat corridor. Bilingual Thai-English curriculum rather than IB or British. But for the right family, it's a genuinely solid choice — and the difference in annual fees could fund a real estate deposit.

The Real Story on Fees
Kajonkiet's fees are genuinely low by international school standards. At ฿60,000–฿100,000 per year, you're looking at ฿5,000–฿8,300 per month — less than a mid-range one-bedroom apartment in Rawai. The comparison with other schools is stark:
| School | Annual Fees (2026) | Monthly Equivalent | Curriculum |
|---|---|---|---|
| Kajonkiet | ฿60,000–฿100,000 | ฿5,000–฿8,300 | Bilingual Thai-English |
| QSI Phuket | ฿160,000–฿300,000 | ฿13,300–฿25,000 | American (Mastery) |
| HeadStart | ฿240,000–฿330,000 | ฿20,000–฿27,500 | British / Cambridge |
| BIS Phuket | ฿300,000–฿420,000 | ฿25,000–฿35,000 | British IGCSE/A-Level |
| UWC Thailand | ฿400,000–฿600,000 | ฿33,000–฿50,000 | IB |
| BISP | ฿550,000–฿730,000 | ฿45,800–฿60,800 | IB |
Additional fees to budget: registration (฿5,000–฿10,000), uniforms (฿3,000–฿5,000), and activity fees. These are substantially lower than the capital levies charged by premium schools (BISP capital levy alone can be ฿150,000+).
Curriculum: What Bilingual Actually Means
Kajonkiet's bilingual programme means students receive instruction in both English and Thai. This is not the same as a purely English-medium international school. Core academic subjects are taught in English; Thai language, Thai culture, and some supporting subjects are in Thai.
For children planning to integrate long-term into Thai society — if you're raising children who will work in Thailand, marry Thai partners, or simply grow up here — the strong Thai language foundation is a genuine long-term advantage. Children leave Kajonkiet with conversational and academic Thai fluency that BISP or UWC graduates rarely achieve.
For children who will return to English-speaking education systems in three to five years, the bilingual model requires careful thought. The English academic rigour at Kajonkiet is lower than at HeadStart, BIS, or the IB schools. Transition back to a Year 9 UK classroom after Kajonkiet secondary may require remedial work in some subjects.
⚠ Honest Assessment
Kajonkiet is excellent value for its price point, but the academic preparation for European and American university entry is less rigorous than BISP, UWC, HeadStart, or QSI. If your child will need competitive IB or A-Level qualifications for university entrance, Kajonkiet should not be the final secondary school. Many families use Kajonkiet for primary years and transfer to a premium school at secondary level — this is a sound strategy.
Location: Phuket Town Realities
Kajonkiet's Phuket Town location is its second major differentiator from the other schools. For families living in Phuket Town or nearby Thalang, it's genuinely convenient. For the large expat community in Rawai, Bang Tao, Kata or Kamala, the school run adds 30–45 minutes each way, which can mean 60–90 minutes of driving per day.
If you're choosing between Kajonkiet from Bang Tao and QSI or HeadStart in Rawai, the commute difference is significant. Factor real journey times (including Phuket Town morning traffic on Chaofah Road) into your decision.
Insider Tip
Kajonkiet's Phuket Town location works best for families who have also chosen to live in Phuket Town — which is genuinely underrated as an expat base. Affordable rents (฿12,000–฿25,000/month for decent apartments), walkable to markets and restaurants, close to the immigration office and most government services. The school + Phuket Town living combination makes the overall budget significantly more manageable than beach-area living + premium school.
✓ Strengths
- Exceptionally affordable fees (฿60k–100k/yr)
- Strong Thai language development
- Good for long-term Thailand residents
- Phuket Town location is central and practical
- Smaller class sizes than larger commercial schools
- No capital levy burden
- Good for primary years before transferring
✗ Weaknesses
- Lower English academic rigour at secondary level
- Not ideal for competitive UK/US university entry
- No IB Diploma or Cambridge A-Levels
- Less international community (predominantly Thai families)
- Location inconvenient for west coast beach areas
- Limited international extracurricular programme
- Fewer English-speaking peer group options at secondary
Who Chooses Kajonkiet?
From speaking with current and former Kajonkiet families, there are broadly three profiles who make this choice work well:
Long-term Thailand residents: Families who have lived in Thailand for years, are not planning to move to another country, and genuinely want their children to be bilingual Thai-English speakers. A Thai-integrated upbringing is a feature, not a compromise.
Primary-only strategy: Families who use Kajonkiet for years 1–6 (saving ฿1.5M–฿2M in school fees versus BISP over those years) and then transition to a premium school at secondary level when academic rigour becomes more important. This is a financially intelligent approach if executed with clear planning.
Budget-constrained expats: Families where the ฿500,000–฿700,000 annual fees of premium schools are genuinely unaffordable, but who want English-medium education rather than Thai public school. Kajonkiet provides a meaningful step up from the Thai state system at an accessible price.
Admissions Process
Kajonkiet's admissions are more straightforward than premium schools. The process involves application, academic assessment, and payment of registration and first-term fees. There is generally no waiting list pressure comparable to BISP or HeadStart for most year groups.
The school year follows the Thai academic calendar — starting in May/June — with an international programme track that may accommodate September starts for some year groups. Contact the school directly for the current intake schedule.
