Education & Schools in Koh Samui

International education options for expat families - from British curriculum to IB programs

Education Overview

Koh Samui has a growing international school scene catering to the increasing expat family population. While options are more limited than Bangkok or Chiang Mai, the island offers quality British and international curricula suitable for primary through secondary education. Most expat families choose between ISS International School and Lamai International School as the main established options.

School fees range from ฿200,000 to ฿450,000 per year depending on grade level and school. This is lower than Bangkok international schools but higher than Chiang Mai. The island's small size creates tight-knit school communities where families know each other well. For university-age students, most leave the island for Bangkok, Singapore, or Western universities.

Tips for Expat Parents

📅Apply Early

International schools have limited spaces, especially for secondary grades. Apply 6-12 months in advance if possible. Waiting lists are common for popular year groups.

🏫Visit in Person

Schedule campus visits before committing. Talk to current parents, observe classes, and assess facilities. School websites often look better than reality on small islands.

💰Budget Comprehensively

Tuition is just the start. Add registration fees, uniforms, supplies, transport, activities, and trips. Real annual cost is 20-40% higher than listed tuition.

📚Plan for Secondary

Limited secondary options on Samui. If you have younger children, research secondary school plans early. Many families relocate or switch to boarding schools at Year 10.

🌏Understand Curriculum Transitions

British curriculum may differ from home country. Understand how IGCSEs and A-Levels translate for university applications in your target country.

👨‍👩‍👧Get Involved

Small island schools rely heavily on parent involvement. Volunteering strengthens community, helps your child settle, and gives insight into school operations.
