The island's one Ministry of Education-licensed international school -- UK Early Years, then a Canadian curriculum from Grade 1 through 12, in Sala Dan.
The International School of Asia, Koh Lanta is, per its own official site, the island's sole international school licensed by Thailand's Ministry of Education. It serves children from age 2 through 18, teaching a UK Early Years curriculum for Nursery through Kindergarten and then a Canadian curriculum from Grade 1 through Grade 12, in English alongside Thai language classes. The school frames its approach around a "seven Cs" framework -- Compassion, Computing, Communication, Collaboration, Critical Thinking & Learning Skills, Citizenship, and Creativity -- and maintains a sister-school partnership with Shinjo Higashi High School in Japan.

Early Years follows the UK Early Years framework, play-based and foundational for Nursery and Kindergarten-age children. From Grade 1 onward, the school follows a Canadian curriculum through to Grade 12, split into Elementary and High School stages on its own site. As a single-campus school covering the full Pre-K to Grade 12 range, it is a genuinely different option from the wider, multi-campus international-school clusters in Phuket or Bangkok -- families weighing it against those options should factor in class sizes, subject breadth at senior grades, and university-counselling depth, none of which BAANLYY could independently verify beyond what the school's own site describes.
Third-party school-directory data puts 2025/2026 annual fees at roughly THB 181,960 to THB 267,330 depending on grade level -- BAANLYY could not locate this figure published directly on the school's own site, so treat it as indicative rather than official, and request the school's own current fee schedule and any registration, uniform or exam-fee add-ons before budgeting. The school's own site lists a dedicated Admission page, an online admission form, a Fee Policy, and Visa Assistance for relocating families.
The school sits in Sala Dan (Saladan), Koh Lanta's main town and the island's ferry/bridge-access hub -- a practical, central location for families based anywhere on the island's more populated west coast.
