Greenacre International School was founded in 2017 by Dara Nagle, Lindsey Archbold and Viroj Junthong, after the closure of a nearby school left a gap in Koh Samui's provision. The campus sits at 108 Moo 2 in Na Mueang, in the quieter southern interior of the island near the Na Mueang waterfalls — a genuinely different part of Samui from the Bophut and Chaweng cluster. It describes itself as an inclusive school for multilingual children and follows the English National Curriculum from the Early Years Foundation Stage through to a two-year Cambridge IGCSE programme in Years 10 and 11. Environmental awareness is the school's stated organising idea, formalised in an “Environmentality” programme, and it runs the Duke of Edinburgh's Award alongside after-school clubs and a wellbeing programme. Experienced staff provide additional support for students with English as a second language.
Where the campus actually is
108 Moo 2, Na Mueang, Ko Samui, Surat Thani 84140
No rail exists anywhere on Samui, and Greenacre is the most rurally sited of the island's schools — inland in Na Mueang, in green country near the waterfalls, well away from the Chaweng–Bophut belt where ISS and PBISS sit. That distance is the whole point for some families and a deal-breaker for others; drive it before you commit.

The curriculum pathway, stage by stage
- Early Years Foundation Stage
- Primary — Key Stages 1 and 2
- Key Stage 3, Years 7–9 (ages 12–14) — 10 subjects including English, mathematics and science
- Key Stage 4, Years 10–11 (ages 14–16) — the two-year Cambridge IGCSE programme, with every student expected to sit at least six subjects including English, mathematics, science and humanities
What happens after 16
Greenacre ends at IGCSE, in Year 11 at about age 16. There is no sixth form. That is not a criticism — it is a planning fact, and the school is clear about it. Every Greenacre family will change school for A-levels or the IB: on-island that means ISS, PBISS or Windfield, and off-island it means the mainland, Phuket or Bangkok. Decide the second school before you enrol in the first, because moving a 16-year-old across the country is a much larger decision than moving an 11-year-old across the island.

Scale & provision
The school does not publish a roll figure, so we do not quote one. Facilities on campus include a library, an ICT room, a science laboratory and a swimming pool.
No boarding is advertised on the school's own website — treat Greenacre as a day school.
Who it suits
Families based in the quieter southern half of the island who want a small, environmentally-minded British school and are content to plan a second school for the sixth-form years.
What we could not verify — and where sources disagree
We publish these openly rather than smoothing them over. A school guide that hides its uncertainty is not much use to a family making a decision this big.
- The school's secondary page names the two-year Cambridge IGCSE programme, while its site footer also links Pearson Edexcel International GCSEs. Both authorisations appear genuine; ask which board each individual subject sits with.
- The fee link on the school's homepage still points at a document on a former domain. Ask admissions for the current schedule in writing.
Ask every Koh Samui school this
- Ask whether the sixth form is taught on campus or online. On Samui this is the single highest-stakes question: of the three schools running A-levels, two describe their post-16 route as blended or hybrid learning on their own websites. Ask exactly which subjects are taught by on-site specialist staff, which are delivered remotely, and who supervises the student during study periods.
- Ask whether the year group your child needs actually runs this year. Island cohorts are small, and a stage can appear on a website while the class itself is not staffed or not filled. Ask how many children are currently in that specific year group.
- Drive the school run at 07:30, not at midday. Samui is a ring island served by one main road; the Chaweng and Lamai stretches back up badly at school and commuting times, and straight-line distance on a map is close to meaningless.
- Ask what the school bus actually covers. Provision varies enormously here -- one school advertises transport across the island, another describes its service as limited, and some run none at all. The bus catchment quietly decides which neighbourhoods are realistic for you.
- Ask which exam board each subject sits with, and where the examinations are physically taken. Several Samui schools hold authorisations from more than one board, and island logistics matter for exam sessions.
- Request the school's own current fee schedule in writing, including registration, deposit, uniform, bus, lunch and trips. We do not publish per-school fees because they change annually.
BAANLYY does not rank, endorse or accept payment from schools. Facts on this page are compiled from Greenacre International School's own official website and independent cross-checks, and we deliberately publish no per-school fee figures — they change annually and a stale number is worse than none. Always confirm current admissions, fees, year groups and campus details directly with the school. Visit the official Greenacre International School website →
