British (National Curriculum) + IB PYP, IGCSE & IB Diploma · Samnak Thon, Ban Chang (Rayong — ~45 min south of Pattaya)
St. Andrews International School, Green Valley sits on a 30-rai campus surrounded by pineapple fields, forest and golf courses in open country at Samnak Thon in Ban Chang district — which is in RAYONG province, not Chonburi, and roughly 45 minutes south of Pattaya. Its owner Cognita publishes the address as Ban Chang District, Rayong 21130, the isbi directory records 1 Moo 7 on the Ban Chang–Makham Khu Road, and the IB's own school record is filed under Rayong; the International Schools Database files it under Pattaya, which is where the widespread Chonburi misplacement comes from. It is part of the global Cognita group of schools. Its founding year is reported inconsistently across sources — variously the mid-1990s, 1996 or 1999 — so we are not going to state one rather than guess; what is consistent is that it is one of the Eastern Seaboard's more established international schools. It is unusual in the region for running the IB Primary Years Programme alongside the British National Curriculum in the primary school, then IGCSEs, then the IB Diploma.
A 30-rai low-rise campus in open country, notably green even by Eastern Seaboard standards, adjacent to the Green Valley golf area. The setting is the selling point and also the constraint — it is a countryside school, not a city one.
SOUTH of Pattaya, not north of it — this is the fact most listings get backwards, and BAANLYY's own pages did until August 2026. The campus is inland from Ban Chang town on the Makham Khu road, in Rayong province, roughly 45 minutes from central Pattaya and only minutes from Garden International School and REPS at Pala. That geography makes it a natural choice for the Rayong, Map Ta Phut and U-Tapao corporate community rather than for Sriracha and Laem Chabang, and a real daily drive for anyone living on the Pattaya beach strip. There is no rail. Check the bus catchment before you commit to a neighbourhood: this school's practical catchment runs south into Rayong province, not north up Sukhumvit.
There is no urban rail anywhere on the Eastern Seaboard — no BTS, no MRT, no metro. The State Railway's eastern line calls at Pattaya but it is a sparse intercity service, not a school run, and the Bangkok–U-Tapao high-speed rail scheme is not in service. Baht buses cover the beach strip and do not usefully reach the inland campuses where most of these schools sit. Every school run here is a car, a school bus, a motorbike or a Grab — so the neighbourhood you choose and the bus route you qualify for matter more in Pattaya than in almost any Thai city. Read the Pattaya getting-around guide and the Pattaya area guides before you sign a lease.
How a child progresses through the school, stage by stage:
Accreditation is the closest thing to an objective quality signal in international schooling — it means an outside body has inspected governance, teaching and safeguarding. BAANLYY does not rank schools, so this is what St. Andrews International School, Green Valley and its accrediting bodies publish, not our verdict:
Boarding: We could not verify a boarding provision at the Green Valley campus from primary sources, and we are not going to imply one. Treat it as a day school unless the admissions office tells you otherwise — and if you need boarding on the Eastern Seaboard, Regents and Rugby School Thailand both run substantial programmes.
Scale: Around 450 students from more than 30 nationalities — a mid-sized school by regional standards, materially smaller than Regents or Rugby. Roll and nationality figures move every year and schools report them differently — treat these as indicative and ask the admissions office for current numbers.
Families who want a continuous IB-flavoured education from the primary years through to the Diploma, rather than a British primary bolted to an IB sixth form; families based in or posted to Rayong, Ban Chang, Map Ta Phut or U-Tapao, for whom this is a local school rather than a cross-province one; and families who want a smaller, countryside school. Less suitable if you live in Pattaya itself or further north towards Sriracha, where the daily drive becomes the dominant fact of the arrangement.
This is our editorial read for relocation planning, not a ranking or a recommendation — and no school pays to appear on BAANLYY. Visit shortlisted campuses before you decide.
This school is in Rayong province, so living for it means living south towards Ban Chang rather than in Pattaya proper — our Rayong guides are the relevant ones:
Confirm the bus catchment before you sign. Pattaya's international schools are strung along a 60-kilometre corridor across three districts and two provinces — Nongprue in the city, Pong and Khao Mai Kaew inland, Green Valley towards Sriracha, Bo Win beyond it and Ban Chang in Rayong. Choosing a home on the wrong side of that corridor turns a ten-minute run into a daily hour each way.
BAANLYY deliberately does not publish per-school tuition figures: they change annually, schools publish their own current schedules, and a stale number is worse than none. Take this list to the admissions office:
