British — the English National Curriculum blended with the IB Primary Years Programme, then Cambridge IGCSE, then the IB Diploma · Samnak Thon, Ban Chang
The school BAANLYY previously placed in another province. St. Andrews Green Valley is not in Bang Lamung, Sriracha or Chonburi: its owner Cognita publishes the address as Samnak Thon, Ban Chang District, Rayong 21130, the isbi directory gives 1 Moo 7 on the Ban Chang–Makham Khu Road with coordinates in Ban Chang, and the International Baccalaureate's own school record is titled "St. Andrews International School, Green Valley, Rayong". It is a countryside campus in the same district as Garden and REPS, and it gives Rayong province something our guide said the province did not have — a second full IB pathway, and the only IB Primary Years Programme in the province. Its published philosophy rests on eco-literacy, personalised learning and holistic education; the Head of School is Charles Grayhurst.
1 Moo 7, Ban Chang–Makham Khu Road, Samnak Thon, Ban Chang, Rayong 21130
Ban Chang district, Rayong — inland from Ban Chang town on the Makham Khu road, and a few minutes from the Pala cluster where Garden and REPS sit. Convenient, in Cognita's own words, "for the communities of Pattaya and Rayong", but materially closer to Rayong. There is no rail. Any guide — including our own until this revision — that describes this school as being between Pattaya and Sriracha, or as a natural choice for the Laem Chabang and Sriracha corporate community, has it geographically backwards.
Cognita — a London-headquartered global group operating schools across Europe, Latin America, the Middle East and Asia, including three other St. Andrews campuses in Bangkok. This makes St. Andrews Green Valley the only international school in Rayong province outside the Garden/REPS group, and therefore the only genuinely independent second opinion on a Rayong shortlist.
A low-rise campus of around 30 rai in open country near the Green Valley golf area — notably green even by Eastern Seaboard standards. The setting is the selling point and also the constraint: it is a countryside school, not a town one. Facilities reported by directories include swimming, golf, football, basketball, athletics, gymnastics and cricket, with ballet, drama, sailing and horse riding among the activities.
Leaving qualification: IB Diploma, taught on campus.
A day school. Cognita classifies it as "Day School, International School" on its own corporate page, and the isbi directory records zero full boarders and zero weekly boarders against its roll. If you need boarding in Rayong, Garden's dozen beds are the only international provision in the province, and Rugby School Thailand and Regents Pattaya run substantially larger programmes an hour north.
Reported inconsistently: the isbi directory records 370 day pupils (190 boys, 180 girls) and no boarders; other sources give around 400 students from 35 nationalities, and around 450 from 30-plus nationalities. All three describe a mid-sized school, materially smaller than the large Pattaya campuses. We publish the spread rather than pick one.
Families who want the IB from the primary years rather than only in the sixth form — this is the province's only PYP school — and families who want a countryside campus with space. It is the natural second quote for anyone whose first call was Garden, precisely because it is the one school in the province under different ownership. Dutch-speaking families should look here first, in Thailand generally and not just in Rayong.
