This campus is in Saraburi province, not Ayutthaya. Ayutthaya has no international school of its own — we tried to disprove that and could not. It appears on BAANLYY’s Ayutthaya guide because it is one of the four international schools within practical reach to the east, a direction every other guide to Ayutthaya schooling omits entirely in favour of sending families south to Bangkok.
A Montessori day school in rural Nong Don, aligned to AMI and NAMTA standards and teaching in English from the early years through an adolescent programme. The smallest and least conventional of the four Saraburi international schools, included because a complete list is more useful than a curated one -- and flagged clearly as day-only and without a named leaving qualification, which together decide the question for most families reading from Ayutthaya.
Also known as: JWM Saraburi.
Which direction it is from Ayutthaya
Ayutthaya’s defining schooling problem is not distance, it is direction. Guides written from Bangkok outwards assume the only road out is south. It is not.
EAST, into rural Nong Don -- off the main trunk roads and the least convenient of the four from Ayutthaya. Day school only, so distance is not negotiable here the way it is at SJMIS.
Where this school stops
Adolescent / high school level, reported to 18. Given the small scale of the campus, the age the school offers and the age it currently has a viable class in are different questions -- this is the Krabi cohort-reality lesson, and it applies here more than to the other three.
What a leaver actually holds
The curriculum label and the leaving qualification are different things. For a family that may move country again, this line is the decision — and a blank cell is itself a finding.
None named. A Montessori adolescent programme is a pedagogy, not an examination route, and the school's network material does not identify an external qualification. If your child needs IGCSEs, A-Levels, an IB Diploma or a US diploma, ask specifically how this campus delivers them before assuming it does.

The curriculum pathway, stage by stage
- Pre-primary / toddler and Children's House.
- Primary.
- Adolescent programme, described by the school's network as running through to high school age.
Accreditations, authorisations & affiliations
Three different claims, routinely collapsed into one. A whole-school accreditation (WASC, CIS, NEASC, Cognia) assesses the school itself. An examination-board authorisation (College Board, Cambridge, IB) means it may enter pupils for those exams. A membership or affiliation is neither. And “none named” is a fourth state, distinct from “not accredited”.
- ALIGNED, not accredited: the curriculum is described as aligned with AMI (Association Montessori Internationale) and NAMTA standards. Alignment to a pedagogical standard is a weaker claim than whole-school accreditation and should not be read as equivalent to the WASC accreditation held by SJMIS and AIMS.
- No whole-school accreditation from WASC, CIS, NEASC, Cognita or an equivalent body is named.
Boarding
For an Ayutthaya family this is not a lifestyle question, it is the question. Without boarding or a van route, a Saraburi school is a daily drive across a provincial boundary.
None. This is the one school of the four Saraburi group described as a day school only -- which for an Ayutthaya family is the decisive limitation, because without boarding it is a daily drive into Nong Don or nothing.
Who it suits
Families genuinely committed to Montessori who are living close enough to Nong Don to make a daily run, typically with younger children. It is a poor fit for a family that needs an examination route or that is relying on boarding.
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 two independent censuses disagree on the age floor -- one records ages from 3, the other from 18 months. We report both rather than pick.
- Day school with no boarding, which rules it out for most Ayutthaya families as a practical matter regardless of its merits.
- No leaving qualification is named anywhere we could find. For a family that may move country again, that is the decision, not a detail.
- The school is one campus of a wider John Wyatt Montessori network. Facts published about the network as a whole do not automatically hold for the Saraburi campus -- confirm staffing, age groups actually running, and facilities for this site specifically.
- Neither census publishes a roll figure for this campus and the school does not either, so its actual size is unknown to us.
Ask every school in the Ayutthaya catchment this
- Before you accept a Bangkok commute, price the eastern option. Saraburi has four international schools at a broadly comparable radius from Ayutthaya, three of which board, at published fees in the low hundreds of thousands rather than Bangkok's four hundred thousand to over a million. Every guide sends you south; check east before you sign a lease.
- Ask Saint John Mary for the current school van route list, in writing. Whether a route reaches the Wang Noi or Bang Pa-in side of Ayutthaya is the single fact that decides whether the strongest international school within reach is a day school or a boarding school for you.
- When a school says boarding, ask whether it means a dormitory on campus or a homestay placement with a partner family. They are different products with different supervision, and directories record both as "boarding: yes".
- Ask what qualification a leaver actually holds, and who awards it. Three of the four Saraburi schools run American programmes and only one of them also hosts the College Board, SAT and TOEFL testing on site. One names no leaving qualification at all.
- Ask whether the final years are taught on campus or partly online. One of the four is built around blended learning by design and says so; that is a feature for some families and a deal-breaker for others.
- For any Thai school's English Program, ask how many periods a week are genuinely delivered in English, and what a non-Thai-speaking child faces at admission. Cost is not access: Thai EP and state-school entry usually runs through an examination sat in Thai on a fixed national timetable.
- Before shortlisting any school you found in an English-language listicle, apply the four-part existence test: does it have its own domain, a findable street address, a phone that answers, and does its own homepage carry any closure or rebranding notice? The most syndicated page on Ayutthaya schooling currently recommends a school that does not exist.
BAANLYY does not rank, endorse or accept payment from schools. Facts on this page are compiled from John Wyatt Montessori — Saraburi Campus's own published material 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, accreditation status and campus details directly with the school. Visit the official John Wyatt Montessori — Saraburi Campus page →
