The first and only university laboratory school in Phra Nakhon Si Ayutthaya province, established in 1985 and attached to Phranakhon Si Ayutthaya Rajabhat University. A Thai-medium secondary school listed here for completeness of the local picture.
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.
In Ayutthaya. No commute.
Where this school stops
Mathayom 6, around age 18.
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.
Thai upper-secondary completion.
Where the campus actually is
96 Pridi Banomyong Road, Pratu Chai, Phra Nakhon Si Ayutthaya 13000
Pridi Banomyong Road, Pratu Chai, on the university side of town.

The curriculum pathway, stage by stage
- Secondary, Mathayom 1-6, operated as the teaching-practice school of Phranakhon Si Ayutthaya Rajabhat University.
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”.
- Operated under Phranakhon Si Ayutthaya Rajabhat University. Public-sector oversight, not international accreditation.
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 published. Day school.
Who it suits
Thai-fluent families already in the university orbit. Included for completeness rather than as a realistic route for a newly arrived foreign child.
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.
- A laboratory school exists partly so that trainee teachers can practise in it. That is a normal and well-understood arrangement in Thailand, but it is a structural difference from a conventional school and worth asking about directly.
- Reported scale is around 780 pupils across Mathayom 1-6. The figure comes from a third-party record, not the school.
- Instruction is in Thai.
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 Laboratory School of Phranakhon Si Ayutthaya Rajabhat University'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.
