Jirasart Witthaya School.

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 at all -- the reason it belongs on this page despite not being an international school.

Where this school stops

Lower secondary, Mathayom 3 -- roughly age 15. There is no Mathayom 4-6 and no sixth form, so every family here plans a second school for the final three years. That is the single most decision-relevant fact on this page and it is not a criticism of the school; it is simply where it ends.

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 Ministry of Education lower-secondary completion. Not IGCSE, not a US high school diploma, not the IB. A child leaving here at 15 re-enters the Thai system, an English Program stream at a Thai upper-secondary school, or an international school elsewhere -- and the third route usually means an entrance assessment.

Where the campus actually is

Central Ayutthaya, within the town rather than out on the highway corridors. Confirm the pick-up arrangement directly; we did not find a published route map.

The curriculum pathway, stage by stage

• Pre-kindergarten and kindergarten in Thai, with English taught by foreign staff.
• Primary (Prathom 1-6) -- the English Program stream teaches English, Science and Mathematics in English while the rest of the timetable follows the Thai national curriculum.
• Lower secondary (Mathayom 1-3), where the school's own provision ends.

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”.

• Licensed private school under the Thai Ministry of Education -- the operative recognition for a school of this type.
• No international whole-school accreditation is claimed, and none should be expected: this is a Thai private school with an English stream, not an international school.

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. This is a day school.

Who it suits

Families who want their child educated in Ayutthaya itself, in a large and long-established school with real foreign-teacher capacity, and who are comfortable with a Thai-curriculum spine. Realistically the strongest local option for younger children, and a genuine bridge while a longer-term decision is made.

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 scale is reported at over 2,000 pupils with around 35 foreign teachers. Both figures come from the school's own recruitment material rather than an audited return, so treat them as indicative of size, not precise.
• The English Program covers English, Science and Mathematics. It is not an English-medium education -- the remainder of the timetable is Thai. Ask exactly how many periods a week your child would sit in English before assuming it is a substitute for an international school.
• The school's name is romanised at least three ways across directories (Jirasart Witthaya, Jirasartwitthaya, Jirasastravidhya). Search the Thai name if an English search fails.
• As with every Thai school's English Program, cost is not access: entry can involve an assessment conducted in Thai. Confirm what a non-Thai-speaking child would actually face before budgeting on the fee alone.

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.
