Key facts
| Address | 306, Khok Kruat, Mueang Nakhon Ratchasima, Nakhon Ratchasima 30000 -- roughly 13 km south-west of the old city. The school's own footer gives 30000; both independent directories give 30280. We publish the school's own |
| Founded | August 2015, with a Christian, Gospel-centred mission -- per the school's own official site |
| Where it stops | DISPUTED, and the school's own site disagrees with itself. Its "Who We Are" page says Nursery to Grade 12; its mission page says it "currently" runs to Grade 10 with Grade 11 planned; doris says Grade 11 now with Grade 12 planned for 2026-2027. Ask for the current year-group list in writing |
| Leaving qualification | Intended to be the IB Diploma. Whether the Diploma Programme is AUTHORISED or a CANDIDATE is unresolved between the school's own page and the directories -- candidate status carries no guarantee that authorisation follows. Check the IB's own school register before enrolling a child who needs it |
| Curriculum | Early Years and Primary on an American-influenced foundation, then the IB Middle Years Programme from Grade 6, then the Diploma Programme for the sixth-form years |
| Accreditation | ACS WASC, in the school's own words. Separately: the IB is an examination AUTHORISATION (MYP authorised; DP disputed), EARCOS is a MEMBERSHIP the school describes correctly as such, and ONESQA and ISAT appear only as footer logos with no supporting statement on the site |
| Boarding | Yes -- a three-floor boarding house on campus with a cafeteria, a study room on each floor, bathrooms shared between three same-gender boarders, and 5-day or 7-day options. The only boarding house in Korat city. Own site says Grades 6 and above; a directory says Grades 4 and above |
| Religious character | Evangelical Christian. The school's founding vision is to transform Thailand's future leaders "through the Gospel" and its stated vision is "a world shaped by Christlike global citizens". The boarding programme includes Bible reading, devotions and a Sunday service. No statement of faith document and no denominational affiliation is published -- the site never explains the "Wesley" name, so a Methodist link is an assumption, not a published fact |
| Admissions | Entrance assessment required of all new pupils -- MAP Growth in reading and maths plus reading fluency, with writing added from Grade 3. Results valid three months. A weak English result places a child in ELL or after-school support rather than barring entry. Rolling admissions year-round, mid-year joiners accepted |
| Student body | Students from 14 countries and staff from 13 countries per the school's own site; 3 languages taught; class sizes run small, historically averaging around 10 students |
| Tuition | The school links its own current tuition and boarding fee schedules from its admissions page. BAANLYY publishes no per-school fee figures -- they change annually and a stale number is worse than none. Use the school's own schedule |

Overview
Wesley International School sits at 306, Khok Kruat, roughly 13 km south-west of Korat's old city, and was founded in August 2015 with a Christian, Gospel-centred mission to engage and transform the future leaders of Thailand. It is small by design: around 120 pupils, classes averaging about 10 and capped around 20, teaching assistants in class, and pupils from roughly 14 or 15 nationalities depending on which source you read. It runs Early Years and Primary on an American-influenced foundation before moving into the IB Middle Years Programme, for which it is an authorised IB World School, and it states its own accreditation as ACS WASC.
Two things about WIS are more useful to a relocating family than any of that. First, it is the only school in Korat city with a boarding house -- a three-floor building on its own campus, 5-day and 7-day, with meals and laundry provided. Guides to Korat, including BAANLYY's own until this update, have routinely told families the nearest boarding is 84 km west at Khao Yai. It is not.
Second, the school is mid-expansion into a sixth form and its own website has not settled on how far that has got. Its "Who We Are" page says Nursery to Grade 12 with the IB Diploma Programme; its mission page, on the same site, says it "currently" runs to Grade 10 with Grade 11 planned. The doris directory's current record calls the Diploma Programme a candidate programme for 2026-2027 and puts the school at Grade 11 now. The International Schools Database's school-verified record lists ages 2 to 18 with the IB Diploma and AP as leaving qualifications. We publish all four positions rather than picking one, because candidate status is not authorisation and a family enrolling a sixteen-year-old is buying something different depending on the answer. BAANLYY is not affiliated with WIS and takes no paid placement in this guide.
Who it's for
WIS suits families who want a Christian-values-based education combined with a genuine, internationally recognised IB pathway through the Diploma Programme, small class sizes, and a diverse, multinational student body, at a more moderate tuition range than many fully international schools. Families wanting a Singapore/British curriculum with a longer track record and broader age range instead often consider Anglo Singapore International School's Korat campus; families wanting a Seventh-day Adventist Christian alternative consider Korat Adventist International School (KAIS).
Location & getting there
WIS sits at 306, Khok Kruat, on the south-western approach to Korat -- roughly 13 km from the old city, and about 8 km in a straight line from Korat Adventist International School, which is on the opposite, north-western approach. Families sometimes shortlist the two together as "the small Christian schools in town" and assume one address will serve both; it will not. Distances are straight-line, computed from the coordinates the International Schools Database publishes for each campus, so the road distance is longer.
Nakhon Ratchasima has no rail-transit network and none planned. A school bus service is recorded but no routes are published on the school's own site, so ask for the route in writing. For families outside a workable commute, the campus boarding house is the alternative -- which is unusual for a school this size and is the main reason WIS reaches beyond the city.
FAQ
When was Wesley International School (WIS) founded?
In August 2015, with a Christian, Gospel-centred mission, per the school's own official site.
How far does WIS actually teach — and does it run the IB Diploma?
This is genuinely unsettled, and the disagreement is inside the school's own website. Its 'Who We Are' page describes WIS as an IB World School offering both the Middle Years Programme and the Diploma Programme, from Nursery through Grade 12. Its mission page, on the same site, still says the school 'currently' runs to IB MYP 5 (Grade 10) and plans to start Grade 11. The doris directory's current record describes WIS as an authorised MYP school and a CANDIDATE for the Diploma Programme for 2026-2027, running to Grade 11 now with Grade 12 planned for 2026-2027. The International Schools Database's school-verified record lists ages 2 to 18 with the IB Diploma and AP as leaving qualifications. Candidate status is not authorisation and carries no guarantee that authorisation follows. Ask WIS for its DP authorisation date and check it against the IB's own school register before enrolling a child who needs the Diploma.
Does WIS have boarding?
Yes, and it is the only boarding house in Korat city -- a fact missing from most guides to the area, including BAANLYY's own until this update. The school's boarding page describes a three-floor building on its own campus with a cafeteria on the ground floor, a study room on every floor, and bedrooms sharing a private bathroom between three same-gender boarders, with meals and laundry provided. Both 5-day and 7-day options are offered. This is a real dormitory rather than a homestay placement. The school's own page says boarding starts at Grades 6 and above; the International Schools Database says Grades 4 and above -- confirm the entry year directly.
Is WIS accredited?
It states in its own words that it is accredited by ACS WASC. It is separately an authorised IB World School for the Middle Years Programme -- an examination authorisation, not an accreditation. EARCOS is described by the school correctly as a membership. ONESQA and ISAT logos appear in the site footer with no supporting statement anywhere on the site, so we report them as displayed rather than as verified claims. These are four different kinds of thing and are routinely collapsed into one word.
Where is WIS located?
306, Khok Kruat, Mueang Nakhon Ratchasima -- roughly 13 km south-west of the old city, on the opposite approach from Korat Adventist International School and about 8 km from it in a straight line. The school's own footer gives the postcode as 30000; both independent directories give 30280. We publish the school's own.
