American, taught from a biblical worldview — ACSI & WASC accredited · Hang Dong district, south of Chiang Mai city (37-acre campus)
Grace International School (GIS) was established in 1999 by missionaries Gene and Sherrie Foltz to provide an affordable, quality K–12 education for the children of international Christian workers based across Southeast Asia. The school sits on a 37-acre campus in Hang Dong district, south of Chiang Mai, and teaches over 500 students from families representing more than 85 organisations serving in 40-plus countries. GIS delivers an American curriculum taught from a biblical worldview, with core subjects including Bible, language arts, mathematics, science, social studies and foreign languages, and is accredited by both the Association of Christian Schools International (ACSI) and the Western Association of Schools and Colleges (WASC).
A 37-acre campus in Hang Dong — one of the larger school sites in the province, with the room for sports fields and the boarding-style community facilities its mission implies.
Getting there: No urban rail. Grace sits in Hang Dong, south of the city — typically 20–30 minutes from the Old City and quicker from Mae Hia, Saraphi or the Canal Road corridor, longer from Mae Rim or San Sai in the north. The southern suburbs are the sensible place to live for this run, and the Hang Dong corridor has the condo and house supply to make that easy.
Chiang Mai has no urban rail — no BTS, no MRT, no commuter metro. The city's railway station serves intercity trains to Bangkok, and the long-discussed Chiang Mai light-rail scheme remains unbuilt, so every school run here is a car, a motorbike, a red songthaew, a Grab or the school bus. Read the Chiang Mai getting-around guide and the Chiang Mai area guides before you commit to a neighbourhood.
Grace International School (GIS) does not publish detailed smoke-season filtration information that we could verify from primary sources, so we are not going to imply provision that may not exist. That is not a criticism of the school — most Chiang Mai schools handle this well and simply do not document it publicly — but it does mean you must ask directly. The due-diligence list below tells you exactly what to ask.
Northern Thailand's burning season runs roughly February to April, when agricultural burning and forest fires push Chiang Mai high into the global air-quality rankings — IQAir placed the city among the ten most polluted in the world on 4 March 2026, with AQI above 150 and PM2.5 the dominant pollutant. For a family with young children this is a legitimate school-selection criterion, not a footnote. Our Chiang Mai air-quality guide covers the season in full.
How a child progresses through the school, stage by stage:
Accreditation is the closest thing to an objective quality signal in international schooling — it means an outside body has inspected governance, teaching and safeguarding. BAANLYY does not rank schools, so this is what Grace International School (GIS) and its accrediting bodies publish, not our verdict:
Scale: Over 500 students, drawn from families serving with more than 85 organisations across 40-plus countries — an unusually mission-focused community even by the standards of Chiang Mai's faith-based schools. Roll and nationality figures move every year and schools report them differently — treat these as indicative and ask the admissions office for the current numbers.
Its stated purpose is the education of the children of international Christian workers, and the community reflects that. Families outside that world should look closely at whether the biblical-worldview curriculum and the community's centre of gravity are what they want; families inside it will find the deepest such network in northern Thailand.
This is our editorial read for relocation planning, not a ranking or a recommendation — and no school pays to appear on BAANLYY. Visit shortlisted campuses before you decide.
The southern corridor is the natural catchment. The BAANLYY area guides for this run:
Check the school's bus catchment before you sign. Chiang Mai's international schools cluster in two distinct belts — the northern one around Mae Rim and San Sai, and the far larger southern one through Hang Dong, Mae Hia and Saraphi — and picking a home in the wrong belt turns a fifteen-minute run into a daily hour.
BAANLYY deliberately does not publish per-school tuition figures: they change annually, schools publish their own current schedules, and a stale number is worse than none. Take this list to the admissions office:
