International schools in Chiang Rai.

The short version

Chiang Rai province has three international schools, and a family relocating to Chiang Rai city is realistically choosing between two of them. CRIS in Rimkok, north of the centre, runs ages 3 to 18 with Advanced Placement in the high school and is the only school in the province with boarding. CRICS in Ban Du has been going since 1998, starts at Kindergarten age 5, and graduates students on a 22-credit American high-school diploma. Both are WASC-accredited. The third, One Hope, is in Mae Sai on the Myanmar border, about an hour north — a genuine school with genuinely open admissions, but not a city commute and not yet running a high school.

Two things surprise most families and neither is usually stated up front: there is no secular international school in Chiang Rai — all three have a Christian character of some kind — and every school run here is a drive, because the province has no rail and no city-wide school bus network. Below: the schools, what they are accredited by, where each one stops, where to base yourself, and how burning season bears on the decision. For day-to-day budgeting pair this with the Chiang Rai cost-of-living guide, and use the Chiang Rai hub to match a neighbourhood to your school.

The three schools

A starting point, not a ranking. Each name links to a full profile.

Where each school starts — and where it stops

In a field this small, the age range matters more than the prospectus. A family with a three-year-old and a family with a fifteen-year-old are not choosing from the same list here.

Two consequences worth planning around. CRICS has no preschool — it begins at Kindergarten, age 5 — so a family with a toddler is looking at CRIS or a local Thai nursery for the first two years. And One Hope has no upper years yet: its oldest cohort is Grade 8 in 2026/27, with Grade 9 promised from 2027 and a grade added annually after that. Enrolling a child there today means planning the secondary years separately unless the build-out keeps pace with them.

Accreditation

This is the clearest line between the province’s schools, and it is rarely drawn. Accreditation is what makes a transcript legible to a university admissions office in another country.

Neither city school is an IB World School and neither runs a British curriculum — if you need IB, IGCSE or A-levels, the nearest real options are in Chiang Mai. Note also what CRIS’s membership of WIDA International signals in combination with its ELD programme: a structured approach to teaching children who arrive without fluent English. CRICS handles the same need through an ELL assessment at admission and its own support services. If your child will be learning in English for the first time, ask both schools to walk you through exactly how that is staffed.

American curriculum, three ways — and all three Christian

All three schools teach an American-style curriculum, and they are not interchangeable. CRIS follows Common Core for English and Maths, Next Generation Science Standards for science and AERO for social studies, adds Thai, Chinese and ICT, and offers Advanced Placement courses in the high school — the strongest published academic ceiling in the province. It runs a Model United Nations programme, a golf academy with its own short-game facility, and a community-service strand. CRICS teaches an American curriculum adapted to an international context, with every subject in English except Thai language, and awards a 22-credit diploma on the Carnegie system; its own guidance is that students preparing for a US university should take extra maths, science, US history and economics on top. One Hope teaches a Common Core-based programme in Mae Sai with an average class of twelve, and is still assembling the years above Grade 8.

On religion, be clear-eyed. Our own guide previously described CRIS as the secular alternative to CRICS. That was wrong: CRIS runs a weekly chapel which it describes as focusing on character development from a Christ-centred perspective, bringing discussion back to the teachings of Jesus. CRICS is more explicit again — Bible classes, weekly chapel, a statement of faith, and a required half-credit religious studies course in every year of enrolment as a condition of graduating — while stating in its own FAQ that it does not discriminate by religion and that students of any religion are welcome. Both of those things are true at once, and a non-Christian family should read them together rather than either alone. One Hope states that it intentionally applies a Christian worldview and that Christianity is practised at the school, alongside an inclusive mission welcoming all backgrounds. There is no fourth, secular option in the province.

One more fact CRICS publishes about itself that families should weigh honestly rather than dramatically: all of its foreign teachers are volunteers, recruited through mission and word-of-mouth networks. The school presents this as the reason its teachers are unusually invested, and it plainly relates to how the fee stays flat across every grade. It also means the staffing model is different from a commercially-staffed school, so ask about teacher tenure and year-on-year continuity in your child’s division.

What tuition costs, and why there are no numbers on this page

Chiang Rai is materially cheaper than Bangkok, Phuket or Chiang Mai for international schooling — that much is safe to say and it is one of the real reasons families come north. What we will not do is publish a per-school fee table. Schedules change every year, and the figures circulating in third-party directories disagree with each other: for the same school and the same academic year, two independent international-school directories currently quote ranges tens of thousands of baht apart, and neither figure comes from the school. A number that is wrong by that margin is worse than no number, because a family budgets against it.

So: request the current schedule directly — CRIS publishes a tuition and fees page, so does CRICS, and One Hope will send its schedule on request. Ask each school the same four questions: what is billed on top of tuition (application, entrance or capital fees are separate at all three); what lunch, transport, uniform and activities add; whether the fee rises by year group or stays flat; and what sibling discounts or financial aid exist. CRICS in particular runs its own financial-aid and multi-child discount programmes and does not advertise them loudly.

Burning season is a schooling question here

From roughly February to April, agricultural burning across the upper Mekong region pushes Chiang Rai’s air quality to among the worst readings in the country — regularly worse than Chiang Mai, which gets the headlines. If you are moving with children, this belongs in the school conversation, not the weather conversation.

CRIS hosts a public IQAir AirVisual station and links to its live readings from its own homepage, which is more transparency than most schools anywhere offer. Read it precisely, though: that is an outdoor measurement at the campus location. It tells you what the air is doing over Rimkok; it does not tell you what the air is doing inside a Grade 4 classroom. Neither CRICS nor One Hope publishes anything we could find on classroom filtration, indoor monitoring or a smoke-day policy — which is a statement about published information, not about what they do. On any visit between February and April, ask to stand inside a classroom with the doors shut and ask what the indoor reading is. Our Chiang Rai air-quality guide covers the season in full.

Where to live for Chiang Rai’s schools

There is no rail, no metro and no city-wide school bus network in Chiang Rai, so proximity is the whole game. Three practical bases in the city, and a fourth that is a different life entirely:

Admissions & relocation tips

With two realistic city options, start conversations six to twelve months ahead of the intake you want, and earlier again for CRIS boarding places. Expect an assessment or placement check, recent school reports and a family interview at all three schools. If your child is not a native English speaker, expect a language assessment specifically — CRICS requires an ELL assessment before admission and CRIS runs an ELD programme for students who need it. Gather transcripts, immunisation records and references before you leave your home country, and confirm whether an employer relocation package covers tuition and the one-time entrance or capital fee.

One Hope is the outlier on process and worth knowing about even if you are not moving to Mae Sai: it reports no waiting list, a 15 September registration deadline, and that students may join after the academic year has begun. For a mobile family on a DTV or similar long-stay route, that flexibility is unusual in Thailand and genuinely valuable — the constraint is the Grade 8 ceiling, not the door. Families on a tighter budget or planning a shorter stay should also look at local Thai and bilingual private schools, and should weigh Chiang Mai seriously if curriculum variety, a secular option or a larger peer group matters more than Chiang Rai’s lower cost of living and quieter pace.

Before you plan a move around a school you found online

Chiang Rai is a small field, and small fields get described badly. AI-generated school listicles now routinely invent schools that do not exist, garble the names of ones that do, and place real campuses in the wrong district — we have found all three across Thai cities, including here. The two independent international-school censuses we checked for this guide agree on exactly three schools in the province, and both name the Mae Sai school One Hope International School. Before you plan anything around a school you found in a search summary, apply three tests: does it have its own website on its own domain; can you find a specific address on a map; and does the telephone number answer. If any of those fails, treat the school as unverified until you have spoken to a human being at it.
