Overview

Chiang Rai International Christian School has operated since 1998, twelve years before Chiang Rai International School (CRIS) opened in 2010, which makes it the province’s longest-running international school. It describes itself as a family learning community and delivers an American curriculum, adapted to an international context, from Kindergarten through Grade 12. Classes are capped at an average of fifteen at every grade level across a roll of roughly 150 students, and tuition is flat by year rather than rising with age — which makes multi-year budgeting unusually simple.

BAANLYY is not affiliated with CRICS and takes no paid placement in this guide. We publish no per-school fee figures anywhere on this site, because schedules change annually and the copies circulating in third-party directories disagree with one another by wide margins — CRICS publishes its own tuition and fees page, which is the only figure worth budgeting against. Ask separately about the school’s financial-aid and multi-child discount programmes; it does not advertise them loudly.

Accreditation and what students leave with

CRICS states in its own FAQ that it is fully accredited by the Western Association of Schools and Colleges (WASC), the Association of Christian Schools International (ACSI) and Thailand’s Office for National Education Standards and Quality Assessment (ONESQA). That triple is the practical answer to the question relocating families most often forget to ask: whether a transcript from this school will be read as legitimate by a university admissions office in another country.

Graduation runs on the Carnegie credit allocation system and requires 22 credits: four in Language Arts; three each in Science, Maths and Social Studies (including two credits of World History and Geography and half a credit of Comparative Government); two in PE and Health; two in a foreign language; half a credit of Computer Science; and 4.5 in electives. Students preparing for a US university are advised by the school to add a further credit of Maths, a further credit of Science, a credit of US History and half a credit of Economics on top of the minimum. The school also states that its graduates are able to speak, read and write English fluently and are ready to attend an overseas college or university.

Curriculum, faith and community

CRICS teaches across three divisions — Elementary (Kindergarten to Grade 6), Middle School (Grades 7–8) and High School (Grades 9–12) — with every subject taught in English except Thai language. Alongside the academic programme it runs athletics, fine arts, a student council, scouts, a Model United Nations elective, its own library and a set of support services. Students who are not native English speakers sit an ELL assessment before admission to confirm their English is sufficient for classroom work.

On faith, the school is direct and so are we. CRICS publishes a statement of faith, runs weekly chapel and Bible study, and requires a half-credit religious studies course in every year of enrolment in order to graduate. It also states, in the same FAQ, that it does not discriminate by religion and that students of any religion are welcome. Both of those things are true simultaneously, and a non-Christian family should read them together rather than seizing on either alone: the door is genuinely open, and the curriculum genuinely has a required religious component. Note too that this is a difference of degree rather than of kind within Chiang Rai — CRIS also runs a weekly Christ-centred chapel, and there is no secular international school anywhere in the province.

One further fact the school publishes about itself, worth weighing honestly rather than dramatically: all of its foreign teachers are volunteers, recruited through word of mouth, mission and recruiting organisations and online postings. CRICS presents this as the reason its teachers are unusually invested in their students, and it plainly relates to how the fee stays flat across every grade. It also means the staffing model differs from a commercially-staffed school, so ask about teacher tenure and year-on-year continuity in the division your child would join.

Who this school suits — and who it can’t take

CRICS suits families who want small classes, an accredited American pathway to a US diploma, a long institutional track record and a close-knit community, and who are comfortable with — or actively want — an explicitly Christian school. It is the province’s value option in the honest sense: the same accredited destination as CRIS, without AP, without boarding, and without a preschool.

The hard constraint is the bottom of the age range. CRICS starts at Kindergarten, age 5. A family arriving with a three- or four-year-old cannot enrol there at all and needs a plan for those two years — CRIS in Rimkok takes children from age 3, as does One Hope in Mae Sai, and local Thai nurseries are the other route. If your child needs Advanced Placement for a North American university application, that is only available at CRIS.

Location, the school run & burning season

The campus is in Ban Du, an outlying pocket of Mueang Chiang Rai district a short drive from the city centre — a lower-rent area that trades some walkability for space and value, and covered in full in our Chiang Rai areas guide. Chiang Rai has no rail or metro of any kind and no city-wide school bus network, so CRICS families drive or arrange a private transfer. Confirm what transport, if any, the school currently operates before you sign a lease on the strength of it.

We could find nothing published by CRICS on classroom air filtration, indoor monitoring or a smoke-day policy for Chiang Rai’s February-to-April burning season, when the province’s air is regularly among the worst in Thailand. That is a statement about the available information rather than about what the school does — many schools filter without advertising it. Ask on any visit between February and April, and read our Chiang Rai air-quality guide before choosing a start date.

FAQ

How long has CRICS been operating?

Since 1998, which makes it Chiang Rai's longest-running international school — twelve years older than Chiang Rai International School (CRIS), which opened in 2010.

What curriculum does CRICS follow, and what do students graduate with?

An American curriculum adapted to an international context, from Kindergarten through Grade 12 (Elementary K–6, Middle School 7–8, High School 9–12), with all subjects taught in English except Thai language. Graduation runs on the Carnegie credit system and requires 22 credits: 4 in Language Arts, 3 each in Science, Maths and Social Studies, 2 in PE and Health, 2 in a foreign language, half a credit in Computer Science and 4.5 in electives. The school's own guidance is that students preparing for a US university should take an additional credit each of Maths and Science, plus US History and half a credit of Economics on top of the minimum.

Is CRICS accredited?

Yes, and it is explicit about it: the school states it is fully accredited by the Western Association of Schools and Colleges (WASC), the Association of Christian Schools International (ACSI) and Thailand's Office for National Education Standards and Quality Assessment (ONESQA). That combination is what makes a CRICS transcript legible to a university admissions office abroad.

Does CRICS accept students who are not Christian?

The school states plainly in its own FAQ that it does not discriminate by religion and that students of any religion are welcome. Read that alongside a second fact from the school's own graduation requirements: every student takes a half-credit religious studies course in each year of enrolment as a condition of graduating, and students study the Bible and attend chapel. Both are true. A non-Christian family should weigh them together rather than either alone — the door is open, and the curriculum has a required religious component.

Does CRICS have a preschool or nursery?

No. CRICS begins at Kindergarten, age 5. If you are arriving with a three- or four-year-old, the province's early-years options are CRIS in Rimkok, One Hope in Mae Sai, or a local Thai nursery — CRICS is not available to you until your child turns five.

Who teaches at CRICS?

The school states in its own FAQ that all of its foreign teachers are volunteers, recruited through word of mouth, mission and recruiting organisations, and online postings. The school presents this as the reason its teachers are unusually invested in their students, and it plainly relates to how tuition stays flat across every grade level. It also means the staffing model differs from a commercially-staffed school, so it is fair and sensible to ask about teacher tenure and year-on-year continuity in your child's division.

Where is CRICS located?

At 331 Moo 14, Ban Du (Baan Duu), in Chiang Rai's Mueang district — a short drive from the city centre, and also covered as a lower-rent outlying residential pocket in BAANLYY's Chiang Rai areas guide.
