Is CMIS an American or IB school?

Both. CMIS follows a U.S. standards-based curriculum throughout the school and additionally offers the IB Diploma Programme as the Grade 11–12 pathway, so families can choose a U.S. high-school diploma, the IB Diploma or both.

Yes. CMIS is accredited by the Western Association of Schools and Colleges (WASC) and is licensed by the Thai Ministry of Education as an international school.

How central is the campus?

Very. CMIS is in the Wat Ket area on the east bank of the Ping River, a short drive from the Old City, Nimman and the night-bazaar area, which makes it a popular choice for downtown-based expat families.

Does CMIS require an entrance test?

Yes. Applicants complete English and maths assessments appropriate to their grade level and attend an interview; recent school reports are also required.

What is the religious character of the school?

CMIS was founded by missionaries and retains a Christian ethos with chapel and Bible classes, but it enrolls students of all faiths and backgrounds.
