It's best to ask — circumstances can change at any time.

Chiang Mai International School (CMIS) started in 1954 as a small school for children of missionaries in northern Thailand. It now offers classes from preschool through Grade 12 and follows a U.S.-based curriculum taught in English. The school is accredited by the Western Association of Schools and Colleges (WASC) and approved by the Thai Ministry of Education. High school students can take Advanced Placement (AP) courses that help prepare them for university. Students come from many different countries, and the school does not require any specific religious background. The school is located in Chiang Mai and has a range of facilities to support learning and activities. These include a swimming pool, sports fields, covered play and sports areas, a theatre, music and dance rooms, and classrooms for art and languages. Students can join activities outside of regular classes, such as sports or music. The school keeps its class sizes relatively small, and students of different ages and backgrounds learn together in a shared space.

Chiang Mai International School teaches Advanced Placement (AP), American Curriculum for students aged 3 to 17.
Chiang Mai International delivers an American standards-based curriculum across Preschool to Grade 12, using Common Core (ELA & Math), NGSS (Science), and C3 (Social Studies) frameworks. Preschool follows the inquiry-driven Creative Curriculum focused on play-based development and foundational literacy, numeracy, art, Thai language, music, PE, and library time. Elementary (K–5) builds on those standards with specialist-taught subjects including computers, art, music, PE, and Thai language and culture. In Middle School (Grades 6–8), students take core subjects plus electives in wellness, drama, music, art, computers, and languages, supported by strong social-emotional learning and laptop integration. High School (Grades 9–12) continues core instruction alongside a broad elective catalogue (PE, art, tech, drama, languages), while offering Advanced Placement (AP) courses and the AP Capstone Diploma (AP Seminar & Research). All divisions also offer Thai language, culture, and history at Novice, Intermediate, and Advanced levels, and provide learning support via the Student Success Department for students with identified needs.
The school does not publicly display detailed information about Social and Emotional Learning (SEL) on its official website. However, CMIS lists a wellness coach, counselors, and a spiritual advisor as part of its Student Support Team. Homeroom teachers are also positioned to provide day-to-day guidance and care. These roles suggest that SEL is embedded through staff responsibilities, but no specific SEL programmes, frameworks, or classroom practices are described.
The school does not publicly display detailed information about Special Educational Needs (SEN) provision on its official website. CMIS is not a specialist SEN institution but lists a Special Teaching Assistant among its staff, indicating some capacity for support.
The school does not publicly display detailed information about its EAL provision on its official website. CMIS does list an EAL Coordinator among its faculty, which implies that support is offered for students learning English as an additional language.
The school does not publicly display detailed information about mental wellbeing programmes on its official website. CMIS includes counselors and a wellness coach on its staff, suggesting some support for student mental health.
The school does not publicly display detailed information about its safeguarding policies or procedures on its official website. It does note that all staff are required to pass background and police checks as part of the hiring process, which is a basic safeguarding measure.
1. Book an Open House or campus visit.
CMIS offers group visits where up to three families can tour the campus by appointment. These visits are not testing days but give you a chance to see facilities and ask questions before applying.
2. Submit the online application form and documents.
Parents complete the digital application and upload required items like student passport, school reports (last 2 years), a teacher recommendation, birth certificate, immunization records, and any learning assessments or support documentation if relevant.
3. Admissions review and eligibility check.
The Admissions Team reviews your child’s academic performance, age eligibility, English language level, and any learning support needs. They will contact you to clarify missing details or proceed with the next step.
4. Pay the application fee and confirm testing.
Once the Admissions Team has reviewed the application and determined that the student may be a fit, they will reach out to arrange entrance testing. The official application form states that a non‑refundable fee is due at this stage, though this is not stated on the admissions webpage. Testing typically includes English and math assessments and may vary by grade level.
5. Attend entrance assessments.
The student completes their evaluation either on campus or remotely (if overseas). This helps the school assess academic fit and determine if English as an Additional Language (EAL) or other support services may be needed.
6. Receive an admission decision.
After reviewing all results and documentation, the school provides an official response. If accepted, your child is offered a seat, and you’ll receive an offer letter with next steps for enrollment.
7. Complete the enrollment process.
To finalize the place, you must submit required forms, pay the enrollment fee, and confirm your child’s start date. CMIS will then coordinate with your family on orientation and the start of classes.
CMIS offers one formal scholarship and one discounted tuition category, both outlined on the school website and related documentation:
1. Outstanding Senior Scholarship Award
A merit-based scholarship sponsored by the CMIS Parent Teacher Group (PTG), offering a cash award of 35,000 baht. It is awarded annually to a graduating senior who demonstrates academic achievement, leadership, and community involvement.
Eligibility criteria include:
Attending CMIS for more than one academic year (including the current year)
Being eligible to graduate in good standing
Submitting an application and a written essay
Selection is based on:
GPA at CMIS
Demonstrated leadership and service at school and in the broader community
Quality and persuasiveness of the essay
The recipient is chosen by a committee of CMIS faculty, administration, PTG representatives, and one parent not connected to the senior class.
2. Missionary Tuition Discount
CMIS offers a reduced tuition rate to families engaged in full-time Christian missionary work. Eligibility must be verified with the school. This is not a merit scholarship but a discounted fee structure applied to qualifying applicants.
CMIS does not operate a formal numbered waitlist or rolling admissions pool. Instead, when a grade level reaches capacity, the school uses a priority-based consideration system.
The official CMIS Priority Categories are:
Christian missionary families
CMIS staff children
Diplomatic or consular families
Former CMIS families returning from abroad
NGO or non-profit organization families
Siblings of current CMIS students
All other applicants (considered on a space-available basis)
CMIS states that it "reserves spaces for qualified priority applicants," meaning that space may still be held for someone in a higher category even if others are already waiting.
