Bangkok is one of the fastest-growing hubs for international education in Southeast Asia. Home to more than 200 international schools serving a broad spectrum of budgets, the city attracts expat families relocating for regional headquarters roles, manufacturing, NGO work and remote-friendly lifestyles.
Getting admissions right in Bangkok requires understanding a few specificities: a highly stratified market, the importance of the ED (Non-Immigrant) visa, and admission deadlines that start earlier than most families expect. This 2026 guide walks you through every step.
How Bangkok private school admissions work
Bangkok's international schools operate on rolling admissions with two primary intake points: August (Northern Hemisphere calendar, most common) and January (Southern Hemisphere, used by Australian-style schools). A smaller group of schools runs three-term years with April and September starts.
Unlike Western markets, a considerable share of Bangkok's international schools maintain year-round enrolment and can accommodate arrivals mid-term, especially for early years and Primary. Sixth Form and IGCSE entry points are more competitive and fill earlier.

Top private international schools in Bangkok
KIS International School Reignwood Park
KIS International School Reignwood Park offers the full IB continuum in a purpose-built campus on the northern edge of Bangkok. The school combines strong academics with a focus on outdoor learning thanks to its sprawling natural campus, and attracts families who want an international curriculum with green space not easily available in central Bangkok.
Glory Singapore International School
Glory Singapore International School delivers the Singapore curriculum adapted for Bangkok, known for its rigorous mathematics and Mandarin programmes. It is a popular choice for families from the Chinese-speaking world and for those who want their children to follow the Singapore Primary School Leaving Examination (PSLE) pathway.
Student visas (ED visa): the critical step
All foreign students aged 7 and above enrolling at a Thai international school need an ED (Non-Immigrant) visa. The school issues an admission letter and a Certificate of Guarantee, which are then used to apply at a Thai embassy abroad or converted inside Thailand from a tourist visa. Key points to plan around:
- Lead time of 4 to 8 weeks for the certificate
- Annual renewal inside Thailand (90-day reporting for longer stays)
- One accompanying parent can apply for the Non-Immigrant O visa based on the child's ED visa
- Schools help coordinate but do not sponsor the visa — the family is responsible
Assessments and interviews
For Kindergarten and Year 1 applicants, admissions are based on a 45 to 60 minute observation session. From Year 2 onwards, expect English language and mathematics assessments using standardised instruments like MAP, CAT4, WIDA or proprietary school tests. Many Bangkok schools also conduct a student interview from Year 4 upwards and a parent interview at all levels.
Students with limited English have access to EAL (English as an Additional Language) programmes in most Bangkok schools. Capacity is limited per year group, so apply early if EAL support is needed.
School fees and additional costs
Bangkok offers one of the widest fee ranges in Asia. Typical 2026 tuition (mid-tier to premium):
- Pre-school (ages 3 to 5): THB 280,000 to THB 720,000 per year
- Primary (Years 1 to 6): THB 430,000 to THB 900,000
- Secondary (Years 7 to 11): THB 560,000 to THB 1,050,000
- IB Diploma or A Levels (Years 12 to 13): THB 650,000 to THB 1,200,000
Expect additional one-off fees of THB 100,000 to THB 350,000 for application, registration, capital fees and deposits. Recurring extras include uniforms, lunches, school bus and trips, typically adding 8 to 15 percent of tuition.
Practical tips for expat families
- Apply to two to three schools simultaneously. Rolling admissions and waitlists make parallel applications the norm.
- Plan around traffic. Bangkok commutes are brutal between 7 and 9 a.m.; live within the school bus coverage area.
- Ask about scholarships. Many schools offer merit scholarships at Year 7 and Year 12 entry worth up to 50 percent of tuition.
- Check for corporate rates. If your employer has a recruitment partnership with a specific school, fee reductions and priority admissions may apply.
- Do not skip the entrance exam. Even if admissions look guaranteed, the assessment determines year-group placement and EAL support.
