Which schools have the lowest fees?
Annual tuition across the schools listed here ranges THB 135K–THB 517.5K. Sort the comparison table by annual tuition to see the most affordable options first. Fees vary by grade level and whether boarding is offered.
Can my child enrol without speaking the local language?
Many international schools teach in English and accept students with limited local-language ability, often through EAL (English as an Additional Language) support. Entry requirements differ by school and grade — check each school's admissions page for its language policy and any assessment.
How is the school year and grade level counted?
International schools usually follow their home system's grade names (for example US grades, UK years or the IB programme structure), which may not map one-to-one to the local system. Each school listing shows the age range it serves so you can match your child's stage.
When can students transfer in?
Most schools accept applications year-round and admit mid-year subject to availability, though the main intake aligns with the start of the academic year. Places in popular grades can be waitlisted — apply early and confirm transfer timing with the school directly.
