How admissions usually works at Bangkok international schools
- The school year at most Thailand international schools starts in August or September; some schools also run January or April intakes.
- Applications for an August start commonly open the preceding autumn (September–November), and popular year groups can fill months ahead — applying early rarely hurts.
- Mid-year entry is often possible where a place exists; schools usually assess the child (English and maths are typical) and ask for recent reports from the previous school.
- Expect one-off charges on top of tuition — an application or assessment fee, then a registration / enrolment fee and often a refundable deposit once a place is offered. Each school's fees page here shows its published wording in full.
- Documents are usually some combination of the child's passport or birth certificate, parents' ID, previous school reports and immunisation records.
