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.

General guidance only — this is not SISB Thonburi / SISB Suvarnabhumi's policy. Always confirm dates, fees and requirements with the school.
