Admissions

Admissions
1. Parents can contact the school directly by phone or email to express interest in admission. The school provides application materials such as a comparison chart and a downloadable application form. Families are encouraged to begin this process at least two months before the September intake.

2. Completed applications must be submitted to the school office along with the required documents. The school accepts applications throughout the year, particularly to accommodate families relocating to Koh Samui outside the main intake period.

3. Where possible, families are invited to visit the campus. This allows parents to tour facilities, ask questions, and meet with staff to better understand the curriculum and teaching approach. This step is especially helpful for families new to international education in Thailand.
