Admissions Welcome

Choosing a school is often one of the most important decisions you are faced with as a family when moving countries or seeking a new educational environment. We strive to ease this decision for applicant families by offering clear, transparent, personalized guidance about ISL and its admissions process.


We look forward to being in contact with you throughout the application process and hope to welcome you to ISL's warm and supportive community. Submission of applications is open for the 2023-2024 and the 2024-2025 school years.

The application season for the 2024-25 school year is open and we invite you to visit the ISL Application Timeline for more information. Please be advised that currently a waiting pool is expected for grade 10 and other grade levels may follow. You are always to contact us directly for latest update on expected space availability.

Should you wish to apply for the 2023-24 school year, please do not hesitate to contact us for latest information on space availability. Some grade-levels in both Lower and Upper School are currently at full capacity or may reach full capacity soon. We look forward to hearing of your interest in applying for the 2023-24 school year as soon as possible, so communication with your family can begin and we can provide you with the latest update on enrolment availability.
