Admissions

Admissions
1. Explore: Learn about ISBasel's personalised approach to education and schedule an individual consultation in person or online to understand how ISBasel can support your child. The school outlines three levels—Junior School (ages 3–11), Middle School (ages 11–14), and Senior School (ages 14–18)—which you can discuss during this consult. This initial exploration helps families determine fit before moving to the next steps.

2. Visit: ISBasel's doors are open year‑round. Schedule a visit or call, and you will be welcomed for an individual tour at your convenience. During the visit you can explore the school in depth and meet key staff members. This visit is designed to give you a first‑hand sense of the school environment and community.

3. Register & Apply: The Admissions Team is here to assist you every step of the way. ISBasel enrols students throughout the year, dependent on space and fulfillment of entry requirements. They provide personalised support and guidance on documentation, application forms, and admission criteria. You can ask questions about the process and receive help with next steps as you prepare your dossier.

Additional assessment outcomes may be required; the level of English proficiency and any student support needs will be reviewed.
