International School of Sion

This school in Sion focuses on secondary students aged 14 to 18, offering Cambridge International qualifications including IGCSE and A Levels. The mountain location provides a distinct alternative to the urban Geneva and Zurich schools, and the school welcomes both day and boarding students. The curriculum emphasizes individual attention and preparation for UK and international universities.

Families with secondary-age children seeking a Cambridge education in a quieter, Alpine setting should consider this option. Day students from the Valais region mix with boarders from across Switzerland and abroad, creating a genuinely international community. The school suits families wanting UK-style education without relocating to Britain itself.
