Set against the stunning backdrop of the Swiss Alps, the International School of Sion (IS Sion) offers more than an education, it offers a place to grow, to connect, and to belong. As a coeducational day and boarding school for students aged 14 to 18, IS Sion is home to a vibrant international community where academic ambition is balanced with care for the individual, respect for diversity, and a commitment to shared human values.

IS Sion is proud to be a Cambridge International School, offering a globally respected curriculum that combines academic rigor with the flexibility to meet each student’s interests and aspirations. Our four to five-year academic journey begins with the Foundation Programme in Grade 9, leading to the prestigious Cambridge IGCSEs and  A Levels. Throughout, students are challenged to think critically, act ethically, and take ownership of their learning, supported by teachers who know them personally and believe in their potential.

At the heart of IS Sion is a culture of respect, kindness, and integrity. Our small community fosters strong relationships between students, teachers, and families, creating an atmosphere where everyone feels seen, heard, and valued. The on-campus boarding house offers more than accommodation; it provides a family-style home where young people from around the world learn to live together, share experiences, and build lifelong friendships.

Beyond academics, IS Sion places great emphasis on personal development, wellbeing, and community engagement. Students are encouraged to explore their talents and interests through sports, the arts, leadership opportunities, and service projects, fostering empathy, creativity, and a sense of purpose. The school’s unique alpine setting offers daily opportunities to connect with nature, promoting balance, resilience, and environmental stewardship.

IS Sion prepares students not only for academic success and university entry but for life. Our graduates leave with strong qualifications, but also with open minds, compassionate hearts, and the confidence to contribute meaningfully to an interconnected world.
