Discover What Sets ISZL Apart

ISZL is an award-winning co-educational day school in Central Switzerland, founded in 1961. As an International Baccalaureate® world school for students aged 3 to 18, we offer a comprehensive and rigorous academic programme that connects students to the world around them. Our vibrant, multicultural and caring community fosters a deep sense of well-being.

During our time at ISZL we were greatly appreciative of the open door policy, nurturing environment and friendly professional communication at the Middle School. Our boys have learned invaluable experiences, gained lifelong skills and made wonderful friends.
