ISZL Community

Founded in 1961, the International School of Zug and Luzern (ISZL) is an award-winning, non-profit International Baccalaureate® (IB) World School in Central Switzerland. We provide an exceptional education for students aged 3 to 18 — preparing them for university and life beyond.

At ISZL, learning goes beyond the classroom. Our students explore the Swiss outdoors, lead service projects, perform on stage, and compete in sports. United by the phrase “We are all ISZL,” our community lives by the values of courage, joy, curiosity, belonging, and service.
