International School of Zug and Luzern

The International School of Zug (ISOZ) was founded 1961 in Zug. With just fourteen students, ISOZ provided an English speaking, comprehensive and stimulating primary education for expatriate families in the region. The school's excellent climate for fostering student development was responsible for its success; the school eventually grew to over 700 students. ISOZ provided the forerunner of the Primary Years Programme (PYP) of the International Baccalaureate (IB) since its inception in the early 1990s and was recognised as a leading IB World School in the delivery of the programme. The campus is still set in the tranquil and beautiful countryside on the outskirts of the small town of Baar, halfway between Luzern and Zurich. The Luzern Campus was founded in 2006 as a sister school to the long established International School of Zug. Its aim was to provide an international English speaking education for the large and thriving expatriate community of central Switzerland. Classes for students aged between three and twelve years (Early Years 1 to Grade 5) were located in three historic buildings on the spacious campus. The campus was situated in Kastanienbaum on the outskirts of the town of Horw. The main school building remained the Villa Krämerstein, set on its own grounds at the edge of Lake Luzern. The Luzern Campus closed in June 2016, with the remaining students transferring to the Zug Campus. The Riverside School was founded in 1990 as a university preparatory high school and in 2001 became the first school in Switzerland authorised to offer the Middle Years Programme (MYP) of the International Baccalaureate (IB). It has offered the College Board's Advanced Placement (AP) programme since its inception. Outstanding results have led to an exceptional track record of university placements worldwide. In 2007, Riverside was authorised to offer the Diploma Programme of the International Baccalaureate (IB). With the merger of these schools on August 1, 2008, the International School of Zug and Luzern (ISZL) serves the needs of around 1,300 students from more than 50 different nationalities on two outstanding campuses.
