History	History ISZL has a deeply rooted history in the canton of Zug in Central Switzerland, where our story began long before we embraced the name ISZL. For more than 60 years, ISZL has grown from a small tutoring group for 14 American children of Willy's employees, known as Willy's School, to an expansive multicampus community serving around 1,200 students from 60 countries. What began as Willy's School was renamed the Zug Anglo-American School in 1964, and the campus relocated through the 1960s to accommodate growth. In 2008, the merger of the International School of Zug, the International School of Luzern, and the Riverside School formed the ISZL we know today, followed by expansion such as Chalet Bergheim and the mission 'Respect, Motivate, Achieve'. Plans for a new Middle School campus next to the High School in Hünenberg are planned for opening in 2028.	History Tandem IMS was set up by multilingual education specialists to advance primary education through multilingualism. It began with six children at the Uetikon site and grew to over 300 children from about 30 nationalities, with campuses in Erlenbach, Küsnacht, Zollikon and Zurich. Sonya Maechler-Dent founded the first Tandem IMS school in Uetikon am See and led expansion; the name Tandem International Multilingual School was adopted in 2010 with the motto 'Discover the world through languages'. In 2024 Tandem IMS celebrated 20 years of multilingual education, and in 2025 opened the Küsnacht campus hosting the Gymnasium and primary grades 5 and 6.
Community	Community ISZL has strong ties with the wider Swiss community. Orientation Day is held on both the Zug and Riverside campuses to welcome new families, and the PA provides Community Representatives to connect families with others who share cultural backgrounds. The annual ISZL Community events include International Day, Community Festival, the Winter Market, Welcome Fair, Trunk or Treat, Quiz Night, and Wine & Cheese tasting. The PA's Neighbourhood Networks help connect families with local services, carers and clubs.	Community Tandem IMS operates across four campuses: Erlenbach, Küsnacht, Zollikon and Zurich, serving Early Years through Gymnasium. The school offers After School Clubs and Holiday Camps as part of its community life. The multilingual environment includes engagement in English as the administrative language and classroom use of multiple languages, with 57% of students communicating in three or more languages and students from around 30 nationalities. The community emphasizes welcoming newcomers and fostering a family ethos across campuses.
Parent teacher association	Parent teacher association ISZL's Parents' Association (PA) is the active volunteer body behind the ISZL community, with over 300 volunteers who help organise events and welcome new families. It supports school initiatives and offers social and cultural activities, informal coffee mornings, and practical advice to families settling in. Class and Grade Representatives act as a bridge between parents and the school, with class representatives in Primary and grade representatives in Middle and High School. The PA connects families through Neighbourhood Networks to share local tips and arrange carpooling. The PA also leads and supports a range of clubs and events, including the annual International Day.	Parent teacher association The Tandem IMS PTA is an active link between teachers and parents to support school life in a wide variety of ways. It meets regularly and organizes volunteer groups to enhance school experiences, seeking input from a broad range of viewpoints. Its main objective is to partner with Tandem IMS to make a positive difference for children, strengthen the home–school link, and promote the Tandem IMS ethos. It organises events, projects and celebrations and welcomes newcomers to the Tandem IMS family. PTA funds are invested in extras to enrich learning and life for children, parents and staff.
