We are a non-profit, independent, International Baccalaureate (IB) World School. Since 1962, we have grown to almost 1000 students, aged 3 to 18 years, who come from more than 60 nations. We believe in strong values, the courage to think independently, and cooperation across cultural boundaries–ideas that form the heart of a progressive approach to learning.

Students at the gym in the eighties


The English School of Lausanne opened with seven students in the rehearsal rooms of the Municipal Theatre in 1962. The following year the school was renamed The Commonwealth-American School. It grew within five years to over 100 students from nine different countries. The school was finally renamed the International School of Lausanne (ISL) in 1997. We now welcome close to 1000 students.
