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 have close to 1000 students.
