The International School of Lausanne

The International School of Lausanne (ISL) was founded in 1962 as a non-profit coeducational day school to serve the expatriate and local communities in the city of Lausanne. Facing the French-speaking Alps, ISL is highly regarded as the leading school in the region for its record of excellence in teaching and learning. 

Mission and Aims

With a focus on active learning, open inquiry, critical and creative thinking, and independence of thought, ISL aims to provide opportunities for every student to be successful, while encouraging personal and collective responsibility. Our results are excellent but a good school is so much more than that. We pride ourselves on the nature of relationships and work hard to ensure that each student feels both valued as an individual and connected to the diverse and exciting social and cultural environment of our international student body.


ISL is an International Baccalaureate World School, offering all three IB programmes: The Primary Years Programme, the Middle Years Programme, and the Diploma Programme.  In the High School, students follow the last two years of the IB Middle Years Programme in Years 10 and 11 (Grade 9 and 10) and the two-year pre-university IB Diploma Programme in Years 12 and 13 (Grades 11 and 12). Approximately 98 percent of ISL students will following the full IB Diploma Programme, with one or two students in each year taking only selected IB Diploma courses.

Student Body

The student body at the International School of Lausanne consists of more than 880 students from the ages of three to 18. There are more than 72 nationalities represented within the student body, the largest groups being the USA, the UK, Switzerland and France. 


Since 1981, ISL has been accredited by the European Council of International Schools and the New England Association of Schools and Colleges. The date of the most recent accreditation for both Primary and Secondary Schools was October 2016. 


We place a great emphasis on activities beyond the classroom.  ISL encourages students to engage in a diverse range of activities to enhance their academic curriculum, equipping them with skills that will prepare them for the challenges of the 21st century.  ISL clubs and teams include: basketball, football, uni-hockey, volleyball, tennis, athletics, dance, gymnastics, swimming, skiing, netball, rugby and badminton. 

Students also participate in a number of activities and clubs in the local community. There are also a range of creative activities to participate in, including, but not limited to, Model United Nations, French and English theatre productions, Student Council, forensics and debate, school newspaper, yearbook, literary magazine, chess club, art classes, concert band, stage band and choir. 


Genuine respect, openness and warmth towards one another characterises the ISL community. We believe that only by forging strong relationships between students, parents and the school can children realize their full potential.

With a diverse mixture of nationalities, ISL takes full advantage of the rich cultural nature present in its community. Visible both in the classroom and through diverse community events, the individual identities of the students are recognized and celebrated.

A thriving Parent Teacher Association (PTA) is instrumental in supporting new and existing families through a range of activities including coffee mornings, cultural events, parents’ evenings and children’s activities. From their children’s enrolment to their very last day and beyond, families are welcomed and encouraged to play their part in making the community a warm, supportive and dynamic place to be.
