IB International School in Lausanne, Switzerland

ISL is an International Baccalaureate (IB) World School

We offer the Primary Years, Middle Years, and Diploma Programmes for children aged 3-18. We are known for our academic excellence and rigorous teaching which encourage children to achieve the highest standards. But good grades aren’t enough to succeed in a complex, changing world. That’s why we develop creative and independent children who can solve problems and adapt.

An ISL education

The world is increasingly interconnected. Many of today’s challenges require clear thinking, dialogue, and cooperation. ISL prepares children for the complexities and uncertainties of our multicultural, interdependent world so that they can contribute productively.

An ISL education provides young people with:

a rigorous intellectual base so they can think critically
opportunities for innovation and independent problem-solving
the ability to effectively cooperate across cultural boundaries
a genuine sense of caring for the well-being of all community members
confidence and the courage to be themselves

“We think there is no limit to a child’s potential and we help every student explore theirs, so they have the best possible chance of leading a successful, fulfilling life. ”
Frazer Cairns, School Director

Service learning at ISL

The International School of Lausanne is committed to developing students who will make a meaningful contribution to the world

At ISL we believe service learning forms an essential component of a holistic education, providing the opportunity for students to make links between their curriculum studies and the wider world. It is an opportunity for them to reflect on their social responsibilities and prepare them to take an active and responsible role in a multicultural world.
