About ISB

ISB is more than a school.

Lee Fertig, International School of Brussels Director

It is more than a record of outstanding achievements in academics, arts, and athletics. It is more than a place where traditions are valued and innovation is embraced. It is an extraordinary learning community that brings together over 1,350 students from more than 75 countries; a community that looks back on a long and distinguished legacy, but also one that embraces the future with openness and optimism.

Whether you are returning here as a former student, choosing the right school for your children in Brussels, or interested in teaching at ISB, we hope our site provides you with a sense of life and learning at ISB.

Kind regards

Lee Fertig
ISB Director
