A very warm welcome to the International School of Luxembourg.

Greetings, and welcome to the International School of Luxembourg. We are pleased that you are visiting our website. In the pages that follow, you will undoubtedly discover that ISL has a well-deserved reputation for outstanding student achievement, robust programming, an extremely talented and dedicated staff, and a caring, international community committed to intercultural understanding and global engagement.

Our mission is to ensure that everyone in our community becomes inspired, resilient and passionate about achieving what matters, anywhere in the world. This mission drives all that we do here. The resulting focus on a rigorous, holistic, inquiry-based international education that respects individual and cultural differences while promoting individual agency is a big reason why our students love coming to school every day. With over 50 nationalities within the student body and over 20 nationalities on staff, daily life at ISL is international, dynamic and engaging.

In these extraordinary times, we are also paying close attention to the well-being of not just our students, but all our community members. As we navigate the challenges of COVID 19, we aim to remain agile and keenly responsive to the needs of our community, as health and safety are always our highest priority. To this end, we partner closely with our parents, our tireless Board of Governors, and with local and global organizations.

Whether you are a prospective student, parent or educator, we hope that by browsing this website, you will get a good sense of why ISL is the premier English-language international school in Luxembourg. If you would like to visit in person, we would be delighted to welcome you to campus to show you around so you can see for yourself why ISL is such a special place.
