Welcome to the International School of Luxembourg

A thriving Preschool - Grade 12 international school
for children aged 3 - 18 years

We provide an outstanding education and inspire our students to engage in both academic and enriching co-curricular programmes. Our students enjoy school and set high expectations for themselves. The community is continually rewarded by their achievements.


ISL Parents in ISL Upper School Cafeteria, learn about the theory of knowledge (TOK) in a special breakfast dedicated to the subject.

Theory of Knowledge (ToK) is essentially a deep-critical-thinking course, which invites Upper School students to consider the way knowledge is produced, its relationships and values, how we communicate our beliefs and opinions, and why knowledge develops over time. The five areas of knowledge help to discover this: the Arts, History, Human Science, Mathematics, and Natural Sciences. In ToK classes, we investigate how the nature of knowledge differs in these areas. With the help of concepts such as perspective, objectivity, truth, evidence, and certainty, the students analyse real-life situations in and out of the classrooms.

“Stumbling stones” are brass plates, which remember the life and death of victims of Nazi persecution. What a special moment when the students of the German A class were allowed to hold a “stumbling stone” in their hands, which remembered the deportation and the death of Bernard Nussbaum, a 10 year old Jewish boy from Luxemburg.

As I retire after twenty-six years at ISL, it has been a privilege and a pleasure to be a part of its growth.
