Discover the International School of Luxembourg
A thriving Early Years to Grade 12 international school for children aged 3 - 18 years
Early Years
Ages 3 - 5
In the Early Years at ISL we believe that every child has enormous potential and is a valued contributor both to their own learning and to their world.
Primary Years
Ages 6 - 11
In Grades 2 -5 in the Lower School, our students are engaged in learning that inspires them to want to investigate further, to understand more fully, to apply learning and to become enthusiastic and active participants in learning in all its forms.
Middle School
Ages 11 - 14
Students in the Middle School are making the transition from childhood to adolescence and are passing through a critical phase in their intellectual, emotional and physical development. Within the Upper School we have developed a middle years programme specifically to meet these needs.
High School
Ages 14 - 18
During the High School years students develop the motivation and self-reliance that they will need at college or university and beyond. To this end, we offer a challenging and stimulating curriculum. In Grades 11 & 12, most students follow the International Baccalaureate Diploma programme.
