Luxembourg’s public international schools are free and open to all pupils. Six follow the European Schools curriculum, with French and English sections from primary (German too at Gaston Thorn), and some start at nursery level:
– École internationale Gaston Thorn, Luxembourg City
– École internationale Differdange et Esch-sur-Alzette (EIDE)
– Lënster Lycée International School, Junglinster
– École internationale Edward Steichen, Clervaux
– École internationale Mersch Anne Beffort
– École internationale Mondorf-les-Bains
The International School Michel Lucius offers English-language primary classes following the Cambridge curriculum. At secondary level, these six schools lead to the European Baccalaureate, four public lycées offer the International Baccalaureate, and one offers the Cambridge IGCSE and A levels.
Your commune does not allocate these places: you apply to the school directly, and at EIDE and Gaston Thorn this is done online on the school’s website. What their pages say:
– Timing: at EIDE and Gaston Thorn, the window for September 2026 ran from 1 to 15 March 2026. EIDE gives applications made in that window priority over late ones, and replies by email.
– Entry years: EIDE’s March window is for the first year of nursery, primary (P1) and secondary. Its P2 to P5 classes are full, and a place there opens only exceptionally.
– Conditions: Gaston Thorn’s primary criteria are living in or around Luxembourg City, having completed pre-school and turning 6 before 1 September of the enrolment year.
These were this year’s dates, not a fixed rule: when we checked in November 2026, these two schools had not yet published dates for September 2027. Rules differ from school to school, so check your chosen school’s website early in the year for the next window and open days.
The two European Schools, in Kirchberg and Mamer, are separate from these public schools: they are primarily intended for children of staff of the European institutions.
