What we offer

Secondary education covers seven years of education with three language sections: a French-speaking section, an English-speaking section and a German-speaking section. These seven years are organized in three cycles:​ the observation cycle (S1-S3), the pre-orientation cycle (S4-S5) and the orientation cycle (S6- S7) leading to the Baccalaureate.

In September 2022, the École internationale Gaston Thorn will start with years S1 and S2 and will also host a class in the pre-vocational education class (Voie de préparation) and a Welcome class (Classe d'accueil).

S1-S3: Observation Cycle

For the first three years, students follow a common curriculum. Most subjects are taught in the mother tongue (Language 1). From S1 onward all pupils will begin to study a second foreign language (L3). In S3, Humanities and the subject “Life and Society” are taught in the first foreign Language (L2).

S4-S5: Pré-orientation cycle

In this cycle, the Integrated Science course is subdivided into three subjects: Physics, Chemistry and Biology. Students have the choice between a regular math course or an advanced course. Other options include Economics in Language 2, a third Foreign Language (Language 4), Arts Education, Musical Education, Latin and Luxembourgish.

S6-S7: Orientation cycle

Year 6 and Year 7 secondary classes form a unit, leading up to the European Baccalaureate. ​Although there is a core of compulsory subjects, students also have the choice of a wide range of electives which can be two hours per week, four hours per week or at an advanced level.
