The language of instruction is English in the form of "flexible monolingualism". The first three months of Year 1 take the form of an intensive phase of language acquisition after which the students have reached a level of language competence which enables them to participate in lessons conducted in the target language. Following the intensive phase, linguistic back-up for other subjects is provided when required in the English class. In Year 7 History is taught in French.

During the first five school years in particular, different subjects collaborate on broad projects that supplement language instruction. Between Year 6 and Year 8, the upper level course system ensures the interconnection and deepening of learning material. Students from non-German speaking countries receive instruction in German as a foreign language. Their evaluation is in accordance to § 18/12 of the School Instruction Guidelines which allows students to select either German or English as their first language of instruction and be thereby assessed accordingly.
