German and English are the two school languages taught across all levels. The curriculum supports language development in both German and English with a bilingual reading and writing curriculum in the Primary School. Primary education follows the Hessian core curriculum, and Secondary School leads to the German Abitur and may offer the International Baccalaureate Diploma Programme.

Bilingual Teaching

From Reception Programme through to Secondary School, SIS Frankfurt offers bilingual education. Subjects are taught in German and English at all levels. From day one, instruction is delivered bilingually by native German and English-speaking teachers. Secondary School prepares students for the German Abitur and, optionally, the International Baccalaureate Diploma.

Immersion Programs

Immersion is central to instruction, with a bilingual Reception Programme where English and German are taught by rotating teachers. In Primary School, each class has a German-speaking and an English-speaking teacher, delivering instruction in both languages daily. Core subjects, including mathematics and social studies, are taught in both languages, reinforcing bilingual fluency.
