DLL is aimed at teachers of German as a Foreign Language or German as a Second Language, with or without prior teaching experience.
Even without a degree in German or German as a Foreign Language, teachers can improve their skills by taking modules from the DLL series. To qualify for the course, participants must have B2-level German according to the Common European Framework of Reference for Languages (CEFR).
These units are especially beneficial for participants who already work as a teacher, have teaching experience or have completed work experience or classroom observations of German lessons.
