LMU offers teacher training programs ("Lehramtsstudiengänge") that are specifically tailored to fit the different school types of the Bavarian school system (in this case: Bavarian "Realschule").
This program as well as teaching at Bavarian schools as such presuppose German language competences at a high level. The final state exams ("Esrtes Staatsexamen", "Zweites Staatsexamen") are also held in German.
Please consult the German language version of this webpage for more information on the "Lehramt "Realschule" program.
