As a general rule, either English or German is determined as the official work language.
If the research project is going to be worked on in German, advanced German skills are necessary. Language exams are not obligatory, but language skills should be at the TestDaF level (Niveaustufe 4 or 5) or DSH (Deutsche Sprachprüfung für den Hochschulzugang).
Should you attend conferences or events at the University, solid German skills are undoubtedly vital. This is particularly true, if you need to read German texts or even compose texts in German for your work.
If English is chosen as the work language, you will likewise require advanced English skills, if you are not from an Anglophone country. We therefore highly recommend that you acquire appropriate language skills before starting your job or doctoral studies.
Learning German and Language Courses
To be able to manage everyday life in Germany right off the start, it is best if you have already acquired basic knowledge of the German language before entering the country.
If your German skills are still rough when you arrive in Aachen, we recommend registering for a language course as soon as possible. Although most staff and students at the University can speak English, the success of your stay is often dependent on you learning German or improving your German skills – good communication skills will make your everyday life as well as interactions with authorities, colleagues, and other people you will meet much easier and will also helps with your work.
