You are free to search for your own traineeship, although some faculties/departments also have internship positions on offer. They stem from established contacts abroad or in the context of ongoing research. The internship must be in line with your studies, or vocational interest. The internship lasts min. 2 months and max. 12 months during one academic year. You can either do an internship during the academic year or during the summer months on your own initiative with a possible recognition during the next academic year (eg exemption for some credits).
