What English expression resembles the German "Tutor"? In Germany, it is common for students to hold “Tutor” positions, which entail a weekly teaching class (e.g., 90 minutes) and the correction of exercise sheets handed in by students.

I would like to list such a position in my CV, which is in English.

What English expression should be used for this type of work? Is teaching assistant suitable?
Firstly, even in Germany there are different word for this. Besides Tutor there is also wissenschaftliche/studentische Hilfskraft, HiWi (short for Hilfswissenschaftler but has apparently different meanings in other contexts) or Übungsgrupperleiter, for example, and the usage of these words may even vary between different parts of the university and their usage among students/faculty/administration is not always consistent. 

However, I think the most widely used term in English speaking countries is TA (teaching assistant).
