Not for BE, no. That's because the concept of an 'apprenticeship' is now largely something from the dim and distant past. Very few people can now be called 'apprentices'.

Something like 'commercial training' or simply 'business training' is probably what you're after. And the people doing such training would then be 'trainees'.

In a CV you could put '1990 - 1993 Industrial business management trainee' (or just 'Management trainee')

I didn't know that "apprenticeship" ist outdated. Thank you for your prompt replies!

Does Ausbildung have to be below Studium?

How about "studied Business Administration & Economics"?
