: Hi, thanks for your note. Can I just say that we have a policy here of trying to follow whatever is the most commonly form in English. For a word and concept that is so clearly non-English this may be a difficult criterion to apply, but maybe before we make a decision we ought to look around a bit to see if there's any established convention of how to call the thing in English sources? (For instance, there must be sources in English published by international or English-speaking institutions about international recognition and equivalence of these degrees, so we might look at what they are calling it.)
