If there is a colon between the terms this person may be a university student, because this is how people sometimes refer to it here in Brazil when asked what they do.

As you can see in this example of a brazilian marriage certificate, there is no punctuation, and it is filledout according to what was declared to the notary officer:

So in this case, I would really expect the person to be a student, because a professor or other employee would most probably give their title. And for cultural reasons and the little number of universities available for the number of students, many people also consider an achievement just the fact of being in university, and would declare it as an occupation.
