EDIT: I originally titled this "Master of Architecture student" or "Master of Architecture candidate"? My apologies if the question was unclear, I couldn't think of a better title at the time, I hope this title is clearer. I'm not asking the definition of "candidate" vs. "student". Despite being a less common usage, "candidate" is sometimes used to describe students who are working towards a degree.
My question is about achieving the correct formal tone and concision for the context: a business card. A full sentence seems inappropriate in such a context, and I'm hoping to avoid acronyms because they are typically meaningless to those outside the discipline.
I'm looking for the right, concise way to indicate current enrollment in multiple specific master's degree program on a business card. I sometimes see "candidate" used for master's students, but it seems much more common for PhD students. Does "candidate" denote something more specific than "student" in this context?
Furthermore, if one were enrolled simultaneously in two master's programs, would it be appropriate to combine the two into "Master of Architecture and City Planning student" or "Master of Architecture and Master of City Planning student"?
