In the U.S.: degree prgram student or "credit by exam" student
I am basing my answer on the definition provided in the previous answer. If you need a translation for a U.S. audience, you will have to use an explanatory expression, as there is no direct equivalent. U.S. institutions want to get paid for the courses they offer, in exchange for any degrees they grant!
According to what I've found doing a Google search, a *non-collegiate* student is one who earns a degree in a British-style university by taking the exit exams. You can't do this in the U.S., but, theoretically at least, you could take a lot of exams for course credit, and get most of your college credits that way. In the U.S., the exams used are usually CLEP (College Level Equivalence Examination).
