I'm chiming in a bit late on this one, but I think the name for this is
"[[degree completion]]" - a program for professionals and others who
have done a lot of learning on their own and want official academic
credit for it.
There are CLEP tests and the Graduate Record Exam (GRE). My church's
seminary has had a degree completion program for the last 15 years or
so; when you finish the tests, you get a Regents Diploma which is pretty
much accepted by any graduate school as a bona fide bachelor's degree.
A "diploma mill" is a non-accredited program which awards a degree which
is NOT generally accepted.
