One of my groups, BAs and technical school/apprentiships.
Other one, high school to associates, plus a bunch of college students.
I've the highest of the current lot, having taken most of a Master of Arts in Education. (Missing student teaching.)
None of my players have had a doctoral degree while playing at my table, but three have gone on to get them (one's a DC, one's a DN, one's an EdD.)
I've had a number of players over the years with Masters degrees while playing, and a few more have moved on and since gotten masters degrees.
