Do people always get a Master's Degree before they get a PhD? I have noticed that some people will list in their credentials 1) the university where they got their undergraduate degree, and then 2) the university where they got their PhD, but there is nothing listed for the M.A. or M.S. I always thought it was required to do the Masters first, but maybe it varies from program to program? Or maybe they just didn't bother to list where the Masters degree came from if it was from the same institution where the PhD was received?
