In several posts, as contributors compare distance learning graduate programs, many speak of the "rigor" of the program as a measure of its quality. I have the sense though that the term is highly subjective. I'm curious as to what different posters consider rigor. Is it volume of coursework? Is it difficulty of the exams? Is it the quantity/quality of the bibliographic sources for research? If it is volume of work, then I would question how quantity automatically translates into quality. If it is the difficulty level of the exams, then one person's rigor is another's ease. Well, you get the idea. As I navigate the waters towards selection of a doctoral program, I've been considering the advice of those who tout their alma mater as bastions of "rigor." Perhaps some of you can tell me just how you measure that. Thanks.
