This. I agree that there is an element of subjectivity to it (Is Cambridge better than Oxford?), but I think it is simply impossible to successfully defend the claim that (as an example) The University of Phoenix has made more contributions to computer science than, say, Berkeley.
One way — not the only way, but a reasonable way — to measure it is by the # of Turing Award laureates[0]. Cal Poly isn't even on the list. (Neither is it on the list of Nobel Prize winners, for what it's worth).
