For whatever it is worth (maybe not much), the people who review and rank graduate schools of all kinds including MFA photo programs, have ranked the University of New Mexico and the Art Institute of Chicago in the top three (actual position varies) for the last twenty plus years. The third of the top three has varied greatly, but it has never included any ivy league schools that I can remember. The third school in the trio has included RIT, UCLA, University of Arizona, RISD, U of Illinois at Champange Urbana and NYU(I think?)-I can't remember more. It is based on the quality of the faculty, fascilities, curriculum and resources in the community like museums etc. based on reviews by graduates and university professors nationwide.
