Are residency programs required to inform you of rejection for interview?

My gf is in the process of being informed about interviews for ENT residency, of which she applied to some 90 schools, and because I'm planning to move where she matches, I'm monitoring the list as interviews and rejections come in, just so I can know what my final destination might look like. So far something along lines of 7 rejections, 3 interviews, and 1 wait-list. Are the programs required to inform you yes or no if you get an interview? Or could she get through the entire process and... Are residency programs required to inform you of rejection for interview?
