Schrodinger, I think the OP was asking about their Audiology programs.
I'm sorry, Anica, I'm not familiar with either of those programs.
From what I gathered, USU is focused on educational audiology and tele-audiology. I did not see a PhD listing on their site. UofU, on the other hand, offers both AuD and PhD degrees. I also noticed that UofU has an on-site clinic. USU has the Utah State Development Center but I'm not sure if that's on-campus or off-site. Information was harder to find on USU.
Caveat: I'm a bit prejudiced when it comes to university websites; I take their user-friendliness, frequency of updates, and information available as a reflection of the program. I know that's a bad idea because in reality they're probably not correlated, but I can't help it.
