I really wonder what these admissions committees look at. I also don't really take these "Top 10" school rankings to heart, I really think it is all a load of garbage. I'm at a wonderful consortium (techincally I go to three universities) and their rankings are not even published for Audiology and I know our facilities are top notch and the research, etc. is well known and cutting edge so I really take it with a grain of salt.
Anyways, as for the admissions committees, I know people who have a near perfect GPA but were rejected. They didn't have a lot of outside experience though (such as volunteer work and such). I think this has a lot to do with it. I believe you have to be very well rounded. I had a 3.98 undergrad GPA, not too amazing GRE scores (only scored a 980 overall with a 5.0 writing) but I work in a hospital in the Speech and Hearing Clinic doing the Newborn Infant Hearing Screenings. I'm sure that (along with my GPA) really helped me out a lot, in addition to the fact that I was president of NSSLHA and president of the Communications Honor Society at my undergraduate school. I think the committees really want to see their prospective students not just achieve in the classroom, but also outside of it.
