I did not apply to Iowa, but I am currently a student at Vanderbilt! The stats they gave for my incoming class at orientation (includes AuD, SLP, Deaf Ed, and PhD) had an average 316 on the GRE and 3.9 GPA. As with any school though, these are certainly not the only things any school looks at. I will also say that some of my friends are at Vanderbilt but didn't get in to other programs they had applied to- it really depends!
