My notes are from the 17-18 audition year.
In 2018 cycle, (for their MT class of 2022):
Elon had 1,051 applicants, passed 1/3 from pre-screens (~350) for 20 spots. I think they made about 35 offers. Elon only offered on campus auditions.
Florida State pre screens about 900 for about 240 live audition spots if I remember correctly. They made about 12 offers and end up with class sizes between 6-10. They used to only do on campus auditions but now they go to Moonifieds so that overall number is increasing.
TCU auditions about 800 and makes between 18-25 offers for a class size of about 12-14.
Ball State auditions about 1200 and made about 60 offers for 25-30 final spots.
I think BoCo is in the 1500 range but they made about 200 offers for a class of 60.
