I think it is fair to say that any audition BFA program that ends up on any of the many so-called “top schools for theatre majors” lists is likely to be one that is “hard” to get into. I will leave it to others to sort through where on the hard to OMG scale various schools should be placed. I can tell you this, though, that any of us who had children receive an acceptance from any of the audition-BFA schools on the list above likely said OMG at the time!
The other thing I would say is that many of the same kids apply to many of the same schools, and you only need one. And unlike a more academically-oriented admissions process, they are somewhat more like independent rolls of the dice. By this I mean that if a student is admitted at Harvard, Princeton, and Yale, I would imagine that they are likely to get admitted to Brown and Dartmouth, too. However, getting accepted or rejected at any particular tip top BFA program is more of an independent event, in my opinion. Otherwise, there would be no way to explain the fact that many students get into some schools and rejected by others in a way that appears more random than anything. Student A gets into School A, and not School B. Student B gets into School B, and not School A.
So, my advice to anyone entering this process is to cast a wide net. Work to find many schools that are a potential fit - by many I mean like 15 schools. And do your best on each application and each audition. Good luck searching for your own OMG moment!
