It depends on the school and whether their academic admission separate from the audition or not. Every school is a little different and the academic and artistic notifications can come separate or together, depending on school. If you don’t see the specific words that you’ve been accepted as a insert major you’re auditioning for here student, then it’s only academic.
Some schools will not admit you unless you are accepted into the program you audition for, but others might give you academic acceptance (with honors college and lots of merit!!) before you even hear about the prescreen. Or even after you’ve been given a “no.” Some of the ones that reject you artistically will aggressively try to get you to enroll anyway…
Many times, if academic admission is tied to the audition, it will say so somewhere on the college’s website; such as where the audition info is. Emerson is one of those; they say they weight academic and audition equally before making a decision.
Another example is Wagner, which has you apply academically, and if you will be accepted for academics, you will be invited to audition.
Best of luck, it’s stressful sorting those out, and so hard to get a big fat envelope and realize it has nothing to do with artistic admission.
