That does sound like an impressive level of accomplishment in dance. Just one point since you mentioned UCLA, I don’t believe there’s any issue with applying both early at Stanford and at UCLA, since UCLA is (1) public and (2) doesn’t have an early option in any case.

Also unless UCLA uses Likely Letters or some other form of early indication of admission for dance (like what Stanford and some other schools use for recruited athletes) I don’t believe your daughter will get official word from the UCLA admissions office until next spring.
