There is no way any one can give you the definitive answer to that. It will vary from school to school - as well as thru depts. You have to ask around at the schools she is considering - and that is likely something you can start doing in the fall. Also, no way we can tell you the right choice for your daughter. Some schools with a dance program will concentrate on classical types of dance which won't include dancing for the stage.
If she goes to a school in a major city, she can always take whatever classes she's missing from the choice she's made. (ie. A ballet class if she goes MT, voice classes if she goes dance) I say cities since most of those offer classses that are of the drop in variety not requiring commitments. (Well, not voice, obv.)
If we're not having fun, then why are we doing it?
