I agree with @TexasMTDad; most important is the combination of her talent and commitment. Her summer program will hopefully give her a sense of what a collegiate environment is like – so she can test the waters and see if it is to her liking. Clearly your D has a lot of talents so in addition to MT, she can consider Acting, Vocal Performance and perhaps other majors too. Best of fortune to your D in whatever route she chooses.
