Good undergrad places in the North East?

I need advice for a student. She currently attends SUNY Potsdam/ Clarkson University, but she would like to be a voice major and needs another year or two of study to get to the level of someplace like the Crane School.
Can anyone recommend teachers/schools in the NY State/New England area? I live in Virginia, so I'm a little out of my element here.
-Thanks!
