You should check old posts as we have covered this before.
Which school is the best depends on which school is the best for you (you skill level know, your interests in where you want to go, etc, etc). There is no best school.
Look at the following schools . . .
Yale
UCSD
UCI
Cal Arts
U of Deleware
Rutgers
University of Alabama/Alabama Shakespeare
CC of Music
UM/Kansas City
UI Urbana Champagne
I have links to some of these schools on my web site:
http://www.stagemanager.net/Resources.htmlI can answer questions about UCSD, as that is where I went to school, and many people can offer advice, but be warey of anyone saying one school is better then the other with knowing more about you.
