Some poor bugger at Playbill went through the resumes of every Broadway actor during the 2022-23 season (from May 2022 to April 2023) to see which college or university they went to. The top ten institutions represented on the Great White Way last year via their alumni are:

1. New York University (NYU) - by a considerable margin by the looks of it
2. University of Michigan
3. American Musical and Dramatic Academy
4. Carnegie Mellon
5. Yale
6. Juilliard
7. Boston Conservatory
8. University of Cincinnati College Conservatory of Music
9. Pace
10. Northwestern

Honourable mentions include Penn State, Elon, Syracuse and the only non-American institution - London Academy of Music and Dramatic Art (LAMDA).

Some performers are alumni of multiple institutions, for example Victoria Clark graduated from both Yale (BA) and NYU (MFA), so both unis can claim her.
