From the website:

"The goal of Columbia's graduate program in Yiddish Studies is to train future researchers and university teachers of Yiddish language and literature. Additionally, graduates will be able to serve the needs of museums, archives, schools, community centers, other cultural and communal institutions worldwide. Finally, knowledge acquired in the program may also provide the basis for creative endeavors by writers, translators, musicians, singers, and actors. Columbia University offers the M.A., M.Phil., and Ph.D. degrees in Yiddish Studies."
