Some summer classes might be canceled, a Pitt administrator said yesterday.

Michael Perloff, director of undergraduate studies and undergraduate adviser for the Department of Philosophy, said in an e-mail that University administration indicated enrollments for summer courses “are off. Classes are likely to be canceled.”

The e-mail was sent to all philosophy majors, but Perloff said that enrollment is currently low in classes across many departments.

Perloff said that if students plan on taking a course this summer, they should “sign up soon” in case more enrollments would be sufficient to prevent cancellations.
