Most Penn undergraduates won’t be coming back to campus this fall, the university announced yesterday.

The university revised its plan for on-campus undergraduate housing for the 2020 Fall semester due to continuous spread of COVID-19. The revised plan was announced on Tuesday and now includes very limited on-campus housing for the Fall semester for international students and students experiencing significant housing or personal hardships.

Penn announced earlier this summer that the majority of instruction for undergraduate students would be online during the Fall semester, but the plan allowed for students to move onto campus. 

There will be no physical on-campus activities in the fall, according to the announcement, and Penn has encouraged undergraduate students not to return to Philadelphia. Some 10,000 undergraduate students attend the university.

“The progression of the disease is evident in many states from which Penn welcomes thousands of students,” President Amy Gutmann said in yesterday’s statement.

“The sheer number of students who by Pennsylvania public health recommendation would now upon arrival—or based upon testing or high-risk exposure—need to go into a two-week quarantine is untenable. At the same time, supply chain issues have more severely limited the availability and the turn-around time of COVID testing than medical experts foresaw. Since we last communicated we learned that our planned pre-testing regimen would not be possible.”
