Like other universities, though, Harvard promised to bring the classes of 2020 and 2021 back to celebrate at some future date.
Some universities plan to hold their commencements in outdoor stadiums. Notre Dame, which was aggressive about bringing students back to campus last fall, is planning to accommodate all 3,000 graduates and a limited number of guests in its 79,000-seat stadium. Health officials have authorized the use of up to 20 percent of the seating.
The University of Southern California will hold in-person ceremonies for the classes of 2021 and 2020 in May. The ceremonies will take place at the Los Angeles Memorial Coliseum and graduates will be allowed to invite two guests, although they must be California residents.
Northeastern University in Boston will host five commencement ceremonies in Fenway Park in May. Officials are aiming to allow each graduate to invite one guest, though they are still evaluating total capacity with physical distancing.
The latest on how the pandemic is reshaping education.
The University of South Florida in Tampa said on Monday that its commencement would take place at nearby Tropicana Field, which can hold about 40,000 people. The university set a tentative date of May 7 to 9. Students will be allowed to bring two guests and must register in advance.
Some schools are holding ceremonies without guests, in what will be largely empty stadiums.
The University of Wisconsin-Madison will hold in-person ceremonies in its Camp Randall Stadium, which can hold about 80,000 people. The university will hold two ceremonies on May 8, but graduates cannot bring guests.
Princeton plans to hold an outdoor commencement at its stadium for students who have taken part in the testing program and who live on or near campus. It is also considering extending the invitation to students learning virtually.
