LOS ANGELES >> Amid the alarming surge in coronavirus spread, the University of Southern California announced it will no longer bring all undergraduates back to campus for the fall semester and will move to mainly online classes, reversing an earlier decision to welcome students back for a hybrid model.

The decision, announced by Provost Charles Zukoski late Wednesday night, came the same day Gov. Gavin Newsom announced tougher restrictions on indoor activities. Zukoski recommended that students not return to campus for the semester and instead continue their education online.

“The once-in-a-century COVID-19 pandemic has altered every aspect of our lives — the way we interact, work, and socialize — and with each new permutation of the pandemic, we must find ways to thrive,” Zukoski wrote.

“Given the continuing safety restrictions and limited densities permissible on campus, our undergraduate students primarily or exclusively will be taking their courses online in the fall term,” he said. “On-campus housing and activities will be limited.”

Only 10% to 20% of courses during the fall semester will be conducted in person and on campus. These courses include certain labs, studios and performance classes and research studies that require hands-on work.

The new USC decision echoes the University of California, Los Angeles’ plan for the fall to only offer 15% to 20% of courses on campus, and reflects how colleges throughout the state and nation are moving to severely limit in-person courses, continue with online learning and dramatically alter student life during the pandemic.

Both the California State University system — the largest four-year university system in the nation — and the Los Angeles Community College District have also moved the vast majority of their classes online in the fall.

Students who struggle to connect off campus will also be able to apply for a one-time scholarship providing up to two free classes for the 2021 summer session “to help ensure academic progress.” USC said it will also expand its financial and technical support for students with connectivity issues.

Students with on-campus housing contracts will be allowed to cancel them through July 15. For students who need to live on campus, only one student will be permitted per bedroom. Those living near campus will be required to make an appointment to use library spaces or dining facilities, the email read.

“Whether students are here on campus or pursuing their studies and activities online, we want everyone to feel safe and supported,” Zukoski wrote. “We are in this together and together we will make this fall a rich and rewarding experience.”

The new decision comes just a month after USC President Carol L. Folt said students would be able to return to campus for the semester, and just three days after the university’s chief health officer revealed a plan to reduce the number of students in campus housing and check for symptoms on a daily basis, according to the Daily Trojan.
