Most University of Maryland classes have been moved online for the winter term, according to a campuswide email Wednesday from university President Darryll Pines and Provost Jennifer King Rice.

For the few classes remaining in person, students and instructors must wear KN95 masks, according to the email. Instructors and students must also submit a negative COVID-19 test before their first in-person class. The university will provide more information in a separate email, Pines and Rice wrote.

The university will continue to monitor COVID-19 trends and data on campus and in the community, according to the email. Decisions about the spring semester will be made in early January.

Pines and Rice encouraged the community to get their booster shots to reduce the spread of the virus and keep hospitalizations and cases of serious illness low.

Last week, Pines announced the cancellation of winter commencement, as well as required students and instructors to wear KN95 masks for in-person final exams. Dining halls and the Stamp Student Union food court shifted to a carry-out format for the remainder of the semester.
