CHAPEL HILL (AP) — The flagship school of North Carolina’s university system announced Thursday that it is delaying the start of in-person undergraduate classes for the spring semester, citing record numbers for COVID-19 and hospitalizations.

The University of North Carolina at Chapel Hill said in a statement on its webpage that while classes will begin on Jan. 19 as scheduled, it is delaying the start of in-person undergraduate classes for three weeks. Chancellor Kevin Guskiewicz said only a limited number of undergraduate courses were planned for in-person instruction. He said start dates for graduate and professional programs may vary and all programs have the option of starting remotely.

Students can return to campus residence halls beginning Jan. 13 as planned, but students will have the option to return or delay their move-in date up until Feb. 7, the day before classes are to begin. All students will be in single-occupancy rooms, and housing fees will be prorated according to when students choose to move in.
