Coronavirus Update: USD will begin its fall semester Aug. 19 and conclude classroom instruction by Thanksgiving for most of its academic programs. The university is committed to on-campus operations this fall. USD will continue remote delivery through the summer academic term (May 18-Aug. 7). All USD-hosted events and visitor activities are canceled through July 31. USD plans to host graduation ceremonies on Saturday, Oct. 24, 2020, at the Sanford Coyote Sports Center.
