Summer Session 2021 will be held entirely online. Learn about online learning and browse the course roster.

For students registered in summer part-time study

Due to COVID-19, students enrolling in part-time study for Summer 2021 may register only for courses that may be completed entirely online. They may not participate in classes that contain in-person components.

To determine if a course will be taught online, find your course on the Summer course roster and look for “instruction mode.” If a course lists the instruction mode as “OL/Online Learning” or “AD/Asynchronous distance learning” you may register.

Definitions of instruction modes
  • OL/Online Learning: The course will be delivered completely online with portions delivered synchronously at prescheduled course meeting times. Students are expected to participate synchronously as long as the scheduled meeting time is between 8 a.m. and 10:30 p.m. in their local time zone.
  • AD/Asynchronous distance learning: All students and instructors interact online. Involves well-designed, pre-recorded content and curated asynchronous interaction. Content is accessed by students at unspecified times.
