Summer Session 2021 Schedule

Visit the Academic Calendar for registration dates and deadlines for summer term.

Summer Session 2021 Digital Planning Guide (pdf) (Updated 6/10/2021)

Please note, a previous version of the Digital Planning Guide had an incorrect date listed for the Session 3 Add deadline -
this has been corrected in the updated version linked above.


Summer Session is comprised of over 1,200 undergraduate and graduate level classes, offered during 6 sessions throughout summer term. 


Summer Session is one academic term, however it is organized into multiple sessions so that courses can be offered with flexibility. In addition to term length classes (scheduled during Session 1), sessions allow accelerated classes to be offered exclusively over the summer. Each session has different requirements and deadlines, visit the deadlines page to learn more. 

While the summer calendar lists session dates, it is important to note that:

  • There are four different start dates for summer session courses, depending on the session.
  • There is no "dead week" (pre-finals week) during summer session, as in regular academic terms.
  • Final exams are usually given during the last week of class. Check with your instructor for specifics.


For more information on registration, visit the Registration page.

While the content of all summer classes is equivalent to a regular 11-week term, many summer courses are offered in accelerated sessions that last one, three, four or eight weeks. Check classroom meeting times in the course description, as these accelerated sessions typically meet for longer hours than during a standard term.

Course offerings vary based on the session in which they are assigned. 

Online summer classes are also available, and are administered via OSU Ecampus
