Stanford Summer Session usually serves Stanford students as well as visiting students from other schools all over the world. However, because this year the university is using all four quarters as regular academic quarters, for Summer 2021 only, Stanford students can not enroll in classes delivered by Stanford Summer Session.
For Summer 2021, Stanford students will enroll in a 10-week quarter that begins on June 21 and ends on August 27. Summer Session will run a separate, simultaneous online-only 8-week quarter for visiting students only, from June 19-August 15.
Stanford students should enroll through Axess, which opens for course enrollment on May 23, 2021 for matriculated Stanford students.
