If you automatically assign peer reviews, Canvas will assign peer reviews to students automatically once they have submitted their own discussion reply.

You can also tell Canvas to automatically assign peer reviews after an assignment due date has passed.

Notes:

• It may take up to one hour for Canvas to assign peer reviews.
• When using peer reviews with Groups, it is best practice to manually assign peer review discussions to students. Additionally, if the student has not submitted the assignment or submits the assignment after the due date, the student will not automatically be assigned a peer review and you must manually assign one.
