Every class created on Turnitin has an end date. When the end date is reached, the class expires and is limited to read-only access and will no longer appear on the active classes list. The students and instructor will no longer be able to submit papers or peer reviews, create assignments, or mark any of the papers using GradeMark.
To view expired classes only, click on the Expired classes tab on the Turnitin instructor homepage. The All Classes tab, to the left of the Expired Classes tab, will list both active and expired classes.
