How do I set a course submission comment for a Turnitin Assignment?
The account administrator can set a standard comment that all students will see when turning in a Turnitin-enabled assignment.
Course instructors can add their own personal message to be shown for any assignments in their course.
Note: These steps are only applicable for the Turnitin Plugin in Canvas. If you have questions regarding the Turnitin LTI, please contact Turnitin.
