I would also like to be able to send a list of missing assignments to students/parents via a report or email template.
The gradebook report will display unsubmitted work. But we don't have a report currently available that will display missing assignments.
It only tells how many students are missing it. It doesn't say who has not submitted it. I think we are all looking for a report that would have the student's name and all the assignments they still need to complete or retry.
