If you can’t add comments to or grade assignments, this is usually caused by the Post date having been reached. The Post Date is the date students receive their feedback and marks and anonymous assignments become un-anonymised. To mark or add comments you need to change the Post Date to a date in the future:
- Click on the assignment name in Moodle
- In the Summary tab click the pen icon on the right.
- Change the Post date to a date in the future.
- Click the tick icon to save the change.
You should now be able to mark and comment on assignments.
