If you need to delete an assessment (all learner grades) this article will walk you through the necessary steps. Let's take a look.
First, you need to go to the View and Edit menu in the Gradebook and click on the List and Edit Grades option from the menu. This will display the list and edit screen.
You will see a list of all the assessments in that timeframe. If you cannot see the assessment you are looking for try adjusting the time frame to All Time. You can also filter the assessments by type or search by name.
Once you locate the assessment you want to delete, click the Actions button next to the assessment and click on Edit. This will display the Edit Gradebook screen.
Make sure this is the assessment that you want to delete.
Then scroll down to the bottom of the screen and click on the Delete Gradebook button. You will then be asked to confirm that you want to delete the Gradebook.
