D2L - Turning off Class Grade Average (UW-Madison)
When you create a gradebook item, it will, by default, show your students the average class grade for that gradebook item. To turn off the default, go to your gradebook and then click the down-facing arrow next to the gradebook item you want to change. Next click "edit" from the dropdown menu.
How to prevent your students from seeing the class average for an assignment or grade item in the gradebook.
In the window that opens up scroll down to the "Show Display Options" tab and click it.
Under "Display Options" make sure that the boxes next to "Display class average to users" and "Display grade distribution to users" are unchecked. (They are checked by default)
NOTE: There is no way to turn off this setting for the entire gradebook or class. You have to turn the default off each grade item individually, one at a time.
