Blackboard’s Grade Center comes with the functionality to hide columns (graded activities) in a couple different ways. It’s good to understand this, even if you don’t plan to use it, just to get a better feel for the system and another troubleshooting tool in your toolbox.
If you notice a circle-with-a-red-slash icon next to a column header, this means that students can’t see this column in their My Grades view.
If you’d like to turn this feature on or off, click on the chevron icon to the right of the column header and then on “Hide from Students (on/off).” Turning it “off” will mean that the red circle goes away.
You can also hide columns from instructor view. To do this (or if you suspect this is happening), go to the Full Grade Center, and then Manage > Column Organization.
From here, show or hide a column by clicking the box next to its name and then either show or hide under the Show/Hide button. (You can also hide from the full grade center, but not show.)
