The gradebook can be hidden completely from students. A lecturer may choose to do this if they have not set up the gradebook, do not use it to track marks and do not want to confuse students with a large list of activities, some of which may be graded, some not; some may be assessable and some not.
From the unit's 'Administration' menu, select Administration > Unit administration > Edit settings.
In the 'Appearance' section of the settings page, change the 'Show gradebook to students' option to 'No'.
Click the 'Save and display' button.
Note: Hiding the gradebook does NOT hide the grades students have achieved in individual activities in the unit. Students can still see their marks or grades by visiting the activities directly in LEO.
