Edit a rubric
Note: You may only edit rubrics which are local to your site, and which have not been associated with an item for grading. Once a rubric is in use, it will appear with a lock icon next to it, indicating that it cannot be edited.
Go to Rubrics
Select the Rubrics tool from the tool menu of your site.
Select the title of the rubric you would like to edit to expand it
Remember: Locked rubrics may not be edited!
The Lock icon indicates that a rubric is associated with an activity in the site and it cannot be edited. If you need to edit a locked rubric, you should either detach it from the activity where it is being used, or make a copy of the rubric and edit the copy.
You may view and edit the rubric from this screen
