Manage Rubrics
Copy rubric
After you use a rubric for grading, you can't edit it, but you can make a copy that you can edit and rename.
Go to your gradebook. Select the Settings icon to bring up the Gradebook Settings panel. Scroll down to the Course Rubrics section.

Access a rubric's menu by selecting the three-dot icon and then select Duplicate. The copied rubric opens with the date and "copy" added to the title. You can make edits as needed. Select Save to save the duplicate rubric.
Note
Note: If you copy an existing percentage-based rubric and change it to a percentage-range rubric, all the descriptions are cleared.
If you've already used a rubric to grade an item, you can also copy the rubric and edit the duplicate version. From an item's Settings panel, open the rubric. Select Create a Copy at the bottom of the screen. When you create a copy of a rubric you used to grade a test or assignment, the new rubric is associated with the item. Any grades calculated with the original rubric are preserved, but these grades are converted to overrides. You can regrade these submissions with the new rubric.
Important
You can't copy rubrics on small devices.
Copy rubrics between courses
You can copy rubrics between your courses. On the Course Content page, select the plus sign to open the menu and select Copy Content. Or, open the More options menu above the content list. Select Copy Items. The Copy Items panel opens.
From the Copy Items panel, you can browse all the courses that you teach. Select the Rubrics folder for the course you want to copy rubrics from and select the rubrics you’d like to copy. When you’re done, select Start copy.

Delete rubrics
You can permanently delete a rubric from your course even if you used it in grading and the grades will remain. The grades are no longer associated with the rubric, but now appear as grades you added manually.
To permanently delete a rubric, open the Gradebook Settings panel in your gradebook.
