Answer:
You can create rubrics either within a specific course or system-wide to reuse later.
To create a course-specific rubric, go to Course Details → Rubrics and click New Rubric.
Enter the rubric name, description, and add rows and columns to define criteria and levels.
Once saved, it can be attached to grade items in that course.
To create a reusable rubric for any course, go to Home → Rubrics and click New Rubric.
Rubrics created here will appear as options when adding grade items across the system.
