There is no Quick Grading option when using grading guides or rubrics.
Accessing the assignment grading rubric
Go to the course homepage.
Find the assignment you want to grade and click its link.
Click View⁄grade all submissions in the center of the page.
Click the Grade icon in the grade column for a user.
Review the student submission.
Scroll down to the rubric.
Click the appropriate level to indicate your evaluation of each criterion. The level you select will turn a shaded green color. Click the level again to deselect it, or click a different level for that criterion.
Moodle sums the points given to each selected criterion, calculates a percentage of the maximum possible points, and applies that percentage to the full value of the assignment.
That score is sent to the gradebook.
Enter comments in the final column for any specific criterion if desired.
