I did not see this in my search.
It would be nice if the Rubric Tool allowed negative numbers in the descriptors for a Criteria. We have a policy of deducting points from papers that are one day, five days, or more than five days late.
If negative numbers were allowed then there could be a Criteria line for Lateness that is 0, -10, -20 points and student would usually get a 0.
We are currently using Moodle plain 2.7.9
