Grades min max

Summary

When grading in Moodle, either in an activity or directly in the gradebook, you assign the student a score from a specified range. For example the assignment maximum grade is set to 10 and you give the student 5 points out of 10 ( 50 %).

The setting "Min and max grades used in calculation" defines how grades should be displayed and aggregated when the maximum grade for the assignment is changed after students have already been graded. The 2 possibilities are:

1) "Min and max grades as specified in grade item settings" - The students grade will be displayed out of the new range, and this will affect their percentage. E.g. if the maximum grade was changed to 20 in the example above (after the student was graded), the students grade would show 5 out of 20 ( 25 % ).

2) "Initial min and max grades" - The students grades are displayed with the range that was defined at the time the student was graded. E.g. if the maximum grade was changed to 20 in the example above (after the student was graded), the students grade would still show 5 out of 10 ( 50 % ) until a teacher manually regraded that student out of 20.

Information for upgrades

Note: The default behaviour in Moodle is the "Min and max grades as specified in grade item settings". In Moodle 2.8.0 - 2.8.6 and 2.9.0 the behaviour was un-intentionally changed to "Initial min and max grades". In Moodle 2.8.7 and Moodle 2.9.1 it was restored to "Min and max grades as specified in grade item settings" and this setting was added to allow changing the behaviour.
