If you have enabled the Launch SpeedGrader Filtered by Student Group setting in course details, you must select a student group before opening SpeedGrader from an assignment or quiz. To select a student group, click the Select Group to Grade drop-down menu.
Note: When this option is enabled, certain areas that open SpeedGrader will prompt you to select a student group to view in SpeedGrader. In areas that do not provide this option, SpeedGrader will open filtered to the first group that contains students. You can change the student group that opens by first selecting a student group in the New Gradebook. However, if you open SpeedGrader for a specific student, SpeedGrader will open filtered by the first available student group in which the student is a member. Additionally, if you open SpeedGrader from a specific student who is not a member of a student group, group filters will not be applied.
