Moving Scores from a Mastery Report (affects one student at a time)
It may be easier to move scores from within the context of a mastery report (especially if you are an administrator). This also works to move ALL grades, regardless of unit/assessment, from one course to another (the option in the Grade tab only moves scores for one assessment at a time). To move scores from a mastery report, first load the Mastery tab for a student. Then, from the settings menu in the top right, choose Advanced Options and then check the "Clean Grades Mode" option. NOTE: Your account must have Backoffice module permission to access this feature.
Next to each course, you can choose to move the grades. Begin typing a course name in the dialog box and carefully select the destination course from the list and click Move Scores, and you're done!
