Grading history allows you to see who graded each assignment and revert scores for students. For quizzes, you can view historical data for any regraded quizzes.

Notes:

• Grading history only displays up to 2000 grade changes.
• Grading history may be unavailable in large enrollment courses.

By default, Canvas allows students to see assignment grades as soon as the instructor has graded the assignment. In some cases, instructors may wish to hold student grades until all assignments have been graded, and then release grades to all students at the same time. To hide student grades temporarily, an instructor can choose to mark an assignment as "muted". Students can still see and submit a muted assignment. Only the grade will be hidden. You can also mute assignments in SpeedGrader.

A muted assignment will not send out grade change notifications or any new instructor comments until the assignment is unmuted. A muted assignment displays a "mute" icon on the student grades page so students know the assignment is muted. Students will be unable to view their grades, including grade and score changes, submission comments, and curved assignments for the assignment until the assignment is unmuted.

Muting should only be used to temporarily block grading work in progress from student view. It should not be used to conceal grades for longer than reasonably necessary.

If you do not want students to be able to view their total grade, you can hide the total grade from students.

Notes:

• If you make changes to a muted assignment, the total score as you see it (in both the Gradebook and the student Grades page) will be affected. However, students will not see any changes when they view their Grades page. Once you unmute the assignment, the total grade in the student's view will update accordingly.
• If you unmute an assignment with varied due dates, all students will receive score results at the same time.
• Viewing the Total Column in the Gradebook may be restricted when multiple grading periods are enabled.
• Students will not be able to see their quiz responses while a quiz is muted.

You can use a Notes column in the Gradebook to keep track of extra information in your course, such as SIS IDs or just general student notes. The Notes column is not visible to students.

Note: Instructors can only show and hide the Notes column. Admins can use the API to create additional columns, but they cannot be hidden. Additionally, the Notes column and any additional columns are not included in the Gradebook CSV export file.
