How do I mute or unmute an assignment in SpeedGrader?

By default, Canvas allows students to see assignment grades as soon as you have graded the assignment. In some cases, however, you 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, you can choose to mark an assignment as "muted". You can also mute assignments in the Gradebook.

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. Learn how students see muted assignments.

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.


  • 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.
