How do I mute an assignment in the Gradebook?

By default, Sublime LMS 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". 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.


  • If you make changes to a muted assignment, the overall 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 overall 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.

Students can still see and submit a muted assignment. Only the grade will be hidden.

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.
