Use Late Policies To Automatically Grade Missing Assignments
Canvas automatically generates a running total of each student’s current grade. However, this only includes assignments that have a grade entered. If no grade is entered, the assignment is not counted in the Total grade calculation, which can lead to students misunderstanding their current grade.
To ensure an accurate point total/percentage, be sure to use Late Policies to automatically enter a “O” for all missed assignments. The instructor can manually update the grade later if the assignment is submitted past the Due Date.
NOTE: The default value for a missing assignment is set to 100%. This should be changed to 0%.
See the Canvas Guide:
NOTE: The Treat ungraded as zero option in the Gradebook only affects the instructor view, and does not actually adjust the point total. It also is for all items in the Gradebook, not individual assessments.
