Canvas: Changing the Status of a Submission in the Gradebook
As needed, instructors can use the Grade Detail Tray to change the status of an assignment, discussion or quiz submission for students. Available statuses include: "None" (no status), "Late", "Missing" or "Excused". You can also change the status for a group assignment. Assignments with a "Late" or "Missing" status will display a label on the student's Grades page indicating the status. If you do not want status labels displayed on a student's Grades page, set the assignment status to "None". "Excused" assignments are not calculated as part of a student's total grade. Currently, points are not automatically deducted for assignments with a "Late" status.
1. From the course navigation bar, click Grades.

2. Locate the student's name and assignment where you want to change the status. Click the Gradebook cell and click the Grade Detail Tray icon. Click the box where the grade was rewarded and select the arrow.

3. The Status section of the Grade Detail Tray displays available status options: "None" (no status), "Late", "Missing" or "Excused". If you do not want status labels displayed on a student's Grades page, set the assignment status to "None".
