Canvas calls exempted grades "excused."  Excused assignments are not factored into the student's total grade, and the student will not be able to submit the excused assignments.  You can excuse a grade by selecting the specific student's cell in the gradebook and typing "EX." Alternatively, you can follow the steps in Canvas's How do I change the status of a submission in the New Gradebook? article.

Reviewing the grades

1. On the course navigation menu, select Grades.
2. Find the columns for each version of the exam. You can use the search bar at the top of the page to isolate these columns. For example, type "Exam 1" and select each version you find.
3. Review each row of the gradebook to determine which students need to be excused. (Explained next.)
   • If you see students with no grade or attempt in all of the columns, they missed their exam. Typically, this means you will give them a 0 on one of the columns and excuse them from the other columns.
   • If you see students with a grade or attempt in multiple columns, investigate further to determine which grade to excuse. We recommend only grading the first attempt and excuse the rest. If you do not have a policy developed for managing this scenario, you may want to contact these students to ask why they took the exam multiple ways and discourage them from doing this again.

Excusing the grades

1. Note the column and row and select the grade cell to be excused.
2. Type ex in the cell. Then, press Enter on your keyboard, or click on a different cell. 
3. Alternatively, if you want to avoid typing, click on the cell and select the arrow-surrounded-by-rectangle icon that appears in the right of the cell. In the panel that appears on the right of the screen, select the yellow excused radio button.
