User has reassigned a quiz from all students to one student. This has caused all student scores except the one student to be removed from the grade book.
When a quiz is extended for one student, instead of adding an additional Assign To criteria, the instructor has updated the existing Assign To criteria to only one student. If a quiz is not assigned to a student, the student cannot have a grade in the grade book even if the student already completed the quiz. To recover the grades, the quiz needs to be reassigned to the other students.
- Go to Quiz
- Click Edit
- Scroll Down to Assign
- Click Add at the bottom of the Assign To box
- Choose Assign to Everyone (this will display everyone else)
- Enter Due Date, Available From Date, and Until Date
- Click SAVE
- Now go to Grade book and verify the grades are now available.
