How do I link a student to an observer in a course?
If you have the correct permissions from your administrator, you can link a student to an observer from the People page. When an observer is linked to a student, the observer can observe the student's activities and grades in the course.
Depending on permissions, you may also be able to link a student to an observer by using a pairing code. Using a pairing code will link the observer to the student in all of the student's courses.
Locate Observer

In the search field [1], search for the name of the observer. You can also filter by observer role in the Roles drop-down menu [2].
