Instructors can view Enrollees who are enrolled in their Class(es) and on the Unassigned list on the Classes page. They can also see Enrollees' Account information. However, they can only manage Classes they are either assigned to or have access to.
Add to Classes or Access All Classes
You will need to make sure the Instructor is added to the Class(es) on the Classes page. See this support article for how to add an Instructor to a Class.
Instructors can also have access to all Classes. Go to the Instructors page and click the blue pencil icon beside the Instructor's name. Select the box "Can access all Classes" under Roles:
Manage Classes Permission
You will also need to make sure that within their Role, they have the permission "Manage Classes" (as seen below) selected so that they can edit Classes:
Manage Unssigned Enrollees
For Instructors to NOT be able to view the Unassigned List on the Classes page, the following permissions must be turned off (unchecked) on their Instructor Profile:
"View Unassigned"
"Manage Classes"
Instructors will still be able to view the number of unassigned Enrollees signified by the number in a red circle, but will not be able to view the list itself.
How to View Class Capacity
Instructors can view Class capacities on the Classes page if the following is true:
1 - They have the permission turned on ("Manage Classes" permission)
2- They are an instructor for that class (or have "access all classes" turned on)
3- They have access to the same location the class is in
