You must assign the instructor role to a VMware Lab Platform user and associate the instructor with a lab.
The general workflow is as follows:
Using the Edit Account form, assign an existing user the role of instructor. Users assigned this role appear in a list accessible from the Create Class form. An instructor can monitor the progress of selected students (a class) taking a specified lab (instructor-led lab).
Using the InstructorLabMapping List to associate instructors with specific labs. By creating such instructor-lab associations, you can restrict instructors to access only specific labs. If you do not create any instructor-lab associations, then no instructor restrictions exist, and instructors are able to access any lab in the account.
Using the Create Class form, create a class. A class is composed of selected users (students) to take a specified lab, at a specified time and to be monitored by a specified instructor.
Instructor, by means of the Instructor Console, monitors the progress of each student in a class who has started the lab specified in the class.
