It is easy to assign managers to a population of students. If you are starting with a new LMS, the User Import Template provides a column for Manager and Alternate Managers. The User Import tool will assign the manager listed for each employee. When you go into an employee’s user profile, you will see all the managers listed for that individual. The User Import tool will also prevent circular managerial assignment, meaning a subordinate cannot be a manager to his manager.
Add manager relationships between existing users by editing their User Profile, clicking the the "Managers" component and adding selecting a their manager's Username. In the screenshot below, one manager has been assigned through user import and the administrator is adding additional manager with the "Select a Manager" tool.
