Once you have added the appropriate number of licenses to your sub-coordinator account, follow these steps to add teachers under that sub-coordinator:
Find the teacher you would like to move under the sub-coordinator.
Click the vertical ellipses to the far right, then select Edit.
Under “Who will manage this user’s license(s)?”, click the carrot in the drop-down window and choose the appropriate sub-coordinator.
Click “Update User”.
Continue with steps 1-4 until all teachers are under the appropriate sub-coordinator.
