Hi Linda 

Thanks for posting in the Lucidchart Community! You can use groups to divide your team into manageable chunks composed of a higher education teacher who you can assign to be a Group Admin and their students and then use our group-based user management to allot different quantities of licenses to be available to each group.

To learn how to create a group add users to a group and assign a Group Admin please check out the Create and Manage Groups section from our Team Admin Panel: User Management article; and to go over the details of how to manage groups and allocate licenses allotments to groups please read through our Group-based User Management for Enterprise Accounts article. 

Hope this helps!
