Security aspect is well taken care of with KOAN’s User Role feature. It allows you to define different roles and assign specific access rights to the roles. This ensures that appropriate access rights are assigned to the users at different levels of hierarchy.
With student Groups access rights, can be defined at student level as well. Using ‘Group Codes’ you can decide which group pf students get access to which group. You can view the user membership details and control who should be active or de-active and who needs to be removed from a group.
