Blackboard Learn (previously the Blackboard Learning Management System), is a virtual learning environment and course management system developed by Blackboard Inc.
Roles determine what a user can and cannot do within Blackboard Learn. Administrators use roles to group privileges into sets that can be assigned to user accounts. Every user associated with a role has all of the privileges included in the role. When a user account is assigned multiple roles, the user receives all of the privileges included in all of the roles. As an example, consider this scenario. A role is assigned to a user account that does not include access to the course Control Panel.
