Career Center Users can manage student access to their sites through Student User Roles. Student User Roles allow students access to specific modules of the site. For example, if you as a career center user wanted a student to have access to events and appointments, but not job postings, you could create a Student User Role with exactly that set of permissions.
To create a student user role, navigate to the Manage Users page via your Site Management settings -- select "Student / Alumnus User Roles" -- select "+ Add New User Role".
Select the desired permissions for students who will have this user role.
You can assign a user role to multiple students at once by using the Bulk Student Update tool, or to individual students by editing their account and toggling the User Role field (pictured below).
