At this time we do not pull in or sync class rosters from any SIS (Student Information System) or 3rd party syncing system such as Clever or ClassLink.
You must build rosters inside Flex. You can do this via CSV file uploads or directly within flex by searching for students individually. It is also possible for schools to send or upload CSV roster files to the SFTP server and link them to a Flex roster so that whenever an updated file is sent/uploaded, the roster will be updated. (A Flex "Admin" would need to set this up and coordinate assistance from the school's technical team, as needed.)
Please reference our additional training material on “Rosters” which can be found in the HELP menu within the Flex system.
