Any classes syncing with Google Classroom will not be associated to the school/district account in any way. The data from classes syncing with Google Classroom will now be viewable in School Reporting Mode or use for any data collaboration between staff.
Note: Currently this feature is encouraged for teachers using a free or paid teacher account. School and district accounts should continue using their current method of syncing. If you choose to not import a data file, this feature would allow your staff to get their classes set up quickly and sync nightly.
