When a student has a future start date for a class and a Grade Book District Mass Sync is run, the student will appear in that teacher's gradebook, regardless of the start date. This may be confusing for teachers as they do not expect to see that student yet. This has been escalated to Edupoint for a fix, however there is not an estimated date for a fix yet.
Edupoint has fixed the issue in which the Grade Book was dropping students with a future leave date in a class. A student will now not be removed from a teacher's grade book if the leave date is in the future.
