If differences are detected between the current state in Google Classroom and your SIS classroom enrollments, a sync analysis will include a set of recommended actions for review.
The summary tab summarizes the findings of the analysis, prompting for a review of any actions that have been identified. When run in manual mode, before actions can be committed to Classroom, they must be reviewed and staged.
In this summary, 177 classes have no changes identified. This is because the classes exist in both the SIS and in Google Classroom, there were no changes detected in rosters, and no updates to Classroom fields are required.
26 actions require review, broken out into 16 new class invites, and 10 potential class matches.
In this case the job scope / rules include only classes from one school site, so the majority of classes in the source data were excluded from the analysis entirely.
