We recently rolled out the first exporting abilities. You are able to export whole class grades for any assignment and/or export grades for individual students who are not GC enabled.
To export grades for an assignment, start from your teacher dashboard and click "View Class Assignments" and then open an assignment. From the assignment page, you'll see a button to "export grades" to the left of the large "Create Assignment" button. This will allow you to download a CSV file of the data!
Alternatively, you can go to a student's individual profile, and export grades for all of their assignments.
Students who have google permissions enabled for Garbanzo do not yet have the export grade feature, but we are working on it!
