Currently, there is no option to transfer unfinished/unstarted activities with students when they switch classes. The student has already taken the diagnostic and already been assigned lessons based on their results. Switching periods does not suddenly mean they've acquired those skills. Taking the diagnostic again is frustrating for students and teachers alike. Apparently, there are some people who have a different opinion, but this is a simple fix on Quill's end. They can just give the option to teachers to make that choice as they transition students from one class to another. I hope to see an update to this soon.
