SchoolMate allows schools to create and send surveys to students, parents and teacher so that they can gather feedback about the school and improve the quality of what it offers.
If there is a survey for you to complete, you will see it on the Main Page when you log in. It might look something like this:
When you complete and send the survey the school does not know what individuals wrote. All the replies are combined and given to the school as overall results, so it is anonymous.
The Survey Menu item just shows which surveys you have filled in, not what the content was.
