As the “tech person” at my school, I’ve seen so many teachers, administrators, registrars side-step their school provided SIS in favour of using a good ol’ spreadsheet. This is a waste of time as it creates two sets of data that needs to be synchronized. The other SIS will recreate features of a spreadsheet, but a school or a teacher will inevitably require a special scenario that the commercial SIS cannot handle.
Stringwood SIS is a student information system that is a spreadsheet. Therefore there is no need to sidestep this SIS because it is based on a full featured spreadsheet. In addition, Stringwood SIS is based on a very familiar Google Apps platform. No need to learn a new system, a new menu structure or even a new interface.
I should mention that this is a real product that I have been developing for the last couple of years. I use it every day.
