Tracking students progress through gradebooks online

Hi all,

My name is Ray and I'm current working on a side project to add value to gradebooks by giving them a host of powerful analytics/metrics.

I have created http://gradebooker.com/demo/home.html as a demo website to try and get some feedback from teachers on what metrics would be of benefit to them.

I've a couple of ideas such as -

- Notifying the teacher when a student does poorly on a test (in compairison to their previous results, so they it is not missed)

- Showing the whole years test results for the class average and individual pupils (would be great for parents evenings) 

- and a whole bunch of other metrics that are already on the demo site.

If you can think of any useful metrics let me know and I shall include them in the service.

Kind regards,

Ray
