Yesterday I wrote “Why put assessment in the Cloud?” about the project last year for students in New South Wales in Australia to complete the statutory Science examinations online - replacing a paper-based system that had been used for years. As well as the time-saving and paper-saving, one of the other significant benefits was the ability to track activity on the test in real-time - how many schools were logged on, how many students etc.
At the time it was pretty exciting - Janison, who’d created the ESSA testing programme with NSW DEC, had created a Windows Phone application, so that anybody could watch the data in real time wherever they were. I was down in Melbourne on the first test day, and it was great to be able to show people live information - “Look, there are now 15,000 students logged in!”
The only downside to the live metrics was that they were just that - live - so by the end of the week the charts were gone.
But Janison have been even cleverer (is that a word?) by creating a website where you can see a snapshot of the day on 22nd November 2011. You can browse it just like we were able to in real-time during the test, and see exactly the same metrics.

There are all kinds of interesting stats. I’ve kept some of the screenshots I took on the 22nd, to give you an idea of the live service. And the stats come from all of the service users, across public and private schools:
One of the surprises for me was that the minimum screen resolution was 1024x768, with 80% having a horizontal resolution of 1280+ pixels (not shown below, but you can see it on the site linked above)
This is a bit geeky - in essence, it shows how many virtual servers Janison deployed to run the testing. And it makes the point - This is why you use the Cloud - because you can just activate 200 servers in the Windows Azure cloud at 5 o’clock in the morning before the test, and then switch them back off afterwards. And only pay for what you use. That’s the beauty of using the Cloud for assessment - you only pay for what you use, and don’t need to build a dedicated server farm full of hardware to run a test.
