Open (education) data: Supply, demand, and something in between screenshot screenshot is a fascinating new website that presents Tanzanian Form 4 exam results in some very interesting ways. It is potentially very useful to anyone with an interest in education in Tanzania – students, parents, teachers, local government, politicians, journalists and analysts.

Would you like to know how well your secondary school (or your child’s school) is performing? Would you like to compare exam results across different regions of Tanzania, to follow trends over time, or to see the effect of the adjustments made to 2012 exam results? If so, this site is for you. Launched (in beta) earlier this week, it has been put together by a group of young Tanzanian software developers, led by Arnold Minde, with some support from Twaweza.

Let’s have a brief look at some of what the site can do.

The site uses data that the Tanzanian government has, for several years now, been publishing on Form Four exam results. This started long before the current fashion for open government and open data, and well before Tanzania signed up to the Open Government Partnership (OGP). It wasn’t published particularly as an “open data” initiative, but simply as a way for individual students to access their results. Arnold and his team therefore had to do a lot of work downloading and processing the data to make it usable, even before they started finding interesting ways of presenting the data.

I find the site very interesting for a number of reasons, that go well beyond the contents. 

First, it was developed by young Tanzanian developers on their own initiative – they came to Twaweza rather than Twaweza going looking for them. And they came primarily for advice, rather than for funding.

Second, by coincidence, has been launched not long after the National Examinations Council of Tanzania (NECTA) released it’s own Education Dashboard, presenting much the same data in some very different ways, under the heading of the Big Results Now initiative. And the Open Institute in Kenya has also been working on something similar. Some might call that duplication, I call it healthy competition. The most useful site will attract the most users.

Third, even though uses data that wasn’t released under an “open” heading, it shows clearly what is possible when government datasets are made public. It’s a real-life example of the “let a thousand flowers bloom” theory of open data. Publish, publish, then publish some more, said Tim Berners-Lee, and someone you don’t know will find unexpected and interesting things to do with the data. It doesn’t always work, but in this case it has.

Arnold is an infomediary – an ugly word, but a useful one – meaning someone who can turn the raw materials of data into something useful to “ordinary” wananchi. There’s a supply, there’s a demand (we assume), and now there’s something in between.

I hope it gets the traffic it deserves.
