For the past two years, I've conducted an annual survey of OIA performance, requesting Ministers' and Departments' internal OIA data and crunching the numbers to find out who answers on time and who does not. The 2011 financial year has just ended, so its time for another round. Last night I emailed 29 Ministers and 28 departments; now I get to spend the next month alternatively waiting and number crunching. Hopefully this year I'll even remember to post the results.
Of course, this isn't something I should have to do. In the UK, for example, departments are required to proactively publish this information. In Canada, the Information Commissioner collects and analyses the data. Nothing is stopping the government from doing that here, and I'm surprised that they don't.
