One promise of open data is its ability to inform citizens and consumers about the quality of local services. At the Gov 2.0 Summit yesterday the US Department of Health and Human Resources announced it was releasing data on hospitals, nursing homes and clinics in the hopes that developers will create applications that show citizens and consumers how their local hospitals stacks up against others. In short, how good, or even how safe, is their local hospital?

In Canada we already have some experience with this type of measuring. The Fraser Institute publishes an annual report card of schools performance in Alberta, BC, Ontario and Washington. (For those unfamiliar with the Fraser Institute it is a right-wing think tank based in Vancouver with - shall we say - dubious research credentials but strong ideological and fundraising goals.

Perhaps unsurprisingly, private schools do rather well in the Fraser Institute's report card. Indeed it would appear (and I may be off by one here) that the t0p 18 schools on the list are all private. This does support a narrative that private schools are inherently better than state run schools that would be consistent with the Fraser Institute's outlook. But, of course, that would be a difficult conclusion to sustain. Private schools tend to be populated with kids from wealthy families with better educated parents and have been given a blessed head start in life. Also, and not noted in the report card, is that many private schools are comfortable turfing out under-performing or unruly students. This means that the "delayed advancement rate," one critical metric of a schools performance, is dramatically less impacted than a public school that cannot as easily send students packing.
