Thanks both. Yes, there needs to be clear caveats on the data. However parents often find it a useful (in fact the only) indicator of their chances of getting a place at particular schools, and so the information needs to be available to them (along with numbers of places allocated on faith grounds etc in previous years). If nothing else, it enables trends to be analysed.
Of course as soon as you publish that sort of information to some parents (the ones who are savvy enough to ask) a moral duty surely arises for all parents to be given the same information, and for its relative usefulness to be explained. I assume that's why so many LAs do routinely publish it, even when it's not statutory.
The problem is that certain commercial providers are mining the data, repackaging it and reselling it, without all the necessary the caveats. For example it is being used by property portals, who are using it in a way that confuses the housing market. This sort of use is only going to increase and I think LAs need to be more aware of how their data is being used.
I would like to see all LAs publishing the cut-off distance data in a standard format, with a standard caveat, so that parents know exactly where commercially packaged information is sourced from and what it means. Presumably that standardisation will only happen if it becomes statutory. (And I would argue for the September 1st cut-off data to be published alongside the National Offer Day cut-off data, so that parents can make sense of waiting list movement in their areas).
Is there an LGA forum, or equivalent, that centralises discussion on this sort of issue? (My own interest in it is as a parent, a school governor and a home owner).
