Today, I gave a brief presentation – based on our previous stories – on the performance of London schools to the excellent Centre for London. Some slides are a little mysterious without my burbling over the top, but I hope it’s understandable enough.
Since January, schools have been subject to a new inspection regime. Ofsted, the inspectorate, has changed its criteria. Data released today mean there is one question we can consider: is the new inspection regime any tougher or easier than its predecessor?
This is not a straightforward question: weaker schools get inspected more regularly, so the sample is not randomly selected. What we can do, however, is see whether schools are more likely to be promoted or relegated than in previous years.
This, too, is not simple. The Department for Education changed schools’ ID numbers when they became academies,
so I cannot match every new report to the same school’s previous ones so it is a faff to match records, which has taken a bit of tinkering. We have matches for 1,711 schools – both primary and secondary.
Here are the results:
At the moment, groups putting forwards bids to open free schools – new academies opened from scratch – are finding out whether they have been approved for 2013 opening. This is an opportune moment to take a quick look at this programme.
Last week, I explained part of why the “converter academies” programme is so popular: it usually comes with a cash incentive to join in. But free schools have their own funding wrinkle. This one encourages primary free schools to be smaller than other local schools.
Using the DfE’s formula for free school funding, we can work out how much a primary free school would get in revenue (day-to-day) funding, plotted against how big it is, if it were to open at full capacity in the London borough of Camden in 2012-13.
This is the output of a formula: every primary free school gets a £95,000 payment plus a certain amount per child, which varies from borough to borough. In Camden, once you have counted in the pupil premium, SEN (special educational needs) funding and other funding, each extra child brings in, on average, an extra £5,870.
But the structure of the formula – a lump sum plus a roughly flat per-pupil payment – means that the amount you receive on average falls as the school grows. This is because the £95,000 lump sum (which is the same for all boroughs) gets shared between more and more pupils.
