One question I get asked a lot is: “You say that Frewmanackshire is a terrible local authority. How do you know? Do you know what we are working with?” etc etc. It is true that schools with radically different intakes cannot be usefully compared. So I thought I would let you in on how I benchmark schools, and supply you with two jolly new maps.
What I do for secondary schools, is run a simple regression – that is to say, I fit a simple line through all the pupils’ school results in the country after asking it to account for the children’s ethnicity, poverty and prior test results. Unlike other models, the regression contains precisely zero information about the schools – only data about the children. Read more
Last week, the FT published an interview with Sir Michael Wilshaw. Lots of interviewees, especially in public policy, are very guarded. Sir Michael is not. This may give his press handlers nightmares, but everyone should welcome it. This is for educationally minded people more than data nerds, but I thought I’d put up some more of his thoughts.
I’ll not publish the whole thing yet (there are a few things we discussed that I intend to return to). So this is still a highlights package. First, a few shorter snippets. It’s very striking how often London Challenge, a policy to improve schools in the capital, came up. Sir Michael, who rose to prominence as a London head teacher, kept praising that policy. For example, speaking about the north, he said:
What is it about those areas like Hull and Grimsby and North Lincolnshire that prevents those youngsters doing well? Some of it is quite honestly a political failure where we’ve known that these areas were failing for a number of years and if local politicians really want to address this, they can put pressure on both schools, local authorities, the department for education to do something about this. We’ve shown through London Challenge what can be done in London. London is certainly… and I’ve been a London teacher all my life. It wasn’t a good place to be in the 70s and 80s and 90s; now it’s one of the top performing parts of the country through London Challenge. Same happened in Manchester. So, why can’t we do that in these areas?
