I was also under the impression that the London Challenge was fab. The London Challenge was established in 2003 to tackle underperformance in London secondary schools and significant secondary school performance improvements seemed to take place. This was sos successful that it was repeated to some degree in other English cities but without the same marked results. More recent research by The Institute of Fiscal Studies suggests otherwise which I was surprised by.
This research suggests this improvement was not from Teach First and the London Challenge but the improvement in primary school results which means that London primary school children go to secondary schools with high prior attainment, which is the biggest determinant in secondary school performance.
Well done to all our primary schools. I’m sorry your huge success has been hidden by inflating the results of other interventions.
