Lessons from London schools for attainment gaps and social mobility

External publication

Successive governments have sought to narrow the achievement gap between pupils from advantaged and disadvantaged backgrounds, as part of wider efforts to improve social mobility. For future policy to be most effective, it is important to learn from successful examples of where the achievement gap has been narrowed. The improvement in London schools over the past decade stands out as an important example of improvement in academic achievement, and most crucially as a narrowing of the achievement gap.

The key question for policymakers interested in narrowing the achievement gap is whether the 'London effect' can be replicated across the rest of the country. In order to answer this question, we must understand, first, when the performance of disadvantaged pupils in London improved and, second, why this might have happened.

In this report, carried out jointly with the Institute of Education, we examine:

  • When London’s secondary schools began to improve, by showing the average Key Stage 4 performance of different areas of the country over time.
  • The extent to which the improvements we see in London and other big cities can be explained by changes in pupil characteristics, such as the composition of pupils and families. We also examine whether improvements at Key Stage 4 can be explained by differences in prior attainment at Key Stage 2.
  • The performance of disadvantaged pupils at Key Stage 2 in English and maths to see if and when, and in what subjects, disadvantaged pupils in London began to improve relative to the rest of the country.
  • Whether improvements at Key Stage 4 are sustained into Key Stage 5 and whether differences in post-16 outcomes are influenced by Key Stage 4 attainment.
  • Why London’s schools might have improved by considering the plausibility of different explanations.
  • The implications for policy and the future outlook for attainment gaps.
