Dr John Jerrim's research on England's ranking on the Programme for International Student Assessment (PISA) table has reframed the debate on school pupils' academic achievement.

Dr John Jerrim at the Institute of Education has influenced how statistical evidence on educational achievement is presented to the British public by government departments and policymakers. His research investigated the claim that England has fallen down the Programme for International Student Assessment (PISA) rankings of school pupils' academic achievement.

Accurate representation of data is fundamental to maintaining both public trust in official statistics and the credibility of quantitative social science research. Dr Jerrim has reframed the debate on school pupils' academic achievement, concluding that England's apparent declining performance on international tests is not a statistically robust finding and that public policy should not be based upon these claims.

Dr Jerrim created a dissemination strategy, including early engagement with key stakeholders and a close working relationship with the Institute of Education communications team, to avoid any potentially hostile response to his work.
