The use of targeted additional funding for school-age education, intended to improve student attainment, is a widespread phenomenon internationally. It is slightly rarer that the funding is used to improve attainment specifically for the most disadvantaged studentsoften via trying to attract teachers to poorer areas, or encouraging families to send their children to school. It is even rarer that funding is used to try and reduce the attainment gap between economically disadvantaged students and their peers, and almost unheard for the funding to be intended to change the nature of school intakes by making disadvantaged students more attractive to schools. These last two were the objectives set for Pupil Premium funding to schools in England.The funding started in 2011, for all state-funded schools at the same time, so there is no easy counterfactual to help assess how effective it has been. The funding is a considerable investment every year and it is therefore important to know whether it works as intended. This paper presents a time series analysis of all students at secondary school in England from 2006, well before the funding started, until 2019, the most recent year for which there are attainment figures. It overcomes concerns that the official attainment gap between students labelled disadvantaged and the rest is sensitive| 447
