Question to the Department for Education:
To ask the Secretary of State for Education, which 20 secondary schools have had the biggest improvement in GCSE results over the last 15 years.
There is not a consistent metric to measure school performance at Key Stage 4 over this time period. However, the data showing the performance of schools in each of the last 15 years as measured at the time is available at the download data page of the “Compare school and college” website[1].
