This page shows the secondary schools in England that have had the biggest sustained improvement in their results over the previous four years.
The columns show the proportion of students getting at least five good GCSEs or equivalent vocational qualifications each year, including English and maths GCSEs, and the overall increase.
The "top 100" list is compiled by the Department for Education and Skills.
The head of the school that came top, Jo Mullis, said half the trick was knowing which of the department's initiatives to "chuck in the bin".
The key to inclusion in the table is consistency - a school's results have to have improved each year. Other schools might have had a bigger rise across the four years, but with a dip along the way.
