About this list

Schools are listed by their School Chooser Score, highest first. Schools without a score (independent schools and those with too little published data) come after, in alphabetical order. The score compares each school with schools that have a similar mix of pupils, not just with each other, so a school with a lower score in a wealthier area may still have better exam results. How the score works.
