All educational environments have to submit a certain amount of data relating to performance. This may be exam results, progress trackers and other records which will give the Department of Educations an over view of how they are performing and what needs to be done to make improvements. League tables will give you an overview of the levels the students attending a school are at, but these results may be selective. Higher achieving schools for example may only accept 75% of admissions that they have, selecting the high achieving students. This means that their levels will often be higher than the national average due to the high level they started at.
A mid achieving school may be performing just as well but have a wider range of student ability, meaning their overall score may be lower.
League tables should only ever be used in addition to other information about the school such as Ofsted reports, when making a decision on whether that school is the right place for your child to go.
