This page shows schools in this area ranked on the basis of their "value added" measures from Key Stage 2 to Key Stage 4.
The measure compares pupils' exam performances with the middle performance of other pupils nationally who had similar prior attainment.
It is based around 1000. The top 5% had a score of 1057.9 and above.
The ranking needs treating with care. Official statisticians say small differences may not be significant and the significance varies with the number of pupils involved.
Smaller schools with fewer than 30 pupils taking the exams are not ranked.
