The latest school performance tables signal a change in the way schools will be judged in future.

Figures published this month from the Department for Education show that around 10% of secondary schools opted for the new performance measure – Progress 8 – a year early.

Progress 8 looks at the progress pupils make between Key Stage 2 tests taken at the end of primary school and their performance across 8 specified subjects at the end of secondary school. Schools are given a score based on how their pupils have progressed compared to the national average.

Progress 8 will become the main measurement for all secondary schools in the 2016 performance tables.

This will replace the measure of 5 or more GCSEs at A* - C which was used for the last time in this month’s tables.
