The Department’s progress measures, particularly Progress 8, aim to capture the progress that pupils make from the end of Key Stage 2 to the end of Key Stage 4. They are a type of value added measure, which means that pupils’ results are compared to the actual achievements of other pupils nationally with similar prior attainment.
As pupils at independent schools are not required to take end of Key Stage 2 tests, we are unable to include independent pupils in the calculation of Progress 8 scores. We do publish other attainment headline measures on independent schools. The Education (Independent School Standards) Regulations 2014 require that independent schools enable pupils to make good progress according to their ability, and this is checked during inspections of all independent schools.
