Find out how progress 8 is calculated, including which qualifications count towards it and how the calculations differ for pupils with missing or incomplete data. Get to grips with confidence intervals, and use the DfE's tool to work out your school's score.

This article refers to the DfE guidance on secondary accountability measures.

What is progress 8?

Progress 8 is one of the headline performance measures reported for secondary schools. It compares how much progress a pupil makes between the end of primary and the end of Key Stage (KS) 4, compared with pupils who started at a similar level at KS2. It tracks this across 8 subjects.

A progress 8 score is the difference between a pupils' actual attainment score across the 8 subjects and the average attainment score of pupils with similar prior attainment.

How are pupils’ progress 8 scores calculated? 

Each pupil’s average score at KS4 across 8 subjects (their ‘attainment 8’ score) is measured against the national average attainment 8 score of pupils who were at the same ‘fine level’ at the end of KS2 (i.e. who left KS2 at the same basic level, as determined by test marks).
