Initial estimates of teacher value-added in English primary schools, British Educational Research Journal, June 2025
This new study explores teacher 'value-added' – the impact teachers have on pupils’ academic progress – in English primary schools. Using internal assessment data from two multi-academy trusts, the researchers found that much of the progress pupils make in reading and maths happens across different teachers, not just within individual classrooms. Interestingly, they found no clear link between teachers and pupil attendance. The paper also highlights the challenges of measuring teacher impact in England and suggests next steps for future research.
