Please find below a link to a briefing about 2022 national government attainment data on deaf children in England.

This was updated on 24th May 2023: https://www.ndcs.org.uk/media/8720/ndcs-note-on-attainment-data-2022.pdf

This is DfE data for children where deafness has been identified as the primary special educational need. It will not include deaf children who have not been formally identified as having a special educational need or where deafness is a secondary need (for example, deaf children with complex learning difficulties). The figures should therefore be used and interpreted with caution as they will not include all deaf children. As far as we know though, they remain the best data available in this area and for any benchmarking or comparisons over time.
