This thematic report is written in response to a request for advice from the Minster for Education and the Welsh Language in his remit letter to Estyn for 2022-23. The report describes how schools are developing pupils’ English reading skills across the curriculum in Year 6 in primary schools, and in Years 7, 8 and 9 in secondary schools or from the age of 10-14 years in all-age schools. It considers how well pupils’ reading skills are developing, their attitudes to reading, and the extent to which schools are developing a ‘reading culture’.
