The report will be of interest to teachers and headteachers, non-maintained setting practitioners and leaders, and officers in local authorities, regional consortia, and the Welsh Government. It will also be of interest to those working in initial teacher education. The report’s findings will help settings and schools planning for the Languages, Literacy and Communication area of learning and experience in A Curriculum for Wales (Welsh Government, 2020b). The report provides short descriptions of effective practice (‘vignettes’) to illustrate how providers develop learners’ skills and knowledge in listening, speaking, reading and writing. We elaborate upon these examples of successful practice in case studies published to accompany this report. These supplementary materials also include prompts to support professional learning activities.
