Registered files of the Welsh Department of the Board of Education and its successors mainly relating to individual elementary, primary and secondary schools in Wales.
Some files relate to policy matters including the introduction of separate primary and secondary schools in Wales following the 1944 Education Act, the distribution of teachers especially in rural areas with a low population, language policy in schools and the development of teaching through the medium of Welsh, and the effects of the decisions to close many small rural schools, particularly those in Welsh speaking areas.
