This article reports on a study of 267 primary children (Year 2 and 6) in five schools in South and Mid Wales. It examines their use of information and communications technology (ICT) both in school and at home using a combination of interview and questionnaire data. These data reveal that although the vast majority of children are making some use of computers in school, patterns of sustained and varied engagement with ICT are rare; with educational use of computers curtailed by a variety of classroom factors. Moreover, although many children could be considered to be sophisticated and knowledgeable consumers of ICT, their outside-of-school access to technology is varied. The findings raise questions about the nature of ICT use in primary classrooms and the need to ensure meaningful and regular access to technology in school for all children.
