The aim of this article is to reclaim social class as a central concern within education, not in the traditional sense as a dimension of educational stratification, but as a powerful and vital aspect of both learner and wider social identities. Drawing on historical and present evidence, a case is made that social inequalities arising from social class have never been adequately addressed within schooling. Recent qualitative research is used to indicate some of the ways in which class is lived in classrooms. The article also raises concerns about the ability of the education system to positively address social class in the classroom when contemporary initial teacher training rarely engages with it as a relevant concern within schooling.
