Abstract
The existence of social differences in educational achievement as a social fact presents the sociology of education with a challenge to which it has responded with indifferent success. It is argued that contemporary explanations that dismiss the existence and relevance of differences in cognitive performance arising as a consequence of class variation in socialisation are likely to misrepresent the real causes of inequality/difference. The substantive discussion, organised around six questions dealing with the explanatory capacity of this concept, suggests that a satisfactory theory of inequality of educational opportunity will need to concern itself with the effects of socialisation on cognition. Some implications for educational practice and policy‐making are briefly noted in conclusion.
