ABSTRACT
Among those who study education systems there has been a general concern with schooling outcomes, which has encouraged a focus on the main classroom and general education. This deflects attention from another important issue, the ways that schools understand differences in pupil performance and identify pupils in terms of that understanding. Concern with this issue encourages a focus on educational psychology and special education, where such understandings are developed overtly and such identifications are made explicitly. The purpose of this paper is to present some of the work in the sociology of special education that bears on this neglected issue. It does so by describing three main themes within the field. These are: cultural understandings of ability and disability, the social processes by which children are identified as disabled, and extra-school influences affecting the development and operation of special education.
