Len Barton has pioneered the sociological study of education in the areas of disability studies and inclusive education. This paper addresses an argument developed by Len Barton that social exclusion, of which disablism is one element, (1) has many compounding forms of differing exclusions, (2) is not a natural but a socially constructed process, (3) has no single factor that can remove it and (4) is in constant need of conceptual analysis. Our paper aims to address each of these four challenging themes in relation to the contemporary societal position of disabled children, their families and key professionals that work around them, with a specific focus on schools. First, we explore the ways in which disabled childhoods are imbricated with other forms of exclusion. Second, we consider the ways in which "disability", "impairment" and "child" are consistently being reproduced in particular and often contradictory ways by disability discourses. Third, we consider the need to work with numerous forms of educational intervention that address the exclusion of disabled children. Fourth, we conclude with an appeal to develop disability studies in ways that build on the shoulders of (social model) greats--such as Len Barton--whilst being receptive to other transformative perspectives from queer, feminist and postcolonial studies.
