Inclusive Learning: the Report of the Committee of Enquiry into the postschool education of those with learning difficulties and/or disabilities,in England, 1996

ABSTRACT

The Report, Inclusive Learning (1996), is the result of a three‐year enquiry into the educational needs of and provision for adults with disabilities and/or learning difficulties in England. It arose from the requirement of an Act of Parliament, in 1992, that the new national funding council for further education should ‘have regard’ for such students in all its work of funding, development and evaluation. The Committee commissioned some fundamental research into the nature and extent of provision, the actual and potential demand for further education and the current requirements of law, and also reviewed existing academic research (chiefly in English‐speaking countries). It took extensive evidence in many modes and, in particular, created a series of workshops in which the students and their advocates could speak for themselves. The outcome was the main Report and summary, together with six supplementary publications. The core of the Report is the notion of ‘inclusive learning’, which places the responsibility for providing appropriate education with the teachers, the managers and the system (ultimately, with society), rather than problematizing the student as one with a deficit. A good education system is not merely about offering access to what is available, but also the making of what needs to be available accessible: the moulding of opportunity. Thus the Report concentrates on a theory of learning and its educational consequences. It represents another step towards embracing students with learning difficulties and/or disabilities unequivocally within the general approach to learning appropriate for all students. This article summarizes the main lines of analysis and argument in the Report and its framework of recommendations to the Further Education Funding Council, teachers, managers, voluntary organizations and to the government.
