This seminar explores the process of formal and informal exclusion from the macro, meso and micro level to understand some of the complex interactions between policy, school and individual factors. Government statistics indicate that children and young people with special educational needs are five times more likely to be excluded from secondary schools, and account for just under half of excluded pupils. This seminar will explore the process of formal and informal exclusion from the macro, meso and micro level to understand some of the complex interactions between policy, school and individual factors. The significance of these on the lives of young people will be illustrated with reference to data drawn from the topical life histories of autistic girls. These portray the experience of having ones’ needs continually underestimated or misunderstood coupled with a lack of in-school support.
