This paper examines the outcomes of a disability awareness programme aimed at rethinking concepts of special educational needs and disability (SEND) with children aged 8–9 years old. Designed specifically for this research study, the work was undertaken in a mainstream primary classroom in England. Although research has been undertaken in this area, it is limited and often focused on children's friendships. Drawing upon a disability studies in education lens, the study contributes to the literature through its use of interactive methods to elicit and deconstruct children's thinking. The findings suggest that many children continue to hold deficit perceptions about SEND, rooted in medical model perspectives. However, carefully designed programmes which enable children to consider first‐person experiences, and encourage the deconstruction of ableist discourses, can promote more flexible understanding and progressive attitudes towards SEND in childhood.
