Race, history and visibility have a great deal to do with how disability operated socially and educationally in the Chicago public high school art classroom where I taught for ten years. I am severely near-sighted, and I am also white, educated and often, but not consistently, able to pass for non-disabled. A large number of my students were identified as having learning, emotional and behavioural disabilities, diagnoses which were certainly conditioned by the institution, but diagnoses which perhaps also underrepresented the amount of socially and historically occasioned impairment or debility that existed in the low-income majority-Black community served by my school. In this article I reflect on the overlapping social performances that occurred in terms of 'disability passing', a state that can characterise both hidden and exaggerated or invented impairments. My reflections examine my own individual experience in contrast to the long-term experience of the African diaspora in and beyond the USA, in order to think about other ways to parse the complex factors determining how disability plays out in educational environments.
