This article draws upon data from semi-structured interviews conducted with black mixed-race males in the UK and the US, to argue that a revival of the black supplementary school movement could play an important role in the education of black mixed-race males. The article contends that a strong identification with blackness, and a concomitant rejection of the values of mainstream schooling, make black supplementary education a viable intervention for raising the attainment and improving the experiences of black mixed-race males. Whilst blackness was important to participants' understandings of their lived experiences, this did not engender a disregard for their mixedness. Supplementary schools must therefore find ways of recognising black mixedness within their practice.
