Growing concerns about the experience and achievement of Black pupils (especially Black males) underpin calls for more Black people to serve as teacher and lay mentor role models in schools. Calls for increased numbers of Black teacher role models assume firstly, that Black teachers regard themselves as role models and want to perform such a role in school. Secondly, that Black pupils will automatically see Black teachers as role models for Black pupils and make a connection between the behaviour modelled by Black teachers and their own behaviour, aspirations or achievement. Thirdly, that Black teachers are the most appropriate role models for Black pupils. This article draws on empirical data to explore these assumptions and to illustrate the ways in which they are flawed. (Contains 2 notes and 2 tables.)
