ABSTRACT The representation and retention in the teaching profession are lower for people from all minority ethnic groups in England. The most significant ethnic disparities were found to occur in the early career stages (Worth et al., 2022). This article draws on critical race theory to investigate how racism, in the form of racial microaggressions, contributes to these disparities. It shares the findings from a small-scale research project on student teachers’ experiences of racial microaggressions while learning to teach and discusses the implications for retention in the profession. It draws on a pilot survey (N = 42) and interview data from 14 pre-service teachers from a variety of ethnic and subject backgrounds to explore participants’ racialised experiences on school placements, as well as university elements of the Initial Teacher Education (ITE) programme in England. The findings suggest that microaggressions were more common on school placements than at universities. There is evidence to suggest that experiences of racial microaggressions may negatively affect minority ethnic student teachers’ thoughts on viability in the teaching profession.
