This paper explores issues of teacher professionalism. The focus is on the competition, control and standardisation that tend to be associated with ‘entrepreneurial’ professionalism on the one hand, and the autonomy, care and criticality that tend to be associated with ‘traditional’ professionalism, on the other. The paper presents a series of descriptive observations of classroom and school practice and segments of interview data gathered from 11 administrative and teaching staff at a primary school in England. These data illustrate how forms of entrepreneurial and traditional professionalism are operating in the school’s attempts to support its disadvantaged students. Such illustration highlights the tensions and complexity associated with the enactment of both forms of professionalism but, ultimately, the ways in which the current sociality of performativity engulfing schools is relegating traditional versions of professionalism to the margins.
