Regulatory drivers of teacher quality and teacher professionalism are increasingly being utilised in Australia and internationally to improve children's outcomes. In the context of a recent national review on teacher registration, this article reports on findings from a small-scale study that investigated three early childhood teachers' perceptions of teacher registration in New South Wales, Australia. The participants rejected discursive truths about the need for and benefits of teacher registration, associating this relatively new mechanism of teacher accountability as a threat to teachers' professional practice and job satisfaction, and to centres' provision of quality early childhood education. The findings problematise a discourse of teacher professionalism made enticing by a vow to bring early childhood teachers in from the margins of the educator sector.
