Teacher registration is increasingly utilised as a governance mechanism to audit teachers' work and drive professional practice. There is limited and mixed empirical evidence, however, as to whether registration drives teaching quality. Our study extends this limited empirical base by critically examining the policy trajectory in Australia to bring early childhood teachers into a uniform system of registration with primary and secondary teachers. Adopting a relatively novel methodology, the study intertwined a critical social policy framing with a national quantitative survey. Results showed that respondents perceived their professional self, followed by their workplace (colleagues and employer) as key influencers of quality practice, and neither agreed nor disagreed that teacher registration was beneficial. Findings problematise the need for, and benefits of, teacher registration. That early childhood teachers' practice and development was most driven by intrinsic motivation and, to a lesser extent, being employed in high-quality, not-for-profit, and preschool settings where other early childhood teachers are employed, suggests that more effective and progressive policy approaches to support quality early childhood education require an addressing of the contexts and conditions in which early childhood teachers work.
