The work of teachers is public work: it takes place in the public domain and should, in principle, be orientated towards the public good rather than serve private interests. This not just suggests an intrinsic connection between teaching and democracy, but also makes a particular case for teaching as a profession. In my presentation I will explore the ways in which teacher professionalism has changed over the past decades, with a particular focus on the democratic dimension of teacher professionalism. I will focus on [1] the relationship between teachers and students; [b] the question of accountability; and [3] the role of knowledge, values, scholarship and research. With regard to each I will suggest that what may look like a democratisation of the teaching profession actually has turned into its opposite, which has much to do with technicist conceptions of education and with the role of measurement and data. I will conclude with some suggestions about the push backs that may be needed, and what this means for teachersβ agency.
