This paper draws on recent work by John Clarke and Janet Newman and their colleagues to analyse a relatively coherent governmental project, spanning the decades of Conservative and New Labour government in England since 1979, that has sought to render teachers increasingly subservient to the state and agencies of the state. Under New Labour this has involved discourse and policies aimed at transforming teaching into a "modernised profession". It is suggested that this appropriation of both the concept and substance of professionalism involves an attempt to silence debate about competing conceptions of what it might be to be a professional or to act professionally. The overall process is thus arguably one of de-professionalisation in the guise of re-professionalisation.
