The present paper examines efforts by government and government agencies in England to prescribe and control the knowledge base of a teaching profession that has, under successive New Labour administrations since 1997, been subjected to "modernisation". A theoretical framework drawn from aspects of the work of Basil Bernstein, and of Rob Moore and Lynn Jones, is drawn upon to examine in some detail one key aspect of this ongoing process of governmental appropriation of professionalism: the specification by the Training and Development Agency for Schools of new "standards" for both initial teacher training and teachers' subsequent career progression. It is argued that although this enterprise represents itself as a species of purely common-sense reform, it is in fact a mode of competency training that is rooted in selective appropriation of elements of post-fordist management theory and a loose form of behaviourist psychology. The capacity of this training discourse to suppress awareness of its own presuppositions and of alternative or competing conceptions of professions and professionalism is explored. (Contains 8 notes.)
