This article examines textual traces of the standard language ideology within current education policy in England, focusing on post-2010 reforms which are characterised by a (re)shift towards conservatism, discipline, and standards. Using tools and methods from critical stylistics and the critical discourse analysis of language policy, I interrogate a number of mechanisms which textually reinforce and reproduce the standard language ideology: curriculum documents, assessment instruments, national test materials and guidance for teachers. Whilst previous criticisms of current policy have focused on individual policy mechanisms, in this article I examine these mechanisms as a cluster, showing how they work together as de facto language policy. I show how teachers are presented with a de-historicised and de-politicised version of standardised English which masks the structural power relations that are embedded in language, and how they are constructed as standard language role-models who have a professional duty to reproduce the standard language ideology.
