This investigation provides a basis for considering the role of corrective and transformative critiques in producing knowledge through testing teaching for reframing teacher education in response to, and as an expression of, the globalisation of English. This knowledge-producing approach to critique begins with a literature review of prior testing models of content and language integrated learning through English medium instruction (EMI) programmes. Through adopting the practice of critique as a knowledge-producing venture, this study offers a model of EMI testing that can contribute to improvements in the organisation of professional learning and change, as well as certification procedures.
