Andrew Truby founded the Mastery English programme at St Thomas of Canterbury School in Sheffield to address the need for a high-quality English curriculum for primary schools based around high-quality texts (see  ). This was developed with Learning Unlimited Teaching School Alliance, and building on its success, the DfE approved a Strategic School Improvement Fund project to implement the Mastery English programme in 24 primary schools across the region from 2017 to 2019.  Andrew will talk about the structure of this English curriculum model, the priorities within it and some of the challenges that the development team have encountered.
