Pupil Book Study is a window into the 'lived experience' of pupils, as opposed to just the observed experience. It is also a mirror in which to reflect professional practice and identify what helps learning, and what hinders it by outlining clear and coherent structures in which to talk with pupils and look at their books. Pupil Book Study gives headteachers, senior and middle leaders a systematic toolkit to evaluate the impact of the curriculum through studying teaching and learning. Infused with cognitive science research and evidence-informed practice, it offers schools the architecture for excellence; helping remove the risk of making assumptions. Pupil Book Study is a guide for schools that offers 7 specific and fully exemplified areas to focus quality assurance systems. The keystone between teaching, learning and the curriculum, Pupil Book Study offers schools the tools to explain why things are as they are and presents solutions to the areas that limit or hinder progress. Schools report that Pupil Book Study has been some of the most powerful and impactful work they have ever undertaken, resulting in positive change. In November 2020, Pupil Book Study was shared with the Deputy Director, Senior HMI and Policy makers at Ofsted.
