The Education Inspection Framework is the most researched and piloted framework in the organisation’s history. Ofsted has taken over 25 years of it’s inspection experience and evaluated the existing literature on pupil behaviour and attitudes in schools. This, alongside two phases of research on behaviour significantly strengthens Ofsted’s inspection practice on behaviour. Challenges remain. Data indicators such as exclusion statistics rarely tell the whole story. Matthew will share how the inspectorate has used research to create a framework that captures the most important aspects of behaviour and attitudes and discuss the work that Ofsted are currently doing to further strengthen understanding of behaviour in schools.
