The Effective Pre-School and Primary Education 3-11 (EPPE 3-11) project investigates the impact of pre- school, primary school and family on a range of outcomes for a national sample of approximately 2,800 children in England between the ages of 3 and 11 years. This Research Brief presents findings on pupils' Self-perceptions (' Enjoyment of school', 'Anxiety and Isolation', 'Academic self-image' and 'Behavioural self-image' ) and their views of different features of primary school (' Teachers' support for pupils' learning', 'Headteacher qualities' and 'Positive social environment' ) in Year 5. The analyses involved two steps: first, differences in pupils' Self-perceptions and Views of primary school measured at Year 5 were explored, in relation to child, family and Home Learning Environment (HLE) characteristics. Second, the relationships between pupils' Self-perceptions and their Views of primary school and educational outcomes and progress, both cognitive (Reading and Mathematics) and social/behavioural ('Self-regulation', 'Hyperactivity', 'Pro-social' and 'Anti-social' behaviour) were investigated. The analyses also explored pupils' Self-perceptions measured at a younger age (Year 2) and how they relate to children's later cognitive and social/behavioural outcomes in Year 5 and progress from Year 1 to Year 5.
