There are manifold benefits of parental involvement in a child's education, but there is evidence of gender imbalances in parental involvement. This article describes research into fathers' involvement with educational psychologists (EPs) working with children undergoing statutory assessment. A content analysis of children's files from one educational psychology service was conducted to assess the level of paternal involvement in EPs' work, and semi-structured interviews with eight fathers were used to identify factors that affected their involvement with EPs' work. Fathers were less involved than mothers, and a number of factors affecting fathers' involvement was identified. The discussion of findings is informed by Community Psychology, Ecosystemic Theory and the Theory of Planned Behaviour, and strategies to promote paternal involvement are identified.
