This collaborative action research project involves two educational psychologists (EPs) working with teachers from four primary schools to develop the use of solution-focused approaches. The project illustrates a way in which EPs might make a distinctive contribution to improving outcomes for children and young people. Realist interviews were used to identify mechanisms responsible for encouraging change in practice and many of these can be linked to action research or solution-focused approaches. The project will be funded for two years and this report is based on the first year. Progress has been encouraging and findings suggest that solution-focused action research is a successful model for introducing a new initiative. (Contains 2 tables.)
