This project follows a survey into the role of UK educational psychologists (EPs) in delivering therapeutic interventions to children and young people. Four educational psychology services (EPSs) that identified themselves as providing effective therapeutic practice were selected on the basis of their qualitative responses to the survey. Site visits included analysis of service documentation, an interview with the Principal Educational Psychologist (PEP) and focus groups with EPs and with stakeholders, multi-agency partners and commissioners of EPSs. Thematic analysis yielded a number of key themes. Those relating to how the service context can support the delivery of therapeutic interventions included: "contracting and promoting"; "leadership"; "opportunities to practice"; "supervision"; "time and resources"; and "training".
