An exploratory survey of Assistants in Scottish educational psychology services (EPSs) was undertaken, guided by four questions: Who are Assistants? Why are they employed/not employed? What do Assistants do? How are Assistants supported and supervised? Twenty-one Assistants and 15 managers were interviewed. It was found that Assistants worked under seven job titles; all were committed to becoming educational psychologists (EPs). Recruitment issues and improving EPS research capacity were drivers for employment. The Assistants' roles were largely research based; however a majority worked directly with young people. Induction and supervision were valued but not consistent. Further discussion includes issues of competence and remit, and the relationship of Assistant and professional role. (Contains 15 tables.)
