Paper 1This first of three papers identified current areas of educational psychologist (EP) scholarship across key publications read by a sample of 13 EPs working in three different models of service delivery in England on the topic of developmental dyslexia (henceforth, dyslexia). Findings imply that the EPs sampled do not access high quality scientific research literature on dyslexia; most of the literature accessed appears to be non-peer reviewed and there is little information to support the development of EP practice for assessment and intervention, understanding the link between literacy failure and mental health, or how all this contributes to a consultation method of service delivery.Paper 2The focus of the empirical paper was to describe and analyse how EPs currently conceptualise dyslexia and delineate what they do with regard to assessment and intervention. Furthermore, it explored how EPs' beliefs about dyslexia, and the wider social context, impact on practice. Findings suggest that dyslexia remains an area of significant confusion and contradiction for the EPs interviewed. Most continue to rely on the British Psychological Society's (BPS, 1999) definition but this appears to add to their confusion rather than clarify their thinking which, in turn, seems to reinforce their beliefs or 'world view' about dyslexia. A very narrow range of actual practice in terms of assessment and intervention was described by the participants.Paper 3The final paper discussed evidence-based practice (EBP), effective dissemination strategies to promote and measure outcomes, and the impact of such research. To conclude, some thought is given to ways in which the current research contributes to EBP and possible media for dissemination.
