The Better Communication Research Programme (BCRP) was commissioned as part of the Better Communication Action Plan1 , the government’s response to the Bercow review of services for children and young people with speech, language and communication needs2 . This had recommended a programme of research ‘to enhance the evidence base and inform delivery of better outcomes for children and young people’ (p.50). This is one of 10 publications reporting the results from individual BCRP projects. These contribute to a series of four thematic reports and the main report on the BCRP overall in which we integrate findings and present implications for practice, research and policy from the BCRP as a whole (see Appendix 1 for full details3 ). In order to understand the evidence base of interventions for children and young people with speech, language and communication difficulties, we first have to know what interventions are being used in practice. There are systematic reviews of the research literature which analyse and synthesise the results of studies of the effectiveness of interventions but to date, there has been no review of the interventions currently in use from which to investigate how far current practice is underpinned by research evidence. This project was designed to do that for key interventions that are identified in this project4 . Research questions for the project were: What is the range of interventions being used in current practice? What interventions are used with children and young people from differing age groups, settings and with differing special educational needs? What rationales and explanations do practitioners provide for the selection of different interventions? What outcomes are targeted with these different interventions?
