In contrast to dyslexia and autism, specific language impairment (SLI) is a neglected condition not only in research, but also in debates about policy and practice. A recent analysis of research publications and grants confirmed this impression, showing that SLI attracted far less research funding and led to fewer publications than many other conditions of comparable frequency and severity. At the end of 2011, the authors decided to take action and formed a group with the name RALLI, standing for "raising awareness of language learning impairments." This group consists of four academics, two of whom trained as speech and language therapists and two as clinical psychologists, together with a practicing speech and language therapist. They decided that what was needed was a campaign to put accessible materials on the internet in a form that would attract attention from the general public. Their aim was not to raise money or to improve provision, but simply to improve the recognition of children's language impairments. In this article, the authors describe the background and rationale of the internet campaign to raise awareness of language learning impairments (RALLI).
