Children who have sensory, cognitive or oromotor deficits, or come from a bilingual-speaking background are currently excluded from the diagnosis of specific language impairment (SLI). Emerging evidence, however, suggests that at least 7% of all children have language learning difficulties, irrespective of other diagnoses or language learning background. The aim of this study was to investigate the language abilities of an adolescent boy with pre-lingual, severe-profound hearing loss who comes from a non-English-speaking background. This student's performance on standardized tests is described and qualitative language analyses examine his impairment. His abilities are compared with that of a matched control. The language difficulty identified could not be attributed to either hearing impairment or non-English-speaking background. The student's data suggest the need to expand the concept of SLI to include children with other impairments and from different language backgrounds in order to provide equity of support services and access to the classroom curriculum.
