Research into dyslexia has focused exclusively on children and adults with normal hearing. However, many deaf children at school in the UK also have reading difficulties. A key challenge when trying to diagnose dyslexia in a deaf child is the lack of suitable tests. There is also little information about typical reading profiles of deaf children. How do you decide if a deaf child has dyslexia if you do not know what is typical for their age group? Research is beginning to address this area. Using deaf-friendly testing methods, a research team at City University London is collecting scores on reading and dyslexia-sensitive tests from a large sample of children born with severe-profound deafness.
