Dyslexia is not a ‘category’— it exists on a continuum. Even if it is difficult to be precise about the criteria for defining dyslexia, there are strong theoretical and moral grounds to use the label ‘dyslexia’ to refer to people with severe and persistent reading difficulties. Moreover, ‘naming it’ dyslexia is justified on the grounds of a large body of empirical evidence. ‘The three Cs: caveats, comorbidities, and compensation’ are framed within the Rose Review of dyslexia, an independent study published in 2009, which drew on the best evidence and practice surrounding the nature and remediation of dyslexia.
