In this article, the author argues that there are so many different understandings and conceptualizations about what dyslexia is, or is not, that the term has become almost meaningless. The questioning of the value of the dyslexia concept turned into media headlines in the UK. The author accounts three key questions surrounding the debate about dyslexia in children: (1) The question of "conceptualization"--Is the term meaningful in differentiating between children with literacy difficulties? In other words, can one locate individuals into clear dyslexic/non-dyslexic groups?; (2) The question of "teaching"--To what extent does a diagnosis of dyslexia guide the educator in devising appropriate forms of intervention?; and (3) The question of "resourcing"--To what extent should a diagnosis result in the provision of additional help? The author points out that the current state of knowledge suggests that all youngsters with reading difficulties should be provided with structured intervention programs and one must query whether the amount of energy devoted to diagnosing the condition is a sound use of time and resources.
