DYSLEXIA - DIAGNOSTIC CRITERIA 

II. DIAGNOSTIC CRITERIA

NOTE: The proper use of these criteria requires specialized clinical training that provides both a body of knowledge and clinical skills.

According to the American Psychiatric Association, the diagnostic criteria for Reading Disorder (Dyslexia) are as follows (DSM-IV, 1994):

Reading achievement, as measured by individually administered standardized tests of reading accuracy or comprehension, is substantially below that expected given the person's chronological age, measured intelligence, and age-appropriate education.

The disturbance in Criterion A significantly interferes with academic achievement or activities of daily living that require reading skills.

If a sensory deficit is present, the reading difficulties are in excess of those usually associated with it (the specific sensory deficit).
