Mathematical ability, as measured by individually administered standardized tests, is substantially below that expected given the person’s chronological age, measured intelligence, and age-appropriate education.
The disturbance significantly interferes with academic achievement or activities of daily living that require mathematical ability.
If a sensory deficit is present, the difficulties in mathematical ability are in excess of those usually associated with it.
This disorder has been reclassified and altered in the updated 2013 DSM-5 (e.g., now combined with other disorders associated with academic deficits); the old DSM-IV criteria above remain here for historical/informational purposes only. See updated DSM-5 specific learning disorder criteria.
