C-NLD Scoring
Non-verbal learning disorder includes multiple specific symptoms characterized into three specific areas: neuropsychological deficits (deficits with perception, psychomotor coordination, memory, reasoning, and aspects of speech), academic deficits (mathematical reasoning, reading comprehension, and comprehension of written language) and social-emotional/adaptational deficits (social awareness and difficulties in social interactions).
The C-NLD works as a primary screening measure, and referral to a neuropsychologist for further testing is advised if the parent C-NLD report indicates "sometimes" or "often" for over half of the items in each of the three sub-sections.
