AA. Acquisition and execution of coordinated motor skills is substantially below expected for chronological age and opportunity for skill learning B. Motor skill deficits significantly and persistently interfere with activities of daily living appropriate for chronological age, and with academic/vocational productivity, leisure, and play C. Onset in the early developmental period
BA. Deficits in intellectual functions (reasoning, problem-solving, planning, abstract thinking, judgement, academic learning, experiential learning) confirmed by clinical assessment and standardised testing B. Deficits in adaptive functioning in ≥1 of: conceptual, social, or practical domains — resulting in failure to meet developmental/sociocultural standards for personal independence/social responsibility C. Onset of intellectual and adaptive deficits during the developmental period

Differential flags
ANeurological disorder with motor impairment (cerebral palsy, muscular dystrophy, hereditary neuropathy - neurological examination and investigations); Intellectual disability (motor difficulties proportional to global impairment); ASD (motor difficulties but social communication deficits primary)
BASD (social deficits; RRBs; may coexist - code both when criteria independently met); Specific learning disorder (domain-specific; overall intellectual function preserved); Communication disorder (language-specific; not global intellectual impairment)
