It is not diagnosed in early childhood; only precursor skills (phonological awareness, number sense) can be monitored, with formal assessment meaningful around 6–8 years.","answer_md":"*A child who reads, writes or calculates well below expectation — despite adequate instruction and intact senses — is signalling something specific, not a lack of effort.*\n\n## In short\nSpecific Learning Disability — classified in ICD-11 as **Developmental learning disorder (6A03)** — is a persistent difficulty acquiring and applying academic skills in **reading, written expression, or mathematics** that falls substantially below age-expected levels, is not attributable to intellectual disability, sensory impairment, neurological disorder, inadequate instruction or psychosocial adversity, and is not better explained by another condition. It emerges in the school-age years; before formal academic demands it can only be anticipated through precursor skills, not diagnosed.\n\n## ICD-11 features and the early-childhood picture\nICD-11 specifies the disorder begins **during the school years**, requires skills *markedly* below expectation for chronological age, and persists despite targeted intervention. It is sub-typed by impairment in reading, written expression or mathematics. Crucially, **6A03 is not diagnosed in early childhood** — pre-academic skills are still emerging. What is observable instead are *precursors*: delayed phonological awareness, difficulty with rhyme and letter–sound mapping, weak number sense, persistent letter reversals beyond age-typical windows, and disproportionate effort for emerging literacy or numeracy. These warrant monitoring, not a label, and are best tracked alongside language and attention development.\n\n## When to refer\nFormal assessment becomes meaningful around **6–8 years**, once structured instruction has been provided and a gap persists. Earlier referral is appropriate when language delay, attention concerns or family history co-occur — to support, not to diagnose prematurely.\n\n## The Pinnacle way\nAbilityScore® is part of Pinnacle’s developmental assessment.
