Specific Learning Disability — ICD-11 Developmental learning disorder (6A03) — is a persistent, school-age difficulty in reading, written expression or mathematics, substantially below age expectation and not due to intellectual disability, sensory loss or inadequate instruction. 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.

*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.*

## In short
Specific 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.

## ICD-11 features and the early-childhood picture
ICD-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.

## When to refer
Formal 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.

## The Pinnacle way
AbilityScore® is part of Pinnacle’s developmental assessment. Diagnosis, where needed, requires an appropriately qualified healthcare professional — never from an app or checklist. We map precursor skills and route families to the right support. Explore [Specific Learning Disability](/specific-learning-disability), our [special education and remedial therapy](/special-education-therapy), and [how the AbilityScore® is calculated](/ask/what-is-the-abilityscore-and-how-is-it-calculated).

## Trusted sources
WHO ICD-11 (6A03 Developmental learning disorder); CDC Learn the Signs. Act Early; Indian Academy of Pediatrics; American Academy of Pediatrics (HealthyChildren.org).

This is general information, not a diagnosis — individual assessment and diagnosis require an appropriately qualified healthcare professional.
