ICHI complements the ICD-11 diagnosis and ICF functioning profile.","answer_md":"*A young child who struggles with number sense is signalling where to begin — and ICHI gives us the shared vocabulary to map intervention to need.*\n\n## In short\nThe WHO **International Classification of Health Interventions (ICHI)** does not assign a single code to dyscalculia (ICD-11 **6A03.2**, developmental learning disorder with impairment in mathematics). Instead, it describes the *interventions* delivered around it — assessment of cognitive and academic functioning, targeted training in number and calculation skills, and education and counselling for the child, family and school. ICHI complements the ICD-11 diagnosis and the ICF functioning profile; together they describe what the child has, how it affects participation, and what we do about it.\n\n## Mapping ICHI to dyscalculia support\nICHI is structured on three axes — **Target** (the entity acted on), **Action** (what is done), and **Means** (how). For a young child with mathematics impairment, clinically relevant intervention categories include:\n\n- **Assessment interventions** — structured evaluation of cognitive functions, attention, working memory and academic numeracy skills, establishing a functional baseline.\n- **Training and therapy interventions** — directed at *mental functions of calculation* and *acquisition of skills*: explicit, multisensory instruction in number sense, magnitude comparison, counting, place value and arithmetic fluency.\n- **Education and counselling interventions** — for the family and the school, including guidance on accommodations, and on supporting numeracy practice in everyday routines.\n- **Support and case-coordination interventions** — liaison with the educational setting so reasonable adjustments and a graded learning plan are in place.\n\nThe precise ICHI code stems are selected by the assessing clinician against the child's functional profile; the diagnostic anchor remains ICD-11 6A03.2, with severity and participation impact described via the ICF.\n\n## A note on age\nA formal diagnosis of mathematics impairment is generally meaningful only once structured numeracy instruction has begun — typically from around age 6–8 — because difficulty must be marked and persistent relative to expected attainment. In younger children, the appropriate stance is to **observe and support emerging number sense** (counting, quantity comparison, one-to-one correspondence) and route any persistent concern to a general developmental check rather than to premature labelling.\n\n## The Pinnacle way\nDevelopmental measurement supports care planning; diagnosis requires an appropriately qualified healthcare professional., under qualified clinician care — never from an online form. From there, intervention is mapped to the child's functional profile and reviewed on a measurable cadence.
