Referring a child with suspected dyscalculia for developmental therapy

A bright child who stalls only on numbers is not careless — and knowing when to act turns concern into a clear referral pathway.

In short

Refer for developmental assessment when a child shows persistent, unexpected difficulty with number sense, arithmetic facts or calculation that is disproportionate to age, schooling and general ability, and that has not responded to good classroom instruction over at least one to two terms. Dyscalculia (ICD-11 6A03.2, developmental learning disorder with impairment in mathematics) is reliably identifiable from around age 7–8, once formal arithmetic has been taught — but earlier numerical red flags in a struggling 5–6-year-old warrant monitoring and a developmental check rather than a wait-and-see dismissal.

When to refer — the clinical decision

Refer when you see a pattern, not a single weak test:

• Persistence — difficulty enduring beyond two terms of targeted teaching and home support (response-to-intervention failure).
• Discrepancy — maths attainment markedly below that expected for age and intellectual ability, with relatively spared reading and language.
• Core deficits — poor subitising and magnitude comparison, finger-counting persisting well past peers, weak arithmetic-fact retrieval, place-value confusion, difficulty with time, money and estimation.
• Functional impact — measurable effect on academic progress, with rising frustration, maths anxiety or avoidance.
• Exclusions first — rule out uncorrected sensory deficits, inadequate schooling, and consider co-occurring ADHD, dyslexia or anxiety, which frequently cluster with dyscalculia.

Refer promptly (do not defer to repeated school review) where there is significant emotional distress, regression in confidence, or a strong family history of learning disorder.

The Pinnacle way

At a Pinnacle Blooms Network centre, a clinician translates your referral into a structured, clinician-administered AbilityScore® profile — measuring the child against their own baseline across numerical cognition, working memory and attention — before any diagnosis is considered. A clinical diagnosis and AbilityScore® are formed only at a Pinnacle Blooms Network centre, under qualified clinician care, never from an online form or a single score. From there, individualised learning-support and developmental therapy targets number sense and arithmetic fluency in a strengths-led way. Drawing on 25 million+ therapy sessions and 4.95 lakh+ families served across 70+ centres, the aim is a confident learner in the mainstream classroom.
