An AbilityScore of 300–400 confirms your child needs meaningful structured support now. But with developmental regression — losing previously held skills — prompt medical review comes first to rule out an underlying cause, alongside a clinician-led therapy plan built on this baseline.

*A score is a starting point, not a verdict — and with developmental regression, the most loving thing you can do is act promptly and gently.*

## In short
An AbilityScore in the **300–400 band** tells your clinician that your child currently needs meaningful, structured support across several areas — and that is exactly what therapy is built for. But with [developmental regression](/) — where a child *loses* skills they once had — there is one priority above all: a prompt medical review to rule out any underlying cause before therapy planning settles. The next step is not panic; it is a clinician-led assessment that turns this number into a clear, personal plan.

## What regression means — and why review comes first
Regression is different from a slow start. When a child loses words, eye contact, motor skills or play they previously had, clinicians want to understand *why* first. Some causes are medical and need a paediatrician or neurologist alongside therapy — so regression is one situation where a prompt medical opinion is sensible, not therapy alone.

- **Note what changed and when** — which skills, over what timeframe, and anything that coincided (illness, fever, seizures, a stressful event).
- **Watch for medical red flags** — staring spells, unusual movements, loss of muscle tone, or regression after a fever — these warrant prompt medical attention.
- **Keep a short video diary** — brief clips of play, speech and movement give your clinician far more than memory can.

The 300–400 band simply confirms the *current* level of support needed across communication, motor, social and daily-living skills. It is your child's own baseline — the line every future gain is measured against, so even quiet progress becomes visible.

## What happens next at Pinnacle
Your clinician reviews the regression history, coordinates any needed medical referral, and shapes a therapy plan — typically blending [speech therapy](https://www.pinnacleblooms.org/top-speech-therapy-center-india-proven-improvement-rate) and [occupational therapy](https://www.pinnacleblooms.org/best-occupational-therapy-center-india-proven-improvement-rate) — matched to your child's profile, not a generic template. Progress is then re-measured against this baseline, so you and your team can see what is working.

## The Pinnacle way
Developmental measurement supports care planning; diagnosis requires an appropriately qualified healthcare professional., under qualified clinician care — never from an online figure alone. Across 70+ centres in 4 states, 700+ therapists and 25 million+ therapy sessions, our work is to turn a number into a clear, hopeful plan for *your* child. Learn how the [AbilityScore is measured](/ask/what-is-the-abilityscore-and-how-is-it-calculated), explore [speech therapy](https://www.pinnacleblooms.org/top-speech-therapy-center-india-proven-improvement-rate), and start at [our network](/).

## Trusted sources
WHO ICD-11 framework for developmental and neurological conditions; American Academy of Pediatrics guidance on developmental surveillance and prompt review of skill loss; CDC developmental milestone resources; Pinnacle Blooms Network clinical studies.

**Next step —** With regression, prompt action is the kindest action. [Book an assessment](https://www.pinnacleblooms.org/enroll-autism-speech-aba-therapies-india) with a Pinnacle clinician, who will coordinate any medical review and build your child's plan.

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