Developmental screening is a quick, broad check that flags whether a child needs a closer look, while diagnosis is an in-depth evaluation by qualified clinicians that precisely identifies and names what is happening. Screening is the gateway; diagnosis is the full map. AbilityScore® is part of Pinnacle’s developmental assessment. Diagnosis, where needed, requires an appropriately qualified healthcare professional.

*Screening asks a simple question — "shall we look more closely?" — while diagnosis gives the clear, careful answer.*

## In short
A **developmental screening** is a quick, broad check that flags whether your child might need a closer look — it is a signpost, not a label. A **diagnosis** is a detailed, in-depth evaluation by qualified clinicians that explains exactly what is happening and names it precisely. Think of screening as the *gateway* and diagnosis as the *full map*. A child can pass through screening and never need anything further, or be gently guided towards a fuller assessment.

## How they differ
- **Purpose** — Screening sorts children into "developing as expected" or "worth a closer look". Diagnosis identifies the specific nature, cause and pattern of a child's strengths and difficulties.
- **Depth and time** — A screen is short and standardised, often using questionnaires or quick observations. A diagnostic assessment is longer, multi-disciplinary, and looks across speech, movement, play, social skills and behaviour.
- **Who does it** — Screening can be done by a paediatrician, a health worker, or as part of a routine check. A diagnosis is made only by qualified clinicians using structured tools and clinical judgement.
- **The outcome** — A screen says *whether* to investigate further. A diagnosis says *what* is happening and shapes the right support plan.
- **What it is not** — A screen alone never confirms a condition, and a worrying screen does not mean something is wrong. It simply opens the door to clarity.

Both matter. Screening catches concerns early, when support is most powerful; diagnosis turns that early signal into a precise, child-centred plan.

## When to seek a check
If a routine screen flags a concern, or if you notice your child is not meeting milestones in speech, movement, play or social connection, a fuller developmental check is the next sensible step. Early action is never about labelling — it is about giving your child every advantage, sooner.
