What is the ASQ-3 and what does it assess?

A short, parent-friendly questionnaire that turns your everyday observations of your child into a clear picture of how their development is unfolding — that is the ASQ-3.

In short

The Ages & Stages Questionnaires, 3rd edition (ASQ-3) is a widely used developmental screening tool, completed by parents or carers, that checks how a child is progressing across five areas of development between the ages of 1 month and about 5½ years. It is a screen, not a diagnosis — it gently flags whether a child is developing as expected or might benefit from a closer look. Each age-specific questionnaire takes only a few minutes and is based on simple things you have already seen your child do.

What the ASQ-3 assesses

The ASQ-3 looks at five developmental domains together, giving a rounded view of your child rather than focusing on a single skill:

• Communication — listening, understanding and early talking.
• Gross motor — big movements like sitting, crawling, walking and running.
• Fine motor — hand skills such as grasping, stacking and using a crayon.
• Problem solving — how a child explores, plays and learns about the world.
• Personal-social — self-care and getting along with others.

There are separate questionnaires tuned to specific ages, so the questions always match what is typical for your child's stage. You answer with a simple yes, sometimes or not yet for each item. The result either reassures you that development is on track, or suggests it is worth a professional developmental review — it never labels or diagnoses. A few not yet answers are completely normal; ASQ-3 simply helps you and your clinician decide whether to watch, encourage or assess further.

When a screen leads to a closer look

Think of the ASQ-3 as a helpful first checkpoint, much like a height or vision check. If results fall below the expected range in one or more areas, the next step is a comprehensive developmental assessment by a qualified clinician — not worry. Screening done at regular intervals helps catch supportable differences early, when playful, targeted help works best.

The Pinnacle way

A screening questionnaire is only a starting point — a clinical AbilityScore® and any diagnosis are formed only at a Pinnacle Blooms Network centre, under qualified clinician care, never from a form or app alone. We use structured screens like the ASQ-3 as one input, then build a complete picture across communication, motor, play and social skills, drawing on speech therapy and other supports as needed.

Next step — If a screen has raised a question, or you simply want clarity on your child's development, book a developmental review to understand their strengths and start any helpful support early.
