The ASQ-3 (Ages & Stages Questionnaires, Third Edition) is a parent-completed developmental screening tool used for children from 1 month to 66 months of age — about 5½ years. It uses 21 age-specific questionnaires so the questions always match a child's stage, screening five areas: communication, gross motor, fine motor, problem solving and personal-social. It is a screen that flags whether a closer look may help, not a diagnosis.

*One gentle questionnaire, completed by you, that meets your child where they are — from the first months of life through to starting school.*

## In short
The **Ages & Stages Questionnaires, Third Edition (ASQ-3)** is a parent-completed developmental screening tool used for children from **1 month to 66 months of age** (about 5½ years). It comes as a series of age-specific questionnaires — 21 in total — so the questions always match your child's stage, from early infancy right up to the start of school. It is a screening tool that flags whether a child may benefit from a closer look — not a diagnosis.

## How the age range works
Rather than one form for every child, ASQ-3 uses **separate questionnaires at set age intervals** — for example around 2, 4, 6, 9, 12 months and onward — so the developmental questions stay relevant as your child grows. Each questionnaire asks you, the parent, about everyday skills across five areas: communication, gross motor, fine motor, problem solving, and personal-social. Because parents see their child every day in familiar settings, your observations make this a wonderfully practical first step. The intervals are closer together in the early months, when development moves quickly, and a little wider as children grow. The full span runs from **1 month up to 66 months**, which neatly covers the early-childhood window when timely support makes the biggest difference.

## What a screen tells you — and what it doesn't
ASQ-3 is designed to be a **screen, not a diagnosis**. A result simply tells you whether your child is developing comfortably for their age or whether some areas might benefit from a closer professional look. A score that suggests follow-up is an invitation to understand more — never a label, and never a cause for alarm. Many children flagged by a screen go on to thrive, sometimes with a little targeted support, sometimes with none at all.

## The Pinnacle way
This is general information, not a diagnosis — a clinical [AbilityScore®](/ask/what-is-the-abilityscore-and-how-is-it-calculated) and any diagnosis are formed only at a Pinnacle Blooms Network centre, under qualified clinician care, never from an app or form alone. If an [ASQ-3](/asq-3) screen or your own watching raises a question, our team can map the whole picture across communication, motor and social skills and, where helpful, draw on [speech therapy](https://www.pinnacleblooms.org/top-speech-therapy-center-india-proven-improvement-rate) and other supports tailored to your child.

## Trusted sources
CDC guidance on developmental monitoring and screening tools; the American Academy of Pediatrics and HealthyChildren on developmental surveillance through early childhood; WHO Nurturing Care Framework on early childhood development.

**Next step —** If you'd like a clearer picture of how your child is developing, book a developmental review and let our clinicians turn observations into a personalised plan.
