What is the ASQ Screener?

ASQ, published by Brookes Publishing, is a research-based developmental screening tool designed for children ages 1 month to 5½ years.

It focuses on key developmental milestones and helps determine whether a child is progressing as expected for their age.

Who completes ASQ?

ASQ is typically completed by:

• Families or caregivers who know the child best
• Educators, who may support or collaborate in the process

This shared approach helps create a more complete and accurate picture of the child.

Why is ASQ used?

ASQ is used to:

• Identify potential developmental delays early
• Determine if further evaluation may be needed
• Support early intervention and learning opportunities
• Strengthen communication between families and educators

What Developmental Areas Does ASQ Measure?

ASQ evaluates development across five key domains. These areas provide a well-rounded snapshot of a child’s growth. These domains help identify strengths as well as areas where additional support may be helpful.
