ASQ-3™

The parent-completed Ages & Stages Questionnaires®, Third Edition (ASQ-3™) is the most accurate, family-friendly way to screen children for developmental delays between one month and 5½ years, without any gaps between the questionnaire age intervals. Recommended by top organizations such as the American Academy of Neurology, First Signs, and The Child Neurology Society*, ASQ-3 is highly valid and reliable. ASQ-3′s questions on behavior and communication also help elicit parent concerns that may point to autism.

ASQ-3 questionnaires

are available in English or Spanish
take just 10–15 minutes for parents to complete and 2–3 minutes for professionals to score

can be completed at home, in a waiting room, during a home visit, or as part of an in-person or phone interview

Step 1

Choose the right questionnaire for the child’s age and give it to the parent—in person, by mail, or online through ASQ Family Access.

Step 2

Have the parent or primary caregiver answer yes, sometimes, or not yet for each item. (Before the first screening, explain the purpose of screening; use the “What Is ASQ-3?” handout found on the CD-ROM or in ASQ Online.)

Step 3

Scoring takes just 2–3 minutes—less with ASQ Online‘s automated scoring.

Step 4

Determine next steps. A quick review of the information on the summary sheet and the parent comment section shows you if any further assessment is needed.

Step 5

Share the results with families. Make referral recommendations and give them handouts on learning activities (such as those found in the ASQ-3™ Learning Activities, Second Edition) to help them promote their child’s development.

Step 6

For greatest convenience, manage your screening program with ASQ Online, which enables you to easily manage all of your ASQ data, run reports in seconds, import/export data, track referrals, and more.

Step 7

Screen children at regular intervals to monitor their progress so they can start getting help early—when it makes the greatest difference!
