Ages & Stages Questionnaires® (ASQ)

The Ages & Stages Questionnaires®, Third Edition (ASQ®-3) is a developmental screening tool that pinpoints developmental progress in children between the ages of one month to 5 ½ years. Its success lies in its parent-centric approach and inherent ease-of-use—a combination that has made it the most widely used developmental screener across the globe. 

Evidence shows that the earlier development is assessed—the greater the chance a child has to reach his or her potential. Learn more about the ASQ-3 HERE.
