About ASQ - Ages and Stages

ASQ: accurate, reliable developmental and social-emotional screening.

Ages & Stages Questionnaires® (ASQ ®) provides reliable, accurate developmental and social-emotional screening for children between birth and age 6. Drawing on parents’ expert knowledge, ASQ has been specifically designed to pinpoint developmental progress and catch delays in young children—paving the way for meaningful next steps in learning, intervention, or monitoring.

What ASQ Users are Saying

We chose ASQ because it is easy to do, low cost, culturally sensitive, and it meets our purpose of basic screening for our children’s development. Our infant teachers base their curriculum on each individual child based on the ASQ.
