The Ages & Stages Questionnaires® A Parent-Completed, Child-Monitoring System was developed at the University of Oregon in the early 1980s. The purpose of the ASQ-3 is to provide a low-cost strategy to screen and monitor the development of infants and young children whose developmental status is in question or at risk. The ASQ is composed of 21 separate age intervals for children in ages 1 month up to 66 months. ASQ-3 can be used by most parents to reliably report the developmental status of their infant or young child.

The ASQ-3 can be completed online in our research study, Oregon Screening Project.
