Research & Results

ASQ: proven by research, data, results and ongoing user input.

Nearly 40 years ago, experts from the University of Oregon’s Early Intervention Program set out to develop a high-quality developmental screening system to accurately identify children who may be at-risk for delays—that was also cost-effective and easy to use. The result was Ages & Stages Questionnaires® (ASQ®), the first to rely on parent report and one that set the standard for valid, reliable, and affordable developmental screening.

    What ASQ Users are Saying

    ASQ-3 has helped make our staff and our families more aware of developmentally appropriate growth and development. The resources that come with the ASQ-3 have been instrumental for parents to provide school readiness activities at home and to understand the objectives that we cover in our plans.”
