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

    “What I love about the ASQ is that it allows our staff to catch delays quickly and allows us to get our clients the early intervention programs that they sometimes need. In many cases [ASQ] helps us catch children up before they start kindergarten, therefore providing children with the start that they deserve.
