    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.”

    What ASQ Users are Saying

    “I like the ASQ:SE, which is an easy non-threatening tool to use to assess important social-emotional developmental milestones of the baby…. This tool lends itself well to developing educational activities to foster a healthy parenting relationship.”

    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.”

    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.

Before you Begin

What’s My Role as a…


As an early childhood educator, you play a vital role in ensuring that every young child is screened. Start by partnering with parents to explain why developmental screening is so important, introduce ASQ, and address any concerns they might have. Once parents complete the questionnaires, ASQ makes it easy for you to score them and interpret the results. Then sit down with parents to share what the screener revealed, plan next steps, and give them tips and strategies for encouraging their child’s progress.

Program Administrator?

Program administrators lay the critical groundwork for a successful screening program. Your first role is to plan your program, from determining goals to choosing your screener. Once your plan is in place, train and support your staff on every step of screening, including engaging parents, communicating results sensitively, and connecting families with community resources for referral. You’ll also want to evaluate the success of your screening program and make periodic adjustments when necessary.

Because pediatricians are the professionals most likely to see a child on a regular basis, you’re in the perfect position to promote children’s healthy development and identify potential delays early. If your office doesn’t have a screening program yet, plan one with the help of the resources on this site. As parents complete ASQ through your program, your role is to score the questionnaires, interpret results, and sit down with families to share what you learned and plan next steps. In between screenings, give families learning activities and other resources to foster their child’s skills and development.

Coding Fact Sheet


You may not be a child development specialist, but you are the expert on your child—and research has shown that parents’ concerns are accurate predictors of developmental delays. Talk to an early childhood professional about the benefits of developmental screening, and complete the ASQ questionnaire that’s right for your child’s age (they’re easy to do and take just 10-15 minutes). When your child’s pediatrician or teacher shares ASQ results with you, celebrate the milestones your child has reached and ask what you can do next to support your child’s skills and healthy development.
