Developmental Screening

Answers from an early childhood expert

Experts and top early childhood organizations agree: Developmental screening is one of the best things you can do to get a child off to a great start in school and life. But what exactly is the screening process like, and how can professionals get parents engaged and involved—not only in screening, but also in promoting their child’s healthy development?

Jane Squires, Ph.D.

Today we have a true expert on hand to answer these and other key questions. Joining us for a Q&A is Jane Squires, Ph.D., a professor of special education at the University of Oregon and co-developer of the internationally renowned Ages & Stages Questionnaires® (ASQ®). For decades, Dr. Squires has been making a profound difference in the field of early childhood special education, with her groundbreaking work on screening, assessment, and early identification of developmental delays. We’re honored to have her here today to answer seven commonly asked questions about screening and development.


Q1: Many parents hear about “developmental milestones” a lot, but they may not know exactly what that term refers to. What are developmental milestones, and why do they matter so much?
Developmental milestones are skills that children usually display by certain ages, such as sitting on their own around 9 months and taking their first steps around 12 or 14 months. Checking the milestones your child has reached at a certain age is one way to make sure their development is on track.


Q2: What is developmental screening, and why is it important for all kids to be screened in early childhood?
Developmental screening is a brief “snapshot” of a child’s current skills. Screening divides children into two groups: those who appear to be on track and those who appear to need follow up. It’s important to screen because the earlier a child receives needed help, the better the outcome. Screening should be done throughout the early childhood years to make sure a child is developing as they should.


Q3: “Screening” is a word that makes some parents feel a bit apprehensive. What would you say to a parent who’s afraid to have a screening conducted, because they fear their child might be judged or labeled?
Screening is an odd word. I think of screening as a way of “sifting” through lots and lots of children to find any that may need a little help to make sure they’re meeting their milestones on time. This sifting is important to find children who may need some extra help, as well as those who are typically developing and don’t need any help at this time.

Screening is best done in a universal way. This means that all young children between birth and school age should have their developmental skills looked at periodically in an objective way, using valid and reliable screening assessments, to figure out whether they need extra help and what areas they might need help in.


Q4: Some professionals and parents may be skeptical that a parent-completed screener like ASQ can capture an accurate picture of the child’s skills and development. What are the main benefits of parent-completed screeners, and why are they so accurate and reliable?
Parent-completed screeners are accurate and reliable when they are carefully constructed, with input from parents and other caregivers about what is important to them. If a screening measure asks about children’s current, observable behaviors, we know that parents are able to observe their child and report accurately about what they can and cannot do.

There are several benefits of using screeners completed by parents and other caregivers who know a child well. First, parents see their children across settings and observe them interacting with different people, so they have a good sense of what their child can do and what things they’re still learning. Parents also know how to get optimal behaviors from their child by making sure they are rested and comfortable and using toys and objects that are of interest. Finally, it’s been shown that parents learn as a result of completing developmental questionnaires, so they may be able to give their child better learning experiences as time goes on.


Q5: Parents who hear that their child will be screened may wonder what they can expect after the screening is done. Can you walk us through what typically happens after a screening, and what next steps parents may be encouraged to take?
In most cases, the child will have a “typical” screening result, and programs should share this result soon after screening. If parents have concerns, and/or if the screening measure shows that a child’s milestones may not be on track, then the family and provider should discuss next steps together. In most cases, programs will suggest a referral to the early intervention or early childhood special education program for further assessment. This assessment might show the child is fine and should be screened again in four to six months. Or the assessment might suggest that the child should be referred for more supports and services to get their development back on track.


Q6: What are some of the best things that parents do to encourage healthy development between screenings? If a child has specific areas they need to work on, what should parents do to address those things?
Talking with your child every day as you go through your regular routines is one of the best things to do. Ask your child questions, sing a song together, comment on what you’re seeing or doing, take your child outside and talk about what you see. In addition to talking, reading books to your child helps with their language, understanding of the world, and relating to other people and things.

If your child needs specific help, there are activities that accompany each of the ASQ questionnaires that can give you some ideas for fun games and things to play with together. The ASQ Learning Activities also give some specific games and play ideas by domain or area. Looking at the ASQ items that your child couldn’t yet do—like writing with a pencil or bouncing a ball—can also give you some ideas about which skills to practice.

There are also many websites that feature parenting activities. You might want to take a look at:


Q7: Where can parents and professionals go if they want to learn more about milestones and developmental screening? Do you have some favorite resources you can direct them to?
Learn the Signs. Act Early. is a wonderful website from the Centers for Disease Control and Prevention that has milestones, videos, activity ideas, and lots of information for families who may have questions about their child’s development and what next steps to take. is another great website; in addition to information about ASQ, you’ll find learning activities, free resources, and guidance on next steps. Zero to Three’s website provides lots of parenting and development information—there are different sections about early development, early learning, parenting, and advocacy. And the Parent Website of the American Academy of Pediatrics.

Parents can also complete a free online developmental screening for their child using the research version of the Ages & Stages Questionnaires available at Upon completion, parents will also be given activities that they can do with their child to support development.

Each state also has an early childhood website that talks about services and supports in that state. There is usually information about the EI/ECSE programs in the area and where to go if you have any concerns about your child. The Early Childhood Technical Assistance Center allows you to search by state for Section 619 Preschool Coordinators and Part C Coordinators. You can also visit the Center for Parent Information and Resources website, which acts as a central hub of information for the network of parent centers serving families of children with disabilities. There, you can locate the contact information and websites for nearly 100 Parent Training and Information Centers and Community Parent Resource Centers across the country.

    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.
