Autism Testing for Children in Deerfield, IL: A Complete Guide for Families

Why Parents Seek Autism Testing

Parenting comes with endless questions, and one of the most important ones arises when you notice your child’s development looks different from peers. Monitoring your child's development and tracking milestones is crucial for identifying any early concerns. Maybe your toddler isn’t talking yet, avoids eye contact, or prefers playing alone. Perhaps your older child has an advanced vocabulary but struggles to connect socially. In these moments, many parents ask themselves:

• Should I be concerned?
• Is this just a phase?
• Could my child be on the autism spectrum?

These are natural, caring questions, and you don’t have to answer them alone. At the Chicago Autism Testing Institute in Deerfield, we provide families with expert, compassionate autism testing for toddlers and children.

Our goal is to bring clarity. A thorough evaluation doesn’t just identify whether autism may be present—it helps families understand their child’s strengths, challenges, and the best path forward. With clear answers, families can move past uncertainty and take confident steps to support their child’s growth.

The Power of Early Autism Spectrum Disorder Testing

Research consistently shows that early identification of autism leads to better outcomes. Well-child visits are key opportunities for developmental screening and early detection of autism, as they are scheduled regularly and include important screenings for conditions like autism spectrum disorder (ASD). Toddlers and children who receive an autism diagnosis can begin early intervention services such as speech therapy, occupational therapy, or ABA therapy sooner. These supports can significantly improve communication, social interaction, and daily living skills.

At our Deerfield center, we often evaluate children as young as 18 months old. A screening tool is often used by healthcare professionals to identify early signs of autism during these evaluations. While every child develops at their own pace, it’s never “too early” to get answers. In fact, families often share that having clarity—even if the evaluation does not result in an autism diagnosis—brings a sense of relief and direction.

Common Signs in a Child's Development That May Lead Parents to Seek Autism Testing

Every child is unique, and no two autistic children look exactly alike. Parents and professionals often monitor a child's development and compare it to that of other children to identify any concerns. However, there are patterns that may prompt families to pursue an evaluation. Observing a child's behavior and tracking a child's symptoms over time can help determine if an evaluation is needed.

Here are some common signs:

In Toddlers

• Limited use of words or no words by 18–24 months
• Not responding consistently to their name
• Limited or absent pointing to show interest
• Difficulty making eye contact
• Engaging in repetitive movements, like hand-flapping or rocking
• Limited or absent imaginative play, such as pretending with toys or objects.

In Preschool and School-Age Children

• Using advanced vocabulary but struggling to hold back-and-forth conversations
• Strong focus on specific interests while showing little interest in other topics
• Difficulty understanding social cues, like tone of voice or facial expressions
• Becoming upset by small changes in routine
• Sensory sensitivities—such as covering ears for certain sounds or refusing certain clothing textures
• Engaging in repetitive behaviors, such as repeating phrases or routines.

It’s important to note: seeing one or two of these signs doesn’t mean a child has autism. But if parents notice multiple patterns or have a persistent gut feeling that something is different, an evaluation provides valuable answers.

What Happens During Autism Testing in Deerfield

Parents often feel nervous before an evaluation because they don’t know what to expect. At the Chicago Autism Testing Institute – Deerfield, we work hard to make the process clear, supportive, and child-friendly.

Here’s how it works step by step:

1. Parent Interview and Developmental History
   We begin by talking with you about your child’s history—pregnancy, birth, milestones, and any concerns you’ve noticed. This conversation is not a test—it’s a collaboration. Parents are experts in their children, and your insights are essential. We also gather information about family history, including any family members with learning disorders, intellectual disability, or other developmental or mental disorders, as well as the person’s developmental history.
2. Play-Based and Standardized Assessments
   Depending on your child’s age, we’ll use gold-standard autism testing tools such as the ADOS-2 (Autism Diagnostic Observation Schedule) or other validated measures. For toddlers, this often looks like playful activities designed to see how they communicate, engage, and respond. For older children, the evaluation may include more structured tasks. A child psychologist, developmental pediatrician, or occupational therapist may be involved in the formal evaluation. Diagnostic tests are used to assess cognitive functioning, body language, nonverbal communication, and social communication.
3. Behavioral Observation
   Our clinicians carefully observe how your child interacts with toys, responds to social bids, and communicates. These observations reveal patterns that may not be visible in everyday life. We also observe the child’s strengths and behavior in various contexts, including school settings if applicable.
4. Scoring and Clinical Analysis
   Data from assessments and observations are analyzed against developmental expectations. Our clinicians combine this information with parent input for a complete picture. There is no single blood test for autism; the process relies on behavioral and developmental assessments.
5. Feedback Session with Parents
   After the evaluation, we meet with parents to review results. We’ll discuss whether your child meets criteria for autism, or whether another developmental difference may explain their profile. We also discuss the possibility of re-evaluation in the future if your child’s needs change, and mention conditions such as Asperger syndrome and other mental disorders that may be considered during diagnosis. Importantly, you’ll leave with clear next steps—whether that’s starting therapy, requesting school supports, or pursuing additional evaluations.

Autistic individuals can benefit from this early identification, and parents often share that this session brings relief because it replaces worry with a concrete plan.

Resources for Families Navigating Autism Testing

Navigating the journey of autism testing can feel overwhelming, but families in Deerfield have access to a wealth of resources designed to support them every step of the way. The first and most important resource is your child’s healthcare provider or pediatrician. These medical professionals are experienced in recognizing early signs of autism spectrum disorder (ASD) and can guide you toward the most appropriate next steps, including referrals to specialists in developmental and behavioral pediatrics.

When it comes to diagnosing autism, a comprehensive evaluation is key. This may involve a combination of neuropsychological testing, occupational therapy assessments, and speech-language evaluations to fully understand your child’s strengths and challenges. Tools such as the Autism Diagnostic Observation Schedule (ADOS) and other autism screening tools are often used by specialists to identify children with autism spectrum disorder. The Diagnostic and Statistical Manual (DSM-5), published by the American Psychiatric Association, serves as the standard reference for diagnosing autism spectrum disorder and other developmental disorders. If you have concerns about your child’s development, using autism screening tools such as the Modified Checklist for Autism in Toddlers (M-CHAT) can help identify early signs and determine if further assessment is needed.

It’s important to remember that a formal diagnosis of autism spectrum disorder is not a prediction of your child’s future. With the right support, children with autism can thrive, develop social skills, and reach their full potential. Early intervention is crucial for children with autism, and research shows that starting evidence-based practices like behavior therapy as soon as possible leads to more positive outcomes. Staying informed about the latest advancements in autism spectrum disorder, including new diagnostic tools and therapies, empowers families to make the best decisions for their child’s development.

By working closely with your child’s doctor, accessing early intervention services, and connecting with local resources, you can ensure your child receives the support they need to grow and succeed. Remember, you are not alone—there is a strong community and a network of professionals ready to help your family every step of the way.
