How to know if your child has autism?
As a parent, few things feel as heavy as wondering whether something might need attention in your child’s development. Maybe your toddler isn’t speaking as much as others their age. Perhaps they don’t make eye contact like other kids or seem overwhelmed by certain sounds or textures. If you’ve found yourself asking, “How to know if your child has autism?”, you’re not alone—and you’re in the right place to learn about the importance of an autism evaluation.
Getting an autism evaluation can feel overwhelming, but it’s one of the most important steps you can take if you notice early signs of developmental challenges. This blog by ABA Centers of America will guide you through the when, the why, and the how of getting your child tested. We’ll talk about autism screening, what symptoms to look for, what to expect from an assessment for autism, and how to take the following steps toward support and answers.
If you’d like to learn more about Autism Spectrum Disorder (ASD) and therapeutic support through Applied Behavior Analysis (ABA), we encourage you to explore our blog. We update it weekly with valuable information for parents, caregivers, and the entire neurodiverse community.
Why Early Autism Evaluation Matters
Early diagnosis changes lives. Research consistently shows that children who receive intervention at a young age experience better outcomes in communication, learning, and daily living skills.
According to the CDC, autism now affects about 1 in 31 children in the U.S., and many signs of autism appear before the age of two, making early autism evaluation essential.
The earlier parents seek an autism evaluation, the sooner children can access therapies that help them thrive, especially ABA therapy, the gold standard in autism treatment. That’s why organizations like the American Academy of Pediatrics (AAP) and the CDC recommend developmental screenings at 9, 18, and 24 or 30 months of age.
When to Test for Autism?
Healthcare professionals recommend routine autism screenings at 18 and 24 months during regular developmental check-ups with pediatricians.
These screening ages aren’t arbitrary; they align with when autism signs typically become more apparent and when early intervention can be most effective. However, if you have concerns about your child’s development at any age, don’t wait for the next scheduled screening.
Key Ages for Autism Screening
- 9 months – Developmental screening
- 18 months – General screening + first autism-specific screening
- 24 or 30 months – Second autism-specific screening
These recommendations help identify signs early on, even before your child has received a formal diagnosis.
If a child misses these milestones or shows behaviors that worry parents or pediatricians, it’s time to move beyond screening and begin a complete assessment for autism.
Early Signs of Autism in Children to Watch For
Understanding what to look for can help parents decide when to test for autism. While every child is unique, here are some signs that may appear in the first two years of life:
Signs at 12 Months
- Limited or no babbling
- Lack of response to their name
- Avoids eye contact
- Few warm, joyful expressions during interactions
- Doesn’t wave, point, or reach for objects
Signs at 18 Months
- Doesn’t use single words
- Shows no interest in pretend play
- Doesn’t point to show interest in objects
- Regression on previously acquired speech or social skills
- Unusual reactions to sensory experiences
Signs at 24 Months
- Doesn’t use two-word meaningful phrases
- Avoids imaginative play
- Displays repetitive behaviors like hand-flapping or rocking
- Has difficulty adapting to changes in routine
- Shows intense interest in specific objects or topics
These autism signs don’t confirm a diagnosis, but they’re strong indicators that it’s time for an autism evaluation.
The Autism Evaluation Process: What to Expect
When navigating autism testing with your loved one, understanding the expectations can help ease anxiety.
After an initial autism screening (usually done by a pediatrician), a team of professionals does a more detailed evaluation, including psychologists, developmental pediatricians, and speech-language pathologists. A comprehensive autism evaluation typically involves several components designed to provide a complete picture of your child’s development.
- Developmental Interview
Parents answer detailed questions about their child’s behaviors, communication, social interactions, and developmental history.
This conversation is crucial because parents often notice subtle differences that may not be apparent during a brief clinical observation.
- Direct Observation and Testing
Clinicians observe your child’s play, social behaviors, and communication. They often use tools like the ADOS-2 (Autism Diagnostic Observation Schedule) as part of this process.
- Additional Assessments
Clinicians may include cognitive testing, adaptive behavior scales, and speech-language evaluations to understand the child’s complete profile.
Many evaluation centers now offer telehealth options, making assessments more accessible for families in underserved areas or those who prefer the comfort of their home environment.
Additionally, these evaluations seek to support your child, not label them. Getting clarity early can open the door to life-changing resources like ABA therapy.
After the Diagnosis: What Comes Next?
Hearing the words “your child has autism” can feel overwhelming. An autism diagnosis can bring many emotions, like relief for having answers, concern about the future, and uncertainty about next steps. However, this is just the beginning of a hopeful and empowered path forward.
A diagnosis unlocks access to therapies, support systems, and educational services tailored to your child’s needs.
Many developmental specialists advocate for ABA therapy as an effective method for building new abilities and addressing behavioral challenges in children with autism spectrum disorder. This highly personalized approach uses positive reinforcement and carefully designed learning experiences, with each treatment plan customized to match the individual child’s unique strengths and developmental needs.
Early intervention services may also include speech therapy, occupational therapy, and developmental support programs. The key is creating a comprehensive support network that addresses your child’s unique needs while building on their natural abilities and interests.
At ABA Centers of America, we walk alongside families every step of the way, from that first autism evaluation through personalized, evidence-based ABA therapy services.
We understand that no two children with autism are the same. That’s why our approach is always individualized. Whether your child needs in-home therapy, support at school, or help developing communication skills, we’ll help build a plan that works for your family.
