When to Get Child Tested for Autism: Signs and Next Steps

Autism Spectrum Disorder (ASD) is a complex developmental condition that affects how children communicate, learn, and interact with others. Parents often wonder when to get a child tested for autism, as early signs of autism and early detection can significantly improve outcomes. The American Academy of Pediatrics (AAP) recommends routine well-child visits to monitor developmental milestones and identify possible signs of autism as early as 18 months.

A child’s pediatrician plays a vital role in recognizing developmental delays and guiding families toward further evaluation when needed. Understanding the basics of ASD empowers parents to seek help from their child’s doctor at the right time and access early intervention services that support their child’s learning and social skills.

Child Development and Autism Spectrum Disorder

Autism spectrum disorder can affect many children’s social, communication, and cognitive skills, sometimes causing noticeable delays in development compared to peers. Developmental milestones like making eye contact, responding to their name, or using gestures often occur later or differently in children with ASD.

Pediatricians and child healthcare providers use developmental screening tools to monitor progress at routine visits. These tools help determine if your child’s development is on track or if further evaluation by developmental and behavioral pediatrics is recommended. If developmental delays are detected, early intervention services can address these challenges before they impact school readiness and overall behavioral health.

Early Signs and Identification

You may wonder when to get your child tested for autism. Early signs can be subtle, and not all autistic children display the same behaviors. Parents should watch for developmental differences during regular well-child visits as early as 12–18 months. Some common early indicators include:

• Limited eye contact or lack of response to their name
• Delayed speech or loss of previously acquired language skills
• Repetitive behaviors, such as hand-flapping or lining up toys
• Difficulty engaging in social interactions or pretend play
• Strong resistance to changes in routine or environment

If you observe these behaviors, bring your concerns to your child’s pediatrician. A doctor can recommend an initial evaluation or further evaluation by an autism specialist or developmental pediatrician. The Centers for Disease Control and Prevention (CDC) provides additional resources to help parents understand early identification and signs of ASD.

Autism Evaluation

An autism evaluation is a comprehensive process conducted by a multidisciplinary team of professionals. This may include a developmental pediatrician, child psychologist, occupational therapist, and other specialists.

The evaluation typically involves:

• Reviewing developmental and medical history with parents
• Observing the child’s social, communication, and play behaviors
• Administering standardized tools like the Autism Diagnostic Observation Schedule (ADOS)
• Performing additional medical tests, such as metabolic screenings, to rule out underlying conditions

This in-depth information allows professionals to determine whether a child meets the criteria for an ASD diagnosis. Early detection through a thorough evaluation is key to accessing appropriate therapies and interventions.

Autism Diagnosis and Developmental Disorders

Receiving an autism diagnosis can feel overwhelming, but it is essential for accessing the right support and services. An ASD diagnosis confirms that a child meets the criteria outlined by the American Psychiatric Association for autism spectrum disorder.

Autism often co-occurs with other developmental disorders, such as intellectual disability or speech delays. A comprehensive diagnosis helps create a holistic treatment plan that addresses all aspects of a child’s development. With a formal diagnosis, parents can access evidence-based therapies like ABA therapy, occupational therapy, and speech therapy tailored to their child’s needs.

Behavioral Health and Autism Treatment

Behavioral health plays a critical role in autism treatment. Children with ASD may experience challenges like repetitive behaviors, self-injury, or anxiety. Applied Behavior Analysis (ABA) therapy is a widely used intervention that focuses on developing new skills and reducing problematic behaviors through positive reinforcement.

Early intervention is essential. Studies show that children who receive services before age 3 make the most progress. Pediatricians and behavioral pediatric specialists can help families navigate available services in their community, whether through private therapy, early childhood programs, or school systems.

ABA Therapy and Intervention

ABA therapy is one of the most effective interventions for children with autism. This structured therapy uses evidence-based techniques to teach communication, self-care, and social skills. ABA programs are individualized based on a child’s developmental level and can be provided in home, school, or clinic settings.

Research shows that children who begin ABA therapy shortly after diagnosis demonstrate significant improvements in skill development and independence. Because each child is unique, therapists work closely with parents to set goals and track progress over time.

Supporting Your Child

Support for a child with autism extends beyond therapy sessions. Parents play an active role in creating an environment where their child can thrive. This includes building routines, using visual supports, and practicing communication strategies at home.

It’s also important to seek guidance from professionals like pediatricians, occupational therapists, and special educators. A well-coordinated support plan may include:

• ABA therapy and other evidence-based interventions
• Occupational and speech therapy
• Parent training and education to reinforce strategies at home
• Emotional support for family members through counseling or support groups

The more informed and supported a family feels, the more effectively they can advocate for their child’s needs.

Autism in Toddlers

Autism can be reliably diagnosed in toddlers as young as 18 months, though signs may be noticeable earlier. Toddlers with autism may display behaviors such as avoiding eye contact, not responding to their name, or engaging in repetitive motions.

If you have concerns about your toddler’s development, speak with your pediatrician immediately. They can administer a screening tool like the Modified Checklist for Autism in Toddlers (M-CHAT) and refer you for a full evaluation if needed. Early intervention services at this stage can make a significant difference in a child’s developmental trajectory.

Navigating the Autism Diagnosis Process

The process of obtaining an autism diagnosis can feel overwhelming, but parents don’t have to navigate it alone. Pediatricians are typically the first point of contact and can refer families to specialists for a formal evaluation.

Parents should be prepared to:

• Share detailed information about their child’s developmental history and behaviors
• Participate in observation-based assessments
• Ask questions about the evaluation process and results

A diagnosis from a qualified autism specialist or developmental pediatrician opens the door to therapies, school-based supports, and community services.

Creating a Support Plan

Once a child receives a diagnosis, creating a comprehensive support plan is essential. This plan should be tailored to the child’s unique strengths and challenges and may include:

• ABA therapy and other behavioral interventions
• Occupational and speech therapy for skill development
• Special education services through local school systems
• Family-centered resources such as parent training and respite care

Pediatricians and other medical professionals can help coordinate services and ensure your child’s needs are met consistently.

Next Steps After Diagnosis

After an autism diagnosis, parents may feel uncertain about what to do next. The first step is to connect with your child’s pediatrician or autism specialist to discuss available therapies and resources.

Early intervention is the most effective way to support children with ASD, so prioritizing timely access to services is key. Parents should also seek out support groups, counseling, and educational resources to help them navigate the journey ahead.

Conclusion

Understanding when to get your child tested for autism is vital for their future development and well-being. Early identification and intervention allow children to build crucial social, communication, and life skills. By working closely with pediatricians, autism specialists, and a multidisciplinary team to identify asd symptoms, parents can create a strong foundation for their child’s success and quality of life.
