The autism testing locations near Deerfield provide a comprehensive approach, offering a range of services including diagnostic evaluations and therapy recommendations in a welcoming environment. Each evaluation is tailored to your child's unique needs.

Why Early Autism Testing Matters

Autism spectrum disorder (ASD) affects communication, social interaction, behavior, and sensory processing. While autism can be diagnosed later in childhood, many signs begin to appear in the toddler years.

Research consistently shows that early identification leads to better outcomes because children can begin therapy during key developmental stages. Early autism testing supports a child's development and child's growth by enabling timely access to therapies that foster communication, social skills, and cognitive abilities.

Early autism testing can help:

• Identify communication delays
• Clarify social engagement differences
• Address sensory sensitivities
• Open access to early intervention services
• Provide families with guidance and support

A comprehensive approach to early intervention is designed to support all aspects of a child's development and growth, ensuring a continuum of care that addresses communication, social, and cognitive milestones.

For children under age four, development happens rapidly. Early autism evaluations allow families to take advantage of this critical learning window.

Signs Your Toddler May Benefit From Early Autism Testing

Every child develops at their own pace. However, certain patterns may indicate that an autism evaluation could be helpful.

Parents in Deerfield and surrounding communities often seek autism testing for toddlers when they notice signs such as:

• Limited or no words by 18–24 months
• Not responding consistently to their name
• Limited pointing, waving, or gestures
• Difficulty making eye contact
• Reduced interest in social interaction
• Repetitive movements such as rocking or hand flapping
• Strong reactions to sounds, lights, or textures
• Intense distress with changes in routine
• Limited pretend play

Early autism testing can also help identify other developmental disorders and learning disorders that may impact a child's progress. The evaluation process for children aged 18 months to 4 years is designed to assess behavioral, social, and communication development.

Noticing these signs does not necessarily mean a child has autism. However, when developmental concerns persist, an early autism evaluation can provide clarity and direction.

Many parents say they had a “gut feeling” that something was different. Trusting that instinct can help families seek support sooner.

What Happens During Early Autism Testing?

Parents sometimes feel anxious about scheduling autism testing because they are unsure what the evaluation process involves. In reality, early autism testing for toddlers often feels like structured play.

At our Deerfield clinic, the evaluation process typically involves a comprehensive neuropsychological assessment to evaluate cognitive functioning, behavior, and development. The evaluation process may include standardized tests, interviews, and observations, and is often conducted by a team of specialists such as psychologists, speech therapists, and pediatricians. The results of the evaluation process can influence treatment options, including therapy recommendations and educational support.

1. Parent Interview and Developmental History

The evaluation begins with a detailed conversation about your child’s development.

Parents are asked about:

• Early developmental milestones
• Communication and language development
• Social engagement
• Behavioral patterns
• Sensory sensitivities
• Family and medical history

Parents know their children best, and this information helps clinicians understand the full picture of a child’s development.

This portion of the evaluation typically takes 60–90 minutes.

2. Play-Based Observation and Assessment

The next part of the evaluation involves direct interaction between the clinician and your child.

For toddlers and young children, this looks like guided play activities designed to observe developmental behaviors.

Clinicians may evaluate how a child:

• Responds to their name
• Uses gestures or pointing
• Engages socially with adults
• Plays with toys
• Imitates actions
• Communicates wants and needs
• Responds to changes in activity

These observations help clinicians understand social communication patterns and behaviors associated with autism spectrum disorder.

Testing sessions typically last two to four hours, sometimes divided into shorter segments depending on the child’s attention span.

3. Evidence-Based Autism Assessment Tools

Our clinicians use standardized assessment tools designed specifically for young children. North Shore Pediatric Therapy uses the ADOS-2, a standardized, play-based observation tool, as part of early autism evaluations. Neuropsychological testing may also be included to assess cognitive and behavioral functioning.

These tools help measure behaviors related to:

• Social interaction
• Communication development
• Repetitive behaviors
• Play skills

Combining these structured tools with clinical observation ensures that autism evaluations are both thorough and accurate.

4. Clinical Analysis and Scoring

After testing is complete, clinicians carefully analyze results and compare observations to established diagnostic criteria. Evaluations are typically led by licensed neuropsychologists or developmental pediatricians at specialized clinics.

This step ensures that the evaluation is comprehensive and accurate. Comprehensive neuropsychological evaluations can help identify autism, psychiatric conditions, and other developmental concerns.

Because early childhood development is complex, careful analysis is essential to determining whether autism spectrum disorder may be present. The Goldman Center of Chicago provides comprehensive diagnostic evaluations for autism and related conditions.

5. Feedback Session and Next Steps

Once the evaluation is complete, parents meet with the clinician to review results.

During this session, families learn:

• Whether the child meets criteria for autism spectrum disorder
• The child’s developmental strengths
• Areas where support may be helpful
• Recommendations for therapy or intervention

Parents also receive a detailed written report documenting the evaluation results.

This report can be shared with pediatricians, therapists, and early intervention providers.

Our Early Autism Testing Clinic was designed to streamline the process.

• Intake, evaluation, and feedback occur within a short timeframe
