Is your child developing differently from peers? Does your pediatrician recommend evaluation for autism? Finding clarity through a formal diagnosis helps you understand your child and access support. Chapel Hill and the surrounding area have excellent resources for autism assessment. This guide walks you through what evaluation involves, signs that suggest testing, how Medicaid covers it in North Carolina, and what happens after diagnosis.
Autism looks different in each child. It’s not one set of behaviors but rather a pattern across communication, social interaction, and repetitive or restricted behaviors. Consider evaluation if you’ve noticed:
Communication Delays or Differences
Social Challenges
Repetitive or Restricted Behaviors
Other Markers
Keep in mind that typical children show many of these behaviors sometimes. Autism involves a cluster of persistent differences that affect the child’s learning and daily functioning.
An autism evaluation is comprehensive and evidence-based. Here’s what to expect:
Your child’s pediatrician is usually the starting point. They can perform quick screening tools like the M-CHAT and refer you to a specialist if concerns emerge. You can also self-refer to a developmental pediatrician or clinical psychologist who specializes in autism.
The evaluation involves multiple components, typically conducted over 2-3 appointments:
Clinical Interview: You’ll provide detailed information about your child’s developmental history, milestones (when they walked, talked, began playing with other children), current behaviors and concerns, health history, and family background. Honest, thorough information helps the evaluator understand the full picture.
Direct Observation: The clinician watches your child during play, structured tasks, and conversation. They observe communication patterns, social interaction, behavior, sensory responses, and how your child handles changes or frustration.
Standardized Diagnostic Tools: Most evaluations include the ADOS-2 (Autism Diagnostic Observation Schedule) or similar assessments. These measure specific behaviors and social-communication patterns associated with autism. They’re designed to be engaging and appropriate for your child’s age.
Cognitive and Developmental Assessment: The evaluator may assess thinking skills, language development, adaptive functioning (daily living skills), or motor development depending on what information is needed for diagnosis.
Collateral Information: Input from teachers, therapists, or video of your child at home provides additional context.
The evaluation process typically takes 4-8 hours of testing across multiple visits, with results available 2-4 weeks after completion.
The evaluator meets with you to explain findings, answer questions, and provide recommendations. The diagnostic report includes:
An autism diagnosis means your child’s brain processes information and social interaction differently. It’s not a defect or a tragedy. It’s how your child is wired.
Communication patterns might include strengths in logical thinking or visual processing alongside challenges in social communication.
Sensory experiences might mean your child needs quiet to focus or seeks out physical movement to regulate emotions.
Social interaction might involve needing longer to warm up to new people, preference for predictable routines, or different ways of showing affection.
Understanding these differences through diagnosis helps you support your child authentically rather than trying to push them into a different mold.
Early diagnosis (18 months to 3 years) gives access to Part C early intervention services in North Carolina, which provides free or low-cost therapy in your home. This can significantly benefit development during highly plastic brain years.
School-age diagnosis (3-5 years) opens access to special education services and accommodations in preschool or kindergarten.
Later diagnosis (elementary age and beyond) still provides value. Understanding your child’s autism helps families make better choices about school placement, accommodations, and support. Therapy like ABA helps at any age.
Diagnosis at any age is valuable. It explains your child’s experience, guides support, and connects you to resources.
Evaluation costs money. Here’s how to navigate coverage:
If your family qualifies for NC Medicaid based on income, evaluation is covered. Coverage includes the assessment, testing, and report writing.
To access:
1. Confirm your family’s Medicaid eligibility
2. Ask your pediatrician to refer to a Medicaid-accepting provider
3. Call the provider to schedule; they’ll verify coverage before your appointment
4. Attend the evaluation; you may have a copay depending on your plan
Note: Some Medicaid plans require prior authorization. Confirm with your plan before the evaluation date.
Most commercial insurance plans cover developmental and psychological evaluations. Contact your insurance to ask about coverage for “autism evaluation” or “developmental assessment.” Ask specifically:
If you’re uninsured or insurance doesn’t cover evaluation, many Chapel Hill area providers offer sliding scale fees. Cost shouldn’t prevent you from seeking evaluation; most providers can work with families.
A diagnosis opens doors. After receiving your diagnosis, several options typically become available:
Early Intervention (Birth to Age 3)
Contact the NC Division of Public Health to access Part C services. Your child becomes eligible for free or low-cost speech therapy, occupational therapy, physical therapy, or developmental coaching.
School Services (Age 3+)
Your child qualifies for special education evaluation and services through the school system. You’ll participate in developing an IEP (Individualized Education Plan).
ABA Therapy
Applied Behavior Analysis is the most evidence-based intervention for autism. Visit our ABA therapy services page to learn more. It helps children develop communication skills, social skills, self-care abilities, and learning skills. Many families benefit from in-home ABA services through providers like Children’s ABA North Carolina.
Speech and Occupational Therapy
Most children with autism diagnosis benefit from these therapies, often in combination with ABA.
Family Support and Training
Parents learning autism-friendly strategies makes an enormous difference. Many therapy programs include parent coaching.
Getting Started:
Community Resources:
Once your child has a diagnosis, evidence-based intervention becomes available. ABA therapy is the most researched approach for autism. When delivered in-home through providers like Children’s ABA North Carolina, therapy integrates into your family’s daily routine. Your child learns skills in the settings where they need them, and parents learn strategies to support skill development.
The combination of diagnosis, school services, therapy, and informed parenting creates the foundation for your child to thrive.
