Step 1: Recognizing Early Signs and Starting the Conversation
Parents and caregivers are often the first to notice developmental differences. Common early signs of autism may include limited eye contact, delayed speech, repetitive behaviors, or difficulty with social interactions. If you have concerns, start by talking to your child's pediatrician. They can perform a developmental screening using tools like the M-CHAT (Modified Checklist for Autism in Toddlers) during well-child visits. The American Academy of Pediatrics recommends autism-specific screening at 18 and 24 months.
What to do if your pediatrician dismisses concerns
If you feel your concerns are not taken seriously, trust your instincts. You can request a referral to a specialist directly, or seek a second opinion. In New Jersey, you can also contact your local early intervention program or school district for an independent evaluation.
Step 2: Getting a Comprehensive Diagnostic Evaluation
A formal autism diagnosis requires a comprehensive evaluation by a qualified professional. This typically includes a detailed developmental history, observation of your child, and standardized assessments like the ADOS-2 (Autism Diagnostic Observation Schedule).
Who can diagnose autism in New Jersey?
In New Jersey, the following professionals can provide a medical diagnosis of autism:
- Developmental pediatricians - specialize in child development and autism.
- Child psychologists or neuropsychologists - conduct cognitive and behavioral assessments.
- Child psychiatrists - can diagnose and manage co-occurring conditions.
- Neurologists - may also evaluate for autism and related neurological conditions.
Your pediatrician can provide referrals, or you can search for providers through organizations like Autism New Jersey or the New Jersey Chapter of the American Academy of Pediatrics.

Step 3: Options for Children Under 3 - Early Intervention
New Jersey's Early Intervention System (NJ EIS) provides free evaluations for children under 3 who may have developmental delays. If your child qualifies, they can receive services like speech therapy, occupational therapy, and ABA at no cost to your family, regardless of income. Contact your local regional early intervention collaborative to request an evaluation. You do not need a doctor's referral.
Step 4: Options for Children 3 and Older - School District Evaluations
For children aged 3 to 21, public school districts in New Jersey are required to provide a free evaluation if there is a suspected disability, including autism. This is part of the Individuals with Disabilities Education Act (IDEA). You can request an evaluation in writing to your school district's child study team. The evaluation may include psychological, educational, and speech-language assessments. If your child is found eligible, they can receive an Individualized Education Program (IEP) with tailored supports and therapies.

Step 5: Private Evaluations and Insurance Coverage
Many families choose private evaluations for faster access or more comprehensive assessments. In New Jersey, most health insurance plans, including Medicaid (NJ FamilyCare), are required to cover diagnostic evaluations for autism under the state's autism insurance mandate. This law, effective since 2009, mandates coverage for the diagnosis and treatment of autism spectrum disorder.
Costs and what to expect
Without insurance, a private evaluation can cost between $1,500 and $5,000. With insurance, out-of-pocket costs depend on your plan's deductible and copay. Always check with your provider and insurance company before scheduling. Some hospitals and clinics offer sliding scale fees or payment plans.
What Happens After a Diagnosis?
Once your child receives an autism diagnosis, you can begin accessing therapies and supports. ABA therapy is one of the most evidence-based interventions for autism and is often covered by insurance.
