Understanding the Autism Diagnosis Process

A BCBA's Guide for Parents

If you’re reading this, you may be at the beginning of a journey you didn’t expect — noticing differences in your child’s development, hearing concerns from a teacher or pediatrician, or simply trusting your gut that something seems “off.” As a Board Certified Behavior Analyst (BCBA) who works closely with families, I want you to know: you’re not alone, and there is a path forward.

What Is Autism Spectrum Disorder (ASD)?

Autism Spectrum Disorder (ASD) is a neurodevelopmental condition that affects social communication, behavior, and how individuals process the world around them. It is called a "spectrum" because every individual with autism presents differently — from children who are minimally verbal and need significant support, to those who are highly verbal with more subtle social difficulties.

Early Signs to Look Out For

You might notice some of the following early signs in your child:

• Limited eye contact or facial expressions

• Delayed speech or language skills

• Repetitive behaviors (e.g., hand flapping, lining up toys)

• Difficulty with transitions or changes in routine

• Challenges in playing with peers or engaging in pretend play

If any of these behaviors resonate with you, the next step is to seek a formal evaluation.

The Diagnostic Process

Getting an autism diagnosis can feel overwhelming at first, but knowing what to expect can help ease the stress.

1. Speak With Your Pediatrician

Share your concerns clearly and ask for a referral to a developmental pediatrician, psychologist, or neurologist who specializes in autism evaluations.

2. Developmental Screening

Many pediatricians use a brief questionnaire (like the M-CHAT) during well visits to screen for autism. If concerns persist, a more comprehensive evaluation will be recommended.

3. Comprehensive Evaluation

This is typically conducted by a licensed psychologist, developmental pediatrician, or a team of professionals. The evaluation may include:

• Direct observation of your child

• Parent interviews

• Standardized assessments such as the ADOS-2 (Autism Diagnostic Observation Schedule)

• Cognitive and language testing

The goal is to understand your child’s strengths and challenges across multiple areas of development.

After the Diagnosis

Receiving a diagnosis of ASD can bring a wave of emotions — relief, grief, confusion, or even validation. All of these reactions are valid. The important thing to remember is that a diagnosis is not a label meant to limit your child; rather, it is a tool to help unlock appropriate support, services, and therapies.

As a BCBA, my role often begins after the diagnosis. I collaborate with families to help develop skill-building, communication, independence, and reducing barriers to learning.

Why Early Diagnosis Matters

Early identification and intervention lead to better long-term outcomes. The earlier we can start teaching communication skills, social interactions, and adaptive behaviors, the more we can support your child’s development during the critical early years.
