Who Can Diagnose Autism in Children? A Parent’s Guide to Understanding Your Options
If you are wondering whether your child may have autism, one of the first questions many parents ask is:
“Who can diagnose autism in children?”
You may also be searching:
Who can evaluate my child for autism?
Who provides autism testing?
Should I see a psychologist, developmental pediatrician, or another specialist?
What type of professional can diagnose Autism Spectrum Disorder?
Where can I find an autism evaluator near me?
Finding the right professional for an autism evaluation can feel overwhelming. Understanding who is qualified to diagnose autism—and what to look for in an evaluator—can help you make an informed decision for your child and family.
At Fein Psychology Services in Houston, TX, autism evaluations are provided by Rachel Fein, PhD, BCBA, a licensed Child Psychologist and Board Certified Behavior Analyst with more than 20 years of experience evaluating children, adolescents, and young adults with developmental, behavioral, learning, and social differences.
Who Can Diagnose Autism Spectrum Disorder?
Autism Spectrum Disorder (ASD) can be diagnosed by qualified professionals with specialized training and experience in autism assessment.
Professionals who may diagnose autism include:
Licensed psychologists
Developmental-behavioral pediatricians
Psychiatrists
Pediatric neurologists
Multidisciplinary autism diagnostic teams
The most important factor is not simply the professional’s title. The quality of an autism evaluation depends on the evaluator’s training, experience, and ability to recognize the wide range of ways autism can present.
A knowledgeable autism evaluator should understand that autism can look different across children, including children who:
Have strong language skills
Perform well academically
Appear socially successful at first glance
Have co-occurring ADHD or anxiety
Mask or compensate for social challenges
What Does an Autism Evaluator Do?
An autism evaluator’s role is to gather information from multiple sources to understand your child’s development, communication, behavior, learning profile, and social functioning.
A comprehensive autism evaluation may include:
Parent interviews
Detailed developmental history
Review of school or therapy records
Behavioral observations
Standardized autism assessment tools
Cognitive testing when appropriate
Adaptive functioning measures
Feedback session with recommendations
The goal is not simply to determine whether your child meets criteria for an autism diagnosis.
A high-quality evaluation helps answer:
What are my child’s strengths?
What challenges are they experiencing?
Why might certain behaviors be occurring?
What supports would be most helpful at home, school, and in the community?
Can a Psychologist Diagnose Autism?
Yes. A licensed psychologist with specialized training and experience in autism assessment can diagnose Autism Spectrum Disorder.
Many families choose a psychologist for an autism evaluation because psychologists often provide comprehensive assessments that consider multiple areas of development, including:
Social communication
Play skills and relationships
Behavioral patterns
Cognitive abilities
Learning strengths and challenges
Executive functioning
Emotional regulation
Co-occurring conditions such as ADHD and anxiety
A psychologist-led autism evaluation can provide families with a deeper understanding of their child’s unique profile—not just a diagnosis.
Can a Pediatrician Diagnose Autism?
Some pediatricians, particularly developmental-behavioral pediatricians with specialized training, diagnose autism.
However, many pediatricians refer families for a more comprehensive autism assessment, especially when:
The presentation is subtle
There are multiple developmental or behavioral concerns
ADHD, anxiety, or learning differences may also be present
Additional testing is needed to better understand the child
A comprehensive evaluation can help differentiate autism from other developmental or behavioral concerns and identify whether multiple conditions may be contributing to a child’s experiences.
Who Evaluates Toddlers for Autism?
Toddlers can be evaluated for autism by professionals experienced in early childhood development and autism assessment, including:
Child psychologists
Developmental-behavioral pediatricians
Pediatric neurologists
Multidisciplinary diagnostic teams
Early autism evaluations are valuable because they help families better understand developmental differences and identify supports as early as possible.
For toddlers, evaluators often look closely at:
Language development
Social communication
Joint attention skills
Gestures and nonverbal communication
Play skills
Sensory differences
Repetitive behaviors
At Fein Psychology Services, autism evaluations are available for children as young as 18 months of age.
What Should Parents Look for When Choosing an Autism Evaluator?
Choosing the right autism evaluator is an important decision. Parents may want to consider the following:
Experience With Your Child’s Age. Look for an evaluator who regularly assesses children in your child’s age range. Autism can present differently in toddlers, school-age children, teenagers, and young adults.
Specialized Training in Autism Assessment. Ask about the evaluator’s experience with evidence-based autism assessment tools and current diagnostic practices. A comprehensive autism evaluation may include tools such as:
ADOS-2 (Autism Diagnostic Observation Schedule, Second Edition)
CARS-2 (Childhood Autism Rating Scale, Second Edition)
SRS-2 (Social Responsiveness Scale, Second Edition)
Developmental and adaptive measures
Understanding of Different Autism Presentations. Autism does not look the same in every child. An experienced evaluator should understand differences related to:
Girls and gender differences
High-masking autism
Strong verbal abilities
Giftedness
ADHD and anxiety
Different developmental profiles
A Comprehensive Approach. A strong autism assessment does not rely on a single test. Instead, diagnosis should be based on multiple sources of information, including:
Parent input
Developmental history
Direct observation
Standardized assessment results
Clinical judgment

Frequently Asked Questions About Autism Diagnosis
Can autism be diagnosed with one test?
No. Autism cannot be diagnosed based on a single test score or observation.
A diagnosis is based on a comprehensive autism evaluation that combines developmental history, parent input, behavioral observations, and standardized assessment information.
Is an autism diagnosis only for young children?
No. Autism can be identified in toddlers, children, adolescents, and adults.
Some individuals are diagnosed later because their differences are less noticeable, they have strong verbal skills, or they have developed strategies to compensate for challenges.
Can autism and ADHD be diagnosed together?
Yes. Autism and ADHD commonly occur together.
A comprehensive evaluation can help determine whether a child meets criteria for autism, ADHD, both conditions, or another explanation for their challenges.
