What happens during an autism evaluation? A step-by-step guide for childcare
If your child has been referred for an autism evaluation, you may have questions about what happens next, what the appointment will involve, and how you can prepare.
An autism evaluation helps specialists understand your child’s communication, social development, behavior, and strengths through conversations, observations, and assessments.
In this guide, you’ll learn what happens at each stage of the evaluation process, from the first parent interview and developmental history review to child observation, standardized assessments, results, and the next steps after the evaluation.
What is an autism evaluation?
An autism evaluation is a comprehensive assessment completed by qualified professionals to understand whether a child shows characteristics associated with autism spectrum disorder (ASD). The evaluation looks at how your child communicates, interacts socially, behaves, learns, and manages everyday activities.
According to the National Institute of Mental Health, autism diagnosis involves looking at a child’s developmental history and behavior because there is no single medical test, such as a blood test or brain scan, that can diagnose autism.
During an autism evaluation process, professionals may gather information about:
Communication skills: how your child understands and uses language, gestures, and other ways of communicating.
Social interaction: how your child responds to others, shares attention, plays, and builds connections.
Behavior patterns: whether your child shows repetitive behaviors, strong routines, or unusual responses to sensory experiences.
Developmental skills: how your child learns, completes daily activities, and develops independence.
The five stages of an autism evaluation process
An autism evaluation involves several stages that help professionals understand your child’s development, communication, behavior, and support needs. The exact process may vary depending on your child’s age, developmental profile, and the provider completing the evaluation.
Each stage provides a different part of the overall picture, from understanding your child’s developmental history to reviewing assessment results and discussing possible next steps.
Stage 1: Parent interview and developmental history
An autism evaluation usually begins with a conversation between you and the provider. During this stage, the clinician learns about your child’s development, communication, behavior, and any concerns you have noticed.
Your observations help the provider understand your child’s everyday experiences, including behaviors and skills that may not appear during a single appointment.
What happens during the clinical interview?
The clinician may ask about:
Early development: when your child reached milestones such as sitting, walking, using gestures, and saying their first words.
Communication skills: how your child expresses needs, understands language, and uses gestures or words.
Social interaction: how your child connects with others, responds to their name, shares interests, and plays.
Behavior patterns: whether your child has repetitive behaviors, strong routines, or difficulty with changes.
Sensory responses: how your child responds to sounds, textures, lights, movement, or other sensory experiences.
Previous concerns and support: feedback from parents, teachers, childcare providers, therapists, or other professionals.
The clinician may also ask about your child’s strengths, interests, and abilities to better understand their overall development.

Why your input matters during the evaluation
Children may behave differently during a clinical appointment than they do at home, school, or in childcare settings. Your observations give the provider important information about your child’s everyday development.
A parent interview helps the clinician understand:
Development over time: how your child’s skills have changed.
Patterns across settings: how your child communicates and behaves in different environments.
Areas where support may help: which skills may benefit from further assessment or intervention.
Once the provider understands your child’s history, the next stage focuses on observing how your child communicates, plays, and interacts during the evaluation.
Stage 2: Behavioral observation during the evaluation
After learning about your child’s developmental history, the provider will observe how your child communicates, interacts, plays, and responds during the evaluation.
The clinician is looking at how your child uses their skills during interaction, not whether they complete activities perfectly.
What clinicians observe
During the observation, the provider may look at:
Communication attempts: how your child uses words, sounds, gestures, or facial expressions to communicate.
Social interaction: how your child responds to others and engages during interaction.
Play skills: how your child explores toys, uses imagination, and participates in shared play.
Response to social cues: how your child responds to their name, questions, or attempts to engage.
Behavior patterns: whether certain routines, movements, or sensory responses appear during the session.
Observation helps clinicians understand how your child’s communication and behavior patterns appear during interaction. Some evaluations may include structured observation tools, such as the Autism Diagnostic Observation Schedule, Second Edition (ADOS-2), which is covered in the next stage.
Stage 3: Autism-specific assessments and standardized testing
After the parent interview and behavioral observation, your child may complete autism-specific assessments that provide clinicians with more structured information about autism-related characteristics.
The tools used depend on your child’s age, communication level, developmental profile, and the provider’s approach. Two assessments you may hear about are the ADOS-2 and ADI-R, which provide different information as part of a broader autism evaluation.
What happens during an ADOS-2 evaluation?
The Autism Diagnostic Observation Schedule, Second Edition (ADOS-2) is a structured assessment where a trained clinician observes your child’s communication, social interaction, play, and behavior.
The activities are adjusted based on your child’s age and communication level. For younger children, the session may involve play-based activities that allow the clinician to observe how your child interacts, communicates, and responds during different situations.
Does the ADOS-2 diagnose autism by itself?
No. An ADOS-2 result is one part of the evaluation process and does not provide a diagnosis on its own.
Clinicians consider ADOS-2 findings alongside your child’s developmental history, caregiver information, behavioral observations, and other assessment results to understand your child’s overall development.
What is the ADI-R?
The Autism Diagnostic Interview-Revised (ADI-R) is a structured caregiver interview that focuses on your child’s developmental history.
It may explore:
Communication development: how your child has used language and other forms of communication over time.
Social interaction: how your child engages with others.
Behavior patterns: repetitive behaviors, routines, and interests.
Using multiple sources of information helps clinicians understand your child’s development more clearly, rather than relying on a single assessment result.
Stage 4: Developmental and functional assessments
After autism-specific assessments, clinicians may include additional developmental assessments to understand your child’s communication, learning, and everyday skills.
The assessments used depend on your child’s age, developmental level, and the concerns being evaluated. Not every child needs every assessment.
Speech-language assessment
A speech-language assessment looks at how your child understands, uses, and applies communication.
It may assess:
Receptive language: how your child understands words, instructions, and conversations.
Expressive language: how your child communicates using words, sounds, gestures, or other methods.
Social communication: how your child uses communication to interact, share interests, and respond to others.
Speech-language professionals also consider how your child communicates during everyday interactions, including gestures, shared attention, and back-and-forth communication.
Cognitive and adaptive assessments
Some evaluations may include assessments of learning abilities and daily functioning.
These may examine:
Cognitive skills: how your child learns, solves problems, and processes information.
Adaptive skills: how your child manages everyday activities, communication, self-care, and routines.
These assessments help clinicians understand your child’s strengths and identify areas where additional support may be helpful.
The specific assessments included may depend on:
Age: different tools are designed for different developmental stages.
Communication level: children may need different approaches based on how they communicate.
Referral concerns: the evaluation may focus on language, behavior, learning, or daily skills.
Once these assessments are complete, the clinician will review the findings and explain the results during the feedback session.
Stage 5: Feedback session and diagnostic report
After all interviews, observations, and assessments are complete, the clinician will review the findings with you and explain the results and next steps.
The feedback session helps you understand your child’s development, strengths, support needs, and whether your child meets the criteria for an autism diagnosis.
What happens during the feedback session?
The provider may discuss:
Evaluation findings: what the assessments and observations show.
Your child’s strengths: skills your child already demonstrates.
Support needs: areas where your child may benefit from help.
Recommendations: possible therapies, services, or next steps.
What is included in an autism evaluation report?
You may receive a written report that includes:
Developmental history: information gathered during the evaluation.
Assessment results: findings from the tools used.
Clinical observations: what the provider noticed.
Diagnostic conclusion: whether your child meets the criteria for autism.
Recommendations: suggested support options.
What happens after the evaluation?
If your child receives an autism diagnosis, the provider may recommend supports based on your child’s needs, such as:
Speech therapy: supporting communication skills.
Occupational therapy: supporting daily activities and independence.
ABA therapy: supporting learning, communication, and behavior goals.
Educational support: helping your child access appropriate school services.
The National Institute of Mental Health explains that autism support can include behavioral, developmental, educational, and communication interventions tailored to each child’s needs.
Even if your child does not receive an autism diagnosis, the evaluation can still provide useful information about communication, learning, behavior, or development and help guide the next steps.

FAQs about the autism evaluation process
1. What happens during an autism evaluation in Miami?
An autism evaluation in Miami involves several steps that help professionals understand your child’s development. The process usually includes a parent interview, a developmental history review, observation of your child’s communication and behavior, standardized assessments, and a feedback session to discuss results and recommendations.
The evaluation looks at areas such as communication, social interaction, behavior patterns, and daily skills rather than relying on one test alone.
2. How long does an autism evaluation take?
The length of an autism evaluation varies depending on your child’s age, the provider, and the type of assessments needed. Some evaluations may be completed in one appointment, while others may involve multiple sessions for interviews, observation, testing, and feedback.
Before scheduling, ask the provider how many appointments are required and when you can expect the results.
3. What should I bring to an autism evaluation?
Before the appointment, gather any information that can help the provider understand your child’s development. This may include previous medical records, therapy reports, school or childcare feedback, developmental notes, and videos showing behaviors you want to discuss.
It can also help to write down your concerns and questions before the evaluation so you do not forget important details during the appointment.
4. Is ADOS-2 required for an autism diagnosis?
ADOS-2 is one tool that may be used during an autism evaluation, but it is not the only part of the process. The ADOS-2 allows trained clinicians to observe communication, social interaction, play, and behavior patterns.
Professionals usually combine ADOS-2 results with developmental history, caregiver information, clinical observations, and other assessments before making a diagnostic decision.
5. Can autism be diagnosed after one evaluation?
A clinician may make an autism diagnosis after a comprehensive evaluation, but the process depends on your child’s age, development, and the information available to the clinician.
A complete evaluation considers multiple sources of information, including your observations, your child’s behavior during the assessment, developmental history, and standardized assessment results.
6. What questions should I ask before an autism evaluation?
Before booking an evaluation, consider asking:
Who will complete the evaluation?
What type of assessments are included?
Does the provider evaluate children my child’s age?
How long will the process take?
When will I receive the results?
Will I receive a written report?
What support recommendations are provided after the evaluation?
Asking these questions can help you choose a provider that fits your child’s needs and your family’s situation.
7. What is the difference between an autism screening and an autism evaluation?
An autism screening is an initial tool used to identify whether a child may benefit from further assessment. It does not diagnose autism.
An autism evaluation is a more detailed process completed by qualified professionals. It combines information about your child’s development, behavior, communication, and social interaction to determine whether they meet the criteria for an autism diagnosis.
