What to Expect During an Autism Evaluation

Scheduling an autism evaluation can bring a mix of emotions for parents. You might wonder what will happen during the appointment and how your child will respond. Will they need to answer questions at a table? Will the evaluator observe them during play? Understanding the process can help ease your worries.

It's important to note that an autism evaluation is not a single test that results in a pass or fail. There is no blood test or medical scan that can diagnose autism. Instead, professionals gather information about the child's developmental history and behavior to make an informed conclusion.

The evaluation process can vary based on the child's age and specific concerns, but it generally follows these key steps:

Step 1: Identifying Developmental Concerns

An evaluation often begins when a parent, teacher, pediatrician, or therapist notices potential concerns in areas such as:

  • Communication

  • Social interaction

  • Play

  • Repetitive behaviors

  • Sensory sensitivities

  • Routines and transitions

  • Emotional regulation

  • Developmental progress

Some children may be referred for evaluation after an autism screening, which helps determine if further assessment is needed. The American Academy of Pediatrics recommends autism screenings during 18- and 24-month well-child visits and whenever developmental concerns arise.

Step 2: Gathering Background Information

Before the evaluation, parents often fill out questionnaires about their child's development and current functioning. You'll likely be asked about:

  • Pregnancy and birth history

  • Developmental milestones

  • Early language and play

  • Medical history

  • School performance

  • Friendships and social behavior

  • Sensory preferences

  • Routines and reactions to change

  • Attention and behavior

  • Daily living skills

  • Family history

Be honest and specific in your responses. Instead of general statements like "She struggles socially," provide concrete examples, such as, "She wants friends but usually waits for other children to approach her and may walk away when rules change." This level of detail helps evaluators understand your child's unique experiences.

Step 3: Interviewing Parents or Caregivers

The evaluator will conduct a more in-depth interview with a parent or caregiver. Expect questions about when you first noticed differences, how your child communicates their needs, and how they respond to social situations and sensory input. The evaluator may ask specific questions about past behaviors to understand the child's developmental history.

It's okay to admit if you don't remember certain details; school records or input from relatives can help fill in gaps.

Step 4: Observing the Child

During the evaluation, the evaluator will interact with and observe your child. Activities may include:

  • Playing with toys

  • Looking at pictures

  • Telling or creating a story

  • Answering questions

  • Completing puzzles

  • Describing emotions or relationships

  • Participating in conversation

  • Demonstrating imaginative play

  • Responding to changes in an activity

The evaluator will pay attention to how your child initiates and responds to interactions, uses communication, and manages transitions. Remember, the evaluator is not expecting perfect behavior; challenges in engagement can also provide valuable insights.

Step 5: Conducting Additional Testing

Some evaluations may include additional tests beyond autism-specific observations. Depending on the concerns raised, the evaluator might assess:

  • Intellectual abilities

  • Language development

  • Academic skills

  • Attention and executive functioning

  • Memory

  • Motor or sensory functioning

  • Emotional and behavioral functioning

  • Adaptive or daily living skills

Evaluations can be conducted by a single professional or a team that may include various specialists, such as speech-language pathologists or developmental pediatricians. Not every child will require every type of test; the evaluation battery should be tailored to the child's needs.

Step 6: Collecting Information from Other Settings

Children may behave differently in various environments, such as home and school. The evaluator might request:

  • Teacher questionnaires

  • School records

  • Individualized Education Program (IEP) documents

  • Previous testing results

  • Therapy notes

  • Report cards

  • Work samples

Teachers can provide insights into classroom behavior, peer interactions, and learning routines, while parents can share information about communication and sensory needs. Differences in behavior across settings do not imply inaccuracies; rather, they highlight the child's varying support and demands.

Step 7: Reviewing All Information

The evaluator will consider the complete picture rather than relying on isolated behaviors or scores. A child is not diagnosed with autism solely based on avoiding eye contact or engaging in repetitive behaviors. The evaluator will assess whether the child's developmental pattern meets established diagnostic criteria and consider other conditions that may explain the concerns.

Step 8: Results Appointment

After testing, a separate appointment may be scheduled to discuss the results. During this meeting, you can expect to learn:

  • If the child meets criteria for autism

  • If other diagnoses were identified

  • The child's strengths

  • Areas needing support

  • Recommended accommodations

  • Suggested services or follow-up

  • When reevaluation may be appropriate

Don’t hesitate to ask questions if something is unclear. It's normal to feel a mix of emotions during this time.

Step 9: Receiving the Written Report

The written report will summarize the evaluation findings, including background information, observations, test results, and recommendations. Review it carefully for accuracy, ensuring your child's details are correct. If you find any inaccuracies, request corrections, as the report may be used by various professionals in the future.

Preparing Your Child for the Evaluation

When preparing your child, use simple and honest language to explain the process. You might say:

  • “We are meeting someone who wants to learn how you think, communicate, play, and solve problems.”

  • “You may answer questions, look at pictures, or play with some materials.”

  • “You can ask for a break if you need one.”

Avoid pressuring your child to perform well. Bring any necessary items, such as glasses or comfort items, and try to schedule the appointment during a time when your child is typically alert. Arriving early and preparing written questions can also help ease the visit.

What Happens After the Evaluation?

A diagnosis can help families access accommodations, school support, and community services. However, families don’t always need a formal diagnosis to seek assistance. Early intervention services may be available based on demonstrated needs.

The goal of an autism evaluation is not to limit a child but to understand them more fully. A comprehensive evaluation can clarify challenges, highlight strengths, and guide parents toward appropriate supports tailored to their child’s unique needs.
