What Happens During an ABA Assessment?

An ABA assessment helps a Board Certified Behavior Analyst (BCBA) understand your child’s strengths, needs, interests, and everyday routines. It provides a starting point for an individualized treatment plan. It isn’t a test your child needs to pass, and you don’t need to practice answers beforehand.

First, we listen to your family

The BCBA asks about what is going well, what feels difficult, and which changes would make daily life easier. You can share concerns about communication, play, daily routines, or behaviors that affect safety.

Your priorities matter. For example, you might want help with asking for a break, getting ready for school, or participating in family activities.

Interviews and observation

We talk with parents and caregivers about your child’s strengths, communication, routines, and challenges. We also observe play, learning, and everyday activities to understand what support may be helpful.

Interests and preferences

We may use a preference survey and offer choices to learn which toys, activities, and interactions your child enjoys—or prefers to avoid. This helps us personalize sessions and identify possible reinforcers: things that can help strengthen useful skills.

Preferences can change, so we keep checking what is meaningful to your child.

Understanding patterns with ABC data

When needed, we record what happens before a behavior, the behavior itself, and what happens afterward. This is called antecedent–behavior–consequence, or ABC, data. It helps us identify patterns rather than guess why a behavior happens.

Understanding why a behavior happens

When a closer look at a behavior is needed, we conduct a functional behavior assessment (FBA). This brings together information from interviews, observation, and ABC data to identify what may be maintaining the behavior and guide support.

A functional analysis (FA) is a specific assessment method that may be used as part of an FBA. A qualified clinician carefully changes specific conditions and measures how behavior responds to test possible explanations.

Not every FBA requires an FA. Before proceeding, the BCBA explains the process, discusses risks and safeguards, and obtains informed consent.

What should you prepare?

Ask the intake team which documents are needed. Helpful information may include:

• Previous evaluations or reports, if available.
• Examples of routines that are easy or difficult.
• Your child’s interests and preferred ways to communicate.
• Questions you want the BCBA to answer.

Tell the team about communication supports, sensory preferences, or breaks that help your child feel comfortable.

What happens afterward?

The findings help guide proposed goals, recommendations, and ways to measure progress. An ABA treatment assessment serves a different purpose from an evaluation used to diagnose autism.

Before starting, ask:

• Why are these goals being recommended?
• How will my child’s preferences be included?
• How will we know whether the plan is helping?
