Functional Behavior Assessment
Before we change a behavior, we need to understand it. A Functional Behavior Assessment is the detective work that uncovers why a behavior is happening — because once we know the 'why,' we can build a plan that actually helps.
A closer look at functional behavior assessment
A Functional Behavior Assessment, or FBA, is the careful process a BCBA uses to figure out the purpose behind a challenging behavior. Every behavior is doing a job for your child — getting attention, escaping a demand, obtaining something they want, or meeting a sensory need. The FBA identifies that function so the support plan targets the real cause, not just the surface.
To do this, your BCBA gathers information from several angles: talking with you and other caregivers, reviewing relevant history, and observing your child to see what tends to happen right before and right after the behavior. Those patterns reveal what's driving it.
The FBA isn't a treatment by itself — it's the foundation. What comes out of it is a clear understanding of the behavior's function, which directly shapes an individualized behavior plan. Skipping this step is like prescribing without a diagnosis; the FBA makes sure the plan is built on real understanding.
Who benefits most
How it actually works
The process begins with conversation. Your BCBA talks with you about the behavior — what it looks like, when it tends to happen, and what's been tried — because your insight as the parent is invaluable.
Next comes observation. Your BCBA watches your child in their natural environment, paying close attention to what happens just before a behavior (the trigger) and just after (the result). At home, that means seeing the behavior in the real context where it occurs, which often surfaces patterns that aren't obvious in the moment.
Once your BCBA has enough information, they pull it together into a clear picture of why the behavior is happening and use it to design an individualized behavior plan. They'll walk you through the findings in plain language and explain the recommended next steps.
How Getting Started Works
From your first phone call to your child's first session — and every step after — here's exactly how it goes.
Talk to a BCBA
Call, text, or fill out the form. A real person picks up, and a BCBA calls you back for an honest conversation about your child — no scripts, no sales pitch.
In-Home Assessment
Your BCBA meets your child where they're comfortable — at home — to understand their strengths, their challenges, and what matters most to your family.
We Verify Your Insurance
We call your insurance, confirm your benefits, and tell you exactly what's covered before anything starts. Most Iowa families pay little or nothing. Zero surprises.
Therapy Starts at Home
We match your child with the therapist who's the right fit and build a plan around their goals. Sessions start in the comfort of your home, on your schedule.
Progress You Can See
Your BCBA tracks every goal and reviews the data with you regularly. You'll always know what's working, what's next, and how far your child has come.
We Stick With You
As your child grows, we adjust the plan, keep coaching you, and stay just a text away. This is a long-haul partnership — not a drop-off and goodbye.
Questions About Functional Behavior Assessment
Straight answers. If yours isn't here, just call or text us.
No. An FBA doesn't diagnose autism or any condition — it's an assessment of a specific behavior to understand why it's happening. A diagnosis comes from a qualified medical or psychological professional. An FBA assumes we're looking at a particular behavior and works to identify its function so we can support your child effectively.
It varies depending on the behavior and how often it occurs, since your BCBA needs enough observations to spot reliable patterns. Some assessments come together fairly quickly, while others take longer. Your BCBA will give you a realistic sense of the timeline up front.
The findings become the blueprint for an individualized behavior plan. That plan typically focuses on teaching new skills and replacement behaviors that meet the same need in a healthier way. Your BCBA reviews everything with you and explains the recommended next steps before any plan is put in place.
Yes. As a foundational part of ABA services, an FBA is typically covered by Wellmark Blue Cross Blue Shield and other commercial plans, with Iowa Medicaid coming soon. We verify your benefits before beginning the assessment.
