Understanding the "ABA Job": A Parent’s Tactical Guide to the Therapy Team
If you’ve recently started looking into autism services, you’ve likely been hit with a wave of acronyms: BCBA, RBT, BT, Case Manager. It feels like you’re trying to hire for a corporate department you didn’t know you owned.
At Tellos, we know you don’t have time for an HR seminar. You need to know who is coming into your house, what their "job" actually is, and how ABA therapy works in practice so you can ensure your child is receiving the highest quality care. Here is your straightforward, tactical breakdown of the roles within a high-quality ABA team in 2026.
The Chain of Command: Who Does What?
An ABA team is structured like a construction project. You have the architect who draws the plans and the builders who lay the bricks. Both are essential, but their "ABA jobs" are very different.
1. The BCBA
The Board Certified Behavior Analyst is the clinical lead. Their job is to look at the big picture.
What they do: Conduct assessments, write the specific goals for your child, and analyze the data to see if progress is happening.
The Tactical Check: In 2026, a BCBA should be in your home or at the clinic supervising the direct therapy at least 10-20% of the time. If you haven't seen your BCBA in a month, that’s a red flag.
2. The RBT or BT
The Registered Behavior Technician or Behavior Technician is the person who works 1-on-1 with your child every day.
What they do: They implement the "plan" created by the BCBA. They are in the trenches, playing, teaching, and managing behaviors in real-time.
The Tactical Check: Since 2025, many states have moved toward a strict "RBT-only" model for insurance. This means the person in your home should have passed a national exam and be under active supervision.
What a "Good Day" at the Job Looks Like
When you’re watching a session, it shouldn't look like a rigid drill. In 2026, the gold standard for an ABA job is Natural Environment Teaching (NET).
If the therapist is doing their job well, it should often look like purposeful play.
Tactical Win: If your child is laughing and engaged while working on communication, the RBT is succeeding.
Red Flag: If the therapist spends more time on their tablet taking data than interacting with your child, it’s time for a "performance review" with your BCBA.
Tactical Checklist: Vetting the Team
When you are interviewing a new provider, don’t just ask if they are "good with kids." Ask these three tactical questions instead:
"What is your RBT turnover rate?" This job is demanding. A center with high turnover means your child will constantly be "starting over" with new faces. Look for centers that invest in their staff.
"How do you handle staff burnout?" You want a therapist who is energized, not exhausted. If the center doesn't have a plan for staff support, your child’s therapy will eventually suffer.
"What does your internal supervision look like?" Ask how often the BCBA observes the RBT. In 2026, the standard is a minimum of 2 hours of supervision for every 20 hours of therapy.
The Most Important Job: Yours
At Tellos, we believe the most successful ABA programs are the ones where the parents act as the "Project Managers." You don't need to do the RBT’s job, but you do need to hold them accountable to the goals you care about.
Focus on Function: Ensure the team is working on skills that make your life easier—like toilet training, transitions, or safety—rather than just "sitting still."
Demand Transparency: You should have access to the data dashboard 24/7. In 2026, there is no excuse for "waiting for the monthly report."
The Bottom Line
Understanding the "ABA job" means knowing that you are the boss of a specialized clinical team. When the BCBA and RBT are aligned, and you are holding the roadmap, progress doesn't just happen—it lasts.
