When you’re choosing an ABA program for your child, one of the most important things you can understand is who, exactly, will be working with them — and what qualifications those people have. ABA therapy is delivered by a team, not a single clinician, and the roles within that team are distinct. Knowing what a BCBA does versus what an RBT does, what “supervision” looks like in practice, and what credentials to verify gives you a much stronger foundation for evaluating any program you’re considering.

This guide explains the credential structure you’ll encounter in ABA therapy and what each role looks like day to day. It’s written for parents, not clinicians.

The Two Core Roles in ABA Therapy

Most ABA programs involve two primary roles: the Board Certified Behavior Analyst (BCBA) and the Registered Behavior Technician (RBT). Understanding the distinction between them is fundamental to understanding how the therapy works.

What a BCBA Does for Your Child

A Board Certified Behavior Analyst is a master’s-level clinician who has completed graduate-level coursework in behavior analysis, accumulated a required number of supervised fieldwork hours, and passed the national BCBA certification examination administered by the Behavior Analyst Certification Board (BACB). For a parent-friendly overview of how BCBAs and RBTs work together within an ABA therapy program, our guide for Utah families covers the full picture. BCBAs are also required to maintain their certification through ongoing continuing education.

In an ABA program, the BCBA is the clinical lead. They are responsible for:

  • Conducting the initial behavior assessment and any reassessments throughout the program
  • Designing the individualized treatment plan, including specific goals and teaching strategies
  • Determining the recommended number of therapy hours per week
  • Supervising the RBTs who deliver direct therapy
  • Reviewing session data and adjusting the treatment plan based on what the data shows
  • Communicating progress to families and providing parent training

The BCBA is also responsible for completing Functional Behavior Assessments when a child has significant challenging behaviors, and for developing Behavior Support Plans that the whole team implements consistently.

What the BCBA typically does not do is deliver most of the direct, hour-by-hour therapy. That’s the RBT’s role. The BCBA is the designer and supervisor of the program — the person making the clinical decisions behind the scenes and ensuring the program is working.

What an RBT Does With Your Child

A Registered Behavior Technician is the person your child will spend the most time with in therapy. RBTs complete a required training curriculum, pass a competency assessment, and obtain certification through the BACB. They work entirely under the supervision of a BCBA and cannot modify goals or strategies on their own.

In sessions, the RBT implements the teaching strategies outlined in your child’s treatment plan. They deliver the structured teaching trials, facilitate natural environment learning, collect data on your child’s performance throughout each session, and build the therapeutic relationship that makes learning possible. A good RBT is warm, patient, creative, and skilled at reading what a child needs in a given moment — including when to push gently forward and when to back off and rebuild motivation.

RBTs may not have master’s-level training, but they operate within a clinical framework designed and supervised by someone who does. The quality of that supervision is what makes the difference.

What “Supervision” Actually Means

In ABA, the BACB sets specific requirements for how much supervision an RBT must receive and what that supervision must include. Supervision isn’t just a check-in call once a month. It includes direct observation of sessions, review of the data the RBT has collected, feedback on implementation, and ongoing training on the treatment plan as goals change.

When you’re evaluating a provider, it’s worth asking specifically how supervision is structured. Questions like “How often does the BCBA observe my child’s sessions?” and “How does the BCBA communicate feedback to the RBT?” give you a real sense of whether the clinical oversight is meaningful. Our post on what to look for in an ABA provider lists the questions Utah parents should ask before enrolling. A program where the BCBA reviews data weekly and observes directly at least several times per month is operating very differently from one where supervision is minimal and documentation-only.

Other Credentials You May Encounter

Some ABA programs also employ BCaBAs (Board Certified assistant Behavior Analysts). A BCaBA has bachelor’s-level training and works under BCBA supervision. Day to day, a BCaBA runs more complex teaching protocols and supports RBTs on the floor — bringing more clinical background than an RBT, but not independently designing treatment plans or supervising other staff. You may also see the title “behavior therapist” or “behavior technician” — these often refer to staff who are working toward RBT certification or who hold equivalent state credentials.

In Utah, ABA therapy is subject to state licensure requirements in addition to national certification. Licensed Behavior Analyst (LBA) is the Utah state license that corresponds to the BCBA credential. You can verify licensure status through the Utah Division of Occupational and Professional Licensing.

Questions to Ask Any ABA Provider

Before enrolling your child in any ABA program, these are reasonable questions to ask — and a quality provider should answer them willingly and clearly:

  • Is your clinical team BCBA-certified and Utah-licensed? Ask to confirm both national certification and state licensure.
  • How often will the BCBA directly observe my child’s sessions? More frequent observation generally means better-calibrated therapy.
  • How will I receive progress updates? Regular parent meetings with the BCBA, not just informal reports, are a sign of a well-structured program.
  • What is the staff-to-child ratio during sessions? Most center-based programs deliver the majority of ABA therapy one-on-one or in very small groups.
  • How long has the BCBA overseeing my child’s case been working in ABA? Experience matters, particularly for complex cases.
  • What happens if my child’s RBT leaves the program? Turnover is a reality in any field; knowing how transitions are handled protects your child’s progress.

How Autism Centers of Utah Structures Its Team

At Autism Centers of Utah, each child’s program is overseen by a BCBA who conducts the initial assessment, develops the treatment plan, and provides ongoing supervision and data review throughout the child’s enrollment. Direct therapy is delivered by RBTs who are trained specifically on each child’s plan and who work under consistent BCBA oversight.

The BCBAs at Autism Centers of Utah also coordinate with our Speech Therapists, Occupational Therapists, and Feeding Therapist — because all of these clinicians work within the same center. When a Speech Therapist identifies that a child is making progress with a new communication strategy, the BCBA hears about it directly and can reinforce that strategy across ABA sessions the same week. That kind of coordination requires proximity, and our Sandy facility was designed to make it possible.

Parent training is also a deliberate part of the program. Your child’s BCBA will meet with you regularly to review data, explain how the plan is evolving, and give you specific strategies to use at home. You shouldn’t feel like you need to decode what’s happening in sessions — understanding your child’s program should be part of the service you receive.
