Registered Behavior Technicians (RBTs) are authorized to collect data, implement skill acquisition plans, carry out behavior reduction procedures, conduct preference assessments, and assist with functional assessments. All of these tasks must be performed under the supervision of a board-certified behavior analyst (BCBA or BCaBA). The RBT role is hands-on and direct, but it does not include designing treatment plans, interpreting assessment results, or making independent clinical decisions.
If you’re preparing for the RBT exam or clarifying your scope of practice, here’s a detailed breakdown of what RBTs can and cannot do.
Data Collection and Measurement
Data collection is one of the most fundamental RBT responsibilities. Every session, you’ll record information about your client’s target behaviors and skill progress. The RBT Task List (2nd edition) identifies two categories of measurement you need to know: continuous and discontinuous.
Continuous measurement means recording every single occurrence of a behavior. This includes counting how many times a behavior happens (frequency), how long it lasts (duration), how quickly someone responds after an instruction (response latency), and how much time passes between two consecutive responses (interresponse time). You’ll use these methods when it’s practical to observe the behavior from start to finish.
Discontinuous measurement is used when tracking every occurrence isn’t feasible. Instead, you break an observation period into equal intervals and sample the behavior. In whole interval recording, you note whether the behavior occurred throughout the entire interval. In partial interval recording, you note whether it occurred at any point during the interval. Momentary time sampling checks whether the behavior is happening at the exact moment an interval ends.
Beyond raw data collection, RBTs are also responsible for entering data into tracking systems and updating graphs. This documentation is what supervisors rely on to evaluate whether a treatment plan is working.
Assessment Tasks
RBTs have a limited but important role in assessments. You can independently conduct preference assessments, which involve presenting items or activities to identify what a client finds most motivating. These results help determine which reinforcers to use during sessions.
You can also assist with individualized assessment procedures, including curriculum-based, developmental, and social skills assessments. The key word is “assist.” Your supervisor designs the assessment and tells you what to do; you carry out the specific steps and record the results. The same applies to functional assessment procedures, where you might collect ABC data (antecedent, behavior, consequence) to help identify why a challenging behavior is occurring. You collect and report, but you don’t analyze the data or draw clinical conclusions.
Skill Acquisition Procedures
A large portion of an RBT’s daily work involves teaching new skills by following a plan written by a BCBA. The specific teaching methods you’re expected to implement include:
- Discrete-trial teaching: structured, repeated trials with a clear instruction, response, and consequence
- Naturalistic teaching: using naturally occurring opportunities, like a child reaching for a toy, to practice communication or social skills
- Chaining: breaking a complex task into smaller steps and teaching them in sequence (forward or backward)
- Shaping: reinforcing closer and closer approximations of a target behavior until the full behavior is achieved
- Discrimination training: teaching a client to respond differently to different stimuli
- Stimulus control transfer: shifting a behavior from one type of prompt or cue to another
Within all of these, you’ll use prompting strategies that range from full physical guidance to simple verbal cues. The plan will specify how to fade prompts over time so the client becomes more independent. You’ll also follow error correction procedures, which outline exactly how to respond when a client makes a mistake, typically by re-presenting the instruction with additional support.
Token systems are another tool in your skill acquisition toolkit. These involve delivering tokens (stickers, points, check marks) that clients exchange for preferred items or activities later. You implement the system as your supervisor designed it.
Behavior Reduction Procedures
RBTs implement behavior reduction strategies, but only those that have been documented in a behavior plan and approved by a supervisor. You do not decide which strategies to use on your own.
Common approaches you may carry out include antecedent interventions, which modify the environment before a problem behavior occurs. This could mean offering choices, adjusting task difficulty, providing visual schedules, or delivering preferred items on a fixed schedule (non-contingent reinforcement) to reduce the motivation for challenging behavior. For a client who engages in escape-motivated behavior, for example, you might present easier tasks first or use visual supports to make expectations clearer.
You may also implement differential reinforcement, which means providing reinforcement for desired behaviors while withholding it for problem behaviors. One version reinforces a specific alternative behavior (like raising a hand instead of yelling). Another reinforces the absence of the problem behavior for a set period of time.
Extinction procedures, where the reinforcement that previously maintained a problem behavior is no longer provided, are also within your scope. These must always be paired with reinforcement for replacement skills. Restrictive or punishment-based procedures can only be implemented when they are explicitly included in a documented plan and your supervisor has confirmed you’re competent to carry them out.
Documentation and Session Notes
After each session, RBTs generate objective session notes describing what happened. These notes should focus on observable events: what was targeted, how the client responded, and any notable behaviors. The emphasis is on objectivity. You describe what you saw, not your interpretation of why it happened.
Crisis and Emergency Procedures
RBTs are expected to implement crisis and emergency procedures according to established protocols. This means following a pre-determined plan when a client’s behavior poses an immediate safety risk. You don’t create these protocols, but you need to know them thoroughly and execute them correctly.
Professionalism and Ethical Conduct
Maintaining client dignity and professional boundaries is an explicit part of the RBT role. You’re expected to treat clients with respect, protect their privacy, and keep your relationship with clients and their families within professional limits. When questions or concerns arise, whether from you, caregivers, or coworkers, your responsibility is to direct them to your supervisor rather than attempting to address clinical issues independently.
What RBTs Cannot Do
The boundary between RBT and BCBA responsibilities is clear. RBTs do not design behavior intervention plans, select assessment tools, interpret assessment data, or make clinical recommendations. You don’t modify a treatment plan based on your own judgment. If something isn’t working, you report it to your supervisor and continue following the existing plan until it’s formally changed.
RBTs also cannot supervise other RBTs, conduct independent assessments, or provide services outside the scope defined by their supervisor. Every task you perform falls under the clinical responsibility of your supervising BCBA.
Supervision Requirements
To practice, RBTs must receive ongoing supervision. At least 5% of your total service-delivery hours must be supervised. Each supervision period requires a minimum of two face-to-face, real-time meetings with your supervisor, and at least one of those must be a one-on-one meeting with no other RBTs present. Your supervisor must also observe you providing direct services to a client in real time at least once per supervision period.
To maintain certification, you complete a recertification competency assessment covering all 20 task items in the RBT Task List. Three of the skill acquisition and behavior reduction tasks must be demonstrated live with a client. This annual process ensures you stay proficient in the core duties you’re authorized to perform.
