In the field of applied behavior analysis (ABA), you will often see the qualifications “RBT” and “BCBA.” While both play important roles in behaviour-analytic services, they differ significantly in terms of education, responsibilities, autonomy, and career trajectory.

For those preparing to enter the field or advance their credentials, using an RBT mock exam can be an excellent way to test your knowledge, identify areas for improvement, and build confidence before certification. Understanding these differences is essential if you’re considering entering the field, either as a direct service provider or a supervisor/analyst.

Defining the Roles

What is an RBT?

A Registered Behavior Technician is a credentialed paraprofessional who works under the supervision of a BCBA (or, in some cases, a higher-level behaviour analyst). Their primary function is to provide direct, hands-on services to clients: implementing behaviour intervention plans, collecting data, assisting with skill acquisition and behaviour reduction strategies.

What is a BCBA?

A Board Certified Behavior Analyst is a practitioner who has completed graduate-level education, supervised experience, and a certification examination. BCBAs are qualified to conduct assessments, design behaviour intervention plans, supervise RBTs, track outcomes, and make clinical decisions.

Key Differences: Education and Certification

RBT Pathway

• Minimum educational requirement is a high school diploma or equivalent.
• Completion of a 40-hour training program covering core ABA content (measurement, assessment, skill acquisition, behaviour reduction, documentation and reporting, professional conduct & scope of practice) is required.
• Must pass a competency assessment and exam to become certified.
• Must work under supervision of a qualified BCBA and cannot practice independently.
  

BCBA Pathway

• Usually requires a master’s degree (or higher) in behaviour analysis, psychology, education or a related field.
• Requires completion of supervised fieldwork hours (the number varies depending on changes in standards) and passing the BCBA certification exam.
• Can practice independently (in the sense of designing behaviour plans and taking accountability) and supervise RBTs.
  

Key Differences: Scope of Practice & Responsibilities

RBT

The RBT’s primary work is direct implementation. They:

• Carry out the behaviour intervention plans (BIPs) developed by BCBAs.
• Collect and record data on client progress, behaviour occurrences, skill acquisition.
• Are supervised regularly (often both in‐person and via data review) by a BCBA for quality and fidelity.
• Do not independently evaluate or design intervention plans.
  

BCBA

The BCBA’s responsibilities are broader and include:

• Conducting behavioural assessments (e.g., functional behaviour assessments) to identify key issues and triggers.
• Designing, modifying and overseeing treatment plans and interventions tailored to individual clients.
  
• Supervising RBTs (and sometimes BCaBAs) to ensure proper implementation and data integrity.
• Collaborating with families, educators, other professionals to ensure generalisation of skills and meaningful outcomes.
  

Career & Salary Outlook

Because the roles differ so markedly in responsibility, they also differ in salary and career trajectory.

• RBTs are often entry-level, providing direct care and gaining experience.
• BCBAs have higher earning potential, more autonomy, and often fill leadership, supervisory or consulting roles.
• For many, working as an RBT can be a stepping stone toward pursuing BCBA certification.

Which Path is Right For You?

Deciding whether to become an RBT or a BCBA depends on several factors:

1. Education & Time Commitment

• If you want to enter the field relatively quickly and begin working with clients, the RBT path is faster and less academically intensive.
• If you are willing to invest in graduate education and want to take on more leadership, design and supervisory responsibilities, the BCBA path may be preferable.

2. Desired Role & Responsibilities

• Do you enjoy hands-on work, interacting directly with clients, doing the day-to-day therapy? Then RBT may suit you.
• Do you want to evaluate programs, craft interventions, supervise others, influence strategy and outcomes at a higher level? Then BCBA may be your goal.

3. Career Progression

• Some start as RBTs to gain experience, then progress to BCBA. This pathway gives practical exposure to the field before committing to advanced training.
• Some remain RBTs if they prefer the direct service role and are satisfied with that level.

4. Financial Consideration

• The upfront cost (education, exams) and ongoing responsibilities of a BCBA are greater.
• However, the potential long-term salary and professional scope are significantly higher.

Preparing for the RBT Role: How to Get Started

If you choose to pursue the RBT credential, these are the key steps:

• Complete the required 40-hour training in the core content areas (measurement, assessment, skill acquisition, behaviour‐reduction, documentation & professional conduct).
• Undergo a competency assessment supervised by a qualified behaviour analyst.
• Pass the RBT exam (administered by the Behavior Analyst Certification Board (BACB)).
• Maintain certification via ongoing supervision, renewal, and adherence to the RBT code of ethics.

One helpful resource is the RBT mock exam available from Behavior Prep. Taking a mock exam gives you a realistic preview of the format, types of questions, and level of understanding required. It’s a smart way to check your readiness and refine your study strategy.
