The Registered Behavior Technician (RBT) credential is an entry-level certification administered by the Behavior Analyst Certification Board (BACB). It validates that practitioners can implement behavior-analytic services under the close, ongoing supervision of a Board Certified Behavior Analyst (BCBA) or Board Certified Assistant Behavior Analyst (BCaBA). Behavior technicians work in schools, clinics, homes, and community settings to deliver applied behavior analysis (ABA) therapy to individuals — most commonly children diagnosed with autism spectrum disorder, though the credential applies across populations and settings.
The RBT examination consists of 75 multiple-choice questions completed within a 90-minute time limit. Candidates sit for the exam at a Pearson VUE testing center and must pass with approximately a 68% correct rate, though the BACB uses a scaled scoring model and does not publish a fixed cut score publicly. The exam fee is $50 USD and candidates must complete a 40-hour training program and pass a competency assessment before they are eligible to apply.
Questions are drawn from the official RBT Task List (2nd Edition), which covers six domain areas: Measurement, Skill Acquisition, Behavior Reduction, Documentation and Reporting, Professional Conduct and Scope of Practice, and Supporting Assessment and Ongoing Evaluation. Each domain carries a different weight on the exam, so targeted preparation by task list area is the most efficient study strategy.
Practicing with a downloadable PDF gives you the flexibility to study offline, annotate questions by domain, and time yourself under realistic conditions without needing an internet connection. The PDF below mirrors the official exam format and covers all six task list areas with rationale-based answer keys so you understand why each answer is correct — not just which letter to choose.
The BACB RBT Task List (2nd Edition) organizes exam content into six domains. Understanding the weight of each area helps you prioritize your study time effectively.
Measurement is foundational to ABA because data-driven decision making separates the field from intuition-based approaches. The exam tests your ability to distinguish continuous recording methods — which capture every occurrence of a behavior (frequency/event recording, duration recording, latency recording, inter-response time) — from discontinuous recording methods such as partial-interval, whole-interval, and momentary time sampling, which estimate behavior rather than measuring it precisely. You'll also need to understand interobserver agreement (IOA) formulas including exact agreement, partial agreement, total agreement, and trial-by-trial IOA, and know when each is appropriate. Behavioral data is typically graphed on equal-interval or semilogarithmic (Standard Celeration Chart) graphs, and RBTs must be able to collect, record, and graph data accurately before handing it to a supervisor for interpretation.
Skill Acquisition carries the largest exam weight at 40%, reflecting how much of an RBT's direct work involves teaching new skills. Core techniques include Discrete Trial Training (DTT), a structured, massed-trial format that uses a clear antecedent, a prompted or unprompted learner response, and a consequence (reinforcement or error correction). Natural Environment Teaching (NET) embeds learning opportunities in the learner's natural activities and motivation, making it more generalized but harder to systematize. RBTs must master the prompting hierarchy — physical, model, gestural, positional, and verbal prompts from most to least intrusive — and implement prompt fading strategies (most-to-least, least-to-most, time delay, graduated guidance) to build independent responding without prompt dependency. Shaping involves reinforcing successive approximations toward a target behavior, while chaining links a sequence of discrete behaviors into a fluent chain using forward chaining, backward chaining, or total task presentation.
Before intervening on problem behavior, RBTs must understand its function. The four functions — often remembered by the acronym SEAT (Sensory/Automatic, Escape, Attention, Tangible/Access) — explain why a behavior is maintained. Functional Behavior Assessments (FBAs) are conducted by BCBAs; RBTs implement the resulting behavior intervention plans. Key reduction procedures include extinction (withholding the maintaining consequence, which may produce an extinction burst before behavior reduces) and the differential reinforcement procedures: DRA (reinforcing an alternative behavior while placing the problem behavior on extinction), DRO (reinforcing the absence of the target behavior for a set interval), and DRI (reinforcing a behavior physically incompatible with the problem behavior). Antecedent interventions — modifying the environment or establishing operations before behavior occurs — include non-contingent reinforcement (NCR), environmental modifications, and pre-session satiation.
Accurate documentation is both an ethical requirement and a clinical necessity. RBTs write session notes using structured formats such as SOAP notes (Subjective, Objective, Assessment, Plan) or ABC (Antecedent-Behavior-Consequence) data sheets. They are responsible for correctly graphing data across sessions, identifying trends (accelerating, decelerating, variable, or flat/plateaued), and reporting unusual events — including safety incidents, suspected abuse or neglect, and significant behavior changes — to their supervisor promptly. Documentation must be completed within the timeframe required by agency policy and should never be falsified or backdated.
The BACB Ethics Code governs all credential holders. RBTs must work within their scope of practice — they implement BCPs designed by BCBAs and do not independently design, modify, or terminate behavior programs. Key ethics topics include avoiding dual relationships (personal relationships with clients or families outside the professional role), maintaining confidentiality under HIPAA, protecting client dignity, and responding appropriately to boundary violations. The supervisory relationship is central: RBTs must receive ongoing supervision (minimum 5% of service hours per month), document supervision contacts, and actively participate in performance feedback meetings. Misrepresenting credentials, billing for services not rendered, and using non-evidence-based procedures all constitute ethics violations.
Although BCBAs conduct formal functional assessments, RBTs often assist with and conduct preference assessments to identify reinforcers. Common formats include the Multiple Stimulus Without Replacement (MSWO) assessment — in which multiple items are presented simultaneously and each chosen item is removed until all options are depleted — and paired choice (forced-choice) assessments, in which two items are presented at a time and the learner consistently selects higher-preference items. RBTs also help monitor treatment integrity (are procedures being implemented as written?) and assist BCBAs in collecting skill probes and generalization data to inform ongoing program modifications.
The BACB issues three primary behavior analysis credentials that represent a clear progression of training, responsibility, and scope of practice.
The RBT (Registered Behavior Technician) is an entry-level credential requiring a high school diploma (or equivalent), 40 hours of training, a competency assessment, and passing the 75-question exam. RBTs implement behavior-analytic services under close supervision and cannot independently design or modify programs. Annual renewal requires ongoing supervision documentation and a renewal fee.
The BCaBA (Board Certified Assistant Behavior Analyst) requires a bachelor's degree in behavior analysis or a related field, supervised fieldwork hours, and passing the BCaBA examination. BCaBAs can independently provide behavior-analytic services under the supervision of a BCBA, and they may supervise RBTs. The BCaBA credential is less common than the RBT or BCBA and is primarily held by practitioners transitioning toward BCBA certification.
The BCBA (Board Certified Behavior Analyst) is the master's-level credential that functions as the full independent practitioner credential in ABA. BCBAs design behavior intervention plans, conduct functional behavior assessments, provide supervision to RBTs and BCaBAs, and are ultimately accountable for treatment outcomes. A BCBA-D (Doctoral level) designation is available for those holding a doctorate in behavior analysis.
