Preparing for the BCBA (Board Certified Behavior Analyst) certification exam? A printable BCBA practice test PDF gives you an offline format to review behavior analysis principles, experimental design, measurement, behavior change procedures, ethics, and personnel supervision that the BACB BCBA exam assesses. Working through BCBA exam questions on paper deepens your understanding of applied behavior analysis (ABA) science and its clinical application. This page provides a free PDF download and a subject-by-subject BCBA exam preparation guide.
The BCBA credential is issued by the Behavior Analyst Certification Board (BACB) and is the gold standard professional certification for behavior analysts. BCBAs design and oversee ABA programs primarily for individuals with autism spectrum disorder (ASD), developmental disabilities, and behavioral health challenges. The BCBA exam is based on the BACB Task List (5th edition), which organizes behavior analysis knowledge into foundations and applications.
The BCBA exam covers the BACB 5th Edition Task List across foundational and applied domains. Your BCBA practice test PDF covers all major content areas.
Philosophical foundations: behaviorism โ behavior is lawful and determined by environmental events; the three-term contingency (antecedent โ behavior โ consequence) is the fundamental unit of analysis. Basic behavioral concepts: reinforcement (positive reinforcement: adding a stimulus that increases behavior; negative reinforcement: removing a stimulus that increases behavior โ note: both INCREASE behavior), punishment (positive punishment: adding a stimulus that decreases behavior; negative punishment: removing a stimulus that decreases behavior โ both DECREASE behavior), extinction (withholding reinforcement previously maintaining a behavior; extinction burst precedes behavior reduction), stimulus control (discriminative stimuli SD signal that reinforcement is available; Sฮ signals reinforcement is NOT available), schedules of reinforcement (FR, VR, FI, VI โ VR produces highest and most consistent rates; FI produces scallop pattern), and operant vs. respondent conditioning distinctions.
Measurement systems: frequency/rate (count per unit time), duration (total time in behavior), latency (time from antecedent to behavior onset), inter-response time (IRT โ time between responses), percent correct, and trial-by-trial data. Continuous vs. discontinuous measurement (time sampling: whole-interval, partial-interval, momentary time sampling โ each with different accuracy properties). Single-case experimental designs: ABAB reversal design (demonstrates functional relationship by replicating effect), multiple baseline design (across behaviors, settings, or individuals โ used when reversal is impractical or unethical), changing criterion design (behavior shaped to successive criteria), and alternating treatments design (ATD โ compares multiple treatments rapidly). Visual analysis: trend, level, variability, immediacy of effect, overlap โ used to determine behavior change significance without inferential statistics.
Antecedent interventions: SD-based discrimination training, high-probability request sequences (behavioral momentum), non-contingent reinforcement (NCR โ eliminates EO for problem behavior), stimulus fading and shaping procedures. Reinforcement-based procedures: differential reinforcement (DRA โ reinforce alternative behavior; DRI โ reinforce incompatible behavior; DRO โ reinforce absence of behavior; DRL โ reinforce low rates). Punishment procedures: positive punishment (response cost โ removing tokens; overcorrection; contingent exercise), negative punishment (time-out โ removal from reinforcement), sensory extinction. Skill acquisition: discrete trial training (DTT), natural environment teaching (NET), incidental teaching, prompting systems (most-to-least vs. least-to-most prompting), prompt fading (stimulus fading, graduated guidance, time delay), and chaining (forward, backward, total task).
BACB Ethics Code (2022) governs all BCBA practice. Key ethical requirements: prioritize client welfare and autonomy; use the least restrictive effective treatment; obtain informed consent before implementing any behavior change program; maintain accurate and complete data records; avoid dual relationships that could impair professional judgment; report suspected abuse or neglect; maintain competency through continuing education; supervise RBTs and BCaBAs according to BACB supervision standards (5% of RBT monthly hours); never use aversive procedures without exhausting positive alternatives and meeting BACB procedural requirements. BCBAs must complete a required ethics CE every 2-year renewal cycle.

A BCBA provides in-home services to a child. The child's parents, who are very pleased with the services, offer the BCBA a standing invitation to have free meals at their family-owned restaurant. According to the BACB Ethics Code, what is the BCBA's most appropriate course of action?
Answer: B. Politely decline the offer, explaining the ethical guidelines regarding multiple relationships and conflicts of interest.
The BACB Ethics Code strictly prohibits multiple relationships that could impair objectivity, create a conflict of interest, or lead to exploitation. Accepting gifts or services from clients, even if well-intentioned, creates a dual relationship beyond the professional one. The most ethical action is to politely decline and explain the professional boundaries that must be maintained to protect the integrity of the therapeutic relationship.
A BCBA is asked by a local news station to comment on a new fad therapy for autism that lacks empirical support. In their public statement, the BCBA has an ethical responsibility to:
Answer: D. provide statements based on current scientific knowledge and behavior-analytic principles, while avoiding unsubstantiated claims.
Section 5 of the Ethics Code, 'Responsibility in Public Statements,' requires that behavior analysts' statements are based on their conceptually consistent, behavior-analytic knowledge and that they do not make false, deceptive, or exaggerated claims. They must differentiate between what is based on scientific evidence and what is personal opinion. Promoting one's own practice or making sweeping generalizations without evidence would be unethical.
A BCBA is supervising a BCaBA who discloses that they are going through a difficult personal matter that is causing them significant distress. The BCBA has noticed a decline in the BCaBA's performance, including missed deadlines and data errors. What is the BCBA's primary ethical responsibility in this situation?
Answer: A. Address the performance issues with the BCaBA and explore solutions, which may include recommending they seek support for their personal problems and possibly modifying work responsibilities.
The BCBA's ethical obligation is to protect clients by addressing the supervisee's performance deficits. This must be done professionally and supportively. The best course of action involves discussing the performance problems, exploring ways to resolve them (e.g., modified duties, additional support), and recommending the supervisee seek help for personal issues that impact their professional competence, as outlined in the BACB Ethics Code regarding impairment and maintaining competence.
A BCBA is teaching a client to wash their hands. The BCBA provides reinforcement only after the client completes the final step of the task, drying their hands. All preceding steps are prompted. Which behavior-change procedure is the BCBA using?
Answer: B. Backward chaining
Backward chaining is a procedure where the last step in a behavioral chain is taught first, and once mastered, the second-to-last step is taught, and so on, until the entire chain is learned. Reinforcement is delivered upon completion of the terminal step.
