Core Domains
• Philosophical Underpinnings and Concepts of Behavior Analysis
• Measurement, Data Display, and Interpretation
• Experimental Design
• Ethical and Professional Conduct
• Behavior Assessment
• Behavior-Change Procedures
• Selecting and Implementing Interventions
• Personnel Supervision and Management
Introduction
This comprehensive examination is designed to evaluate the knowledge, clinical
reasoning, and applied behavior-analytic skills of candidates preparing for the
Board Certified Behavior Analyst certification examination. The assessment
focuses on the core competency domains established by the BACB Task List,
including philosophical foundations, measurement, experimental design, ethics,
assessment, intervention, and supervision. It integrates foundational behavioral
theory with applied clinical decision-making and problem-solving skills essential
for independent practice. The exam employs multiple-choice and scenario-based
questions to test competency in functional assessment, behavior-change
procedures, ethical practice, and data-based decision-making. Emphasis is placed
,on critical thinking, evidence-based practice, and real-world application to ensure
readiness for professional certification.
SECTION ONE: QUESTIONS 1–550
1. A behavior analyst is conducting a functional analysis of self-injurious
behavior. The analyst hypothesizes that the behavior is maintained by
automatic reinforcement. Which philosophical assumption underlies the
decision to test this hypothesis through direct manipulation rather than
relying on the client's verbal report?
A. Radical behaviorism
B. Methodological behaviorism
C. Structuralism
D. Mentalism
Correct answer
A. Radical behaviorism
RATIONALE: Radical behaviorism includes private events within the
purview of behavioral analysis but insists that they should not be used to
explain other behaviors. The decision to test the hypothesis through direct
environmental manipulation reflects radical behaviorism's commitment to
functional relations between environment and behavior.
2. A behavior analyst observes that a child's tantrums occur more frequently
when the child has not eaten for several hours. The analyst manipulates
pre-session meal consumption and measures tantrum frequency. This
approach BEST reflects which attitude of science?
A. Determinism
B. Empiricism
C. Parsimony
D. Pragmatism
Correct answer
A. Determinism
RATIONALE: Determinism is the assumption that behavior is lawful and
orderly—that it has identifiable causes that can be discovered through
systematic manipulation.
,3. A researcher publishes a study showing that a new intervention reduced
stereotypic behavior. A behavior analyst reads the study and attempts to
replicate the procedures with a different participant population. This
practice BEST illustrates which scientific attitude?
A. Determinism
B. Replication
C. Experimentation
D. Parsimony
Correct answer
B. Replication
RATIONALE: Replication is the repetition of experiments to determine
the reliability and generality of findings.
4. A behavior analyst is explaining the dimensions of applied behavior analysis
to a new supervisee. Which dimension requires that all procedures used in
practice be related to the basic behavioral principles from which they were
derived?
A. Applied
B. Behavioral
C. Conceptually systematic
D. Technological
Correct answer
C. Conceptually systematic
RATIONALE: Conceptually systematic means that all procedures used in
practice should be related to the basic behavioral principles of behavior
analysis from which they were derived.
5. A behavior analyst is working with a client who engages in severe
aggression. Before implementing any intervention, the analyst ensures that
the target behavior is defined in observable and measurable terms. This
practice reflects which dimension of ABA?
A. Applied
B. Behavioral
C. Analytic
, D. Technological
Correct answer
B. Behavioral
RATIONALE: The behavioral dimension requires that the behavior
chosen for change must be the behavior in need of improvement and must
be observable and measurable.
6. A behavior analyst is measuring the number of times a student raises their
hand during a 30-minute class period. Which measurement procedure is
being used?
A. Duration recording
B. Latency recording
C. Event recording
D. Partial interval recording
Correct answer
C. Event recording
RATIONALE: Event recording (frequency/count) involves tallying the
number of times a behavior occurs during an observation period.
7. A behavior analyst is interested in how long it takes a client to begin
working after being given an instruction. Which temporal dimension of
behavior is being measured?
A. Duration
B. Latency
C. Interresponse time
D. Percentage
Correct answer
B. Latency
RATIONALE: Latency is the time between the onset of a stimulus and
the initiation of a response.
8. A researcher is observing a child's play behavior and records whether the
child is engaged in solitary play, parallel play, or associative play every 3
minutes. What measurement procedure is being used?
A. Partial interval recording
