GRADED A+ BOARD CERTIFIED BEHAVIOR ANALYST MOCK EXAM REVIEW (MOST
RECENT!!), with the strongest emphasis placed on Demonstrate mastery of behavior-analytic
concepts and principles, Apply measurement, design, and data-analysis methods in complex
situations and Evaluate and select evidence-based interventions based on functional assessment.
Every item follows the wording style and level of reasoning you meet in the real paper, and each
one is paired with a clear rationale so the correct choice is never a guess. Work through the set at
your own pace, mark the questions that slow you down, then come back to them until the
reasoning feels automatic. Learners who revise this way walk into the exam room recognising the
pattern behind the questions instead of meeting them for the first time. Keep going - steady, honest
practice is what turns a difficult paper into a comfortable pass.
Q1 DEMONSTRATE MASTERY OF BEHAVIOR-ANALYTIC CONCEPTS AND PRINCIPLES
A behavior analyst is designing a measurement system for a behavior that occurs
at high rates but has brief durations. Which combination of measurement methods
would be most appropriate to minimize observer burden while maintaining
accuracy?
A. Whole-interval recording for occurrence and event recording for duration
B. Momentary time sampling for occurrence and duration recording for duration CORRECT
C. Partial-interval recording for occurrence and time sampling for duration
D. Event recording for frequency and permanent product for duration
RATIONALE: Momentary time sampling is efficient for high-rate behaviors and provides a good
estimate of occurrence. Duration recording directly measures the duration of each instance,
which is accurate but may be burdensome; however, the combination of momentary time
sampling (for occurrence) and duration recording (for duration) balances accuracy and effort.
Whole-interval and partial-interval recording are less suited for high-rate brief behaviors.
Permanent product is not applicable for duration.

,Q2 DEMONSTRATE MASTERY OF BEHAVIOR-ANALYTIC CONCEPTS AND PRINCIPLES
Which experimental design would be most appropriate to evaluate the effects of a
token economy on on-task behavior when reversal of the intervention is unethical
due to potential harm?
A. ABAB withdrawal design
B. Multiple baseline across subjects CORRECT
C. Changing criterion design
D. Alternating treatments design
RATIONALE: A multiple baseline design does not require withdrawing the intervention, making it
ethical when reversal is problematic. ABAB requires reversal. Changing criterion is for gradual
behavior change, not for a token economy. Alternating treatments compares treatments, not
necessarily appropriate for evaluating a single intervention's effect.
Q3 DEMONSTRATE MASTERY OF BEHAVIOR-ANALYTIC CONCEPTS AND PRINCIPLES
A functional analysis shows that self-injurious behavior (SIB) is maintained by
access to tangible items. Which intervention is most likely to be effective and
function-based?
A. Noncontingent reinforcement with attention
B. Differential reinforcement of alternative behavior (DRA) with a tangible reinforcer CORRECT
C. Extinction of SIB without providing tangible items
D. Response cost for SIB
RATIONALE: Since SIB is maintained by tangible access, DRA that provides access to tangibles
for an alternative behavior is function-based. Noncontingent attention would not address the
maintaining variable. Extinction alone, while function-based, is not a complete intervention and
may cause an extinction burst. Response cost is punishment, not function-based.

, Q4 DEMONSTRATE MASTERY OF BEHAVIOR-ANALYTIC CONCEPTS AND PRINCIPLES
A behavior analyst is conducting a preference assessment for a client who
engages in challenging behavior when a high-preference item is removed. Which
assessment method is most appropriate to minimize the risk of problem behavior?
A. Free operant observation CORRECT
B. Paired stimulus preference assessment
C. Multiple stimulus without replacement (MSWO)
D. Single stimulus engagement
RATIONALE: Free operant observation allows the client to engage with items freely without
forced removal, reducing the likelihood of problem behavior. Paired stimulus and MSWO require
item removal, which could trigger behavior. Single stimulus engagement also involves removal.
Free operant is the least intrusive and safest.
Q5 DEMONSTRATE MASTERY OF BEHAVIOR-ANALYTIC CONCEPTS AND PRINCIPLES
A behavior analyst is supervising a team implementing a behavior intervention
plan. One team member reports that the client is not making progress. Which
ethical responsibility is most directly relevant to this situation?
A. Ensuring competence of supervisees
B. Using evidence-based interventions
C. Monitoring and modifying treatment plans based on data CORRECT
D. Obtaining informed consent
RATIONALE: The BACB Ethics Code requires behavior analysts to continuously monitor
progress and modify interventions based on data. This is directly relevant when a client is not
progressing. Competence and evidence-based practice are important, but the core issue is the
need to evaluate and adjust the plan. Informed consent is not directly implicated.
