BCBA MOCK EXAM NEWEST 2026/ 2027 TEST BANK| 2
VERSIONS (VERSION 1 & 2) WITH COMPLETE REAL EXAM
QUESTIONS AND CORRECT VERIFIED ANSWERS/ ALREADY
GRADED A+| BOARD CERTIFIED BEHAVIOR ANALYST MOCK
EXAM REVIEW (MOST RECENT!!)
1. A behavior analyst observes that a learner engages in loud vocalizations
primarily when difficult academic tasks are presented, and the behavior typically
results in the task being removed. Which function of behavior is most strongly
suggested by this pattern?
A. Automatic reinforcement
B. Access to tangible items
C. Escape from demands
D. Attention
Answer: C
2. A BCBA wants to determine whether a newly implemented intervention is
responsible for a reduction in aggression. The BCBA repeatedly measures
aggression during baseline, introduces the intervention, removes it, and then
reintroduces it while continuing measurement. Which single-case design is being
described?
A. Alternating-treatments design
B. ABAB reversal design
C. Multiple-baseline design
,2|Page
D. Changing-criterion design
Answer: B
3. A behavior analyst collects data on the number of times a client independently
initiates communication during each therapy session. Which measurement
dimension is being used?
A. Frequency
B. Latency
C. Duration
D. Interresponse time
Answer: A
4. A client is asked to complete a task, and the BCBA measures the amount of time
between the instruction and the client's initiation of the response. Which
measurement is being used?
A. Duration
B. Latency
C. Frequency
D. Rate
Answer: B

5. A learner engages in hand flapping continuously for approximately 18 minutes
during an observation. The behavior analyst records how long the behavior occurs
from onset to offset. Which measurement dimension is most appropriate?
A. Duration
B. Frequency
C. Latency
D. Percentage
Answer: A
6. A behavior analyst records whether a target behavior occurs at any point during
each 10-second interval, even if it occurs for only a brief moment. Which
discontinuous measurement procedure is being used?
A. Whole-interval recording
B. Partial-interval recording
C. Momentary time sampling
D. Permanent-product recording
Answer: B
7. During a classroom observation, the BCBA records whether the target behavior
is occurring exactly when each 30-second interval ends. Which procedure is being
used?
, 4|Page
A. Partial-interval recording
B. Whole-interval recording
C. Momentary time sampling
D. Frequency recording
Answer: C
8. A behavior analyst wants to determine whether a client's behavior occurs
consistently throughout an entire interval rather than at only one moment within
the interval. Which measurement procedure is most appropriate?
A. Whole-interval recording
B. Momentary time sampling
C. Partial-interval recording
D. Latency recording
Answer: A
9. Two observers independently collect data on the same behavior during the
same session. Their agreement is calculated by dividing the smaller frequency by
the larger frequency and multiplying by 100. Which type of IOA is being
calculated?
A. Total-count IOA
B. Mean-count-per-interval IOA
C. Exact-count-per-interval IOA
