NO. OF QUESTIONS: 85 | Section 1: Measurement (Q1-12) through Section 7: RBT Role,
Supervision, and Safety (Q77-85)
A comprehensive Registered Behavior Technician (RBT) certification practice examination aligned with the BACB
RBT Task List (2nd Edition) and the BACB Ethics Code for RBTs, updated for 2026/2027 requirements. Contains
scenario-based application items, direct recall items, and calculation items covering measurement, assessment, skill
acquisition, behavior reduction, documentation, professional conduct, supervision, and safety, each with a verified
answer and an expert rationale that doubles as study content.
SECTION Section 1: Measurement - Continuous Measurement,
Discontinuous Measurement, Data Graphing, and Interobserver
Agreement (Q1-12)
Q1: A client engaged in 15 instances of hand-raising during a 20-minute observation session. The RBT divides
the count of 15 by the 20 minutes of observation. Which measurement dimension does this calculation represent?
A. Inter-response time
B. Duration
C. Latency
D. Rate [CORRECT]
Correct Answer: D
Rationale: Rate is a count of responses divided by the observation time, expressed as responses per minute or per
hour. A plain count without the time divisor is frequency, while duration measures how long each response lasts.
Latency and inter-response time are temporal measures that never involve dividing a count by observation time (Task
List A-02).
Q2: Which continuous measurement procedure records the total amount of time a client engages in a behavior,
such as the total minutes spent on-task during a work session?
A. Momentary time sampling
B. Inter-response time recording
C. Duration recording [CORRECT]
D. Frequency recording
Correct Answer: C
Rationale: Duration recording captures the elapsed time from the beginning to the end of each behavioral episode.
Frequency only counts occurrences, and momentary time sampling is a discontinuous method that samples behavior at
specific moments. Inter-response time measures the gap between responses rather than time engaged in the behavior
(Task List A-02).

Q3: An RBT says "Get your shoes" and starts a timer. The timer is stopped when the child begins moving toward
the shoe rack 8 seconds later. Which measurement dimension is the RBT recording?
A. Duration
B. Rate
C. Inter-response time
D. Latency [CORRECT]
Correct Answer: D
Rationale: Latency is the elapsed time from the onset of a stimulus, such as an instruction, to the initiation of the
response. Duration would measure how long the shoe-gathering behavior itself lasts, and inter-response time measures
the gap between two consecutive responses. Rate is a count per unit of time and does not apply to a single onset
measure (Task List A-02).
Q4: During a 15-minute observation, an RBT measures the time from the end of one hand-slapping episode to
the start of the next. Which continuous measurement dimension is being recorded?
A. Inter-response time [CORRECT]
B. Rate
C. Latency
D. Duration
Correct Answer: A
Rationale: Inter-response time (IRT) is the amount of time that passes between two successive instances of a
behavior, measured from the end of one response to the beginning of the next. Latency measures stimulus onset to
response initiation, which is different because it begins with a stimulus rather than a completed response. This measure
is valuable when the pacing or spacing of responses matters (Task List A-02).
Q5: A BCBA asks an RBT to report how many tantrum episodes occurred during the session and how long each
episode lasted. Which combination of continuous measurement procedures should the RBT use?
A. Momentary time sampling and partial interval
B. Inter-response time and whole interval
C. Latency and rate
D. Frequency and duration [CORRECT]
Correct Answer: D
Rationale: Frequency records the number of tantrum episodes, and duration records how long each episode lasts, so
these two procedures together capture both requested dimensions. The discontinuous options are sampling estimates
and would not provide exact counts or lengths. Latency and IRT measure onset delay and between-response gaps,
which were not requested (Task List A-02).
Q6: An RBT observes a client in 10-second intervals. The RBT marks the interval if hitting occurs at any point
within that interval, even for 1 second. Which discontinuous measurement procedure is being used?
A. Whole interval recording
B. Momentary time sampling
C. Permanent product recording
D. Partial interval recording [CORRECT]
Correct Answer: D
Rationale: Partial interval recording scores an interval as positive if the behavior occurs at any time during the
interval, no matter how briefly. Whole interval requires the behavior to persist for the entire interval, and momentary
time sampling only checks whether the behavior is occurring at the exact end of the interval. Permanent product
recording measures lasting outcomes rather than live behavior (Task List A-03).
