Free RBT Practice Questions: Measurement Domain

Correct Answer: A

Explanation: Permanent product measurement uses the result of a behavior (the product) to decide if the behavior occurred. The plan defines completion as a wet toothbrush and toothpaste in the sink. Since these are not present, the correct data is that the task was not completed (A). B is incorrect because self‑report is not the defined measurement. C is incorrect because routines do not guarantee the behavior occurred. D is incorrect because the RBT should follow the written measurement procedure and record based on the observed permanent product. The RBT Task List under Measurement includes recording data using permanent products as defined in the program.

Correct Answer: B

Explanation: The plan asks for how many times the behavior happens, which is frequency. The correct response is to count each instance and record the total number (B). A describes duration (how long the behavior lasted), not how many times. C is incorrect because data must be accurate and based on actual observation, not guessing. D is incorrect because it is subjective and does not provide the requested measurement. The RBT Task List under Measurement includes recording frequency data accurately and objectively.

Correct Answer: B

Explanation: You are counting how many times a behavior happens in a set period of time. This is frequency recording, which is on the RBT Task List under Measurement. - B (Frequency) is correct because you are tallying each instance of table hitting during the 30-minute session. - A (Duration) would be used if you were timing how long Maya hits the table, not how many times. - C (Latency) would be used if you were timing how long it takes for Maya to start hitting after a specific instruction or event. - D (IRT) would be used if you were timing the time between one hit and the next hit. Here, you are not timing between responses, just counting them.

Correct Answer: A

Explanation: Partial‑interval recording means you mark the interval if the behavior happens at ANY time during the interval, even for a brief moment. Since Noah flapped for 2 seconds within that 10‑second interval, the interval is scored as occurring (A). B describes whole‑interval recording, which requires the behavior to last the entire interval. C is incorrect because the number of times within the interval does not matter for partial‑interval; any occurrence counts. D is incorrect because partial‑interval does not require a minimum length. The RBT Task List under Measurement includes using discontinuous measurement procedures like partial‑interval correctly.

Correct Answer: A

Explanation: You are measuring how long the behavior lasts from start to finish and adding up the total time. This is duration recording, a core Measurement skill for RBTs. - A (Duration) is correct because you are timing the length of hand-flapping behavior. - B (Latency) would be the time from an instruction or event to the start of hand-flapping, which is not what you are doing. - C (Momentary time sampling) is a discontinuous measurement where you check at specific moments (e.g., at the end of each interval) to see if the behavior is happening, not timing it. - D (Permanent product) is when you measure the result of behavior (like number of worksheets completed), not the behavior as it happens.

Correct Answer: B

Explanation: You are using a discontinuous measurement system where you divide time into intervals and mark the behavior if it happens at any point during the interval. This is partial-interval recording, which is part of the Measurement tasks for RBTs. - B (Partial-interval recording) is correct because you record a “+” if the behavior occurs at any time during the interval. - A (Whole-interval recording) would require the behavior to occur for the entire interval to mark it as happening. - C (Momentary time sampling) would have you check only at the exact end of the interval to see if the behavior is happening at that moment. - D (Frequency recording) would involve counting each instance of off-task behavior, not using intervals with plus/minus marks.

Correct Answer: A

Explanation: The plan asks for total time the behavior occurs, which is duration. Lila cried 5 minutes (2:05–2:10) plus 3 minutes (2:20–2:23), for a total of 8 minutes (A). B is frequency, which is not what was requested. C and D are incorrect because they do not match the actual observed time. The RBT Task List under Measurement includes recording duration by timing how long a behavior lasts and summing the intervals.

Correct Answer: C

Explanation: You are measuring the time from when you give an instruction to when Leo starts the behavior. This is latency, which is part of the Measurement section of the RBT Task List. - C (Latency) is correct because you are timing the delay between the instruction and the start of brushing. - A (Duration) would be used if you were timing how long Leo brushes his teeth from start to finish. - B (Frequency) would be used if you were counting how many times Leo brushes his teeth (for example, number of times per day), not the time to start. - D (Whole-interval recording) is a type of discontinuous measurement where you mark if a behavior happened for the entire interval. That is not what you are doing here.

Correct Answer: C

Explanation: You are measuring the result of Jonah’s behavior (completed math problems) after the behavior has already happened. This is permanent product recording, which is included under Measurement for RBTs. - C (Permanent product recording) is correct because you are counting the completed work as evidence of behavior. - A (Frequency recording) is similar (counting), but is usually used when you directly observe and tally each response as it happens, not just the final product. - B (Duration recording) would involve timing how long Jonah works on the worksheet. - D (Whole-interval recording) is a discontinuous method where you mark if a behavior occurred for the entire interval; that is not what you are doing here.

Correct Answer: B

Explanation: Latency is the time from when an instruction or cue is given until the behavior starts. Here, the instruction is at 3:10:00 and the behavior (starting the puzzle) begins at 3:10:07, so the latency is 7 seconds (B). A is incorrect because duration is how long the behavior continues, not how long it takes to start. C is incorrect because frequency is a count, not a time measure. D is a general note and does not provide the requested latency data. The RBT Task List under Measurement includes recording latency when specified in the plan.
