RBT Practice Test Data Collection and Graphing: 2026, 20 Questions

1. During art, Lina places a bead in a cup each time Sam asks for a break during a 10-minute activity. Which measure fits the sheet?

A Correct. Task A.1 includes recording each occurrence when the plan calls for a response count.
B Timing the whole activity would not count each request made during the activity.
C Checking only at timer beeps is a sampling method, not a count of every request.
D Reviewing completed products fits durable work output, not live requests.

2. During reading, Omar leaves his chair and returns after different amounts of time. The sheet asks how long each episode lasts. Which measure fits?

A Counting each exit would give frequency, not the length of each episode.
B Correct. Task A.1 includes duration when the sheet asks how long behavior lasts.
C Interval scores sample occurrence and do not measure each episode from start to end.
D Inspecting work afterward would not time out-of-chair episodes while they occur.

3. Maya gives the instruction "touch the card." Jonah touches the card five seconds later. Which measure fits?

A Counting would report the number of touches, not the time after the instruction.
B Duration measures how long a response continues after it begins.
C Correct. Task A.1 includes latency, measured from the instruction to the start of the response.
D End-of-interval scoring samples a moment instead of the start after the instruction.

4. At centers, Jamal hums once near the middle of a 30-second block. The sheet says yes when the response happens at least once. How should the block be marked?

A Requiring the response throughout the block would apply a different interval rule.
B Checking only at the beep would apply a momentary sampling rule.
C Counting every hum changes the sample into a frequency count.
D Correct. Task A.2 includes scoring the interval yes when the written rule says one occurrence is enough.

5. During a 20-second block, Nora keeps her hands folded for 18 seconds and then reaches away. The sheet says yes only when the response lasts the whole block. How should it be scored?

A Correct. Task A.2 includes following the full-block rule, and 18 seconds is not the whole block.
B Scoring yes for most of the time changes the stated rule.
C Counting separate times would be a response count, not the interval score requested.
D Checking only at the beep uses a different sampling method.

6. At the end of each minute, Priya checks whether Leo is reading at that exact signal. Which rule matches the sheet?

A Scoring any occurrence would include behavior that happened earlier in the minute.
B Correct. Task A.2 includes sampling whether behavior occurs at the specified moment.
C Requiring the full block would score sustained behavior across the interval.
D Counting page turns would measure a separate response count.

7. After handwriting practice, Mei counts legible copied words from the finished page. Which recording method fits?

A Live interval sampling would require observing behavior during the session.
B Cue-to-response timing measures delay after an instruction.
C Correct. Task A.3 includes measuring a durable result after the response has occurred.
D Full-session duration measures elapsed time, not the finished work product.

8. A plan allows checking completed sorting cards after the learner leaves the table. What must be true for that method to work?

A Hearing each response is not required when the lasting product is the measure.
B If the behavior has no lasting result, this method would not fit.
C Timer samples are used for interval procedures, not product review.
D Correct. Task A.3 depends on a durable result that can be checked after behavior occurs.

9. Nia is entering session totals and sees the paper sheet lists 12 responses while yesterday's graph point shows 21. What should she do before adding today's point?

A Correct. Task A.4 includes accurate transfer from source records before graph updates.
B Smoothing a line would change the display rather than resolve the mismatch.
C Estimating a value would create an unsupported record.
D Skipping a session would not correct the existing graph issue.

10. A graph key says blue circles show prompted responses and black squares show independent responses. A new point uses the wrong symbol. What is the best correction?

A A correct value with the wrong symbol can still misrepresent the data path.
B Correct. Task A.4 includes updating graphs so the display matches the recorded data.
C Moving the point changes the session location instead of correcting the symbol.
D Averaging the paths would combine different response types.

11. Which session note would let another observer identify the same response?

A "Upset" is an interpretation unless observable responses are described.
B "Attention-seeking" states a possible function rather than the observed response.
C Correct. Task A.5 includes observable and measurable descriptions, and this note states an action and count.
D "Avoided hard work" infers purpose without naming the measurable response.

12. The note needs an objective setting detail from recess. Which wording is most measurable?

A "Felt chaotic" is subjective and does not give a measurable setting event.
B "Too many" is a judgment unless the note states the count or event.
C "Stressful" interprets the situation rather than describing it.
D Correct. Task A.5 includes observable environmental descriptions, and the bell time is objective.

13. During a 15-minute timing, Elena records 9 independent labels. What rate per hour should the summary show?

A Correct. Task A.6 includes rate; 15 minutes is one quarter of an hour, so 9 multiplied by 4 equals 36 per hour.
B Twenty-four per hour would not follow from four equal 15-minute blocks.
C Fifteen per hour uses the minutes as if they were responses.
D Nine per hour reports the raw count without scaling to an hour.

14. Three tantrum episodes last 2, 4, and 6 minutes. What mean duration should the RBT report?

A Three minutes is below the average of the three episode lengths.
B Correct. Task A.6 includes mean duration; 2 plus 4 plus 6 equals 12, and 12 divided by 3 equals 4.
C Six minutes is the longest episode, not the mean.
D Twelve minutes is the total duration before dividing by the number of episodes.

15. A probe has 18 independent steps out of 24 total steps. What percentage is independent?

A Sixty-five percent is lower than 18 divided by 24.
B Seventy percent would equal 16.8 out of 24, not 18.
C Correct. Task A.6 includes percentage summaries; 18 divided by 24 equals 0.75.
D Eighty percent would equal 19.2 out of 24, not 18.

16. Across four sessions, correct responses are 14, 12, 9, and 7. Which description stays closest to the display?

A A stable level would stay near the same value across sessions.
B A variable bounce would move up and down without a clear direction.
C A higher level each day would require the points to increase.
D Correct. Task A.7 includes identifying the visible pattern, and these points decrease across sessions.

17. A graph has points at 3, 12, 4, 11, and 5 with no steady direction. Which description is most objective?

A Correct. Task A.7 includes describing visible variability when points move up and down.
B A steady upward pattern would show a consistent increase.
C A flat level pattern would stay close to the same value.
D A graph alone does not prove that treatment caused the change.

18. After a phase-change line, data points move from around 2 per session to around 8 per session. Which statement is closest?

A The later points are higher, not lower, than the earlier points.
B Correct. Task A.7 includes identifying changes in level shown on a graph.
C A visible level shift appears when the points move from around 2 to around 8.
D The graph shows a pattern, but a single statement should not overclaim cause.

19. Two staff use different start and stop rules for the same out-of-seat episodes. What is the main problem?

A Adding reinforcers does not resolve inconsistent measurement rules.
B Graph colors do not address whether observers score the same response the same way.
C Correct. Task A.8 includes recognizing that unreliable collection can make scores inconsistent.
D Session length is not the problem described by different start and stop rules.

20. A teaching step is skipped, but the trial is still scored as independent. What concern should the team recognize?

A Faster entry does not fix a mismatch between implementation and scoring.
B More sampling time does not correct a skipped teaching step.
C Generalization is not shown by an inaccurate independent score.
D Correct. Task A.8 includes risks from poor procedural fidelity because the data may no longer represent what was actually implemented.
