1. Question 1 of 25Easy

   A behavior analyst asks an RBT to complete a scatterplot data sheet for a client's motor stereotypy across a 6-hour school day. The sheet is divided into 30-minute intervals. What information is the RBT primarily recording in each interval block?

   1. AA. The level or occurrence of the target behavior during that specific time period
   2. BB. The exact duration in seconds of every stereotypy episode
   3. CC. The consequence that immediately followed the client's behavior
   4. DD. The specific antecedent that triggered each instance of stereotypy
   Show answer to question 1

   Answer: A. The level or occurrence of the target behavior during that specific time period

   Scatterplots record the extent to which a target behavior occurs across standardized intervals or time blocks of the day. Antecedents and consequences are captured during descriptive ABC data collection, not on standard scatterplots. Exact duration in seconds would be captured using continuous duration recording rather than interval-based scatterplot coding.

2. Question 2 of 25Easy

   A supervisor asks an RBT to assist with a developmental skill assessment for a new learner. Which task is appropriate for the RBT to complete?

   1. AA. Conducting structured skill probes following the supervisor's explicit instructions
   2. BB. Designing new probe materials based on personal clinical judgment
   3. CC. Writing the final assessment report summarizing the learner's developmental delays
   4. DD. Selecting which developmental assessment tool is most appropriate for the learner
   Show answer to question 2

   Answer: A. Conducting structured skill probes following the supervisor's explicit instructions

   RBTs may assist with skill assessments by running specific probes and recording data under the direct supervision of a BCBA. Selecting assessment batteries, writing formal assessment reports, and designing clinical tools are responsibilities reserved for the supervising behavior analyst.

3. Question 3 of 25Easy

   During a paired stimulus preference assessment, the RBT presents two toys and instructs the learner to make a selection. The learner looks away and makes no approach to either toy within the designated 5-second interval. What is the most appropriate action for the RBT to take?

   1. AA. Replace one of the toys with an edible item and restart the 5-second timer.
   2. BB. Guide the learner's hand to touch one of the toys using physical prompting.
   3. CC. Remove both toys, record that no selection was made, and present the next pair.
   4. DD. Leave the toys on the table until the learner eventually approaches one.
   Show answer to question 3

   Answer: C. Remove both toys, record that no selection was made, and present the next pair.

   When a learner does not select either item within the designated response interval, the RBT removes both items, records non-selection for that trial, and moves on to the next pair. Using physical prompting is inappropriate because preference assessments measure independent choice, not prompted compliance.

4. Question 4 of 25Medium

   A supervisor explains that while descriptive data reveal correlations, an analog functional analysis is needed to confirm the function of a learner's aggression. What is the primary advantage of a functional analysis over descriptive assessment?

   1. AA. It verifies causal relationships by systematically manipulating environmental variables
   2. BB. It relies exclusively on caregiver interviews rather than direct observations
   3. CC. It captures behavior purely in the natural environment without introducing changes
   4. DD. It requires less staff training and allows data collection across entire therapy shifts
   Show answer to question 4

   Answer: A. It verifies causal relationships by systematically manipulating environmental variables

   A functional analysis isolates and systematically manipulates specific antecedents and consequences to demonstrate an actual functional (causal) relation. Descriptive assessments only observe what happens naturally, which demonstrates correlation rather than causation.

5. Question 5 of 25Hard

   A BCBA gives an RBT a written list of items, a randomized pair order, and a data sheet for a paired stimulus preference assessment. Which task is within the RBT's role?

   1. AA. Presenting the pairs as listed and recording which item is chosen on each trial
   2. BB. Deciding that the assessment should be replaced with a different procedure
   3. CC. Determining the overall preference hierarchy from the completed data sheet
   4. DD. Changing the item list after noticing which items are chosen less often
   Show answer to question 5

   Answer: A. Presenting the pairs as listed and recording which item is chosen on each trial

   The RBT implements the prepared assessment by presenting the specified pairs and recording choices accurately. Revising the item list, interpreting the preference hierarchy, and changing the assessment procedure are supervisor responsibilities.

6. Question 6 of 25Easy

   An RBT places five bite-sized snacks in a straight line in front of a client. The client chooses a cracker. After the client consumes it, the RBT sets out another cracker along with the other four snacks, altering their physical order before prompting the client to choose again. Which preference assessment is being conducted?

   1. AA. Single stimulus preference assessment
   2. BB. Paired stimulus preference assessment
   3. CC. Multiple stimulus without replacement
   4. DD. Multiple stimulus with replacement
   Show answer to question 6

   Answer: D. Multiple stimulus with replacement

   Placing the chosen item (or an identical edible replacement) back into the array while rotating item positions is the defining feature of Multiple Stimulus with Replacement (MSW). In Multiple Stimulus without Replacement (MSWO), the chosen item is withheld on subsequent trials, causing the array to shrink. Paired stimulus involves presenting two items at a time, while single stimulus presents items individually.

7. Question 7 of 25Medium

   An RBT is conducting a social skills probe assessing whether a learner will share a tablet when a peer asks, 'Can I play?' The protocol specifies that this is an unprompted baseline probe. When the peer asks, the learner hesitates and looks directly at the RBT. How should the RBT respond?

   1. AA. Withhold prompts, observe for the designated time interval, and record the result
   2. BB. Offer the learner an edible reinforcer contingent on handing the tablet to the peer
   3. CC. Instruct the peer to repeat the question louder so the learner clearly understands
   4. DD. Deliver a gentle physical prompt guiding the learner's hands to hand over the tablet
   Show answer to question 7

   Answer: A. Withhold prompts, observe for the designated time interval, and record the result

   During an unprompted baseline probe, the technician must observe and measure independent performance without coaching, prompting, or contriving artificial reinforcement. Delivering a physical prompt turns the assessment trial into a prompted teaching trial, which invalidates the baseline data.

8. Question 8 of 25Medium

   A supervisor asks an RBT to probe a learner's adaptive skills by presenting a sequence of everyday tasks and recording performance. Before starting, what should the RBT confirm?

   1. AA. Whether the learner's parents will be told the assessment results today.
   2. BB. Which teaching procedure to begin if the learner fails an assessment item.
   3. CC. The learner's expected total score on the adaptive skills assessment.
   4. DD. The specific response definitions and recording method the supervisor wants used.
   Show answer to question 8

   Answer: D. The specific response definitions and recording method the supervisor wants used.

   Clear response definitions and recording procedures are needed so the RBT collects consistent, objective data during the probe. Knowing the expected score is unnecessary, and deciding on a teaching procedure or discussing results with parents would require the supervisor's clinical judgment.

9. Question 9 of 25Easy

   A supervisor asks an RBT to run a preference assessment in which all items are available to the learner for the whole session and no item is ever taken away. This describes which procedure?

   1. AA. Free operant
   2. BB. Multiple stimulus without replacement
   3. CC. Multiple stimulus with replacement
   4. DD. Paired stimulus
   Show answer to question 9

   Answer: A. Free operant

   A free operant assessment gives the learner continuous access to all items at once, and the RBT records how long the learner engages with each item; there are no trials and no items are removed. The three trial-based procedures all involve presenting a limited array and recording selections rather than duration of engagement.

10. Question 10 of 25Easy

    An RBT is preparing to assist a BCBA with conducting a functional analysis of severe physical aggression. According to standard safety guidelines, what should the RBT do prior to beginning the session?

    1. AA. Withhold preferred reinforcers for several hours to ensure compliance.
    2. BB. Remove hard or sharp objects from the session area to minimize injury risk.
    3. CC. Modify the condition order based on the learner's current mood.
    4. DD. Allow the learner to review the assessment materials to reduce anxiety.
    Show answer to question 10

    Answer: B. Remove hard or sharp objects from the session area to minimize injury risk.

    Before beginning an assessment that deliberately evokes aggressive behavior, clearing the physical environment of hazardous items reduces the risk of injury to both the client and staff. Modifying the condition order is a clinical decision reserved for the supervisor, not a pre-session safety task for an RBT.

11. Question 11 of 25Medium

    While conducting an ABC observation, an RBT learns from the parent that the client slept only four hours the previous night. During the session, the RBT presents a puzzle, and the client engages in crying. How should the RBT document this information when completing the ABC data sheet?

    1. AA. Disregard the presentation of the puzzle and list only fatigue as the primary trigger.
    2. BB. Record the four hours of sleep as the immediate antecedent for crying.
    3. CC. Record crying as the antecedent and lack of sleep as the maintaining consequence.
    4. DD. Record the puzzle presentation as the antecedent and note the lack of sleep as a setting event.
    Show answer to question 11

    Answer: D. Record the puzzle presentation as the antecedent and note the lack of sleep as a setting event.

    Antecedents are immediate environmental changes that occur directly prior to the behavior, which in this scenario is the presentation of the puzzle. Lack of sleep is a setting event or motivating operation that may increase the value of escape, but because it did not occur immediately prior to the behavior, it belongs in notes or setting event tracking rather than as the immediate antecedent.

12. Question 12 of 25Easy

    An RBT is conducting a descriptive ABC assessment during a learner's independent play session. When should the RBT record the ABC data entries?

    1. AA. After conferring with the supervising BCBA about the suspected function of the behavior.
    2. BB. At scheduled five-minute intervals regardless of whether the behavior occurred.
    3. CC. Immediately following the occurrence of each instance of the targeted behavior.
    4. DD. At the conclusion of the therapy session to avoid interrupting the client's play routine.
    Show answer to question 12

    Answer: C. Immediately following the occurrence of each instance of the targeted behavior.

    ABC data must be documented immediately after the target behavior occurs to ensure that antecedent and consequence events are recorded accurately. Delaying data collection until the end of the session introduces significant recall error and reduces reliability. Fixed-interval recording does not align with event-based ABC observations, and RBTs do not wait to determine a behavior's function before recording objective data.

13. Question 13 of 25Medium

    An RBT is conducting a Multiple Stimulus with Replacement (MSW) preference assessment using six edible items. On the first trial, the learner selects and consumes a pretzel. Which step should the RBT take before presenting the second trial?

    1. AA. End the assessment because the learner has demonstrated a clear preference on trial one.
    2. BB. Replace the consumed pretzel with an identical one and rotate the positions of the items.
    3. CC. Remove the pretzel category completely and present the remaining five edibles.
    4. DD. Offer the learner a choice between the pretzel and one newly introduced edible item.
    Show answer to question 13

    Answer: B. Replace the consumed pretzel with an identical one and rotate the positions of the items.

    In an MSW assessment, selected items are replaced (or a duplicate is added back if consumed) so the learner encounters the entire array on every trial. Removing the item and presenting only the remaining edibles describes an MSWO procedure rather than an MSW procedure.

14. Question 14 of 25Medium

    A learner's communication plan lists the target "requests water." During a probe the learner says "wawa." This does not match the defined target form. What is the best way for the RBT to record the response?

    1. AA. Write "requested water" because the meaning was clear
    2. BB. Write down exactly what the learner said on the data sheet
    3. CC. Write "noncompliant" because the target form was not used
    4. DD. Write "incorrect" with no other detail about the response
    Show answer to question 14

    Answer: B. Write down exactly what the learner said on the data sheet

    Recording the exact vocal response gives the supervisor the accurate information needed to judge whether the target was met. Writing "requested water" overstates the response, and labeling it noncompliant describes the learner rather than the response.

15. Question 15 of 25Medium

    The supervisor's protocol defines toy engagement as 'actively touching, manipulating, or looking directly at the item.' While tracking duration with a puzzle, the client sets a piece down, turns around, and gazes out the window for two minutes before returning to the puzzle. What should the RBT do?

    1. AA. Physically prompt the client to pick up the puzzle piece while keeping the timer running
    2. BB. Keep the timer running because the client is still sitting at the puzzle station
    3. CC. Terminate the assessment session immediately due to an off-task interval
    4. DD. Pause the duration timer when the client turns away and resume it when puzzle interaction begins again
    Show answer to question 15

    Answer: D. Pause the duration timer when the client turns away and resume it when puzzle interaction begins again

    The RBT must pause the duration timer as soon as the client's behavior no longer meets the operational definition of engagement and resume timing only when engagement begins again. Leaving the timer running while the client gazes out the window artificially inflates engagement time and skews the assessment results.

16. Question 16 of 25Medium

    An RBT is instructed to prepare a room for an alone condition during a functional analysis testing for automatic reinforcement. Which setup should the RBT prepare?

    1. AA. A room stocked with varied sensory toys while the technician sits nearby to prompt independent play
    2. BB. A standard classroom desk with academic folders and a timer counting down until the technician returns
    3. CC. A therapy area containing continuous preferred snacks while the technician observes quietly from the corner
    4. DD. An environment stripped of leisure materials and demands, with safety monitoring and no social interaction
    Show answer to question 16

    Answer: D. An environment stripped of leisure materials and demands, with safety monitoring and no social interaction

    The alone condition evaluates whether behavior persists in the absence of social consequences, demands, and preferred materials; therefore, the room must be cleared of tasks and leisure items while ensuring the learner is safe and monitored. Supplying sensory toys or preferred snacks introduces extraneous stimulation that would confound testing for automatic reinforcement.

17. Question 17 of 25Medium

    After a paired-stimulus preference assessment, the learner selects a toy car most often. What is the most accurate conclusion?

    1. AA. The car should be used in every teaching session from now on
    2. BB. The car is the likely cause of the learner's problem behavior
    3. CC. The car is highly preferred and may work as a reinforcer
    4. DD. The car has been proven to increase correct responding
    Show answer to question 17

    Answer: C. The car is highly preferred and may work as a reinforcer

    A paired-stimulus preference assessment produces a ranking of preferred stimuli, so the most-selected car is a strong candidate for reinforcement. It does not prove the car will increase responding; that requires a reinforcer assessment. The results also do not identify the cause of problem behavior or require exclusive use of one item.

18. Question 18 of 25Medium

    A supervisor instructs an RBT to conduct a free operant preference assessment instead of a structured paired-stimulus assessment for a client who engages in aggression when toys are removed. What is the primary clinical rationale for this decision?

    1. AA. It requires the client to select between two items simultaneously.
    2. BB. It produces a more distinct ranking of low-preference items.
    3. CC. It prevents challenging behavior evoked by the removal of items.
    4. DD. It requires less preparation of materials before the session begins.
    Show answer to question 18

    Answer: C. It prevents challenging behavior evoked by the removal of items.

    A primary benefit of a free operant preference assessment is that the technician does not withdraw or restrict access to items once chosen, reducing the risk of problem behavior triggered by item removal. Structured assessments, such as paired stimulus, require the technician to repeatedly take items away after each trial to present the next pair.

19. Question 19 of 25Hard

    A free operant observation is typically chosen rather than a paired stimulus assessment when:

    1. AA. the plan calls for comparing items two at a time.
    2. BB. the learner may show problem behavior when items are removed.
    3. CC. the supervisor needs a ranked order of only the top two items.
    4. DD. the learner gives items back willingly after each selection.
    Show answer to question 19

    Answer: B. the learner may show problem behavior when items are removed.

    Because nothing is taken away during a free operant observation, it is well suited to learners who tolerate item removal poorly or who may engage in problem behavior when preferred items are withdrawn. A learner who readily gives items back does not need this accommodation, and comparing items two at a time is the definition of a paired stimulus assessment.

20. Question 20 of 25Medium

    An RBT is running baseline trials to assess a learner's listener responding skills with picture cards. How should the RBT deliver the instructions across trials to prevent unintentional cueing?

    1. AA. Look directly at the correct picture card while delivering the vocal instruction.
    2. BB. Repeat the target word several times with increasing vocal emphasis.
    3. CC. Maintain neutral eye contact and present the materials in the assigned layout.
    4. DD. Place the target picture card closer to the learner on every assessment trial.
    Show answer to question 20

    Answer: C. Maintain neutral eye contact and present the materials in the assigned layout.

    Maintaining neutral eye contact and strictly adhering to the predetermined card layout ensures that the client responds to the vocal instruction alone, rather than subtle non-verbal cues. Looking at the correct card or moving it closer inadvertently prompts the response and invalidates baseline data.

21. Question 21 of 25Hard

    An RBT records baseline data on a learner's rate of independently following one-step directions. The RBT then delivers 30 seconds of access to a favorite puzzle contingent on following each direction. After five sessions, the rate of following directions doubles compared to baseline. What has been demonstrated?

    1. AA. The puzzle has eliminated all competing establishing operations for off-task behavior.
    2. BB. The learner has developed a generalized conditioned reinforcer across all settings.
    3. CC. The puzzle is a demonstrated reinforcer for the learner's direction-following behavior.
    4. DD. The direction-following behavior has successfully generalized across multiple stimulus classes.
    Show answer to question 21

    Answer: C. The puzzle is a demonstrated reinforcer for the learner's direction-following behavior.

    Because the delivery of the puzzle contingent upon following directions resulted in a measurable increase in the future rate of following directions compared to baseline, the puzzle has been experimentally demonstrated to function as a reinforcer. A single behavior-consequence demonstration does not prove generalization across settings or that the stimulus is a generalized conditioned reinforcer.

22. Question 22 of 25Hard

    While reviewing an ABC data sheet with an RBT, a BCBA notes that the RBT frequently lists 'noisy hallway' in the antecedent column for instances of aggression. However, the hallway noise was continuous for two hours, while the aggression occurred only when the RBT placed a math folder on the desk. How should the RBT correct this documentation?

    1. AA. Record both the continuous noise and the presentation of the math folder as consequences.
    2. BB. Record the continuous noise as a setting event and the presentation of the math folder as the antecedent.
    3. CC. Remove the mention of noise entirely and record the client's internal frustration as the antecedent.
    4. DD. Record the presentation of the math folder as a setting event and the continuous noise as the antecedent.
    Show answer to question 22

    Answer: B. Record the continuous noise as a setting event and the presentation of the math folder as the antecedent.

    The continuous hallway noise is an environmental context variable present across time that may heighten reactivity, making it a setting event, whereas the math folder placement is the immediate stimulus change directly triggering the aggression. Behavior analysts do not record unobservable internal emotional states such as frustration as antecedents on descriptive logs.

23. Question 23 of 25Hard

    An RBT conducts a single stimulus preference assessment across eight different items and notes that the learner approached 100% of the items presented. What known limitation of recording single stimulus approach responses does this outcome illustrate?

    1. AA. It artificially suppresses response rates due to the absence of concurrent competition.
    2. BB. It can produce false positives by failing to differentiate relative preference among items.
    3. CC. It requires the client to demonstrate complex discrimination skills between stimuli.
    4. DD. It forces the client to display an unrepresentative position bias across trials.
    Show answer to question 23

    Answer: B. It can produce false positives by failing to differentiate relative preference among items.

    A primary limitation of the single stimulus method is that individuals often approach nearly every item presented, creating false positives that mask the true hierarchy of relative preference. It does not suppress response rates or induce position biases; rather, it often inflates approach rates because no alternative choice is available to compete with the presented item.

24. Question 24 of 25Hard

    Which statement best distinguishes a functional analysis from an ABC recording?

    1. AA. A functional analysis depends on caregiver recall, whereas ABC recording is a direct observation method.
    2. BB. A functional analysis is an indirect method, whereas ABC recording is an experimental method.
    3. CC. A functional analysis uses scatterplot summaries, whereas ABC recording uses rating scales.
    4. DD. A functional analysis manipulates antecedents and consequences, whereas ABC recording does not.
    Show answer to question 24

    Answer: D. A functional analysis manipulates antecedents and consequences, whereas ABC recording does not.

    A functional analysis is a direct experimental assessment in which antecedents and consequences are systematically arranged to test hypotheses. ABC recording is direct but descriptive because it does not manipulate variables. Saying functional analysis relies on recall or is indirect misclassifies it.

25. Question 25 of 25Hard

    Before a curriculum-based assessment session, an RBT notices that the listed materials look far below the client's current skill level. What is the best action for the RBT to take?

    1. AA. Skip the early items and begin where the client is likely to succeed
    2. BB. Run the assessment as written, then report the concern to the supervisor
    3. CC. Tell the client the items are too easy and ask which ones they want to try
    4. DD. Replace the items with harder ones from the next level of the curriculum
    Show answer to question 25

    Answer: B. Run the assessment as written, then report the concern to the supervisor

    The RBT runs the assessment as the supervisor wrote it and reports observations, leaving any revision of the materials to the supervisor. Skipping ahead or swapping in harder items is tempting when the items look too easy, but it changes the assessment and may leave the supervisor with incomplete or unusable data. Asking the client to pick items also departs from the written procedure.
