Reinforcer selection does not define response instances.
Future graph trends cannot resolve current scoring rules.
Answer: A. A clear onset, offset, and rule for separating response instances
Response boundaries and episode-separation rules tell observers when one occurrence ends and another begins.
Exam takeaway: Counting requires a repeatable rule for when responses start, stop, and separate.
Question 5 · Task A.6 · Data Collection & Graphing
A learner responds correctly on 8 of 10 trials. What percentage is correct?
This uses the error percentage.
This understates the ratio.
Correct; part ÷ total × 100 = 80%.
This reverses the ratio.
Answer: C. 80%
Percentage equals the part divided by the total opportunities, multiplied by 100; each ratio equals 80%.
Exam takeaway: Percentage = part ÷ whole × 100.
Question 6 · Task A.7 · Data Collection & Graphing
Successive graphed values are 2, 3, 5, 6, and 8. Which trend should the RBT report?
An increasing trend is a general upward direction across successive observations.
A decreasing trend is a general downward direction across successive observations.
No consistent trend describes a variable or roughly level series without a sustained direction.
A pattern in one graphed series alone does not establish an experimental functional relation.
Answer: A. Increasing trend
The values generally rise across successive observations, indicating an increasing trend.
Exam takeaway: Trend is the overall direction, not whether every adjacent point changes identically.
Behavior Assessment practice questions
Question 7 · Task B.1 · Behavior Assessment
The RBT presents stickers and music together, records one selection, and later repeats the process with every planned pair. Which assessment is this?
Paired stimulus presents two items at a time and records the selection from each pair.
MSWO presents an array, removes each selected item, and rearranges the remaining items across trials.
Free operant makes several activities or items available and measures engagement without forced trials.
A functional analysis tests behavior-environment relations; it is not a preference assessment.
Answer: A. Paired-stimulus preference assessment
A paired-stimulus assessment presents two stimuli on each trial and compares selections across planned pairs.
Exam takeaway: Two choices per trial signals a paired-stimulus assessment.
Question 8 · Task B.1 · Behavior Assessment
An item is highly preferred, but responding does not increase when the item follows the target behavior. What does this demonstrate?
High selection can identify a candidate, but selection alone does not demonstrate reinforcement.
Reported liking does not establish an effect on future behavior.
Preference and behavioral function are different assessment questions.
Correct; the defining evidence is the effect of a contingent consequence on future responding.
Answer: D. Contingent delivery must increase or maintain the future target response under the relevant conditions
Reinforcement is demonstrated by a future increase or maintenance of behavior following contingent stimulus delivery.
Exam takeaway: Call a stimulus a reinforcer only when its contingent use has the defining behavioral effect.
Question 9 · Task B.2 · Behavior Assessment
A supervisor directs an RBT to prepare standardized materials during a skill assessment. What is the RBT’s responsibility?
Correct; accurate implementation and reporting fit the RBT role.
Assessment design and target selection require supervisor direction.
Independent diagnostic interpretation is outside the RBT role.
Teaching during a probe can invalidate a measure intended to sample current skill.
Answer: A. Perform the trained component exactly as directed and report observations objectively
An RBT may assist with trained assessment components while following the protocol and reporting data to the supervisor.
Exam takeaway: Assist with assigned components; do not independently design, diagnose, or alter the assessment.
Question 10 · Task B.3 · Behavior Assessment
An RBT participates by collecting ABC observations during regular class, with no condition deliberately changed. Which assessment type is this?
Indirect assessment gathers reports through interviews, questionnaires, checklists, or record review.
Descriptive assessment directly observes behavior and naturally occurring events without experimental manipulation.
Functional analysis systematically manipulates relevant conditions to test their effects on behavior under qualified direction.
Preference assessment identifies relative selection or engagement, not the function of problem behavior.
Answer: B. Descriptive assessment
Descriptive assessment observes behavior and environmental events as they naturally occur without systematic experimental manipulation.
Exam takeaway: Direct naturalistic observation can suggest patterns, but it does not by itself prove a function.
Behavior Acquisition practice questions
Question 11 · Task C.1 · Behavior Acquisition
Maya completes raising a hand before speaking. The RBT immediately provides two minutes of drawing, and the skill occurs more often later. Which process is demonstrated?
Correct: a valued event was added and the response increased.
Negative reinforcement removes or postpones an aversive event.
Positive punishment adds a consequence that decreases behavior.
Extinction withholds the reinforcer that previously maintained behavior.
Answer: A. Positive reinforcement
A stimulus was added immediately after the response, and future responding increased. That pattern defines positive reinforcement.
Exam takeaway: Classify reinforcement by its effect on future behavior, then note whether a stimulus was added or removed.
Question 12 · Task C.2 · Behavior Acquisition
After Maya completes packing a backpack, the RBT says “Nice work” and also provides two minutes of drawing. What is the likely purpose of pairing praise with the reinforcer?
The procedure is intended to strengthen, not punish.
An establishing operation changes reinforcer value; praise is the paired stimulus here.
Correct: praise can become reinforcing through pairing.
Data are still needed to evaluate the procedure.
Answer: C. To help praise acquire reinforcing value
Pairing praise with an effective reinforcer can condition praise so it later supports behavior more independently.
Exam takeaway: Social stimuli can become conditioned reinforcers when paired systematically with effective outcomes.
Question 13 · Task C.4 · Behavior Acquisition
While Maya is motivated for two minutes of drawing in classroom, the RBT creates an opportunity to use raising a hand before speaking. Which teaching feature is most naturalistic?
Correct: motivation and outcome are functionally connected.
Table-only teaching is more characteristic of structured instruction.
Long delays weaken the natural contingency.
Learner initiation is often a key teaching opportunity.
Answer: A. The reinforcer is related to the learner’s current activity and motivation
Naturalistic teaching embeds instruction in ongoing activities and uses relevant motivation and natural outcomes.
Exam takeaway: Naturalistic teaching follows motivation and uses outcomes connected to the activity.
Question 14 · Task C.5 · Behavior Acquisition
The plan uses total-task teaching for packing a backpack. How should the RBT proceed?
This resembles a single-link chaining approach, not total task.
Changing order disrupts the task analysis.
Correct: every link is practiced in sequence.
Prompted performance is still important data.
Answer: C. Give ${c.learner} an opportunity on every step and prompt each step as prescribed
Total-task presentation provides a response opportunity on each step during each teaching occasion, with prompts and reinforcement as written.
Exam takeaway: In total-task teaching, the learner practices the full sequence with step-specific support.
Question 15 · Task C.7 · Behavior Acquisition
The RBT gently guides Maya's hand through part of raising a hand before speaking. What type of prompt is this?
Correct: the prompt acts on the response itself.
Stimulus prompts alter or add features to the antecedent stimulus.
A motivating operation changes the value of a consequence.
Guidance occurs before or during the response, not as its consequence.
Answer: A. A response prompt
Physical guidance directly assists the learner’s response, making it a response prompt.
Exam takeaway: Response prompts act on what the learner does; stimulus prompts alter what the learner sees or hears.
Question 16 · Task C.8 · Behavior Acquisition
To help Maya use raising a hand before speaking in classroom, the teaching team includes materials also found there. Which strategy is this?
No maintaining reinforcer is withheld.
No earned reinforcer is removed.
Correct: shared cues bridge training and use settings.
The strategy broadens transfer rather than fixing a position.
Answer: C. Programming common stimuli
Common stimuli shared by training and natural settings can cue the learned response in both places.
Exam takeaway: Bring relevant natural cues into teaching and teaching cues into natural environments when appropriate.
Question 17 · Task C.10 · Behavior Acquisition
Maya cannot yet perform raising a hand before speaking. The plan reinforces closer and closer versions of the skill. Which procedure is this?
Correct: response form changes gradually toward the target.
Chaining links distinct steps into a sequence.
Extinction withholds reinforcement for a previously reinforced response.
NCR delivers reinforcement independently of responding.
Answer: A. Shaping
Shaping reinforces successive approximations toward a target response.
Exam takeaway: Shaping changes one response dimension through successive approximations.
Behavior Reduction practice questions
Question 18 · Task D.1 · Behavior Reduction
In classroom, an adult consistently talks to Maya immediately after calling out. Data show the behavior increases when this occurs. Which function best matches this pattern?
Correct: another person delivers attention after the response.
Escape requires behavior to delay, reduce, or remove a demand.
Tangible access requires behavior to produce an item or activity.
Automatic reinforcement does not require another person to deliver the consequence.
Answer: A. Attention
Social interaction follows the behavior and is associated with an increase, which is consistent with an attention function.
Exam takeaway: Attention-maintained behavior produces a socially delivered response from another person.
Question 19 · Task D.2 · Behavior Reduction
The antecedent plan for Maya's calling out calls for delivering brief teacher attention on a time-based schedule, regardless of behavior. Which procedure is this?
Correct: delivery is time based and response independent.
DRL reinforces responding at or below a rate criterion.
Response cost removes an earned reinforcer after behavior.
Extinction withholds the maintaining reinforcer after behavior.
Answer: A. Noncontingent reinforcement (NCR)
NCR delivers the functional reinforcer according to time rather than contingent on problem behavior, reducing motivation to obtain it through that behavior.
Exam takeaway: NCR is scheduled access to a relevant reinforcer independent of problem behavior.
Question 20 · Task D.3 · Behavior Reduction
The RBT reinforces Maya's raising a hand and waiting instead of calling out. Which differential reinforcement procedure best fits?
Correct: a defined alternative response earns reinforcement.
DRO reinforces periods without the target behavior, not a particular alternative.
DRL reinforces a lower rate of a behavior.
Extinction alone does not describe reinforcement of the replacement.
Answer: A. DRA, including functional communication training when the alternative communicates the same need
DRA reinforces a specified appropriate alternative. When that alternative is communication serving the same function, it is functional communication training.
Exam takeaway: DRA strengthens a specific alternative; FCT is DRA using a communicative response.
Question 21 · Task D.4 · Behavior Reduction
The plan identifies Maya's calling out as attention maintained. During the behavior, what implements attention extinction?
Correct: attention is withheld when attention is the maintaining reinforcer.
Task removal would address escape and might reinforce behavior.
Providing the maintaining event is the opposite of extinction.
Unplanned consequences can alter the intervention.
Answer: A. Withhold the attention that previously followed the behavior while following all safety directions
Function-based extinction withholds the specific reinforcer that previously maintained behavior. Safety and the written protocol remain controlling.
Exam takeaway: Extinction is function specific: withhold the maintaining reinforcer named in the plan.
Question 22 · Task D.5 · Behavior Reduction
After Maya's calling out, the written plan adds a brief corrective task, and the behavior decreases over time. What process is demonstrated?
Correct: a consequence was added and behavior decreased.
Negative punishment removes a stimulus after behavior.
Positive reinforcement adds a consequence and behavior increases.
Negative reinforcement removes a condition and behavior increases.
Answer: A. Positive punishment
A stimulus was added after behavior and future behavior decreased, which defines positive punishment.
Exam takeaway: Positive and negative describe adding or removing; punishment is defined by decreased future behavior.
Question 23 · Task D.6 · Behavior Reduction
Soon after extinction begins, Maya's calling out becomes temporarily more frequent and intense. Which secondary effect is this?
Correct: the behavior escalated temporarily at extinction onset.
Maintenance refers to persistence of a learned skill over time.
Generalization is responding across new conditions.
No new reinforcing stimulus is being established.
Answer: A. An extinction burst
A temporary increase in frequency, duration, or intensity after extinction begins is an extinction burst.
Exam takeaway: An extinction burst is a temporary escalation, not proof that the plan should be changed independently.
During pickup, a parent says the new morning routine is producing fewer refusals. What should the RBT do first?
Correct. Accurate, timely relay preserves the team’s information while keeping clinical decisions with the supervisor.
Incorrect. Changing a behavior plan is outside the RBT’s independent scope.
Incorrect. The RBT should report relevant input rather than acting as the final clinical gatekeeper.
Incorrect. Ordinary team communication should follow the workplace chain of command, not default to a certification-board report.
Answer: A. Record the concern accurately and relay it to the supervisor promptly.
RBTs communicate intervention-team concerns and suggestions to their supervisor in a timely way. They do not independently redesign treatment or filter out information based on their own clinical judgment.
Exam takeaway: Relay team input; do not independently turn it into a treatment change.
During a session, the data sheet has a column the RBT was not trained to score. What is the best next step?
Correct. Timely supervisory direction protects the client and treatment integrity.
Incorrect. Improvising clinical procedures and delaying disclosure can create risk and unreliable implementation.
Incorrect. Caregivers provide important input, but the supervisor directs clinical procedures.
Incorrect. Data irregularities must be reported, not hidden or altered.
Answer: A. Pause the affected procedure as needed and seek timely direction through the supervisory chain.
When training, data, or procedural concerns arise, the RBT seeks and prioritizes timely clinical direction. Safety and the written plan guide what can continue while clarification is obtained.
Exam takeaway: Uncertainty is a signal to seek timely direction, not to improvise or conceal.
At the start of session, the RBT learns that the client slept only three hours. What should the RBT do?
Correct. Objective documentation gives the supervisor context for interpreting performance.
Incorrect. The RBT reports facts and does not make medical or clinical causal diagnoses.
Incorrect. Atypical context is documented; it does not automatically invalidate the data.
Incorrect. Timely reporting is required when a variable may affect progress.
Answer: A. Document the variable objectively and report it to the supervisor in a timely manner.
Illness, medication, schedule, setting, staffing, and material changes can affect progress. The RBT records observable facts and reports them without diagnosing or discarding valid data.
Exam takeaway: Record the context, keep valid data, and avoid causal claims outside your role.
Ethics practice questions
Question 27 · Task F.1 · Ethics
During service, a client communicates that a break is needed. Which action best reflects benefiting others?
Correct. It integrates the four core principles and keeps the client’s interests central.
Incorrect. Convenience does not replace ethical analysis, accurate service, or client protection.
Incorrect. Integrity requires truthful records and conduct.
Incorrect. Ethical responsibility is not transferred to a coworker’s preference.
Answer: A. Protect the client’s interests, respond respectfully, be truthful, and seek appropriate support when needed.
The RBT Ethics Code is grounded in benefiting others; treating people with compassion, dignity, and respect; behaving with integrity; and ensuring competence.
Exam takeaway: Use the core principles together; do not trade integrity or dignity for convenience.
Question 28 · Task F.3 · Ethics
The RBT learns that the listed supervisor’s certification is inactive. What should the RBT do before continuing to practice or bill as an active RBT?
Correct. Practice authority depends on valid status and qualified ongoing supervision.
Incorrect. Familiarity with a client does not replace required supervision.
Incorrect. A caregiver is not automatically a BACB-qualified supervisor.
Incorrect. Missing supervision cannot be retroactively fixed by paperwork.
Answer: A. Pause unauthorized practice, notify the responsible supervisor, and follow certification and workplace rules.
RBT services require close, ongoing supervision from individuals who meet BACB requirements. Certification and supervision status affect whether an RBT may practice, bill, or use the title.
Exam takeaway: No qualified ongoing supervision means no independent RBT practice.
Question 29 · Task F.5 · Ethics
Consider this situation: a neighbor asks whether a child seen entering the clinic is a client. What should the RBT do?
Correct. It protects client status and details while applying the minimum-necessary standard.
Incorrect. A promise does not create authorization or a secure channel.
Incorrect. Context can identify a client even when a first name is removed.
Incorrect. Digital images and messages are confidential records too.
Answer: A. Protect client information; disclose only what is authorized and necessary through approved secure channels.
Confidentiality covers collecting, using, storing, protecting, and disclosing client information across settings and media. RBTs share only authorized, necessary information through approved channels.
Exam takeaway: Even confirming that someone is a client can disclose confidential information.
Question 30 · Task F.7 · Ethics
Outside session, a client’s parent offers the RBT a paid weekend babysitting job. What should the RBT consider first?
Correct. Avoidance, disclosure, and documented mitigation address the relevant risk.
Incorrect. Secrecy increases risk and prevents supervisory safeguards.
Incorrect. Abruptly ending services can harm the client and is not the RBT’s independent decision.
Incorrect. Incidental contact is not automatically a violation, but relevant risk still requires analysis and supervision.
Answer: A. Avoid the added relationship when possible; disclose unavoidable risk and make safeguards with the supervisor.
Multiple relationships can impair objectivity, create conflicts, or risk exploitation. RBTs avoid them when possible and work with supervisors to mitigate unavoidable risks.
Exam takeaway: The issue is risk and conflict—not simply whether two people meet outside session.
