RBT exam.
Think past the term.

The same operational definition is used in two sessions. In Session 1, the technician records 9 calls during 18 observed minutes. In Session 2, the technician records 12 calls during 30 observed minutes. Only observed time belongs in the denominator. Which summary correctly compares calls per minute?

Write the unit before calculating. A larger count can accompany a lower rate when observation time increases.

1. The rate increased, because 12 calls is more than 9.
   Raw counts cannot fairly compare observation windows of different lengths.
2. The rate decreased from 0.50 to 0.40 calls per minute. — Best answer
   9 ÷ 18 = 0.50 and 12 ÷ 30 = 0.40. The count rose while the rate fell.
3. The rate stayed the same, because both sessions included calls.
   The occurrence of a behavior in both sessions does not establish equal rates.
4. The rate decreased from 2.0 to 2.5 calls per minute.
   18 ÷ 9 and 30 ÷ 12 are minutes per call, not calls per minute.

The written whole-interval protocol says to mark “yes” only if on-task behavior occurs throughout the entire 20-second interval. The learner is on task for seconds 0–7, looks away for seconds 7–9, then is on task until the interval ends. What should the technician record?

The recording rule—not the amount of behavior that feels “close enough”—determines the entry.

1. Yes, because the learner is on task at the end.
   An end-of-interval observation would follow a momentary time-sampling rule, not this whole-interval rule.
2. Yes, because on-task behavior occupies most of the interval.
   Whole-interval recording is not a majority-of-time rule.
3. No, because the behavior did not occur throughout the interval. — Best answer
   The two-second interruption means the whole-interval criterion is not met.
4. A blank interval, because the learner switched between behaviors.
   The technician observed the whole interval and can score it. A blank would conceal available data.

Scope / reference: A.2. Mapping is not BACB endorsement or independent validation.

A supervisor wants a permanent-product measure of the number of problems a learner completes independently. The learner and a tutor write on the same worksheet, and their writing cannot be distinguished afterward. What is the best response before using the worksheet as the independent-completion measure?

A permanent product is useful only if it supports the inference you intend to make. Here, authorship and independence are missing.

1. Count every completed problem; the worksheet is a permanent product.
   A durable product alone does not identify who performed the target behavior or whether it was independent.
2. Count half the completed problems as an estimate.
   Dividing by two invents independent-response data.
3. Count only correct problems, regardless of who wrote them.
   Correctness and independence are different features; a correct tutor response is not an independent learner response.
4. Tell the supervisor the product does not distinguish independent learner responses and request a recording arrangement that does. — Best answer
   The measurement needs an identifiable relation to the target behavior. The technician should raise this limitation rather than guess.

Scope / reference: A.3. Mapping is not BACB endorsement or independent validation.

During a supervisor-directed preference assessment, a learner repeatedly selects the spinning top. It has not yet been delivered contingent on a target response. Which conclusion is supported now?

Separate “selected more often” from “increased the response.” Do not promise an effect that was not measured.

1. The top is a preferred candidate; whether it reinforces the target response has not yet been demonstrated. — Best answer
   Selection supports a preference finding. Demonstrating reinforcement requires evidence about the behavior when the item is delivered contingently.
2. The top is a proven reinforcer for every skill.
   Preference does not establish reinforcement for every response.
3. The learner will work for the top in any setting.
   The assessment does not demonstrate effectiveness across settings or changing conditions.
4. No useful information was obtained because no target response was taught.
   The assessment provides information useful for selecting candidates, even though it does not establish reinforcement.

Scope / reference: B.1. Mapping is not BACB endorsement or independent validation.

During a supervisor-directed descriptive assessment, the teacher presents a worksheet, the learner pushes it away, and the teacher removes it for two minutes. The technician has observed this sequence once. Which entry is the most defensible?

An ABC record documents a sequence. Functional conclusions require the supervisor’s assessment and more than an isolated sequence.

1. Function: escape, confirmed by this incident.
   One descriptive sequence does not confirm a functional relation.
2. The learner manipulated the teacher to avoid work.
   “Manipulated” attributes intent rather than describing observable events.
3. Worksheet presented → learner pushed worksheet away → teacher removed worksheet for two minutes; report the observation for supervisor interpretation. — Best answer
   This preserves the observed antecedent, behavior, and consequence without declaring a confirmed function.
4. Attention-maintained behavior, because the teacher responded.
   A response from the teacher does not by itself establish an attention function.

Scope / reference: B.3. Mapping is not BACB endorsement or independent validation.

In the supervisor’s multiple-stimulus-without-replacement procedure, a selected item is removed from the array after brief access. After the learner selects the drum first, the technician accidentally puts it back into the next array. What should the technician do?

Procedural fidelity matters to what the assessment result means. Preserve the error record rather than silently repairing the appearance of the data.

1. Continue and label the assessment MSWO because the first selection was correct.
   Replacing the selected item changes the specified procedure and may change subsequent selections.
2. Document the deviation and ask the supervisor how to handle the affected trial/data before treating the sequence as a valid MSWO ranking. — Best answer
   The deviation should be transparent. The supervisor directs whether and how the affected portion is repeated or interpreted.
3. Delete the drum selection so the remaining sequence looks correct.
   Removing an inconvenient entry conceals the procedural error.
4. Switch to a paired-stimulus assessment without discussing it.
   The technician should not independently substitute a different assessment protocol.

Scope / reference: B.1. Mapping is not BACB endorsement or independent validation.

The written teaching protocol gives the learner five seconds to respond independently, then specifies a gesture prompt if there is no response. On one trial, the technician gestures after two seconds, and the learner responds correctly immediately afterward. How should this trial be handled?

A correct response can still be prompted. Accurate coding protects the distinction between acquisition and independent performance.

1. Score independent because the learner responded before five seconds elapsed.
   The response followed a prompt; the five-second limit does not turn it into an independent response.
2. Score incorrect because every prompted response is incorrect.
   Prompted correctness and an error are not automatically the same category. Follow the specified data definitions.
3. Wait three additional seconds and then relabel the response independent.
   Waiting after a response does not remove the prompt that preceded it.
4. Record the correct response as prompted under the data rules and document the early-prompt deviation. — Best answer
   The record needs to preserve both the prompted response and the deviation from the planned delay.

Scope / reference: C.7. Mapping is not BACB endorsement or independent validation.

A written backward-chaining plan has four steps. The technician assists with steps 1–3, then gives the learner the opportunity to perform step 4 independently. Step 4 meets the plan’s mastery criterion. Which next target follows backward chaining, assuming the supervisor’s plan specifies adding one step at a time?

Follow the direction and progression specified in the written chain. “Backward” concerns which portion is taught first, not performing the activity in reverse.

1. Assist with steps 1–2, then teach the learner to complete steps 3–4. — Best answer
   The independent portion expands backward: the final two steps follow mastery of the final step.
2. Teach step 1 alone while completing steps 2–4 for the learner.
   Beginning with step 1 describes a forward-chaining direction, not this backward-chaining progression.
3. Require independent completion of all four steps immediately.
   That jumps beyond the one-step-at-a-time progression specified in the plan.
4. Continue teaching only step 4 and never add another step.
   Keeping only the mastered final step does not expand the chain.

Scope / reference: C.5. Mapping is not BACB endorsement or independent validation.

The learner requests help independently with one technician using one puzzle. The supervisor’s generalization plan now calls for the same request with a different trained adult and a different puzzle, with the planned response and reinforcement rules unchanged. Which action implements that plan?

Identify the dimension intended to vary. Evidence of transfer requires observing the response under the planned untrained conditions.

1. Repeat the original puzzle with the original technician and call it generalization.
   Repeating the same trained conditions does not implement the requested changes in person and material.
2. Wait several weeks and test only with the original technician.
   A delayed check in the original conditions addresses retention more than the specified transfer probe.
3. Arrange the specified new adult and puzzle, and record performance under those conditions. — Best answer
   This changes the planned people and materials while preserving the relevant teaching rules and collecting evidence.
4. Replace the request with a new phrase and change the reinforcement rule at the same time.
   Changing the target response and reinforcement rule adds variables not specified by the supervisor.

Under a supervisor-written plan, an appropriate break-card request produces a one-minute break. Shouting does not produce that break; the plan includes a separate safety protocol. The learner presents the break card without shouting. What should the technician do?

In this case, the plan supplies the clinical decision. The technician’s task is accurate implementation, not inventing a new requirement.

1. Require the learner to complete an extra worksheet before the break.
   Adding a work requirement changes the specified consequence for the communication response.
2. Provide the one-minute break as specified for the alternative response. — Best answer
   The independent alternative response occurred, so implement its written consequence.
3. Withhold the break because breaks might encourage avoidance.
   Withholding the specified consequence undermines the planned communication contingency.
4. Deliver a preferred toy instead of the planned break.
   A toy is not the functional consequence specified in this plan.

Scope / reference: D.3. Mapping is not BACB endorsement or independent validation.

A supervisor’s written noncontingent-attention procedure schedules brief attention every two minutes, regardless of the target behavior. The technician instead resets the two-minute timer each time the target behavior occurs. What is the key problem?

Ask what starts or resets the clock. That small implementation detail can change the contingency.

1. The reset makes delivery depend on a period without the behavior, so it no longer follows the specified time-based schedule. — Best answer
   The written schedule is independent of the response. Resetting after a response adds a response-dependent requirement.
2. Resetting the timer cannot affect the procedure because attention is still used.
   The contingency, not just the consequence used, defines the procedure.
3. The technician has implemented the written schedule exactly.
   The reset is not part of the given fixed-time procedure.
4. The technician should reset the timer only after especially intense behavior.
   Making resets depend on intensity still changes the specified schedule.

Scope / reference: D.2. Mapping is not BACB endorsement or independent validation.

During a supervisor-authorized behavior-reduction procedure, behavior escalates and meets the written safety plan’s threshold for immediate protective action. The technician has been trained on that safety plan. What is the best next action?

Safety procedures and supervisory direction govern the immediate response. This educational case is not a crisis-management protocol.

1. Ignore the safety threshold because escalation proves extinction is working.
   Escalation does not justify ignoring an explicit safety threshold or prove that an intervention is effective.
2. Create a new restraint technique based on what seems effective.
   The technician must not improvise an untrained restrictive procedure.
3. Continue until the session ends, then mention it in the note.
   The specified immediate response should not be postponed until routine documentation.
4. Implement the trained written safety procedure, obtain the specified assistance, and promptly document/report the event. — Best answer
   The stated threshold calls for the trained safety response and timely communication, not speculation about treatment effects.

Before a session, the caregiver reports that a prescriber increased a medication dose yesterday. The learner appears unusually drowsy during the session. No emergency signs are described. What is the technician’s appropriate documentation and communication?

Use separate language for “caregiver reported” and “technician observed.” Accurate reporting does not require diagnosing a cause.

1. Record the caregiver’s report as a report, describe the observed drowsiness objectively, and communicate promptly through the supervisor’s procedure. — Best answer
   This distinguishes the reported variable from the technician’s observation and brings the concern to the supervisor without prescribing.
2. State that the medication caused the drowsiness and recommend the previous dose.
   Temporal proximity does not prove causation, and medication recommendations exceed the stated technician role.
3. Leave the medication update out because it is outside behavior analysis.
   A relevant reported change may affect progress and should not be omitted solely because the technician does not prescribe.
4. Tell the caregiver to stop the medication until the next session.
   Changing medication is not the technician’s decision.

After an unexpected interruption, the technician discovers that no frequency data were recorded for the final ten minutes. There is no recording or other reliable record from which to recover the counts. Which action is appropriate?

Unknown is not zero. A visible data gap is safer and more informative than an invented precise number.

1. Enter zero, because there is no documented occurrence.
   Zero is a measured absence; missing observation is not evidence of zero occurrences.
2. Use the first ten minutes to estimate the missing count without labeling it.
   An unlabeled estimate creates false observed data.
3. Mark the period as missing according to policy, preserve the recorded data, and promptly tell the supervisor what is and is not known. — Best answer
   The record should distinguish missing data from observed values and disclose the gap for supervisor direction.
4. Delete the whole session so the missing period is not visible.
   Deleting valid observations conceals both useful information and the actual limitation.

The technician drafts: “The learner was defiant and had a terrible session.” Recorded observations show that, after each of three writing instructions, the learner said “no,” pushed the pencil away, and did not begin within the plan’s ten-second window. Which revision best reflects the available observations?

Prefer what was seen, heard, counted, and timed. Objective does not mean omitting relevant context.

1. The learner intentionally refused to cooperate three times.
   “Intentionally” and “cooperate” add inference or ambiguity not present in the observations.
2. After each of three writing instructions, the learner said “no,” pushed the pencil away, and did not begin within ten seconds. — Best answer
   This states the setting, observable responses, count, and specified latency window without attributing motives.
3. The learner was escape-maintained and unmotivated.
   A function and internal state are asserted without the assessment evidence needed to support them.
4. The learner had no successful behavior all day.
   The record describes three opportunities, not the learner’s entire day.

Scope / reference: E.4. Mapping is not BACB endorsement or independent validation.

A caregiver asks the technician to send a client progress graph through the technician’s personal messaging account. The organization requires approved secure channels for client records. The caregiver says, “I give you permission.” What should the technician do?

Permission, authority to disclose, and a permitted transmission method are separate checks.

1. Use the personal account because caregiver permission overrides the organization’s requirements.
   Caregiver permission alone does not make a personal channel compliant with record-handling requirements.
2. Remove the client’s name and send it; all other details are automatically anonymous.
   Removing a name does not necessarily prevent identification or satisfy the approved-channel requirement.
3. Send it now and ask for approval afterward.
   Approval after disclosure cannot undo an unauthorized handling method.
4. Explain that records must use the approved process and coordinate the request through that channel/supervisor. — Best answer
   This respects the request while following the stated confidentiality and organizational process.

The supervisor emails a written protocol for a procedure the technician has never implemented. The technician has not practiced it or demonstrated competence. The next session is tomorrow. What is the best next step?

Being assigned a procedure does not by itself establish readiness to deliver it competently.

1. Implement independently because written instructions establish competence.
   Reading instructions alone is not a demonstration of implementation competence.
2. Tell the supervisor about the training need and arrange the required training/competence check before implementing independently. — Best answer
   Disclosing the limitation allows appropriate training and verification rather than unsupported independent implementation.
3. Ask a caregiver to teach the procedure during the session instead.
   The case does not establish the caregiver as an authorized trainer or a substitute for supervisor-directed competence verification.
4. Use a different familiar procedure without informing the supervisor.
   An unauthorized substitution changes the clinical plan and conceals the training need.

A caregiver offers the technician paid weekend babysitting for the same client. The technician has not accepted. No emergency is involved. What is the best response?

Look at the overlapping roles, not just whether an activity is called therapy. Raise potential conflicts before agreeing.

1. Accept because babysitting occurs outside paid therapy hours.
   A second paid caregiving role can create a multiple relationship regardless of the time of day.
2. Accept if no therapy data are collected while babysitting.
   Avoiding data collection does not remove the second role or its possible conflicts.
3. Do not commit; explain the professional boundary and promptly discuss the potential multiple relationship with the supervisor under the organization’s policy. — Best answer
   This raises the potential conflict before entering the arrangement and uses supervisory/policy guidance.
4. Accept but keep the arrangement private to avoid concern.
   Secrecy prevents appropriate management of the potential conflict.
