Free RBT Practice Exam — 85 Questions, BACB-Aligned 2026

Variables that affect client performance (sleep, food, medication, illness, life events) must be documented because they help the team interpret data accurately. Without this context, the supervisor might conclude the program is no longer effective. Reporting to the supervisor ensures the team can plan accordingly (e.g., not concluding regression based on one off day).

Confidentiality applies to ALL unauthorized people, including family members not on the authorization. Family status does NOT grant access to clinical information unless explicitly authorized. The RBT should politely decline and redirect to authorized channels. This protects client privacy and protects the RBT and agency from privacy violations.

Objective documentation describes observable, measurable behaviors with specific counts and contexts. Option B specifies topography (verbal protest), provides a count (6 protests), and quantifies task completion (2 of 8). Options A, C, and D use subjective interpretive language ('upset,' 'unmotivated,' 'difficult,' 'meltdowns,' 'refused because... tired') that infer internal states.

Forward chaining builds from the FIRST step forward — best when the learner has the first step and you can shape subsequent steps. Backward chaining is often preferred when reinforcement from task completion is needed every trial (the learner finishes the chain on every trial). Total task is preferred when the learner has partial competence across multiple steps.

Momentary time sampling records only at interval endpoints. When a behavior occurs in brief bursts separated by long pauses, the bursts are likely to occur BETWEEN endpoints and be missed, leading to underestimation. Momentary sampling is poor for low-frequency, short-duration behaviors. Partial-interval would tend to overestimate the same behavior.

Programming for stimulus generalization across exemplars (objects) requires explicit training with multiple exemplars within the relevant stimulus class. 'Training loosely' or multiple-exemplar training builds responding across the desired class. Training in one setting limits generalization. Restricting to one SD type is the opposite of programming for generalization.

Prompt dependence is a known risk when prompts are not faded systematically. The remedy is structured prompt fading — time delay, graduated guidance, or systematic prompt-level reduction. Maintaining the prompt or switching to a different intrusive prompt does not address the underlying issue: failure to transfer stimulus control from prompt to natural SD.

Latency measures the time from an antecedent stimulus (such as an instruction) to the onset of the response. Reducing the delay between an instruction and a response (compliance latency) is a typical clinical target. Option A is duration. Option C is IRT. Option D is rate.

Schedule thinning (moving from richer to leaner schedules) is a standard procedure that builds resistance to extinction and prepares the behavior for natural contingencies in everyday environments, where reinforcement is rarely continuous. VR schedules produce particularly persistent behavior. Extinction would mean stopping reinforcement entirely.

Medication administration is OUTSIDE the RBT's scope of practice and outside the role of a behavior technician. It is a medical activity requiring different training and licensure. Family request does NOT change scope of practice. The RBT should decline regardless of supervisor approval, because supervisors cannot expand the RBT's scope beyond what BACB allows.

Whole-interval recording requires the behavior to occur throughout the entire interval — so it is well-suited to behaviors the team wants to INCREASE that should be sustained (engagement, on-task, attending). It would systematically UNDERESTIMATE brief or intermittent behaviors. For increasing a continuous behavior, you want a sensitive measure of sustained engagement.

Session notes should document what was done (procedures), what was observed (client responses, behavioral data), and contextual variables. Opinions, speculation, and predictions are not appropriate. The RBT's role is to provide objective data for the supervisor's clinical decisions, not to offer clinical interpretations.

Interval-by-interval IOA counts intervals where observers agree on the exact same value. Comparing: disagree (3≠2), agree (2=2), agree (0=0), disagree (1≠2), disagree (4≠3), agree (0=0), agree (2=2), agree (1=1), disagree (3≠2), disagree (0≠1). Agreements: 5 out of 10 = 50%. (Smaller-over-larger or total-count IOA would yield different values.)

Extinction may be contraindicated when (1) safety risk during the extinction burst is unacceptable (dangerous aggression or self-injury that cannot be safely allowed to escalate), or (2) the function cannot be reliably controlled. For dangerous behaviors, antecedent intervention, DRA combined with extinction, or other procedures are often safer. Extinction is theoretically appropriate for any function but requires that the maintaining contingency can be withheld safely and consistently.

FCT is a DRA-based procedure that teaches a communication response (verbal, sign, picture exchange, AAC) that produces the same functional reinforcement as the problem behavior. For example, teaching a learner to ask for a break to replace escape-maintained problem behavior. FCT is one of the most effective and ethical behavior reduction approaches.

BACB requires ongoing supervision for RBT service delivery. A 6-week gap is a serious issue. The RBT must escalate the situation through proper channels — agency, then BACB if necessary — and may need to pause direct service delivery until supervision is restored. Continuing without supervision risks both the RBT's certification and client safety.

Changing documentation to misrepresent service time is FRAUD — a serious legal and ethical violation. Documentation must reflect what actually occurred. The RBT must refuse the request and report it through appropriate channels (supervisor, ethics officer, compliance line). This is a documented BACB ethics issue and may be a reportable violation.

NCR delivers reinforcement on a time-based schedule (fixed-time or variable-time) regardless of what the learner is doing. It is often used as an antecedent intervention for attention-maintained or tangible-maintained behaviors because it reduces the motivation for problem behavior. It is NOT contingent on any particular response.

A familial or romantic relationship between supervisor and supervisee creates a multiple relationship that compromises supervision integrity, evaluation objectivity, and professional boundaries. This is an ethically problematic dual relationship that must be disclosed immediately and resolved (typically by reassigning supervision). Continuing the arrangement, even 'carefully,' is inappropriate.

DRO reinforces the ABSENCE of a specified target behavior — it does NOT specify a particular alternative behavior. Reinforcing for completing a math worksheet is DRA (or simply reinforcement of completion), not DRO. DRO is used to reduce specific behaviors by reinforcing periods of non-occurrence regardless of what else the learner does.

The interventions described (graduated task difficulty, frequent breaks, reinforcing break-requests) are antecedent-based and target the escape function of the behavior. The plan addresses the MO for escape (difficult demands) before the behavior occurs. It is function-based because it directly addresses the maintained reinforcer (escape) rather than just topographically targeting the behavior.

Motor imitation (sometimes called 'duplicative motor behavior') is controlled by a non-verbal SD (the model's movement) with point-to-point correspondence. Echoics are vocal duplication of verbal stimuli. Mands are under motivating operation control. Listener responding is following verbal instructions for non-imitative actions.

A STABLE, LEVEL baseline (low variability, no trend) is essential for evaluating intervention effects — without it, you cannot rule out alternative explanations for change. The baseline here is admirably stable. Mean differences alone don't establish intervention effects; trend, level, and variability all matter. Baseline length is determined by stability, not a fixed number of sessions.

IRT measures the time between successive instances of the same behavior. The times given (4:02 → 4:09 → 4:14 → 4:20 → 4:31) describe the gaps BETWEEN behaviors — that is IRT data (7, 5, 6, 11 minutes). Latency is time from antecedent to response onset. Duration is how long each episode lasts. Rate is frequency over time.

When behavior has multiple functions, each must be addressed for the BIP to be effective. For example, an attention function might be addressed with DRA + extinction for attention; the escape function might be addressed with functional communication training (FCT) for breaks. Addressing only one function leaves the behavior reinforced by the other and recovery is likely.

DRO interval thinning should be GRADUAL — typically 25-50% increases at a time — to maintain success and avoid losing the behavior change. Jumping from 2 minutes to 30 minutes is too aggressive and risks the learner failing the interval and the procedure becoming aversive. Decreasing to 10 seconds would be regression.

RBTs must implement BIPs as written by the supervisor — modifying plans independently violates scope of practice. The appropriate channel for clinical concerns is to discuss them with the supervisor. The RBT may share observations and ideas through proper channels but does not unilaterally alter clinical procedures. Following the chain of command is core to RBT ethics.

BST builds skills under specific training conditions but does not automatically produce generalization. When a skill is acquired in training but doesn't generalize, the team must explicitly program for generalization — training across multiple exemplars, people, and settings. This is a known limitation of BST without generalization programming.

A general response-prompt hierarchy from MOST to LEAST intrusive: full physical → partial physical → verbal → gestural → independent. Gestural prompts (pointing, nodding) are typically considered less intrusive than verbal because they require less verbal processing and are easier to fade. The exact hierarchy can vary slightly by source and learner.

DTT is a highly structured teaching format characterized by: discriminative stimulus (SD) → prompt if needed → response → consequence (reinforcement or correction) → intertrial interval (ITI). It is well-suited for acquisition of discrete skills. NET uses naturalistic opportunities — the opposite design.

Stimulus overselectivity (narrow stimulus control) occurs when the learner's response is controlled by an irrelevant feature of the SD (the specific font, color, or background) rather than by the relevant feature (the letter shape). It is common in early learners and is remedied by training with multiple exemplars to broaden the relevant stimulus class. Discrimination failure would mean responding to all letters equally.

Unexplained injuries must be documented OBJECTIVELY (no inferences about cause) and reported PROMPTLY to the supervisor — same session if possible — so the supervisor can determine next steps including mandated reporting obligations. RBTs should NOT interrogate clients (which can be re-traumatizing) and should NOT photograph clients (privacy and legal complications).

Extinction often induces novel behaviors as the learner 'searches' for ways to produce reinforcement — sometimes called response variability or burst with novel topographies. The new behaviors should be evaluated for function: if they are functionally equivalent to the original target (also escape-maintained), they should also be placed on extinction. This is why function-based intervention is critical.

Least-to-most prompting begins with NO prompt and provides INCREASING levels of assistance only as needed. The trial starts with an opportunity for the independent response, then adds the least intrusive prompt if needed, then more intrusive if still no response. Most-to-least starts with the most intrusive prompt and fades down.

Compromising assessment validity by using prompts (which artificially boost scores) or marking unattempted items as incorrect both produce invalid data. The RBT should document objectively what happened, pause the assessment, and let the supervisor decide how to proceed. Marking items inaccurately is also a documentation/integrity issue.

Motivating operations (EOs/AOs) change the value of reinforcement and the frequency of behavior that produces it. Discriminative stimuli (SDs) signal that reinforcement is available in their presence — they do not change reinforcer value, only availability. Both can be conditioned or unconditioned. Both occur before behavior. RBTs work with both.

Behaviors reinforced on intermittent schedules show greater RESISTANCE TO EXTINCTION than behaviors reinforced on CRF. This is sometimes called the partial reinforcement extinction effect (PREE). It is why we thin schedules during teaching — to build behavior that persists in natural environments where reinforcement is rarely continuous.

Reactivity is a measurement issue where the act of observation itself produces a change in the observed behavior. It threatens the validity of data because the data may not reflect typical performance. Option A is extinction burst. Option C is observer drift / interobserver disagreement. Option D is generalization.

Gifts from clients/caregivers — especially CASH — create multiple relationships and ethical violations. The RBT should politely decline and explain the ethical reasoning. The caregiver's intent does not change the ethical issue. Even small amounts of cash are problematic because they create a financial relationship outside the professional one.

Insurance fraud is a serious legal and ethical violation that the RBT is OBLIGATED to report through appropriate channels (not direct confrontation, which can compromise investigation). Many agencies have compliance hotlines for this purpose. Failing to report makes the RBT complicit in the violation. Confronting directly is generally inappropriate for fraud allegations.

Stimulus prompts are added to or change the SD ITSELF (size, color, position, intensity). Response prompts are added to the learner's RESPONSE (physical guidance, verbal model, gestural cue). Moving the learner's hand is physical guidance — a response prompt. The other three are stimulus prompts (size, color, position).

On a CUMULATIVE record, a flat slope means no (or very few) new responses are being added — the learner is responding at a very low rate. A flat cumulative curve does NOT indicate regression (the previous responses remain summed). Mastery would not show on the cumulative graph as flatness — it would still rise with each correct response.

Operationalizing means converting vague language ('aggressive when frustrated') into observable, measurable terms (specific topographies, specific antecedents, specific contexts). Options C and D are useful follow-ups but less primary than first making the behavior measurable. Option B skips the assessment step entirely. The RBT's role is to gather observable, measurable information.

Paired-stimulus assessment systematically counterbalances item position across trials (each item appears on the left and right equally often), controlling for position bias. MSWO with random positioning helps but doesn't guarantee position counterbalancing. Free-operant doesn't use selection at all but measures engagement. Single-stimulus doesn't compare items.

An intraverbal is a verbal response controlled by other verbal stimuli (without point-to-point correspondence). The parent's question ('What barks?') is the verbal antecedent, and the answer ('doggy') is the verbal response. It is NOT controlled by the dog being present (which would be a tact). Echoics are direct repetitions; mands are under motivating operation control.

Spontaneous recovery is the temporary reappearance of an extinguished behavior after a period of non-occurrence — it is a well-known and expected pattern during extinction. Continued application of extinction will resolve it. Re-introducing reinforcement would REINFORCE the recovered behavior and undo extinction progress.

Continuous measurement captures every instance of behavior — frequency, duration, latency, IRT, and permanent product (counting outcomes after the fact still captures every instance). All interval and time-sampling methods are DISCONTINUOUS — they sample behavior and only estimate occurrence. Permanent product is the only continuous method listed.

Preferences are not static — motivating operations (deprivation, satiation, novelty) shift over time, so preference assessments are routinely repeated to ensure that identified reinforcers remain effective. A consistently selected item is a strong preference signal, NOT an indicator of invalid assessment.

A mand is controlled by a motivating operation (deprivation) and produces direct reinforcement (the cookie). A tact is controlled by a nonverbal SD (seeing the cookie) and produces social reinforcement (praise). The same word ('cookie') can serve different verbal operant functions depending on what controls it. Skinner's classification is functional, not topographical.

When occurrence-only IOA is substantially lower than total IOA, observers tend to agree about NON-occurrence (which inflates total IOA) but disagree about whether and when the behavior is occurring. This is critically important to identify because the agreement on what matters most (the behavior itself) is weak. Total IOA can be misleadingly high when behaviors are rare.

Billing for time not actually spent on covered activities is fraud, even if it's a small amount. Personal errands during a gap are not billable. The RBT must accurately document only the time actually spent traveling or providing service. The agency policy doesn't authorize billing for personal time.

Rate = frequency ÷ time. 8 occurrences ÷ 20 minutes = 0.4 occurrences per minute. Option C describes mean duration per episode (32.5 sec average), and Option D describes total duration (260 sec total). Option A is the count only without a time dimension.

Late entries are acceptable WHEN clearly identified as such with the actual date and time of entry. Backdating documentation to look as if it were completed at a different time is a form of falsification and is a serious ethical and potentially legal violation (especially for billing purposes). The integrity of the record is more important than appearance of perfect compliance.

Cancellations and missed sessions must be documented promptly with the reason, notification details, and any communication with the family. This is required for clinical continuity, billing integrity, and compliance. Failing to document missed sessions can create documentation gaps that lead to compliance issues and undermine clinical record integrity.

BST has four components delivered in sequence: (1) instruction (verbal or written), (2) modeling (demonstration of correct performance), (3) rehearsal (the learner practices), and (4) feedback (positive and corrective). BST is widely used to train RBTs, parents, and caregivers in implementing procedures with fidelity.

Maintenance probes assess INDEPENDENT performance of a previously mastered skill without prompts or active teaching, to determine whether the skill persists over time. Re-training or co-performing would not measure maintenance. Maintenance probes typically use the same task analysis to ensure comparability with mastery data.

Brief, polite acknowledgment is appropriate — pretending not to see them is rude and unrealistic in small communities. Extended social interaction, especially discussing the client or clinical matters in public, creates boundary issues and confidentiality risks. The professional standard is brief acknowledgment without extended engagement or clinical discussion.

A time-of-day pattern is a starting point for hypothesis generation — the next step is to investigate what variables are present at that time (specific instruction, specific people, specific demands, sensory environment). Scatter plot data alone does NOT establish function; it points to where to look. Implementing intervention without further assessment skips the most important step.

Functional analysis (FA) systematically manipulates conditions to test hypotheses about behavior function — this experimental method provides the strongest causal evidence about function. Indirect assessment relies on report (weaker). Descriptive assessment correlates antecedents/consequences with behavior but cannot establish causation. RBTs DO NOT conduct functional analyses independently — they assist as directed.

Antecedent interventions modify variables BEFORE the behavior occurs, preventing it rather than responding to it. They are generally less intrusive, do not require the learner to experience the problem behavior repeatedly, and address root causes (e.g., task difficulty, environmental triggers) rather than just consequences. They are clinically preferred when feasible. All behavior plans require supervisor design.

Burnout that compromises clinical quality is an ethical issue — RBTs have an obligation to maintain competent practice. Ignoring burnout to maintain attendance creates risk for clients. The professional path is to acknowledge the issue with the supervisor and work toward sustainable adjustments. Self-care is part of professional responsibility, not optional. The BACB Ethics Code addresses this directly.

DRL is used to REDUCE the rate of an appropriate behavior — not eliminate it. Classic examples: a student raising their hand too often during class (appropriate behavior, excessive rate); a learner asking for breaks too frequently. DRL reinforces the behavior when it occurs at or below the target rate. For complete elimination, DRO is used. For dangerous behavior, more direct procedures are needed.

Token economies typically fail when the BACKUP REINFORCER (what tokens are exchanged for) loses motivating value due to satiation, changed preferences, or new motivating operations. Updating the backup reinforcer (often by repeating a preference assessment) usually restores the system's effectiveness. The other options describe much less common causes.

Objective documentation uses observable, measurable language about what the RBT directly saw and heard. Subjective documentation uses interpretive language ('was angry,' 'seemed sad,' 'probably tired,' 'refused because...'). Behavioral records should be objective; clinical interpretations belong in supervisor consultation, not RBT session notes.

ABC recording is a DESCRIPTIVE assessment of the natural environment — the goal is to identify the antecedents and consequences that typically occur. If the observer intervenes, those interventions become the consequences instead of the natural ones, defeating the purpose of the assessment. This is a fundamental methodological constraint of descriptive assessment.

Deprivation (no water for 2 hours) is a classic EO — it increases the value of water as a reinforcer and increases behaviors that produce water. Option A is the SD (the cookie itself). Option C is the SD (token board signals availability). Option D is the reinforcer delivery.

DRI is a SUBSET of DRA — it specifies that the reinforced alternative must be physically incompatible (cannot occur at the same time) with the target behavior. DRA can reinforce any functionally appropriate alternative, including some that are not physically incompatible. The 'I' in DRI emphasizes the physical incompatibility constraint.

Backward chaining adds one step BACKWARD at a time. After mastering step 8 independently, the next phase requires the learner to independently perform steps 7 AND 8 (still with the RBT physically performing steps 1-6). This progressively builds the chain from end to beginning, giving the learner the reinforcement of completing the task every trial.

Behaviors reinforced on CRF extinguish FASTER than those reinforced on intermittent schedules — this is the partial reinforcement extinction effect (PREE) in reverse. CRF makes the absence of reinforcement very salient, while intermittent reinforcement has trained the learner to persist through periods without reinforcement. This is one reason schedule thinning is part of effective intervention.

CRF (reinforcing every correct response) accelerates initial learning by maximizing the contingency between behavior and reinforcement. As the skill is acquired, the schedule is thinned to intermittent (VR or VI) to build resistance to extinction and promote maintenance. CRF is contraindicated in maintenance because it makes the behavior fragile to extinction when reinforcement is naturally intermittent.

Client documentation contains protected health information (PHI). Personal Gmail (and most personal email) is NOT HIPAA-compliant. The RBT must direct the caregiver to the agency-approved secure portal. Sending PHI via personal email is a HIPAA violation regardless of how it's labeled. The RBT may notify the supervisor about the request so the agency can address the portal issue.

Errorless learning prevents errors by delivering the prompt IMMEDIATELY upon SD presentation, before the learner has time to respond incorrectly. Most-to-least prompting starts with high assistance and fades. Waiting for an error and then prompting is least-to-most (the opposite approach). Telling the answer aloud is a verbal prompt but doesn't follow the most-to-least, errorless framework.

When access to a reinforcer is excessive within a short time, the value of the reinforcer decreases — this is an abolishing operation (specifically, satiation). The learner is no longer motivated to request because the value of the request's outcome has decreased. Extinction would mean reinforcement was no longer being delivered; here it still is.

Stimulus equivalence is a derived relational responding phenomenon: after learning some relations (e.g., A=B and B=C), the learner demonstrates untrained relations (A=A reflexivity, B=A symmetry, A=C transitivity). It is an advanced concept that explains how learners derive untaught relations and is foundational to many language and reading programs.

Without proper authorization (typically a signed Release of Information), the RBT cannot share client information with other providers regardless of how legitimate the coordination of care seems. Verbal approval by phone is insufficient — written authorization is required. The professional path is to facilitate authorized sharing through proper releases.

Confidentiality requires that an RBT not CONFIRM, ACKNOWLEDGE, or DISCUSS any client information with unauthorized people in any setting. Even confirming that a person is a client is a confidentiality violation. The professionally appropriate response is to politely decline and redirect. Suggesting the person ask the parents implies confirmation of the client relationship.

Stimulus generalization across PEOPLE is a specific type of generalization — the SD should evoke the response regardless of who delivers it. Failure here means the response is under the stimulus control of the original RBT specifically, not the generalized SD. The team would program for generalization by training with multiple instructors. Maintenance refers to time-based persistence.

Progressive time delay gradually INCREASES the delay between SD and prompt across trials (0s → 2s → 4s → 6s → ...). Constant time delay uses ONE delay value across many trials (e.g., always 4 seconds after initial 0s trials). Both are time-delay procedures used to transfer stimulus control from prompt to SD.

Partial-interval recording yields a PERCENTAGE OF INTERVALS measure — it cannot tell you the exact count of behavior, because multiple occurrences within an interval are scored the same as a single occurrence (and brief inter-interval occurrences are missed). Frequency is what cannot be recovered from partial-interval data. All the other options ARE derivable from partial-interval data.

Educational placement decisions involve multiple disciplines (special education, school psychology, sometimes BCBAs) and are well outside the RBT's scope of practice. The RBT may report observations to the team but should not offer opinions on educational placement. Directing the parent to the appropriate decision-makers (educational team + BCBA) is the professional response.

Variability refers to the degree of fluctuation in data points. These scores range from 30% to 95% with no consistent direction across sessions — that is HIGH VARIABILITY with no clear trend. Trend describes systematic direction; level describes the mean position. High variability makes it difficult to detect intervention effects and may indicate measurement error or uncontrolled variables.

Momentary time sampling (recording only at the END of each interval) is the LEAST resource-intensive method and works well when continuous observation is not possible — which applies here because the RBT is also delivering instruction. Whole-interval would require continuous observation throughout each interval. Frequency requires discrete behaviors with clear onset/offset, which isn't true for on-task behavior.

Total task chaining presents the entire chain on every trial with prompts as needed, and is best suited when the learner has at least partial competence across most steps (so prompts are needed only for specific weak steps). For learners with no competence, forward or backward chaining provides more structure. Backward chaining is best for trial-by-trial completion reinforcement value.

Free-operant preference assessment provides free access to items and measures engagement duration — it is the most useful method for learners who cannot or will not select items from a structured array. It is more naturalistic but slower than MSWO. Paired-stimulus and MSWO require reliable selection responses. Free-operant doesn't yield a strict preference ranking the way MSWO does.

Increased intensity early in extinction (an extinction burst) is a known and expected pattern that resolves as the extinction procedure continues. Discontinuing or modifying the BIP at this point would actually REINFORCE the intensified behavior. The RBT must continue as written, document the pattern, and report to the supervisor for guidance.

ABC recording documents the Antecedent, Behavior, and Consequence for each observed behavior. Descriptive method that generates hypotheses about function but doesn't experimentally test them. Function analysis (FA) does experimentally test function. → Study this topic

Rate = frequency ÷ time. 45 ÷ 90 minutes = 0.5 per minute. Always include the time unit when reporting rate (0.5 per minute, not just 0.5). This standardizes comparison across sessions of different lengths. → Practice questions

RBTs are typically mandated reporters under state law. Suspected abuse or neglect must be reported IMMEDIATELY through proper channels — not after asking parents, not after gathering more evidence, not requiring child confirmation. Failure to report is a legal violation. → Study this topic

Extinction requires withholding the reinforcer that maintains the behavior. For automatic (sensory) reinforcement, the reinforcer is produced by the behavior itself and can't be withheld externally. Different strategies (like sensory extinction devices or DRA) are needed. → Study this topic

Social media connections with client families create boundary concerns. Even innocent posts can create multiple relationships or unintentional disclosure of client information. Professional distance should be maintained on personal social media. → Study this topic

Scatter plots identify TEMPORAL patterns — when behavior tends to occur across time periods. They do NOT identify function or severity. Temporal patterns can generate hypotheses (e.g., before lunch = hunger; specific activity = escape). → Study this topic

NET (Naturalistic Environment Teaching) embeds instruction into naturally-occurring routines and play, using the learner's existing motivation. It's most effective when learners have strong motivation in natural contexts. DTT would be structured trials; shaping reinforces approximations; errorless learning uses immediate prompts. → Practice questions

Client-to-staff injuries require agency incident reports. This creates documentation for insurance, safety analysis, and BIP updates. Verbal reports alone are insufficient — written documentation is required. → Practice questions

Fixed ratio (FR) schedules deliver reinforcement after a specific number of responses. FR-5 means every 5th response earns reinforcement. This differs from variable ratio (average number varies) and fixed interval (based on time, not responses). → Study this topic

Whole-interval recording UNDERESTIMATES behavior. If behavior occurred for 29 out of 30 seconds, that interval is still scored as 'no occurrence' because it didn't cover the entire interval. Useful for on-task or engagement measures. → Study this topic

Functional Analysis (FA) is the gold standard for determining behavior function. It experimentally manipulates conditions to test hypotheses about what maintains the behavior. RBTs assist by implementing conditions and collecting data. → Study this topic

Total count IOA = smaller ÷ larger × 100. 20 ÷ 25 = 0.80 = 80%. Total count IOA is one of several IOA methods; interval-based IOA methods (like exact agreement per interval) provide more stringent measures. → Study this topic

NET works best when learners have low motivation in structured DTT settings but strong motivation during natural activities like play. Embedding teaching into play captures existing motivation rather than trying to establish it artificially. → Practice questions

Program modifications are the BCBA's responsibility, not the RBT's. The RBT should document the parent's request and communicate it to the BCBA, who will decide whether/how to modify the program. → Study this topic

When ethical concerns arise, consult the BACB Ethics Code and discuss with the supervising BCBA. Ethical decision-making should be systematic, not based on personal judgment alone. Documentation of the consultation is also recommended. → Study this topic

In MSWO (Multiple Stimulus Without Replacement), the chosen item is REMOVED from the next array. Positions of remaining items are rotated to control for position bias. This continues until all items are chosen or the learner stops selecting. → Study this topic

Indirect functional assessment uses interviews and questionnaires (MAS, FAST, PBQ) with people who know the client. Generates hypotheses but doesn't directly observe or manipulate behavior. Often the first step in the assessment process. → Study this topic

Ethical concerns about a supervisor's fitness for duty must be reported through appropriate channels (agency HR, BACB, etc.). Client safety and ethical practice are paramount. The RBT is protected when reporting in good faith. → Study this topic

Duration measures how long each instance of behavior lasts (end time − start time). Useful when the length of behavior matters (e.g., tantrums, on-task behavior). Different from frequency (how often), rate (frequency ÷ time), and latency (SD to response). → Study this topic

Interpretation of assessment results is within the BCBA's scope of practice, not the RBT's. The RBT should politely refer the parent to the BCBA. RBTs implement plans as designed; they don't design or interpret them. → Study this topic

The behavior only occurs in the presence of demands and is reinforced by their removal. This is escape-maintained behavior. Intervention would typically involve continuing to present demands while teaching a functional alternative (like requesting a break). → Study this topic

Momentary time sampling checks behavior only at the END of each interval (or another single moment). Useful when the RBT can't continuously observe. Less accurate than continuous methods but practical for group settings. → Study this topic

Crisis procedures must be followed EXACTLY as trained and specified in the BIP. Improvisation during a crisis can put the client and staff at risk. Documentation after the incident is also required. → Study this topic

Stimulus prompts modify the SD itself (position, size, color, brightness). Response prompts are added to the learner's response (physical guidance, verbal prompts, models, gestures). Moving the correct card closer manipulates the stimulus array — a stimulus prompt. → Study this topic

Backward chaining teaches the LAST step first, allowing the learner to experience task completion (and reinforcement) on every trial. The remaining earlier steps are prompted until independence works backward. → Study this topic

Constant time delay uses the same delay value on every trial (e.g., 4 seconds). Progressive time delay gradually increases the delay over trials (0, 2, 4 seconds, etc.). Both give the learner a chance to respond independently before prompting. → Study this topic

Least-to-most prompting starts with no prompt and adds prompts only when the learner fails to respond. This encourages independent responding but does allow errors. → Study this topic

RBT renewal requires: renewal application, documentation of ongoing supervision, and renewal fee. The 40-hour training is ONLY required at initial certification, NOT for renewal. Many candidates get this wrong on the exam. → Study this topic

Even without a name, mentioning a client on social media violates confidentiality. HIPAA covers any information that could identify a client. Social media should never reference specific client interactions, sessions, or details. → Study this topic

Permanent product recording measures the lasting physical effect of behavior (completed worksheets, assembled items). Requires the product to remain intact for review. Efficient because it doesn't require continuous observation. → Study this topic

The high-probability sequence (behavioral momentum) presents 3-5 easy demands the learner reliably completes, building 'compliance momentum,' then presents the difficult demand. This antecedent strategy increases the likelihood of compliance with the target demand. → Study this topic

Medication changes and other variables (illness, sleep, family events) may affect behavior. RBTs should document and report these to the BCBA so they can be considered when interpreting data. The RBT doesn't interpret medical effects — the BCBA/team does. → Study this topic

DRO (Differential Reinforcement of Other behavior) reinforces the ABSENCE of the target behavior for a defined interval. The RBT sets a timer and delivers reinforcement if the interval passes without the behavior occurring. → Practice questions

Stimulus generalization occurs when a learned response transfers to new stimuli (new setting, new time, new materials). Response generalization is when the topography of the response varies. Maintenance is behavior persisting over time. → Study this topic

Expensive gifts create ethical concerns (multiple relationships, appearance of impropriety). Most agencies have specific policies — typically declining gifts above a small value ($20-25). The offer should be documented per policy. → Study this topic

Session notes must be objective and factual. Personal opinions about mood ('the client seemed sad') are subjective inferences, not observations. Include what was directly observed (behavior, procedures, data) — not inferences. → Study this topic

The parent has disclosed the relationship, but the RBT should not add clinical details or discuss the client. Polite acknowledgment maintains dignity and confidentiality without being rude. Never confirm diagnosis or clinical information in public settings. → Study this topic

Rotating positions prevents the learner from learning 'always pick the left card' instead of actually discriminating between the items. Position bias is a common learning artifact in discrimination training — position rotation controls for it. → Study this topic

A mand is a verbal operant controlled by a motivating operation (wanting something). The child wants the cookie and is requesting it. The consequence is direct access to the item. Tacts are controlled by seeing something and produce social reinforcement. → Study this topic

Client information should never be discussed in public spaces (coffee shops, elevators, restaurants) — regardless of volume. HIPAA requires reasonable safeguards. Ask the coworker to use an authorized communication channel later. → Study this topic

Frequency recording is CONTINUOUS — it records every occurrence of behavior. Partial-interval, whole-interval, and momentary time sampling are DISCONTINUOUS (sample behavior in intervals). Rate, duration, and latency are also continuous methods. → Study this topic

Reinforcement should be delivered IMMEDIATELY after the target response (within 1-2 seconds) to establish a strong contingency. Delays weaken the relationship between behavior and consequence, potentially reinforcing whatever behavior occurred just before delivery. → Study this topic

DRI (Differential Reinforcement of Incompatible behavior) reinforces a behavior that physically cannot co-occur with the target behavior. Folded hands are physically incompatible with hair-pulling. This is what distinguishes DRI from DRA. → Study this topic

Errorless learning uses immediate prompts to prevent errors during acquisition, then systematically fades the prompts. This approach reduces the reinforcement history for incorrect responses and can accelerate learning for some learners. → Study this topic

DRL (Differential Reinforcement of Low rates) reduces an appropriate behavior that's occurring too frequently. The goal is not to eliminate the behavior but to bring it to an acceptable rate. Different from DRO, which reinforces absence. → Study this topic

Partial-interval recording OVERESTIMATES behavior because a single brief occurrence marks the entire interval as 'behavior occurred.' Whole-interval recording underestimates (requires the entire interval). Momentary time sampling checks only at interval endpoints. → Study this topic

The primary purpose of a preference assessment is to identify items that MAY function as reinforcers. Items identified as preferred must still be tested in a reinforcer assessment to confirm they actually increase behavior. → Study this topic

RBTs must maintain ongoing supervision by a qualified BCBA. Providing services without active supervision violates BACB requirements and could invalidate certification. A backup supervisor must be arranged during any extended absence. → Study this topic

Maintenance is a skill persisting over time without active teaching. Generalization is transfer across stimuli. Fluency is rate + accuracy. Acquisition is initial learning. Maintenance probes are typically scheduled weeks or months after mastery. → Study this topic

The RBT should correct the method going forward, honestly document the collection error, and notify the supervisor. Fabricating data is a serious ethical violation. Transparent documentation lets the BCBA account for the error in program decisions. → Study this topic

Stimulus control transfer means control of the response has moved from the prompt (verbal model) to the natural SD (seeing the ball, wanting to label it). This is the goal of prompt fading procedures. → Study this topic

Client information cannot be discussed in public settings — regardless of volume. This is a HIPAA and BACB ethical violation. The RBT should firmly decline and suggest discussing later in an authorized setting. → Study this topic

An extinction burst — temporary increase in intensity, frequency, or duration — is EXPECTED when extinction begins. The RBT must continue as written. Stopping now would reinforce the more intense behavior and make it worse. → Study this topic

Client dignity must be maintained in all communications. Use objective, respectful language. Avoid demeaning terms even when describing challenging behaviors. Recommendations about placement or treatment are BCBA responsibilities. → Study this topic

When materials are missing, the RBT should contact the supervisor and use approved backup methods (e.g., generic data sheets, agency-approved alternatives). Improvising or skipping programs without authorization violates procedural fidelity. → Study this topic

DTT requires a clear inter-trial interval (ITI) between trials — typically 3-5 seconds. The ITI helps the learner discriminate between separate teaching opportunities and prevents runaway responding. Skipping the ITI degrades the discriminative properties of the SD. → Study this topic

A tact is a verbal operant controlled by a nonverbal stimulus (seeing the dog picture). The consequence is typically social reinforcement (praise), not direct access to the item. This distinguishes tacts from mands. → Study this topic

Data should be entered promptly after each session — many agencies require same-day or within 24 hours. Timely data entry ensures accurate memory of session events, supports BCBA program decisions, and meets billing documentation requirements. → Study this topic

Spontaneous recovery is the reappearance of an extinguished behavior after a period of absence. It's a normal pattern, not a treatment failure. Continue implementing the plan; the behavior typically decreases again quickly with continued extinction. → Study this topic

Inter-response time (IRT) measures the time between successive occurrences of the same behavior. Different from latency (SD to response). IRT is useful for behaviors where you want to see longer gaps between occurrences (like DRL). → Study this topic

Paired stimulus (also called forced choice) presents 2 items at a time. Every item is paired with every other item across trials. Slower than MSWO but produces detailed preference hierarchy data. → Study this topic

A signed Release of Information (ROI) is required BEFORE sharing client information with other professionals — even for legitimate care coordination. Without ROI, sharing violates HIPAA and BACB ethical requirements. → Study this topic

Billing for time not worked is billing fraud — a federal offense with serious consequences. The RBT must refuse and bill only for actual time. Supervisor pressure to falsify records should be reported through compliance channels. → Study this topic

Latency measures time from the antecedent (SD) to the ONSET of the response. Useful for compliance goals. Distinct from duration (length of the response) and IRT (time between responses). → Study this topic

Non-Contingent Reinforcement (NCR) delivers the maintaining reinforcer on a time-based schedule, regardless of behavior. This reduces the motivating operation for the problem behavior. NCR works because attention is 'free' — the child doesn't need to scream to get it. → Study this topic

Objective language describes only what can be seen or heard by any observer. 'Crossed arms, said no, turned away' — anyone can verify these actions. 'Angry,' 'bad day,' 'upset' are subjective interpretations. → Practice questions

An intraverbal is a verbal response controlled by another verbal stimulus, WITHOUT point-to-point correspondence. The RBT's question ('What do you drink?') has no words in common with the child's response ('juice'). Echoics have point-to-point correspondence. → Study this topic

The behavior consistently produces attention (RBT looks at the child) and stops when attention is delivered. This is a clear attention-maintained function. The intervention would typically involve DRA + extinction (ignore screaming, reinforce appropriate attention-seeking). → Study this topic

Data interpretation is within the BCBA's scope, not the RBT's. The RBT can point out what data shows on the graph but should not draw clinical conclusions. Refer interpretation questions to the BCBA. → Study this topic

The behavior only occurs when access to a specific item is blocked, and stops when access is restored. This is tangible-maintained. Intervention typically involves teaching functional requests and providing structured access to preferred items. → Study this topic

Total task chaining presents the entire chain on every trial, prompting only the steps where the learner struggles. This works best when the learner has partial competence across multiple steps of the chain. → Study this topic

Most-to-least prompting starts with the most intrusive prompt (full physical) and fades to less intrusive prompts across trials. This errorless approach prevents error patterns from developing during acquisition. → Study this topic

Forward chaining teaches the first step to mastery, then adds the second step, and so on. Backward chaining works the opposite way (last step first). Total task presents the entire chain every trial. Shaping reinforces approximations of a single response, not a sequence. → Study this topic

A downward trend during intervention means the behavior is decreasing — often the goal for problem behaviors. Trend describes the overall direction of the data path. Also evaluate level (average) and variability. → Practice questions

RBTs must work within their boundaries of competence. Working with a new population without training is an ethical violation. Request appropriate training and supervision before accepting the case. → Study this topic

Shaping reinforces successive approximations of a target behavior. Each approximation must be closer to the target than the previous one. Chaining teaches multi-step sequences; shaping refines a single response over time. → Practice questions

Required components of a skill acquisition plan include: operational definition of target behavior, teaching procedure, reinforcement schedule, mastery criteria, data collection method, and generalization/maintenance plans. Personal notes about the family are not a formal plan component. → Study this topic

Preference (what someone likes) does not always predict reinforcer effectiveness (what actually increases behavior). Reinforcer effectiveness must be tested by measuring whether the item actually strengthens behavior. This is a critical distinction on the exam. → Practice questions

Multiple relationships (professional + personal) compromise objectivity. Babysitting for a client's family creates a dual relationship that's prohibited by BACB ethics. Even with BCBA approval, this arrangement is typically inappropriate. → Practice questions

Satiation on the backup reinforcer is the most common cause of token economy failure. When candy no longer motivates, tokens lose their conditioned reinforcing value. Solutions include rotating backup reinforcers or conducting a new preference assessment. → Study this topic

Designing behavior interventions is outside the RBT scope of practice. This is the BCBA's responsibility. The RBT should politely refer the parent to the BCBA, not attempt to design plans or consult unauthorized sources. → Study this topic

DRA (Differential Reinforcement of Alternative behavior) reinforces an appropriate alternative (asking for attention) to the problem behavior (hitting). The alternative behavior serves the same function but is socially appropriate. → Study this topic

Free-operant preference assessment provides free access to items and measures engagement duration. Best for learners who can't reliably select from structured arrays. Duration of engagement indicates preference. → Study this topic

Required BIP components include: operational definition of target behavior, hypothesized function, antecedent strategies, consequence strategies (reinforcement + reduction), crisis procedures, and data collection plans. → Practice questions

Responding professionally to feedback is a core BACB requirement. Accept the feedback, ask clarifying questions if needed, and implement recommended changes. Defensiveness or ignoring feedback are ethical concerns. → Practice questions
