Free BCaBA practice exam: 60 explained questions across all nine sections

Record review at the start of a case looks for information that bears on the target behavior: medical history and medication changes, previously identified functions, and how the client responded to past interventions. A favorite color has little bearing on the behavior, its function or the choice of intervention.

• AMedication changes that coincide with behavior change are highly relevant to assessment.
• BPast rates of skill acquisition help predict how the client learns.
• CCorrect: a favorite color has little bearing on the target behavior, its function or intervention planning.
• DPreviously identified functions are central information for the new assessment.

Parsimony refers to selecting the simplest explanation that accounts for the observed phenomena without unnecessary complexity. This is a guiding principle in scientific inquiry and behavior analysis.

• ADeterminism is the assumption that behavior is lawful and caused, not about choosing the simplest explanation.
• BEmpiricism is reliance on objective observation and measurement, not a rule for choosing between explanations.
• CCorrect: parsimony means ruling out simple, logical explanations before considering more complex or abstract ones.
• DPragmatism judges ideas by their practical usefulness, not by how simple the explanation is.

Considering whether the intervention components align with the client's daily routines and environment is most important for context fit because interventions that match existing routines are more likely to be implemented consistently and effectively.

• ACorrect: contextual fit asks whether the plan suits the client's routines, setting, values and resources.
• BPast success with other clients speaks to efficacy, not to fit for this client.
• CLow training demand helps feasibility but is only one aspect of fit.
• DBeing new does not make an approach fit the client's context.

For clients with limited verbal ability, goals should specify the exact form of communication to be used (e.g., picture exchange, sign language) to ensure clear measurement parameters and consistent implementation across all team members.

• AInsisting on vocal speech ignores the client's current repertoire and can block functional communication.
• BGoals beyond the client's level set them up to fail and are not socially valid.
• CWithout the response form, the goal is not measurable and staff will reinforce different responses.
• DCorrect: an observable, measurable goal names the communication form, such as picture exchange or signs, that staff will teach and reinforce.

Momentary time sampling provides an estimate of the percentage of time a behavior occurs by recording whether the behavior is happening at specific moments. This is appropriate for behaviors that occur for extended durations, like off-task behavior, when you want to estimate the proportion of time it occurs.

• AOff-task behavior leaves no lasting product to count afterward.
• BCorrect: momentary time sampling records whether off-task behavior is happening at set moments and yields an estimate of percentage of time.
• CLatency measures time from a cue to a response, not the share of time a behavior lasts.
• DFrequency counting suits discrete behaviors; off-task behavior is ongoing and has no clear start or end.

Adapting the intervention to fit within the family's constraints while maintaining key components reflects a collaborative approach that recognizes the importance of feasibility while still preserving the effectiveness of the intervention.

• AHiring help may be unrealistic; the plan should fit the family's resources.
• BStopping the intervention leaves the problem unaddressed when a feasible version is possible.
• CCorrect: adjusting the plan to fit the family's routine while keeping the essential components improves contextual fit and fidelity.
• DInsisting on a plan the family cannot carry out lowers fidelity and ignores contextual fit.

In radical behaviorism, private events (thoughts, feelings) are considered behaviors that follow the same principles as overt behaviors. They are not causes of behavior but behaviors themselves that require explanation.

• ARadical behaviorism does not treat thoughts as a separate cognitive realm; it treats them as behavior.
• BCorrect: Skinner treated thoughts and feelings as behavior, explained by the same principles as public behavior and not as its causes.
• CPrivate events are themselves behavior to be explained; treating them as initiating causes of overt behavior is mentalism.
• DThat is the methodological behaviorist position; radical behaviorism includes private events in its analysis.

Automatic reinforcement occurs when a behavior produces its own reinforcing consequences without mediation by others. The behavior itself generates sensory stimulation that functions as reinforcement, independent of social consequences.

• AVicarious reinforcement refers to watching another person be reinforced; it is not a type of maintaining consequence for one's own behavior.
• BSocially mediated reinforcement is delivered by another person, which is exactly what the stem excludes.
• CIntermittent describes a schedule (not every response is reinforced), not where the reinforcer comes from.
• DCorrect: automatic reinforcement is produced directly by the behavior itself, such as sensory stimulation, without another person's involvement.

Ensuring supervisees provide services within their defined roles and competencies is the primary ethical responsibility of a supervisor. This protects clients from potential harm and ensures services are delivered appropriately according to the supervisee's training and certification.

• APersonal friendships with supervisees create multiple relationships.
• BCorrect: supervisors are responsible for ensuring that supervisees practice only within their role and demonstrated competence.
• CSupervision must meet BACB requirements; minimizing it is not a goal.
• DCaseload maximization is not an ethical responsibility and can harm service quality.

The dependent variable is the target behavior being measured to determine if it changes as a result of the independent variable (intervention). It is the outcome measure of interest.

• AObservation periods are part of the measurement procedure, not a variable.
• BThis is the independent variable: the intervention the experimenter manipulates.
• CConditions held constant are controlled variables, not the dependent variable.
• DCorrect: the dependent variable is the target behavior that is measured to see whether it changes with the intervention.

Active listening and validating the RBT's experience demonstrates empathy while providing guidance that helps the RBT develop problem-solving skills. This approach establishes a supportive supervisory relationship while maintaining a focus on effective service delivery.

• AReassigning immediately avoids the problem and loses a chance to build the RBT's skills.
• BTime off may help in some cases, but it does not address the clinical problem.
• CDismissing the concern harms the supervisory relationship.
• DCorrect: active listening, validation and joint problem-solving strengthen the relationship and build the RBT's skills.

Least-to-most prompting involves starting with the least intrusive prompt (or no prompt) and progressively adding more intrusive prompts as needed. In this case, the analyst starts with no prompt, then provides a gestural prompt, and finally a physical prompt if necessary.

• ACorrect: starting with no prompt and adding more intrusive prompts only as needed is least-to-most prompting.
• BMost-to-least starts with the most intrusive prompt and fades it.
• CGraduated guidance adjusts physical guidance moment to moment; it does not step through a hierarchy.
• DTime delay fades by delaying a controlling prompt; here the prompts escalate from least to most.

This procedure is teaching a tact, which is a verbal operant controlled by a nonverbal stimulus (the ball) and maintained by generalized conditioned reinforcement (praise). The child is learning to label or name objects in the environment.

• ACorrect: naming an object in view is a tact, controlled by the nonverbal stimulus and maintained by generalized reinforcement such as praise.
• BAlthough a question is present, the response is controlled by the ball; an intraverbal has no nonverbal stimulus.
• CTextual behavior is reading written words.
• DA mand is controlled by a motivating operation and reinforced by the specific item.

A stimulus delta (S-delta) signals the unavailability of reinforcement for a particular behavior, while a discriminative stimulus (SD) signals the availability of reinforcement for that behavior. In the presence of an S-delta, a particular response is less likely to occur because reinforcement is unlikely.

• AEliciting respondent behavior describes a conditioned stimulus, not an S-delta.
• BCorrect: an S-delta signals that the response will not be reinforced, while an SD signals that it will.
• CThis describes an SD; an S-delta signals that reinforcement is not available.
• DChanging the value of a reinforcer is the function of a motivating operation, not an S-delta.

Permanent product recording involves measuring the physical results or products of behavior. Completed homework assignments are tangible products left behind by the behavior of completing homework.

• ACounting hand raises during the lesson is direct observation of the behavior as it occurs.
• BCorrect: completed homework is a permanent product left after the behavior, so counting it measures behavior through its outcome.
• CTiming in-seat behavior is direct, continuous duration recording of the behavior itself.
• DChecking eye contact at set moments is direct observation (momentary time sampling), not a product.

Self-management procedures involve teaching individuals to monitor, record, and manage their own behavior. This example includes self-monitoring, goal-setting, and self-reinforcement, which are components of self-management.

• AA token economy uses tokens exchanged for backup reinforcers, delivered by someone else.
• BShaping reinforces successive approximations; here the student manages their own behavior.
• CCorrect: self-monitoring, goal setting and self-delivered reinforcement are components of self-management.
• DA contingency contract is a written agreement between parties, not self-administered consequences.

The four core principles are: benefit others; treat others with compassion, dignity, and respect; behave with integrity; and ensure their competence. Rules on gifts appear as a specific standard, not as a core principle, and the Code permits gifts of very small value.

• AFunder preferences do not override client welfare and are not one of the core principles.
• BCorrect: 'ensure their competence' is one of the four core principles, alongside benefit others, treat others with compassion, dignity and respect, and behave with integrity.
• CThe Code permits gifts of very small value; gift rules are a specific standard, not a core principle.
• DCaseload size is a business goal; the core principles concern benefit, dignity, integrity and competence.

Before implementing a new assessment procedure, the BCaBA should review the relevant research literature and discuss it with their supervising BCBA to ensure it is evidence-based and appropriate for use.

• ATrying it on a client first exposes the client to an unvetted procedure.
• BColleagues' anecdotes do not substitute for the evidence base.
• CCorrect: check the evidence base and consult the supervising BCBA before using a new procedure with clients.
• DWho presented a procedure says nothing about its evidence or fit for the client.

A latency-based functional analysis would be most appropriate for severe self-injury because it measures the time until the first instance of the behavior in each condition and ends the condition after the first occurrence, minimizing the total number of self-injury instances while still providing functional information.

• ACorrect: a latency-based FA ends each session at the first response, which keeps the number of self-injurious responses low.
• BHigh-intensity reinforcement does not reduce risk and may distort the analysis.
• CLonger sessions would allow more self-injury, increasing risk.
• DPunishment components have no place in an FA; they would distort the function being tested.

Magnitude refers to the physical force or intensity of a behavior. When measuring the pressure or force used during aggressive behaviors, the analyst is measuring the magnitude dimension of the behavior.

• ALatency is the time from a stimulus to the start of a response, not its force.
• BFrequency (or rate) is how often the behavior occurs, not how hard.
• CDuration is how long each instance lasts.
• DCorrect: force or intensity of a response is its magnitude.

A motivating operation temporarily alters (a) the value of a stimulus as a reinforcer and (b) the frequency of behaviors that have historically produced that reinforcer. Being thirsty increases the value of water as a reinforcer and the frequency of behavior (requesting 'water') that has historically produced water.

• AConditioned reinforcement concerns a stimulus that acquired value through pairing; it does not explain a momentary shift between requests.
• BAn SD signals that reinforcement is available; here both requests are available, and only the value of water changed.
• CCorrect: thirst is a motivating operation (an unconditioned establishing operation) that raises the value of water and evokes the behavior that has produced it.
• DResponse generalization is an untrained response variation; asking for water is a trained response whose frequency changed.

History effects occur when external events that happen during the study (unrelated to the intervention) influence the dependent variable, threatening the internal validity of the experiment by offering an alternative explanation for behavior change.

• ACorrect: history is any outside event during the study, such as a new medication or a family change, that could explain the change.
• BTesting effects come from repeated exposure to the measurement itself.
• CInstrumentation threats come from changes in the measurement system or observers.
• DMaturation is change caused by growth or development over time, not a discrete outside event.

A multiple baseline design doesn't require withdrawing an effective intervention, making it ethically appropriate for behaviors that should not return to baseline levels (e.g., severe self-injury) or interventions that produce irreversible learning.

• ACorrect: a multiple baseline shows control through staggered introduction, so an effective treatment never has to be removed.
• BMultiple baselines often take longer, because later baselines must run until the intervention reaches them.
• CExternal validity comes from replication, not from the design choice; both designs mainly address internal validity.
• DMore data points is not the defining advantage and is not guaranteed.

Behavior has several dimensions. Here the number of tantrums dropped from 10 to 3 per day while each remaining tantrum lasted longer, so the plan is working on frequency but not on duration. Review the data and refine the procedures to target duration as well.

• AFrequency fell substantially, so the intervention is not failing.
• BIgnoring the increase in duration misses a meaningful dimension of the behavior.
• CSpontaneous recovery is the reappearance of a behavior after extinction; here the behavior never stopped.
• DCorrect: frequency dropped but duration rose, so the plan is working in part and should be refined to target duration.

Teaching a simple, efficient communication response for requesting breaks directly addresses the escape function of aggression by providing an appropriate alternative that requires less effort than aggression but serves the same function.

• AForcing completion regardless of behavior does not teach a replacement and may escalate aggression.
• BPlanned ignoring withholds attention, which does not match an escape function.
• CRestraint is an emergency measure, not a planned treatment component for escape-maintained behavior.
• DCorrect: functional communication training gives the client an easy, appropriate way to obtain a break, matching the escape function.

The return to intervention phase in an ABAB design verifies that the intervention is responsible for behavior change by demonstrating that the behavior improves again when the intervention is reintroduced after a return to baseline conditions.

• AGeneralization would be tested in new settings or with new stimuli, not by reintroducing the intervention.
• BComparing participants is the logic of a multiple baseline across participants, not of the second B phase.
• CCorrect: reintroducing the intervention replicates the effect, so the analyst verifies that the intervention, not chance, changed the behavior.
• DMaintenance is assessed after the intervention is removed or faded, not by reinstating it.

Providing specific, behavior-based feedback immediately after observing performance maximizes the effectiveness of feedback by creating a clear connection between the behavior and the consequence (feedback). This approach applies fundamental learning principles to supervision.

• ACorrect: specific, behavior-based feedback delivered right after observation is most effective for building skills.
• BGeneral feedback does not tell the supervisee what to change.
• CSelf-reflection can help, but on its own it is weaker than direct, specific feedback.
• DDelayed monthly feedback is too far removed from the performance.

The BCaBA should seek supervision and prepare thoroughly under guidance before conducting the workshop, acknowledging limitations while taking steps to ensure competent service delivery.

• AAccepting work outside one's competence is not fixed by narrowing the topic without guidance.
• BCorrect: BCaBAs practice within their competence and under BCBA supervision, so preparing under an experienced BCBA's guidance is the right course.
• CDeclining is not required; the gap can be addressed through supervision and preparation.
• DSelf-study without supervision does not establish competence, and BCaBAs work under supervision.

Behavior analysis as a natural science aims to describe, predict, and control behavior through systematic observation and experimentation, adhering to scientific principles of investigation.

• ABehavior analysis studies environment-behavior relations; genetics is a separate field, though phylogeny is acknowledged as a source of behavior.
• BCognitive theories posit inner processes; behavior analysis explains behavior through its relation to the environment instead.
• CCorrect: as a natural science, behavior analysis seeks three levels of understanding: description, prediction and control of behavior.
• DThe unconscious mind is a psychodynamic construct, a hypothetical cause that behavior analysis rejects as mentalistic.

A normative criterion compares an individual's performance to that of a relevant peer group. In this example, the criterion is based on how typically developing peers perform on the same skill, establishing a norm-referenced standard for mastery.

• AAllowing a number of reminders sets a prompting criterion, not a comparison with peers.
• BCorrect: a normative criterion compares performance with that of typical peers, here grade-level oral reading rate.
• CTen consecutive independent days is a durability (maintenance) criterion, not a peer norm.
• DAn accuracy percentage across sessions is a standard performance criterion, not a normative one.

Reliability is necessary for validity, but not sufficient to ensure it. A measurement can be reliable (consistent) without being valid (accurately measuring what it claims to measure), but a measurement cannot be valid if it is not reliable.

• AThey are related: a measure that is inconsistent cannot be trusted to reflect the true value.
• BA measure can be consistently wrong, for example a miscalibrated stopwatch, so reliability does not guarantee validity.
• CCorrect: reliable (consistent) measurement is needed for validity, but a consistent measure can still measure the wrong thing.
• DValidity depends on reliability, not the reverse; a valid measure must already be reliable.

An interdependent group contingency provides a consequence to the entire group based on the collective performance of all group members. In this case, the entire class earns extra recess time based on the collective behavior of lining up quickly.

• AAn independent contingency applies the same criterion to each student individually.
• BA dependent contingency rewards the group based on one or a few students' performance.
• CThe reward depends on lining up quickly, so it is contingent.
• DCorrect: the whole class earns the reward only if the group as a whole meets the criterion, which is an interdependent group contingency.

Providing non-contingent teacher attention on a fixed-time schedule directly addresses the attention function by ensuring the student receives regular attention without needing to engage in disruptive behavior, thereby reducing the motivation for the problem behavior.

• AEscape from work does not match an attention function and would reinforce leaving work.
• BRemoving the student may give attention and escape, and it does not address the attention function.
• CCorrect: fixed-time teacher attention matches the attention function and reduces the motivation to disrupt for attention.
• DTangibles do not address the attention function that maintains the behavior.

Consulting cultural experts and your supervisor ensures that cultural practices are integrated respectfully and appropriately.

• AIntegrating a practice without understanding it risks harm and poor contextual fit.
• BAvoiding all cultural practices ignores the family's values and the need for culturally responsive care.
• CIndependent research alone skips the supervisor, who oversees the BCaBA's work.
• DCorrect: consult people who know the practice and your supervising BCBA before changing treatment.

A token economy is a system where conditioned reinforcers (tokens) are delivered contingent on target behaviors and later exchanged for backup reinforcers. This example shows tokens being delivered for on-task behavior and exchanged for computer time.

• ACorrect: tokens earned for behavior and exchanged for backup reinforcers form a token economy.
• BResponse cost removes tokens after problem behavior; nothing is removed here.
• CDifferential reinforcement is broader; the defining feature here is the token-and-exchange system.
• DFixed-interval schedules reinforce the first response after an interval; the defining feature here is the exchange of tokens.

Operationally defining expected behaviors provides clear, measurable criteria for performance evaluation. This prevents misunderstandings and ensures that expectations are objective and observable, which is essential for effective supervision.

• ACorrect: clear expectations require operational definitions of what acceptable performance looks like.
• BHierarchy does not clarify what the supervisee should do.
• CA form can help, but without defined behaviors it does not make expectations clear.
• DA meeting schedule organizes supervision but does not define expected performance.

Extinction can produce an extinction burst and emotional responses, including aggression that was not part of the original behavior. Spontaneous recovery is the return of the extinguished behavior itself after a pause. The plan should anticipate this and include safety steps and reinforcement of an alternative response.

• ACorrect: aggression that appears when a behavior is placed on extinction is extinction-induced aggression, a known unwanted effect.
• BResponse generalization is a new variation of a reinforced response, not a reaction to extinction.
• CBehavioral contrast is a change in behavior in one setting when the contingencies change in another.
• DSpontaneous recovery is the return of the extinguished behavior itself (whining), not a new behavior.

Latency recording measures the time between a stimulus (in this case, the child's name being called) and the beginning of a response. This is ideal for measuring response speed or delay in reacting to specific stimuli.

• AFrequency counts how often responding occurs, not how quickly it starts after the name is called.
• BDuration measures how long a response lasts once it has started.
• CInterval recording estimates occurrence within time intervals and loses the timing of each response.
• DCorrect: latency is the time between a stimulus (name called) and the start of the response.

Negative reinforcement occurs when a behavior increases because it results in the removal or avoidance of an aversive stimulus. In this case, completing homework increases because it helps avoid the aversive consequence of a failing grade.

• APositive punishment would add a stimulus after the behavior and decrease it; homework completion is increasing.
• BPositive reinforcement adds a stimulus; here the behavior works by avoiding an aversive outcome.
• CCorrect: doing homework avoids the failing grade, so the behavior is maintained by negative reinforcement (avoidance).
• DNegative punishment removes a stimulus and decreases behavior; homework completion is being maintained, not reduced.

Maintaining separate personal and professional social media accounts helps establish clear boundaries between personal and professional relationships.

• ASocial activities with clients create a multiple relationship and blur boundaries.
• BGifts of very small value are allowed under the Code, but accepting gifts is not a way of keeping boundaries.
• CCorrect: keeping personal and professional social media separate protects clients' privacy and professional boundaries.
• DSharing personal contact details invites personal contact; emergencies go through the agency's procedures.

Total task chaining involves teaching all steps of the chain in each session, with the learner attempting the entire task sequence. The instructor provides prompts as needed for steps the learner cannot yet complete independently, then gradually fades these prompts over successive teaching trials.

• ACorrect: in total task chaining the learner attempts every step in each session, with prompts where needed.
• BThis describes forward chaining.
• CTeaching steps in random order is not a chaining method.
• DThis describes backward chaining.

A scatterplot showing clusters of behavioral occurrences at specific times of day (e.g., consistently more occurrences between 10-11 AM) would suggest a temporal relationship between the behavior and that time period, which might indicate environmental factors specific to that time influencing the behavior.

• AA random pattern suggests no relation between behavior and time of day.
• BAn even spread shows that the time of day does not matter.
• CA gradual increase shows a trend across the day, not a link to a specific time.
• DCorrect: a scatterplot that shows clusters at certain times points to conditions present at those times that may be related to the behavior.

Identifying complementary goals where both professionals can reinforce the same skills from their respective disciplines creates a cohesive intervention that maximizes learning opportunities across therapeutic contexts.

• ACorrect: coordinating on shared goals that both professionals reinforce supports consistent, collaborative care.
• BAsking another professional to use only ABA procedures disregards their expertise and scope.
• CSeparate goals miss opportunities to strengthen the same skills across settings.
• DMonthly notes alone are too limited for effective collaboration.

Negative punishment involves the removal of a stimulus (access to the preferred activity) following a behavior (aggression), resulting in a decrease in the future probability of that behavior.

• APositive reinforcement adds a stimulus and increases behavior; here behavior decreased.
• BNegative reinforcement removes an aversive stimulus and increases behavior; here behavior decreased.
• CCorrect: removing access to a preferred activity (time-out from positive reinforcement) contingent on aggression decreased it, which is negative punishment.
• DPositive punishment adds a stimulus after the behavior; time-out removes access to reinforcers instead.

A behavioral cusp refers to a behavior change that has significant implications beyond the change itself by providing access to new environments, reinforcers, or learning opportunities. Measuring cusps focuses on behaviors that, once acquired, open the door to further development.

• AEarly gains are a treatment effect, not a cusp.
• BA performance ceiling is not a cusp.
• CCorrect: a behavioral cusp gives the learner access to new reinforcers, contingencies and environments, as walking or reading does.
• DClinical significance is a separate question about the size of change.

An intraverbal is a verbal operant evoked by a verbal stimulus with which it has no point-to-point correspondence. Examples include answering questions or completing phrases where the response doesn't match the form of the stimulus.

• ATextual behavior is reading: it has point-to-point correspondence with a written stimulus but no formal similarity to it.
• BAn echoic repeats the speaker's words, so it has point-to-point correspondence and formal similarity.
• CA tact is evoked by a nonverbal stimulus in the environment, not by someone else's verbal behavior.
• DCorrect: an intraverbal is evoked by a verbal stimulus without point-to-point correspondence, such as answering 'What do cows say?' with 'moo'.

Changing data so that it fits expected outcomes is falsification, which the Ethics Code forbids. Refuse to alter the record and bring the request to your supervisor, so it can be addressed as professional misconduct if needed.

• ADelaying leaves the falsification request unaddressed; data integrity requires a clear refusal.
• BCorrect: altering data to fit expectations is falsification; refuse and raise the request with your supervisor.
• CEven minor edits to fit expectations falsify the record.
• DDiscussing 'alternative methods' with the colleague still entertains changing the data rather than refusing.

Taught A=B and B=C, the learner can show untrained relations: symmetry (B=A), transitivity (A=C) and reflexivity (A=A). C=A needs both reversal and linking across B, so it is the combined test for stimulus equivalence. Response generalization concerns response forms, not stimulus relations.

• ACorrect: when C=A emerges after A=B and B=C were taught, it combines symmetry and transitivity, the test for equivalence.
• BResponse generalization is an untrained variation of a reinforced response form; it is not a derived stimulus-stimulus relation.
• CReflexivity is matching a stimulus to itself (A=A).
• DSymmetry is reversing one trained relation, such as B=A after A=B is taught.

In this scenario, the behavior analyst is using differential reinforcement of alternative behavior (DRA) by reinforcing hand-raising (the alternative behavior) while implicitly placing calling out (the problem behavior) on extinction. DRA involves reinforcing a behavior that serves as an alternative to the problem behavior.

• ANCR delivers reinforcement on time, regardless of behavior; here it is contingent on hand-raising.
• BCorrect: reinforcing hand-raising as a replacement for calling out is DRA.
• CDRL reinforces the problem behavior when it occurs at a lower rate; hand-raising is a different behavior.
• DDRO reinforces the absence of the problem behavior for an interval, not a specific replacement response.

Basing supervision frequency and focus on demonstrated skill levels and specific competency needs applies the principle of individualization. This approach ensures supervision resources are allocated according to objective assessment of supervisee needs.

• AEqual supervision by credential ignores individual skill differences.
• BSupervisees may miss their own skill gaps; the supervisor should assess them.
• CTime in position does not demonstrate competence.
• DCorrect: a competency-based approach sets supervision goals and intensity based on assessed skills.

In whole interval recording, the behavior must occur throughout the entire interval to be scored as an occurrence. If the behavior stops at any point during the interval (as in this case, where it only occurred for 45 seconds of the 60-second interval), the interval is scored as a non-occurrence.

• ACorrect: whole interval recording scores an interval only if the behavior lasts the entire interval, so 45 of 60 seconds is a non-occurrence.
• BThe rule is fixed in advance, so the interval can be scored with the information given.
• CScoring any occurrence would be partial interval recording, not whole interval recording.
• DInterval methods score each interval as yes or no; there is no partial score.

Evaluating the impact of the behavior on learning, social relationships, and daily functioning provides a comprehensive assessment of whether the behavior significantly interferes with the individual's quality of life, indicating a need for behavior-analytic services.

• AThe person's preference matters, but it does not by itself establish whether services are warranted.
• BCorrect: services are warranted when a behavior meaningfully affects learning, relationships, safety or daily functioning.
• CAnnoyance to caregivers is not a sufficient reason for intervention.
• DPeer comparison can inform goals, but difference from peers alone does not show the behavior is a problem.

When implementation consistency affects outcomes, the first step should be to assess treatment fidelity across staff members to identify specific areas where implementation differs, which can inform targeted training.

• ACorrect: check treatment fidelity across staff first to identify exactly where implementation differs, then target training.
• BSimplifying the plan may be premature before you know what is going wrong.
• CA new plan is not warranted when the current one works with some staff.
• DLimiting staff avoids the problem rather than fixing implementation.

Assessing current state of satiation is most important when conducting preference assessments with edible items because satiation can temporarily alter preference hierarchies, making items that would typically be highly preferred appear less preferred if the client is already satiated on that item.

• AColor is irrelevant to preference for edible items.
• BCorrect: satiation (a motivating operation) can temporarily lower an item's value, so check it before and during the assessment.
• CRestricting sessions to mealtimes would confound preference with hunger.
• DHealthy choices can be considered, but limiting the array is not the most important factor for valid results.

The 'analytic' dimension requires demonstrating a functional relationship between the intervention and behavior change, typically through experimental designs that control for confounding variables and establish cause-effect relationships.

• ATechnological means procedures are described clearly enough for others to replicate them.
• BCorrect: an analytic study demonstrates experimental control, showing that the intervention, not other variables, produced the change.
• CConceptually systematic means procedures are tied to and described in terms of basic behavioral principles.
• DBehavioral means the target is observable, measurable behavior of the person who needs to change.

The behavior analyst is conducting descriptive functional assessment by collecting ABC (Antecedent-Behavior-Consequence) data in the natural environment. This involves directly observing and recording the antecedents, behaviors, and consequences as they naturally occur to identify patterns related to the target behavior.

• AAn experimental functional analysis manipulates consequences in test conditions; ABC data only record natural events.
• BCorrect: ABC recording in the natural setting is descriptive assessment, a direct but non-experimental method.
• CPreference assessment identifies potential reinforcers, not the function of the behavior.
• DStructural analysis manipulates antecedents to test their effect; ABC recording does not manipulate anything.

The BCaBA should present only de-identified information when discussing cases with individuals not directly involved in the client's care to maintain confidentiality while still allowing for professional education.

• ADeclining entirely is unnecessary; the data can be shared in de-identified form.
• BA guardian's presence is not the safeguard; confidentiality is protected by removing identifying information or obtaining consent.
• CProfessional colleagues outside the case have no need to know identifying details.
• DCorrect: share only de-identified data with people not involved in the client's care, unless consent covers more.

Educating oneself about cultural differences and adapting expectations demonstrates cultural responsiveness while maintaining effective supervision. This approach recognizes and respects cultural diversity while ensuring supervision remains effective.

• AInterpreting a cultural norm as dishonesty is a biased assumption.
• BRecording a cultural norm as a deficit is not culturally responsive.
• CCorrect: learning about the norm and adjusting expectations shows cultural humility and supports an equitable supervisory relationship.
• DRequiring eye contact imposes one culture's norm without a performance reason.

Contriving motivating operations involves creating conditions that increase the value of specific reinforcers to evoke the target behavior. For teaching requesting (manding), the analyst should arrange the environment to establish motivation for specific items that can only be accessed through the use of picture cards.

• AIntraverbals are not the starting point; requesting (mands) is the target here.
• BCorrect: briefly restricting free access to preferred items creates a motivating operation that evokes the request to be taught.
• CA token economy is not the next step for teaching the first requests.
• DTacting is a different operant; the goal is manding under motivation.
