Board Certified Behavior Analyst (BCBA) certification examination Study Guide

Apply it

A school records that disruptions occur most often during writing. The analyst describes the pattern and predicts higher disruption during writing, then evaluates a planned manipulation before claiming that task conditions control the behavior.

Apply it

A team explains missed assignments as laziness. The analyst measures assignment length, available assistance and completion across conditions, developing an account that can be evaluated rather than treating the label as a demonstrated cause.

Apply it

An adult reports anxiety before meetings. The analyst respects that report while measuring participation and relevant circumstances, then evaluates a clearly described intervention and whether useful changes persist outside the original training meetings.

Apply it

A dental sound begins eliciting tension after painful visits. Separately, requesting a pause becomes more frequent because the dentist honors requests. The first relation illustrates respondent conditioning; the second illustrates an operant contingency.

Apply it

A supervisor removes an irritating reminder after an employee submits a report. Report submission increases across later opportunities. Removal followed by increased responding supports negative reinforcement, regardless of whether the supervisor calls the arrangement a reward.

Apply it

Consider a chained fixed-ratio 3, fixed-ratio 5 schedule: under a red light, three responses produce a green light; under the green light, five responses produce a token. Both requirements must be completed in order. Keeping one unchanged light throughout the same response requirements would create a tandem arrangement. Separately, making sorting and proofreading available simultaneously, each with its own reinforcement schedule, illustrates concurrent schedules.

Apply it

After extended exercise, water becomes more valuable and water seeking increases. A working dispenser light signals that pressing the button will produce water. Exercise supplies the motivational change; the light signals differential availability.

Apply it

An assessment indicates that desk banging produces breaks. Staff stop giving comments but continue ending work after banging. Attention has changed, yet the maintaining escape contingency remains; escape extinction has not been implemented in this arrangement.

Apply it

A child learns to request help from one instructor, later requests help from a librarian, and also begins using a new help phrase. Requests occurring months later additionally demonstrate maintenance if measured under the specified follow-up conditions.

Apply it

A learner says water while thirsty and receives a drink, then says water while labeling a picture for praise. Identical words participate in different operants because the controlling antecedents and characteristic consequences differ across those occasions.

Apply it

Two activities produce comparable reinforcers. One yields 30 reinforcers and the other 10 during observation. Basic matching predicts approximately three quarters of responding toward the first activity when other influential conditions are comparable across the alternatives.

Apply it

Instead of recording disrespect, a teacher records audible statements directed at another person containing specified insults, beginning with the first word and ending after a defined pause. Disagreements expressed without insults are explicitly excluded from the definition.

Apply it

One session contains 18 requests in 30 minutes and another 12 in 10 minutes. Rates are 0.6 and 1.2 requests per minute, respectively. The shorter session has the higher rate despite its lower total count.

Apply it

A learner starts independent work 95 seconds after an instruction, remains engaged for eight minutes, then pauses between responses. The initiation concern calls for latency measurement; engagement length calls for duration, with separate boundaries defined for each.

Apply it

An observer marks an entire 30-second interval because a shout lasts one second. Reporting that marked interval as 30 seconds of shouting would inflate duration. Event recording would better answer how many discrete shouts occurred during observation.

Apply it

Two observers agree perfectly about completed worksheet pages, but the goal concerns independent reading comprehension. Their agreement supports consistency of page counting, while the mismatch between page totals and comprehension remains a validity problem for the intended decision.

Apply it

A cumulative record becomes steeper after a schedule change, indicating faster response accumulation. The analyst examines local slopes and phase timing rather than interpreting the record's inevitable upward movement as evidence that the intervention improved behavior.

Apply it

Staff correctly deliver praise but provide requested breaks inconsistently. An aggregate checklist score looks high because praise has many steps. Separate measures of break availability and delivery latency reveal the component most relevant to the communication contingency.

Apply it

A communication program begins on the same day classroom staffing changes. Improved requests may reflect either event. Staggered introduction across comparable tiers can help distinguish intervention-related effects from a schoolwide change occurring at a single time.

Apply it

Three classrooms show stable disruption. Intervention starts in the first, which improves while the others remain unchanged. Later starts produce corresponding changes in the second and third, supporting the intervention relation through staggered replication across classrooms.

Apply it

An adult's walking goal increases from a baseline-informed level through several achievable daily targets. The analyst evaluates whether walking repeatedly adjusts to each new criterion instead of assuming that any upward trend demonstrates experimental control.

Apply it

Removing reminder cards while retaining feedback tests a package component. Comparing feedback after every task versus every fifth task varies a parameter. Comparing that feedback package with a distinct self-management intervention addresses a comparative question.

Apply it

An analyst experienced in classroom instruction receives a complex feeding referral. The analyst assesses the required expertise, coordinates appropriate professional evaluation and arranges qualified support rather than independently applying unfamiliar procedures after viewing a single training video.

Apply it

A caregiver signs a general intake form. Before a new assessment involving deliberately arranged contingencies, the analyst explains its purpose and procedures in the caregiver's preferred language, checks understanding and obtains the required authorization for that assessment.

Apply it

A school requests an entire clinical file to coordinate classroom supports. The analyst checks authorization and applicable requirements, clarifies the educational purpose and shares the relevant approved information rather than automatically transmitting unrelated personal and family history.

Apply it

A clinic proposes requesting a website testimonial from a former client. The analyst first considers possible service reentry, then explains the website publication arrangements, confidentiality risks and right to rescind. Any published testimonial must accurately identify the former service relationship and disclose that it was solicited. The clinic does not solicit advertising testimonials from current clients.

Apply it

A family prefers shared mealtimes and uses a language unfamiliar to the analyst. The analyst asks about priorities, arranges appropriate language support and develops communication opportunities within that routine rather than automatically prescribing an individual tabletop format.

Apply it

A supervisor is invited to enter a business partnership with a current supervisee and declines to avoid creating a multiple relationship. If an overlapping role nevertheless arises, the supervisor communicates the risks, takes steps toward resolution and documents outcomes. If resolution must be delayed, the supervisor establishes interim safeguards and a specific plan for ending the overlap.

Apply it

For a relocating client, specify the records-transfer date, receiving analyst's review responsibilities and target handoff date. Obtain required authorization before sharing records. Review transition progress; also provide the discontinuation plan and document its acknowledgment and discharge steps.

Apply it

A BCBA receives a request to provide remote services to a client in another jurisdiction. Before accepting, the analyst determines the applicable practice authorization, service and funding requirements instead of assuming existing certification alone authorizes the proposed work.

Apply it

A file labels classroom exits as attention seeking, but records also describe recent sleep changes and a new schedule. The analyst treats the old label as a hypothesis and plans current observations while clarifying relevant health and contextual information.

Apply it

A student never purchases lunch independently. Assessment shows accurate coin selection in practice but difficulty asking the cashier for clarification. The analyst prioritizes the missing interaction skill and evaluates it in the actual purchasing routine with appropriate supports.

Apply it

A learner consistently chooses music over a puzzle. The analyst then compares task responding when music is delivered contingently with responding in a suitable comparison condition, testing whether the preferred music actually strengthens the response required by the program.

Apply it

A learner repeatedly chooses the nearest object in an array. The analyst checks position effects, accessibility and scanning skills before interpreting the result as a stable preference ranking or using the nearest item as the program's main consequence.

Apply it

Adult attention follows most observed disruptions, but staff also provide attention frequently when disruption is absent. The analyst examines both patterns and treats attention maintenance as a hypothesis rather than concluding that the postepisode count alone establishes function.

Apply it

A qualified team compares a demand condition containing a specified escape contingency with a suitable control. Repeatedly elevated responding in the demand condition supports the tested relation more directly than a report that episodes usually occur during work.

Apply it

An adult with previously stable participation begins avoiding seated work and reports pain. The analyst facilitates appropriate medical evaluation, documents the changed context and coordinates assessment rather than presuming that escape from work fully explains the new pattern.

Apply it

A teenager values using public transportation, while staff propose reducing harmless hand movements. Assessment identifies route checking and asking for assistance as barriers to travel. The team prioritizes those skills through a collaborative discussion with the teenager and relevant supporters.

Apply it

A student asks appropriate questions but does so too frequently for the discussion format. A planned DRL arrangement targets a manageable rate while retaining questions. Teaching and reinforcing a help signal instead would address an alternative response through DRA.

Apply it

An adult receives brief attention every two minutes whether or not calling out occurred. That is fixed-time attention. If attention instead requires two minutes without calling out, the arrangement is an interval-based DRO procedure with a different response requirement.

Apply it

A teacher initially models a greeting immediately after a peer approaches, then gradually delays the model. Greetings occurring before the model are recorded as independent, allowing the team to evaluate whether the peer's approach is acquiring stimulus control.

Apply it

An adult learning a sustained stretch first earns feedback for two seconds, then progressively longer durations based on performance. Reinforcing each closer duration approximation shapes endurance; physically guiding the full movement would instead supply a response prompt.

Apply it

A learner can complete most handwashing steps but needs help beginning and sequencing them. Total-task practice may use those existing skills. If independently contacting the final natural outcome is especially useful, a backward-chaining arrangement offers a different instructional structure.

Apply it

A workplace program awards points for completed safety checks and reliably exchanges them for several valued options. The analyst tracks whether safety checks increase and whether employees can actually access the promised exchanges at the stated opportunities.

Apply it

Touching a red card whenever it appears illustrates a simple discrimination. Selecting red after a red sample and blue after a blue sample requires the correct comparison to depend on the sample, illustrating a conditional discrimination.

Apply it

A supervisor demonstrates an interview skill, then asks the trainee to perform it in a new role-play. Reproducing the modeled skill supports imitation; changing future behavior after observing another trainee's feedback can illustrate a broader observational learning process.

Apply it

Each employee earns a break choice after meeting an individual checklist criterion, illustrating an independent contingency. A shared group outcome requiring every member's criterion illustrates an interdependent arrangement and requires attention to different skill levels and possible peer pressure.

Apply it

After teaching an independent help request during clinic tasks, practice with several adults, tasks and materials. Coordinate with workplace staff so ordinary requests encounter appropriate assistance. Assess stimulus generalization with a relevant person or task not used during teaching, and assess response generalization when an untaught, functionally equivalent request occurs. Measure maintenance at planned later intervals after specialist support decreases, documenting which supports and reinforcement arrangements remain in place.

Apply it

In a hypothetical workplace case, an opportunity occurs when a supervisor gives a task instruction that omits one required detail: the item, quantity or destination. The learner will independently ask a question identifying the missing detail, such as 'How many?', within 10 seconds of the instruction ending and before beginning the task, without an additional verbal, gestural or modeled cue. Mastery is at least 4 of 5 opportunities in each of 3 consecutive sessions, with each of 2 supervisors represented in every session. Record independent correct responses divided by opportunities; prompted or absent responses do not meet the criterion. These numerical values illustrate a case-specific goal rather than a universal standard.

Apply it

Assessment supports escape from difficult tasks as a maintaining consequence for throwing materials. The team teaches an accessible break request and arranges a defined response to it, rather than expecting praise for quiet sitting to serve the same function.

Apply it

A published procedure requires frequent specialist delivery unavailable in a community program. The team considers functionally relevant, evidence-informed alternatives that staff can implement accurately, discusses preferences with the client and measures whether the selected adaptation achieves the intended outcomes.

Apply it

A plan reduces interruptions but coincides with fewer appropriate help requests and increased avoidance of the activity. The analyst measures these changes, revisits the contingency and strengthens accessible communication rather than treating the lower interruption count as sufficient success.

Apply it

Communication remains low, and observations show requests are often missed during busy periods. The team improves signal visibility and staff coverage, then evaluates client outcomes under the improved arrangement before concluding that the communication intervention lacks an effective mechanism.

Apply it

A client reliably requests assistance while help is readily available. When a new schedule makes those requests ineffective, earlier desk hitting returns. The team examines the disrupted alternative reinforcement and revises the transition rather than assuming the original treatment never worked.

Apply it

A trainee writes accurate graphs but struggles to explain findings collaboratively to families. The supervisor uses observed meetings and role-plays to set a measurable communication goal, rather than assigning additional graphing exercises simply because those are easy to score.

Apply it

Two supervisees have different access to live practice because of scheduling. The supervisor arranges comparable opportunities and transparent evaluation criteria, discusses needed accommodations and documents responsibilities so progress reflects professional skill rather than unequal exposure to learning opportunities.

Apply it

After explaining a preference assessment, a supervisor demonstrates it, observes the trainee conduct a role-play and provides specific feedback. Practice continues until the trainee meets the defined criteria, followed by observation during appropriate service delivery.

Apply it

Staff perform a procedure accurately during observation but omit documentation when forms are stored in another building. The supervisor improves form access and workflow, then measures completion rather than automatically assigning the entire staff another introductory training.

Apply it

Rather than saying improve your sessions, a supervisor notes that the trainee delivered three prompts before allowing the specified response interval, models the correct timing and arranges practice with immediate feedback on that observable component.

Apply it

A supervisor introduces rehearsal for assessment interviews. Subsequent observations show more accurate questioning, but trainees report limited practice with interpreters. The supervisor retains effective components and expands representative practice, then monitors whether the added opportunities improve relevant performance.
