BCBA Sample Questions

  1. Question 1

    Case Study

    A mid-sized software company, 'Innovate Inc.', hires a BCBA to address issues with project deadlines being consistently missed. The BCBA's initial assessment involves interviews and direct observation, revealing that developers often work on tasks not aligned with project priorities and that communication between project managers and developers is infrequent and lacks clarity. Project managers provide feedback only when a deadline is missed, and there are no clear consequences for early or on-time completion.

    The company has a flat organizational structure, and project managers have limited authority to provide monetary bonuses. The development teams are highly skilled but report feeling 'disconnected' from the project goals. The BCBA needs to propose an intervention package to increase on-time project completion.

    Which intervention package is most appropriate given the assessment findings and organizational constraints?

    Answer and explanation

    Correct answer: C

    This package directly addresses the identified deficits: lack of task clarity, poor communication, and infrequent positive reinforcement. Task clarification (checklists) aligns developer behavior with priorities. Daily meetings improve communication. Public recognition provides a potent, non-monetary reinforcer that fits within the company's constraints and addresses the feeling of being 'disconnected.' This is a comprehensive, antecedent- and consequence-based solution derived from the assessment.

  2. Question 2

    A BCBA is supervising a trainee who is accruing fieldwork hours. The trainee has accrued 100 total hours in a calendar month. According to BACB standards for Supervised Fieldwork, what is the minimum number of supervisor contacts and the minimum number of supervised hours required for that month?

    Answer and explanation

    Correct answer: B

    The BACB standards for Supervised Fieldwork require that 5% of the total fieldwork hours for the supervisory period (one calendar month) be supervised. For 100 hours, this is 5 hours (100 * 0.05). The standards also require a minimum of 4 supervisor-trainee contacts per month for this type of fieldwork.

  3. Question 3

    Case Study

    'GreenLeaf Assisted Living' provides services for elderly residents, some with mild cognitive impairment. The facility director contacts a BCBA to address a high rate of resident falls during nighttime hours (10 PM - 6 AM). Staff report that residents often get out of bed unassisted to use the restroom. The facility uses bed alarms, but staff are often busy with other tasks and respond slowly. The director is concerned about client safety and potential liability.

    The BCBA conducts a descriptive assessment and finds that falls are most common between 2 AM and 4 AM and are almost always associated with attempts to walk to the bathroom. The staff consists of two certified nursing assistants (CNAs) for 30 residents at night, and their primary reinforcement is avoiding reprimands from the nursing supervisor.

    Which intervention plan best incorporates behavior-analytic principles while considering the context of the environment and population?

    Answer and explanation

    Correct answer: B

    This plan is function-based and antecedent-focused. The time-based schedule (an antecedent intervention similar to noncontingent reinforcement) addresses the establishing operation (needing to use the restroom) before the problem behavior (unassisted walking) occurs. It is proactive rather than reactive. The positive reinforcement component for staff shifts the contingencies from negative reinforcement (avoiding reprimands) to positive reinforcement, which is more effective and ethical for performance management.

  4. Question 4

    Case Study

    A BCBA is hired to develop a social skills program for a community center that serves adolescents from diverse cultural and socioeconomic backgrounds. The center's director wants a 'one-size-fits-all' curriculum that can be implemented quickly and efficiently by the center's staff, who have minimal training in behavior analysis.

    An initial indirect assessment, including interviews with teens and their families, reveals a wide range of social goals. Some families prioritize skills related to assertiveness and independent problem-solving, while others emphasize skills related to group harmony, respect for elders, and seeking guidance from authority figures. A direct observation assessment confirms that the specific social deficits vary significantly among the adolescents.

    The BCBA knows that the director's request for a standardized curriculum conflicts with the assessment data and the principle of culturally responsive practice. The center has limited funding, and extensive staff training is not feasible in the short term.

    Which of the following plans best balances ethical obligations, client preferences, scientific evidence, and contextual constraints?

    Answer and explanation

    Correct answer: C

    This option represents the best synthesis of the competing demands. It respects the contextual constraint of limited staff training by focusing on a core set of skills. It honors client preferences and cultural variables by creating optional modules that align with the diverse goals identified. This modular approach is evidence-based and allows for a degree of individualization without requiring a fully unique plan for each adolescent, making it feasible within the center's resource constraints. It directly uses assessment data to inform intervention design, which is a hallmark of effective practice.

  5. Question 5

    A BCBA is supervising a trainee who is accruing fieldwork hours in a concentrated supervised fieldwork arrangement. The trainee works 100 hours in a calendar month. According to BACB standards, what is the minimum number of supervisor contacts and the minimum number of supervised hours required for that month?

    Answer and explanation

    Correct answer: D

    For concentrated supervised fieldwork, the BACB requires a minimum of 6 supervisor contacts per supervisory period (calendar month) and supervision for 10% of the total fieldwork hours. In this case, with 100 total hours, the required supervision is 10% of 100, which is 10 hours. Therefore, the trainee needs a minimum of 6 contacts and 10 supervised hours.

  6. Question 6

    Case Study

    'GreenLeaf Assisted Living' provides services for elderly residents, some with mild to moderate dementia. The facility has seen an increase in nighttime falls among residents who attempt to get out of bed unassisted to use the restroom. The current protocol involves bed alarms that alert the Certified Nursing Assistants (CNAs), but response times are often slow, and falls still occur. The facility director wants a solution that is both effective and respects the dignity of the residents.

    A BCBA is brought in to consult. A descriptive assessment reveals that the falls are most common between 1 AM and 4 AM. Staff interviews indicate that CNAs are often busy with other tasks and view the alarms as a nuisance. The primary function of the residents' behavior (getting out of bed) appears to be access to the restroom.

    The BCBA needs to propose an intervention that is proactive, function-based, and considers the systemic issues within the facility.

    Which of the following interventions is most aligned with behavior-analytic principles and the contextual factors of this case?

    Answer and explanation

    Correct answer: B

    This intervention is the most comprehensive and behavior-analytic. The time-based schedule of assistance is an antecedent intervention (specifically, noncontingent reinforcement or NCR-like procedure) that addresses the function of the behavior (access to restroom) by providing it proactively, thus reducing the motivation for residents to get up unassisted. The reinforcement system for the CNAs addresses the systemic/OBM issue of slow response times and competing contingencies. This dual approach addresses both the client and staff behavior, fits the context, and respects resident dignity.

  7. Question 7

    A BCBA supervisor observes a trainee implementing a DTT procedure incorrectly. To correct the performance, the supervisor explains the correct procedure, demonstrates it, has the trainee practice it, and then provides immediate positive and corrective feedback. This package is best described as:

    Answer and explanation

    Correct answer: B

    Behavioral Skills Training (BST) is an empirically validated training package that consists of four components: instructions, modeling, rehearsal (practice), and feedback. The scenario describes the exact implementation of BST to teach a new skill to the trainee.

  8. Question 8

    A BCBA supervisor observes a trainee implementing a DTT procedure incorrectly. To provide effective, culturally responsive feedback, the supervisor decides to use Behavioral Skills Training (BST). Which component of BST is most critical for ensuring the trainee can perform the skill correctly in the future?

    Answer and explanation

    Correct answer: C

    Behavioral Skills Training (BST) consists of four components: instructions, modeling, rehearsal, and feedback. While all are important, the rehearsal (practice) and feedback components are the most critical for skill acquisition. This active responding allows the supervisor to assess the trainee's performance directly and provide immediate, behavior-specific feedback to shape the correct response, which is a hallmark of effective training.

  9. Question 9

    A BCBA supervisor is establishing a new supervisory relationship with a trainee. The supervisor wants to ensure the relationship is effective and equitable from the start. Which of the following is the most critical initial step in establishing an effective supervisory relationship?

    Answer and explanation

    Correct answer: B

    A formal, written supervision contract is a foundational component of an effective supervisory relationship. It serves to clarify expectations for both the supervisor and supervisee, define roles and responsibilities, establish goals, and provide a framework for feedback and evaluation, thereby preventing misunderstandings and promoting a positive, productive relationship.

  10. Question 10

    A behavior analyst working in an organizational behavior management (OBM) setting is tasked with improving the performance of a sales team. After conducting a Performance Diagnostic Checklist (PDC-HS), the results indicate a deficit in skills and knowledge regarding a new product line. Which of the following interventions would be most functionally matched to this assessment outcome?

    Answer and explanation

    Correct answer: C

    A function-based approach to intervention requires matching the solution to the identified problem. The Performance Diagnostic Checklist (PDC-HS) indicated a deficit in skills and knowledge ('can't do' problem), not a motivation or contingency issue ('won't do' problem). Behavior Skills Training (BST) is an empirically validated method for teaching new skills, making it the most appropriate intervention to address a knowledge and skills deficit.
