Sample Question 1 — Professional Conduct and Scope of Practice

A BCBA working in a school setting observes a teacher using physical punishment to manage a student's disruptive behavior. What is the BCBA's ethical and professional responsibility?

  1. A. Discreetly observe and continue documenting the student's behavior.
  2. B. Immediately report the incident to the school principal and child protective services, documenting the event thoroughly. (Correct answer)
  3. C. Advise the teacher on more appropriate behavior management strategies, emphasizing positive reinforcement.
  4. D. Inform the teacher of the potential legal implications and advise them to cease this practice.

Correct answer: B

Explanation: Option B aligns with the BACB's ethical code regarding reporting suspected abuse or neglect. Physical punishment is illegal and unethical in many contexts. While options C and D might be part of a larger response, immediate reporting is paramount. Option A is a failure to act responsibly.

Sample Question 2 — Professional Conduct and Scope of Practice

A parent requests that a BCBA implement a treatment plan that includes a technique the BCBA believes is ineffective and potentially harmful. How should the BCBA proceed?

  1. A. Implement the parent's requested plan, as the parent has the ultimate say in their child's treatment.
  2. B. Refuse to implement the plan and terminate services.
  3. C. Discuss the potential risks and limitations of the parent's requested technique, and present data-driven alternative interventions. (Correct answer)
  4. D. Compromise and implement a modified version of the parent's plan, incorporating some of the BCBA's suggestions.

Correct answer: C

Explanation: Option C is the most ethical and professional approach. It prioritizes client welfare while respecting parental input. Options A and B are extreme and unprofessional. Option D might work in some cases but fails to fully address the ethical concerns if the core technique remains problematic.

Sample Question 3 — Professional Conduct and Scope of Practice

A BCBA receives a referral for a client who presents with self-injurious behavior (SIB). The BCBA has limited experience with SIB. What is the most ethical course of action?

  1. A. Accept the referral and begin treatment, using online resources to guide the intervention.
  2. B. Accept the referral and utilize an existing treatment protocol without modifications.
  3. C. Accept the referral and collaborate with a more experienced BCBA for consultation and supervision. (Correct answer)
  4. D. Reject the referral due to lack of experience.

Correct answer: C

Explanation: Option C best reflects ethical and competent practice. It prioritizes client safety by seeking expert guidance when necessary. Option A is dangerous due to the lack of expertise; B is insufficient; D is a possible breach of professional responsibility if it limits access to care.

Sample Question 4 — Professional Conduct and Scope of Practice

During a supervision session, a BCBA supervisor observes that their supervisee is consistently violating client confidentiality. What should the supervisor do?

  2. B. Address the issue informally during the next supervision session.
  3. C. Immediately report the supervisee to the BACB.
  4. D. Document the violations, provide corrective feedback, and develop a plan for remediation. (Correct answer)

Options A and B are ineffective; Option C is premature and potentially harmful to the supervisee’s career without first attempting remediation.
