6 Free BCBA Discrete Trial Teaching Practice Questions with Answers

Sample Question 1 — Discrete Trial Teaching

During a discrete trial teaching (DTT) session with a 4-year-old client with autism, the client consistently fails to respond to the instruction "Touch red." The therapist has attempted several prompts but the client remains unresponsive. What is the BEST course of action?

  1. A. Continue presenting the same instruction with increased prompting until the client responds correctly.
  2. B. Immediately switch to a different task or activity to avoid frustration.
  3. C. Conduct a brief error analysis to determine the reason for the non-response (e.g., lack of understanding, difficulty with discrimination, etc.) and adjust the instruction or materials accordingly. (Correct answer)
  4. D. Increase the intensity of prompts until the client responds, regardless of the client's level of frustration.

Correct answer: C

Explanation: Option C is best because it involves a systematic approach to problem-solving. Before escalating prompts or changing tasks, it's crucial to analyze the reason for the non-response. This might involve simplifying the instruction, using different materials, or ensuring the client understands the target behavior. Options A and D risk increasing frustration and potential negative behavior without addressing the root cause. Option B avoids addressing the skill deficit.

Sample Question 2 — Discrete Trial Teaching

A BCBA is supervising a new RBT who is conducting DTT sessions. The RBT consistently uses physical prompts excessively, even when the client shows signs of understanding. What is the MOST appropriate supervisory action?

  1. A. Ignore the issue, assuming the RBT will learn through experience.
  2. B. Provide feedback to the RBT, emphasizing the importance of fading prompts and using least-to-most prompting. (Correct answer)
  3. C. Immediately terminate the RBT's employment.
  4. D. Reprimand the RBT publicly for their actions.

Correct answer: B

Explanation: Option B aligns with ethical and supervisory best practices. Providing constructive feedback and guidance is essential for improving RBT performance. Options A is neglectful, C is excessive, and D is inappropriate and unprofessional.

Sample Question 3 — Discrete Trial Teaching

A client consistently engages in hand flapping during DTT sessions. This behavior disrupts learning. Functional assessment suggests the hand flapping is maintained by attention. What intervention is MOST appropriate?

  1. A. Punish the hand flapping by removing preferred items.
  2. B. Ignore the hand flapping entirely.
  3. C. Provide attention only when the client engages in appropriate behaviors. (Correct answer)
  4. D. Continuously redirect the client to the task at hand.

Correct answer: C

Explanation: Option C uses differential reinforcement of other behavior (DRO). By providing attention only for appropriate behaviors, the attention reinforcement for hand flapping is removed. Options A uses punishment, which is generally avoided unless it's a necessary last resort, and can cause unintended negative side-effects. Option B could potentially reinforce the behavior by providing extinction-induced burst. Option D is less effective than using differential reinforcement.

Sample Question 4 — Discrete Trial Teaching

You are working with a client who is mastering the skill of identifying shapes. You notice the client is consistently responding correctly only when a specific verbal prompt is used. What is the best strategy to promote generalization and reduce prompt dependency?

  1. A. Continue using the same prompt consistently to ensure mastery.
  2. B. Immediately switch to a different task that does not involve shape identification.
  3. C. Systematically fade the verbal prompt and use other prompts like gestural prompts or visual cues, then fade those as well. (Correct answer)
  4. D. Increase the reinforcement for correct responses to increase the likelihood of independent responding.

Correct answer: C

Explanation: Option C addresses the prompt dependency by gradually removing the verbal prompt, ensuring the client learns to respond independently. Option A maintains the dependency, B avoids the issue, and D, while helpful, does not directly address prompt dependency.

Sample Question 5 — Discrete Trial Teaching

During DTT, a client successfully completes 5 trials of identifying colors. The therapist then introduces a new skill: shape identification. What is the MOST appropriate procedure?

  1. A. Continue with color identification until the client masters it completely before introducing shapes.
  2. B. Introduce shape identification immediately after the color trials and alternate between the two skills throughout the session. (Correct answer)
  3. C. Introduce shape identification only if the client answers every color question perfectly.
  4. D. Only teach shape identification if the client displays a high level of engagement in the previous task

Correct answer: B

Explanation: Option B utilizes the principles of task variation to maintain engagement and prevent satiation. Alternating tasks maintains motivation and allows for a more varied and interesting learning session for the client. Options A and C are inflexible and might not be the best approach for maintaining client engagement and teaching multiple skills. Option D uses an unreliable criteria for introducing the next skill

Sample Question 6 — Discrete Trial Teaching

An RBT is using DTT to teach a client to label pictures. The client is showing signs of frustration and avoidance. What should the BCBA do?

  1. A. Tell the RBT to continue until the client completes the task.
  2. B. Immediately increase the reinforcement schedule.
  3. C. Consult with the RBT to review the session and analyze the client's behavior, potentially adjusting the task difficulty or teaching methods. (Correct answer)
  4. D. Ignore the situation; the client will get used to it.

Correct answer: C

Explanation: Option C prioritizes the client's well-being and effective teaching by actively collaborating with the RBT to address the issue. Options A and D disregard the client's discomfort, while B may not be the effective approach if the problem is related to task difficulty or teaching method.
