6 Free RBT Behavior Acquisition Practice Questions with Answers

Sample Question 1 — Skill Acquisition

A BCBA has written a discrete trial training (DTT) program to teach Maya, a 4-year-old with autism, to identify colors. The program says: (1) present one color card, (2) give the SD: “What color?”, (3) wait up to 3 seconds for a response, (4) provide reinforcement for correct responses, and (5) record data each trial. During a session, you present the card, say “What color?”, Maya answers correctly, and you immediately move to the next trial without giving any praise or token. What should you do differently to correctly implement the DTT program?

  1. A. Skip reinforcement because Maya already knows the answer
  2. B. Provide the programmed reinforcement immediately after each correct response (Correct answer)
  3. C. Only reinforce Maya at the end of the session, not after each trial
  4. D. Give reinforcement before presenting the SD to motivate Maya

Correct answer: B

Explanation: The RBT Task List requires RBTs to correctly implement skill acquisition plans written by the BCBA, including discrete-trial teaching procedures. In DTT, each trial includes an SD, a response, and a consequence (reinforcement or error correction). Correct answer: B. The program clearly states to provide reinforcement for correct responses. As the RBT, you must follow the written plan and deliver the programmed reinforcer immediately after the correct response to strengthen the skill. Why the others are incorrect: - A: Skipping reinforcement goes against the written program and may reduce correct responding. - C: Only reinforcing at the end of the session does not follow the DTT structure and weakens the connection between the response and reinforcement. - D: Giving reinforcement before the SD is noncontingent and does not follow the BCBA’s plan. Reinforcement should follow the correct response, not come before it.

Sample Question 2 — Skill Acquisition

Your BCBA has created a natural environment teaching (NET) program to increase 6-year-old Leo’s spontaneous mands (requests) for preferred items. The plan says: (1) arrange the environment so favorite toys are visible but out of reach, (2) wait for Leo to show interest, (3) prompt him to request if needed, and (4) immediately give the item and praise when he requests. During a session, Leo reaches toward a toy car on a high shelf and looks at you. According to the NET program, what is the BEST thing for you to do next?

  1. A. Ignore him so he learns to get the toy by himself
  2. B. Immediately hand him the toy car without requiring any response
  3. C. Prompt Leo to request the toy car (for example, by saying, “Say ‘car’” or “What do you want?” as written in the plan) (Correct answer)
  4. D. Tell Leo he can have the toy car only after he finishes all his table work

Correct answer: C

Explanation: NET focuses on teaching skills in natural, everyday situations using the child’s motivation. The RBT Task List includes implementing naturalistic teaching procedures as written by the BCBA. Correct answer: C. Leo is showing interest (reaching and looking at you), which is the cue in the plan to prompt a request if he doesn’t already ask. You should follow the BCBA’s instructions and provide the appropriate prompt so he can practice manding. Why the others are incorrect: - A: Ignoring him misses a teaching opportunity and does not follow the NET plan. - B: Giving the toy with no response does not teach the communication skill the plan targets. - D: Making the toy contingent on finishing table work changes the purpose of the program and does not follow the written NET procedure.

Sample Question 3 — Skill Acquisition

A BCBA has written a chaining program to teach 10-year-old Sam to wash his hands independently. The task analysis lists 10 steps. The plan says you should use backward chaining: you complete the first 9 steps for Sam, then prompt him to do step 10 (drying hands), and reinforce when he completes that last step. During the session, you have Sam do all 10 steps with prompts from you. Are you correctly following the chaining procedure, and what should you do instead?

  1. A. Yes, because having Sam do all steps is always better than doing some steps for him
  2. B. No, you should only have Sam do the last step at first, as written in the backward chaining plan (Correct answer)
  3. C. Yes, because any order of steps is fine as long as he washes his hands
  4. D. No, you should skip any steps that Sam doesn’t like to keep him motivated

Correct answer: B

Explanation: The RBT Task List requires RBTs to correctly implement chaining procedures according to the BCBA’s written plan. In backward chaining, the learner completes the last step independently (with prompts as needed), while the RBT completes the earlier steps. Correct answer: B. The BCBA specified backward chaining, so you should complete steps 1–9 for Sam, then prompt and reinforce step 10. Over time, more steps are transferred to Sam as directed by the BCBA. Why the others are incorrect: - A: Having Sam do all steps is not always better if it does not match the written procedure. Your role is to follow the plan, not change it. - C: The order and method of teaching steps matter in chaining. Any order is not acceptable if it conflicts with the BCBA’s program. - D: Skipping steps changes the task analysis and the program, which is outside the RBT scope.

Sample Question 4 — Skill Acquisition

You are running a skill acquisition program to teach 5-year-old Nina to tact (label) animals using picture cards. The BCBA’s plan says to use a most-to-least prompting hierarchy: (1) start with a full verbal model (e.g., “Say ‘dog’”), (2) fade to a partial verbal prompt, then (3) fade to an independent response as she is successful. During a trial, you show a picture of a dog and Nina says nothing. According to the prompting plan, what should you do?

  1. A. Wait silently for 30 seconds to see if she responds on her own
  2. B. Give the full verbal model prompt: “Say ‘dog’” (Correct answer)
  3. C. Skip the prompt and move to the next card
  4. D. Tell Nina the answer is ‘dog’ and then end the session

Correct answer: B

Explanation: The RBT Task List includes correctly implementing prompting procedures as described in the skill acquisition plan. In a most-to-least prompt hierarchy, you start with the most intrusive prompt and then fade prompts as the learner is successful. Correct answer: B. Since Nina did not respond independently, you should provide the full verbal model prompt, as that is the first step in the most-to-least prompting sequence written by the BCBA. Why the others are incorrect: - A: Waiting a long time without prompting does not follow the prompting plan and may lead to frustration or non-responding. - C: Skipping the prompt and moving on misses the teaching opportunity and does not follow the hierarchy. - D: Simply telling her the answer and ending the session does not provide practice with the prompted response and does not follow the written procedure.

Sample Question 5 — Skill Acquisition

Your BCBA has created a token economy program to increase 7-year-old Alex’s on-task behavior during table work. The plan states: (1) give Alex one token for every 2 minutes of on-task behavior, (2) when he earns 5 tokens, he can trade them for 5 minutes of tablet time, and (3) remind him of the token rules at the start of each session. During a session, Alex earns 3 tokens and then asks to trade them in for tablet time. What should you do to correctly follow the token system?

  1. A. Let him trade 3 tokens for tablet time so he stays motivated
  2. B. Tell him he can trade in 3 tokens for a shorter amount of tablet time
  3. C. Review the rule that he needs 5 tokens to trade, and continue the token earning as written in the plan (Correct answer)
  4. D. Stop using tokens for the rest of the session and just give him tablet time for working

Correct answer: C

Explanation: The RBT Task List includes implementing token economies and reinforcement systems exactly as written by the BCBA. Changing the rules of the token system can make it less effective and inconsistent. Correct answer: C. You should calmly remind Alex of the rule (5 tokens = 5 minutes of tablet time) and continue to award tokens according to the plan. This keeps the system consistent and follows the BCBA’s written program. Why the others are incorrect: - A: Allowing a trade at 3 tokens changes the criteria and does not follow the plan. - B: Adjusting the amount of tablet time is also changing the program, which is outside the RBT scope. - D: Stopping the token system and just giving tablet time ignores the written plan and may reduce the effectiveness of the intervention.

Sample Question 6 — Skill Acquisition

A BCBA has written a discrete trial training (DTT) program to teach Mateo to identify colors. The program says: (1) present one color card, (2) say “What color?”, (3) wait up to 5 seconds for a response, (4) provide reinforcement for correct responses, and (5) record correct or incorrect. During a trial, you show a red card, say “What color?”, and Mateo says “blue.” What should you do NEXT according to typical DTT procedures?

  1. A. Say, “No, that’s wrong,” remove the card, and move on to a different program
  2. B. Ignore the response, keep the card up, and wait silently for Mateo to correct himself
  3. C. Mark the response as incorrect, represent the SD with the same card, and provide the prompted correct response as the program describes (Correct answer)
  4. D. Give partial reinforcement so Mateo doesn’t get discouraged and then move to the next trial

Correct answer: C

Explanation: In discrete trial training, each trial has a clear sequence: SD (instruction), learner response, consequence, and data recording. When the learner responds incorrectly, the RBT follows the error-correction steps written in the program. Option C is correct because it includes (1) marking the response as incorrect (measurement) and (2) immediately re-presenting the SD and prompting the correct response, which is a common error-correction procedure described in many BCBA-written DTT programs. This matches the RBT Task List item of implementing skill acquisition plans, including DTT and prompting. Option A is incorrect because simply saying “that’s wrong” and moving on does not follow typical error-correction procedures and does not help Mateo learn the correct response. Option B is incorrect because just waiting silently does not provide teaching or prompting; it also may increase frustration and does not follow typical DTT structure. Option D is incorrect because giving “partial reinforcement” for an incorrect response would reinforce errors. RBTs should not decide to change reinforcement procedures on their own.
