6 Free RBT Behavior Assessment Practice Questions with Answers

Sample Question 1 — Assessment

A BCBA asks you to help with a preference assessment for Maya, a 6-year-old with autism who rarely approaches toys on her own. The BCBA sets up several toys on the table and tells you exactly how to present two items at a time and record which one Maya chooses. What is the MOST appropriate way for you, as the RBT, to assist with this assessment?

  1. A. Follow the BCBA’s written steps for the preference assessment and record each item Maya chooses. (Correct answer)
  2. B. Change the assessment to only one toy at a time if Maya seems distracted, without checking with the BCBA.
  3. C. Decide which toys should be used in the assessment based on what you think she will like most.
  4. D. Skip recording data and just tell the BCBA which toys you noticed Maya liked.

Correct answer: A

Explanation: The RBT Task List (Assessment) states that RBTs assist with preference assessments by following the BCBA’s procedures and collecting accurate data. - A is correct because it describes the RBT correctly implementing the BCBA’s plan and objectively recording choices. - B is incorrect because changing the assessment procedure without BCBA approval is outside the RBT’s role. - C is incorrect because selecting assessment methods or items without BCBA direction is a clinical decision, which is the BCBA’s job. - D is incorrect because preference assessments require objective data, not just memory or impressions.

Sample Question 2 — Assessment

Your BCBA asks you to help with a free-operant preference assessment for Leo, a 9-year-old with developmental delays. The BCBA places many toys and activities around the room and tells you to observe and record what Leo plays with and for how long. During the assessment, what should you focus on doing?

  1. A. Prompt Leo to try each toy so he doesn’t miss anything.
  2. B. Follow Leo around and record which items he chooses and how long he engages with each one. (Correct answer)
  3. C. Remove any toys Leo doesn’t touch after 1 minute so he has fewer choices.
  4. D. Ask Leo which toy is his favorite and only record that one.

Correct answer: B

Explanation: In a free-operant preference assessment, the RBT observes the client freely interacting with items and records engagement. This fits the RBT Task List item of assisting with preference assessments by collecting data. - B is correct because it describes objective observation and timing of Leo’s engagement with items, as directed by the BCBA. - A is incorrect because prompting Leo to try each toy changes the assessment procedure and may affect results. - C is incorrect because removing toys without BCBA direction changes the assessment design. - D is incorrect because relying only on verbal report and only one item does not follow typical free-operant procedures and does not provide full data.

Sample Question 3 — Assessment

You are helping your BCBA with a preference assessment for Sara, a 4-year-old with autism who does not speak. The BCBA tells you to present one item at a time and record whether Sara approaches, touches, or plays with the item within 5 seconds. When you present a toy car, Sara looks at it, reaches for it, and starts rolling it on the table. What should you record for this trial?

  1. A. Record that Sara rejected the item because she didn’t say she wanted it.
  2. B. Record that Sara approached/selected the item because she reached for and played with it. (Correct answer)
  3. C. Record nothing because she did not play with it for at least 1 minute.
  4. D. Record that the item is her favorite because she played with it right away.

Correct answer: B

Explanation: For a single-stimulus (single-item) preference assessment, the RBT records whether the client approaches or interacts with the item as defined by the BCBA. The RBT Task List requires following the operational definitions given by the supervisor. - B is correct because Sara’s reaching and playing with the toy meets the definition of approach/selection within 5 seconds. - A is incorrect because vocal requests are not required; the BCBA defined approach as physical interaction. - C is incorrect because the BCBA only specified what to do within 5 seconds, not a 1-minute requirement. - D is incorrect because deciding that an item is her “favorite” is an interpretation; the RBT’s job is to record behavior, not label preferences beyond the BCBA’s instructions.

Sample Question 4 — Assessment

Your BCBA is conducting a skills assessment with Jonah, a 7-year-old with developmental delays, to see what daily living skills he already has. The BCBA asks you to present specific tasks (like brushing teeth steps) and record exactly what Jonah does independently, with prompts, or not at all. During the assessment, what is your primary responsibility as the RBT?

  1. A. Change the order of the tasks based on what you think will be easiest for Jonah.
  2. B. Only present the tasks you think are most important for Jonah to learn.
  3. C. Follow the BCBA’s instructions for each task and record Jonah’s responses accurately and objectively. (Correct answer)
  4. D. Decide which new goals should be added to Jonah’s treatment plan based on his performance.

Correct answer: C

Explanation: When assisting with skills assessments, the RBT’s role is to follow the BCBA’s directions and collect accurate, objective data. This matches the Assessment section of the RBT Task List. - C is correct because it describes implementing the assessment as written and recording data without adding personal judgment. - A is incorrect because changing the order without direction may affect the assessment results and is a clinical decision. - B is incorrect because skipping tasks changes the assessment and is not within the RBT’s scope. - D is incorrect because selecting or writing goals is the BCBA’s responsibility, not the RBT’s.

Sample Question 5 — Assessment

You are assisting your BCBA with an assessment for Nina, a 5-year-old with autism. The BCBA is using a standardized language assessment and asks you to present picture cards and record whether Nina labels each picture correctly. During the assessment, Nina starts to get frustrated and looks away from the cards. What is the BEST action for you to take as the RBT?

  1. A. Give Nina extra prompts and hints so she can get more answers correct.
  2. B. Stop the assessment and decide to try a different assessment tool on your own.
  3. C. Follow the BCBA’s instructions for what to do if Nina is frustrated (for example, offer a short break) and continue to record her responses accurately. (Correct answer)
  4. D. Skip any items that seem too hard for Nina so she doesn’t get upset.

Correct answer: C

Explanation: When assisting with assessments, the RBT must follow the BCBA’s written and verbal instructions, including what to do if the client becomes frustrated, and continue to collect accurate data. This aligns with the Assessment and Professional Conduct sections of the RBT Task List. - C is correct because it keeps the RBT within their role: following the plan and recording data, including following any pre-planned break procedures. - A is incorrect because adding extra prompts changes the standardized assessment and may invalidate results. - B is incorrect because choosing a different assessment tool is a BCBA-level decision. - D is incorrect because skipping hard items changes the assessment and may give inaccurate information about Nina’s skills.

Sample Question 6 — Assessment

A BCBA asks you to help with a preference assessment for Maya, a 6-year-old with autism. The BCBA sets up three toys on the table and tells you to present two toys at a time and record which one Maya chooses. After each choice, you represent the chosen item with a new item. What is the MOST important thing you should do during this assessment?

  1. A. Let Maya keep all the toys she chooses so she doesn’t get upset
  2. B. Record each item Maya chooses on the data sheet exactly as it happens (Correct answer)
  3. C. Change the toys if you think Maya is getting bored, even if it’s not on the plan
  4. D. Only offer the toy you think she likes best so the data are clear

Correct answer: B

Explanation: This scenario describes a paired-stimulus (forced-choice) preference assessment designed by the BCBA. The RBT’s role (RBT Task List 2.0 – Assessment: Conduct preference assessments) is to follow the written procedure and collect accurate data. - B is correct because the RBT must carefully record each choice exactly as it occurs. Accurate data collection is essential so the BCBA can identify potential reinforcers. - A is incorrect because some preference assessments limit access to items or use brief access; the RBT should follow the written procedure, not automatically let the client keep all items. - C is incorrect because changing the toys without direction changes the assessment procedure and can make the results invalid. - D is incorrect because only offering one toy removes the comparison needed in a paired-stimulus assessment and does not follow the described procedure.
