BCABA Behavior Assessment Sample Questions with Answers

Sample Question 1 — Behavior Assessment

At the outset of a new case, which records are MOST important to review for possible medical contributions to a client's problem behavior?

  1. A. Billing records showing the client's past authorized service hours
  2. B. Staff schedules listing who will work with the client in upcoming weeks
  3. C. The funding source's list of approved service codes for the client's plan
  4. D. Medical records, including current diagnoses and medications (Correct answer)

Correct answer: D

Explanation: D is correct because medical records can reveal health conditions or medication effects that may influence behavior and should be considered before assessment and intervention. A show administrative information but do not identify medical variables that may affect behavior. B are useful for planning sessions but contain no information about medical contributions to behavior. C concerns billing and authorization rather than medical factors affecting behavior.

Sample Question 2 — Behavior Assessment

Why should a BCaBA review available records before conducting assessments on a new case?

  1. A. To identify relevant history and prior interventions that may influence assessment and intervention (Correct answer)
  2. B. To determine the billing rate that should be charged to the client's funding source
  3. C. To decide whether the client's family is likely to cooperate with recommended procedures
  4. D. To replace the need for direct observation and other assessments of the client's behavior

Correct answer: A

Explanation: A is correct because records can reveal medical, educational, and behavioral history, including what has already been tried, which helps guide assessment planning. B is not the clinical purpose of reviewing records at the outset of a case. C is not the purpose of a records review and could introduce bias about the family. D is wrong because records supplement, rather than replace, direct assessment.

Sample Question 3 — Behavior Assessment

Educational records show that a student's aggression began three months ago, the same week the student moved to a new classroom with a new teacher. How should a BCaBA use this information?

  1. A. Note the timing as a possible contributing variable to explore during assessment (Correct answer)
  2. B. Recommend moving the student back to the previous classroom before any assessment is done
  3. C. Conclude that the new teacher is causing the aggression and recommend a teacher change
  4. D. Disregard the history, because only current direct observation data are relevant to assessment

Correct answer: A

Explanation: A is correct because a change that coincides with the onset of behavior is a useful lead for assessment, but it is a hypothesis that needs to be evaluated rather than a conclusion. B makes an intervention decision based on an untested assumption. C treats a correlation in the records as a confirmed cause without assessment. D ignores useful information that can guide the assessment.

Sample Question 4 — Behavior Assessment

A client's records describe several previous behavior plans for self-injury that used different strategies, with data showing that none of them were effective. What is the MOST useful way to use this information?

  1. A. Conclude that the client's self-injury cannot be changed with behavioral procedures
  2. B. Review what was tried and why it may have failed, and plan assessment with the supervisor (Correct answer)
  3. C. Ignore the previous plans, because they were written by other providers with different methods
  4. D. Repeat the most recent plan, because the new team may implement it more consistently than before

Correct answer: B

Explanation: B is correct because knowing what has been tried, and the data on those attempts, can help the team avoid repeating ineffective approaches and identify what to assess. A is an unwarranted conclusion based on past plans that may not have been function-based or well implemented. C discards information that could make the new assessment more efficient and effective. D ignores data showing that the plan was not effective, without evaluating why.

Sample Question 5 — Behavior Assessment

Medical records show that a client recently started a medication whose possible side effects include agitation and sleep problems. The client's aggression increased during the same month. What is the BEST action?

  1. A. Share the information with the supervisor, recommend coordination with the prescriber, and keep collecting data (Correct answer)
  2. B. Recommend that the family stop the medication until aggression returns to its previous level
  3. C. Conclude that the aggression is maintained by attention, because it increased when routines changed
  4. D. Disregard the medication change, because aggression is a behavioral problem rather than a medical one

Correct answer: A

Explanation: A is correct because possible medication effects should be considered with the supervisor and relevant medical providers, while data collection continues to inform decisions. B is outside the BCaBA's scope and could put the client at risk. C draws an unsupported conclusion about function and ignores the possible medication effects. D ignores a potentially important variable that could be contributing to the change in behavior.

Sample Question 6 — Behavior Assessment

Records from a previous provider describe a client's problem behavior as "attention-seeking," but they include no data or description of how this conclusion was reached. How should the BCaBA treat this information?

  1. A. As sufficient justification to begin an attention-based intervention immediately
  2. B. As a hypothesis to be evaluated through current functional assessment (Correct answer)
  3. C. As irrelevant information that should be removed from the client's file
  4. D. As the confirmed function of the behavior, because it came from a qualified provider

Correct answer: B

Explanation: B is correct because undocumented conclusions about function may be inaccurate or outdated, so they should be tested rather than accepted as established. A skips the assessment needed to confirm the function of the behavior. C discards possibly useful information and may conflict with record-keeping requirements. D accepts a conclusion without supporting data or an indication of how it was determined.

Sample Question 7 — Behavior Assessment

Which situation MOST clearly warrants behavior-analytic services?

  1. A. An adult prefers to take the same route to the grocery store each week
  2. B. A teenager enjoys playing video games for an hour after completing homework
  3. C. A client's self-injury is interfering with learning and daily living activities (Correct answer)
  4. D. A child cries briefly when a favorite television show ends each evening

Correct answer: C

Explanation: C is correct because behavior that causes harm and interferes with the client's learning and daily functioning is socially significant and warrants services. A describes a harmless preference that does not interfere with daily life. B describes a typical leisure activity that does not interfere with other responsibilities. D describes a common, brief reaction that does not by itself indicate a need for services.

Sample Question 8 — Behavior Assessment

A parent requests services because their typically developing 4-year-old occasionally refuses vegetables at dinner. The child's pediatrician reports no weight or health concerns. What is the MOST appropriate response?

  1. A. Begin an intensive feeding intervention, because any food refusal can become a serious problem
  2. B. Ask the supervisor whether services are warranted or guidance or referral fits better (Correct answer)
  3. C. Tell the parent that food refusal is never an appropriate target for behavior analysts
  4. D. Recommend a functional analysis of food refusal before discussing the concern with anyone else

Correct answer: B

Explanation: B is correct because occasional food refusal with no health concerns may be developmentally typical, so the supervisor should help determine whether behavior-analytic services are needed. A assumes a need for intensive services without evidence that the behavior is significant. C is inaccurate, because significant feeding problems can warrant behavior-analytic services. D skips the step of determining whether services are warranted and involving the supervisor.

Sample Question 9 — Behavior Assessment

A teenage client shows sudden weight loss, withdrawal from preferred activities, and frequent statements of hopelessness. What is the MOST appropriate action?

  1. A. Add a token system to increase eating and participation in preferred activities
  2. B. Collect data for several more weeks before sharing the concerns with the supervisor
  3. C. Tell the supervisor promptly so a medical or mental health referral can be made (Correct answer)
  4. D. Place the statements of hopelessness on extinction to reduce their frequency

Correct answer: C

Explanation: C is correct because these signs may indicate conditions requiring medical or mental health evaluation, which is outside the scope of behavior-analytic services alone. A addresses symptoms behaviorally without ensuring that possible medical or mental health needs are evaluated. B delays action on signs that may indicate a serious problem. D could ignore a serious risk and fails to ensure appropriate professional evaluation.

Sample Question 10 — Behavior Assessment

Which factor is MOST relevant when deciding whether a behavior warrants intervention?

  1. A. Whether it poses risk or limits the client's quality of life, learning, or access (Correct answer)
  2. B. Whether staff members find the behavior annoying or inconvenient to manage during the day
  3. C. Whether the behavior looks unusual to people who are unfamiliar with the client
  4. D. Whether the client's funding source will cover intervention for that specific behavior

Correct answer: A

Explanation: A is correct because behavior-analytic services are warranted when behavior is socially significant for the client, such as when it causes harm or limits opportunities. B focuses on staff convenience rather than the behavior's significance to the client. C reflects the reactions of others rather than the effect of the behavior on the client's life. D is an administrative consideration, not the basis for determining whether intervention is warranted.
