BCABA Quick-Start 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-Change Procedures

Noncontingent reinforcement (NCR) involves:

  1. A. Delivering a reinforcer only after the client performs a specified target behavior
  2. B. Delivering a reinforcer on a time-based schedule, independent of the client's behavior (Correct answer)
  3. C. Withholding reinforcement for the problem behavior while reinforcing an alternative
  4. D. Removing a reinforcer each time the client engages in the target problem behavior

Correct answer: B

Explanation: B is correct because NCR provides reinforcers on a fixed-time or variable-time schedule regardless of what the client is doing, which can reduce motivation for problem behavior. A describes contingent reinforcement. C describes differential reinforcement of alternative behavior with extinction. D describes negative punishment, such as response cost.

Sample Question 3 — Behaviorism and Philosophical Foundations

During the first week of a new case, a BCaBA records how often a client leaves their seat, the activities in progress, and the times of day it happens. No conditions are changed, and no relations between variables have been analyzed yet. Which goal of behavior analysis as a science does this activity MOST directly serve?

  1. A. Description, because it produces systematic, quantifiable observations of behavior (Correct answer)
  2. B. Prediction, because the records will show when leaving the seat is likely to occur
  3. C. Control, because the data will later be used to change the classroom environment
  4. D. Replication, because the observations are repeated across a full week of sessions

Correct answer: A

Explanation: A is correct because description involves systematic observations that can be quantified and classified, which is what the BCaBA is doing before any relations are analyzed. B requires repeated observations showing that two events reliably covary. C requires manipulating a variable to demonstrate a functional relation. D is not one of the three goals of the science (description, prediction, control); replication is a scientific practice used to establish the reliability of findings.

Sample Question 4 — Concepts and Principles

A single instance of a client raising their hand during group instruction is BEST described as a:

  1. A. Behavioral repertoire
  2. B. Stimulus class
  3. C. Response (Correct answer)
  4. D. Response class

Correct answer: C

Explanation: C is correct because a response is a single, specific instance of behavior. A refers to all of the behaviors a person can do, or a set of behaviors relevant to a skill area. B refers to a group of stimuli that share common features or functions, not to behavior. D refers to a group of responses that share a common function or form, not a single instance.

Sample Question 5 — Ethical and Professional Issues

Which of the following is one of the core principles of the Ethics Code for Behavior Analysts?

  1. A. Treat others with compassion, dignity, and respect (Correct answer)
  2. B. Defer to the most senior professional on the team
  3. C. Guarantee positive outcomes for every client served
  4. D. Prioritize the interests of the employing organization

Correct answer: A

Explanation: A is correct because treating others with compassion, dignity, and respect is one of the core principles, along with benefiting others, behaving with integrity, and ensuring competence. B is not a core principle; deferring to seniority does not replace ethical judgment. C is not a core principle; behavior analysts cannot guarantee outcomes. D is not a core principle; behavior analysts' primary obligation is to clients.

Sample Question 6 — Experimental Design

In a study evaluating a behavior-change procedure, the independent variable is:

  1. A. The participant whose behavior is being studied
  2. B. The condition that is systematically manipulated (Correct answer)
  3. C. The target behavior that is measured throughout the study
  4. D. An uncontrolled event that happens to occur during the study

Correct answer: B

Explanation: B is correct because the independent variable is the variable the experimenter or practitioner deliberately changes to see its effect on behavior. A is the person involved in the study, not a variable that is manipulated. C describes the dependent variable. D describes a potential confounding variable, not the independent variable.

Sample Question 7 — Intervention Development and Monitoring

Which goal is stated in observable and measurable terms?

  1. A. Given the instruction "wash hands," the client will complete all 6 steps in 4 of 5 opportunities (Correct answer)
  2. B. The client will develop a better understanding of why good hygiene matters at home and school
  3. C. The client will become much more independent in the bathroom over the next several months
  4. D. The client will feel more confident and comfortable about washing hands before every meal

Correct answer: A

Explanation: A is correct because this goal specifies the condition, an observable behavior, and a measurable criterion. B describes an internal state ("understanding") that cannot be directly observed or measured. C is vague about what behavior is expected and how independence will be measured. D describes feelings rather than observable behavior with a measurable criterion.

Sample Question 8 — Measurement, Data Display, and Interpretation

The amount of time between the onset of an instruction and the beginning of the client's response is called:

  1. A. Rate
  2. B. Latency (Correct answer)
  3. C. Duration
  4. D. Interresponse time

Correct answer: B

Explanation: B is correct because latency is the time between the onset of a stimulus, such as an instruction, and the initiation of the response. A is the number of responses per unit of time. C is the amount of time from the beginning to the end of a response. D is the time between the end of one response and the beginning of the next instance of the same response.

Sample Question 9 — Supervisory Relationships

Which is a potential risk of ineffective supervision?

  1. A. More accurate data collection across all staff members
  2. B. Increased employee job satisfaction and retention
  3. C. Faster mastery of skills by supervisees and clients
  4. D. Poor client outcomes (Correct answer)

Correct answer: D

Explanation: D is correct because ineffective supervision can lead to poor implementation of procedures, which harms client outcomes. A is an outcome of effective supervision rather than a risk of ineffective supervision. B is the opposite of a risk; effective supervision is associated with improved satisfaction and retention. C is a benefit of effective supervision, not a risk of ineffective supervision.

Sample Question 10 — 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.
