Free Sample BCBA Exam Questions
Preparing for the BCBA exam requires mastering a wide range of behavior analysis concepts and applying them in real-world scenarios. With so much material to review, practice questions are one of the best ways to test your understanding and identify areas that need more study.
Below are two free sample BCBA questions from TrueLearn’s BCBA SmartBank to give you a preview of the type of questions you can expect while preparing for the exam.
Your First Free BCBA Sample Question and Answer
Which statement BEST illustrates the concept of prediction in behavior analysis as a natural science?
- A. Establishing a functional relationship between intervention and behavior
- B. Identifying consistent covariation between events to forecast behavior
- C. Inferring internal cognitive structures as causes of behavior
- D. Demonstrating causality through verbal report
The Answer and Explanation
Did you get it right? The correct answer is: B
Identifying consistent covariation between events to forecast behavior reflects the scientific goal of prediction. In behavior analysis, prediction involves observing that two events reliably occur together, which allows analysts to anticipate the likelihood of one event given the presence of another. Although this does not establish causation, it supports informed decision-making in applied contexts and serves as a foundation for further experimental investigation.
Behavior analysis is a natural science with the primary goals of description, prediction, and control of behavior. These goals are foundational to all scientific disciplines but are applied specifically to the study of behavior in applied behavior analysis (ABA).
| Goal | Definition | Example |
| Description | The systematic observation and measurement of behavior, identifying patterns and relationships between environmental events and behavior. | A researcher records how often a student raises their hand during class discussions. |
| Prediction | The ability to anticipate future occurrences of behavior based on observed correlations between variables. | Measuring both teacher praise and student participation—if data show that students who receive teacher praise participate more in class, we can predict that when students get increased praise, higher levels of participation will be observed. We cannot say that praise has caused an increase in participation, as correlation does not imply causation. |
| Control | Demonstrating a functional relationship by manipulating one variable (IV) to produce a reliable change in behavior (DV). | A teacher evaluates the effectiveness of a token system (IV) by comparing levels of homework completion (DV) in baseline (no token system) versus intervention (implementing the token system) in a research design such as reversal, multiple baseline, or multielement. |
| Abbreviations: DV, dependent variable; IV, independent variable. | ||
Incorrect Answer Explanations:
Answer A. Establishing a functional relationship between intervention and behavior refers to the goal of control, not prediction, which does not require intervention.
Answer C. Inferring internal cognitive structures as causes of behavior represents a mentalistic approach and is inconsistent with the observable, empirical methods of behavior analysis.
Answer D. Demonstrating causality through verbal report is not a valid method in behavior analysis, which relies on direct observation and measurable interactions with the environment.
Bottom Line
Prediction involves using observed, reliable correlations between events to anticipate behavior without assuming causation.

Your Second Free Sample BCBA Exam Question and Answer
Melanie, a behavior analyst, is working with a teacher to monitor how frequently students complete independent math assignments. Instead of observing students during work sessions, Melanie checks the number of fully completed worksheets turned in at the end of each period.
What type of measurement system is Melanie using?
- A. Indirect measurement
- B. Partial-interval recording
- C. Direct measurement
- D. Product measurement
The Answer and Explanation
Did you get it right? The correct answer is: D
Melanie is using product measurement (also known as permanent product recording) because she evaluates the physical outcome of the behavior—completed worksheets—rather than observing the behavior itself. This is appropriate when the product can be reliably and exclusively produced by the target behavior.
| Comparison of Measurement Types | |||
| Feature | Direct Measurement | Indirect Measurement | Product Measurement (Permanent Product) |
| What is measured | Behavior itself | Proxy, report, or summary | Outcome or artifact of behavior |
| Inference required | None | High | Moderate (depending on product-behavior correspondence) |
| Examples | Frequency, duration, latency | Rating scales, interviews, checklists | Worksheets, physical damage, countable outputs |
| Strengths | High validity, real-time data, low bias | Efficient, useful when behavior is covert or historical | Convenient, non-intrusive |
| Limitations | Resource-intensive | Low validity and reliability, subject to bias | Requires exclusive and consistent product link |
| Best use case | Real-time, observable behaviors | Pre-assessment screening, caregiver reporting | Observable outcomes of low-frequency or covert behavior |
Incorrect Answer Explanations
Answer A: Indirect measurement involves tools like interviews or rating scales and requires inference, which is not used in this case.
Answer B: Partial-interval recording is a form of direct, time-sampled measurement involving live observation, not used here.
Answer C: Direct measurement would involve observing and recording student behavior as it occurs in real time.
Bottom Line
Product measurement captures behavior outcomes and is effective when those outcomes provide a reliable, observable trace of the behavior without the need for real-time observation.
