BCBA Practice Questions That Explain Every Option
Most question banks tell you which answer was right. These tell you why the one you picked was wrong. Every option carries its own rationale, so the three you did not choose teach you something too.

A Real Question from the Bank
This is an actual practice item, shown exactly as it appears after you answer. Note that all four options are explained, not just the correct one.
A researcher repeatedly observes that aggression is more likely during difficult tasks than during leisure but has not manipulated task difficulty. Which scientific goal is best demonstrated?
Why not: Control requires systematic manipulation with a demonstrated functional relation.
Correct: Reliable covariation supports prediction but not experimental control.
Why not: Selectionism is a philosophical assumption, not one of the three scientific goals.
Why not: The observations go beyond description by identifying a reliable relation.
Key concept. Description identifies orderly events, prediction identifies reliable covariation, and control is demonstrated when manipulation of a variable produces reliable behavior change.
There are 1,350 practice items in the bank, written across all nine domains of the BCBA 6th-edition Test Content Outline and tagged to the individual task list items underneath them.
Why Per-Option Explanations Matter
You learn from the miss
Being told the answer was B does not tell you what was wrong with your reasoning. The rationale for the option you actually picked does.
Distractors are the lesson
Exam questions are built so the wrong options are tempting for a specific reason. Each rationale names that reason instead of leaving you to guess it.
Practice adapts to you
The areas you miss most come back more often, so your practice time goes where it changes your score rather than where you are already solid.
