Getting ready for your BCBA exam? You’re in the right place.
I created RBTExamPrep.com to give you the most realistic BCBA mock exam experience possible 185 questions designed to feel just like the real thing.
My goal isn’t just to help you pass, but to help you understand every concept deeply.
Whether you get a question right or wrong, you’ll see detailed feedback explaining why, so you’ll be ready for that type next time. I want you to walk into test day feeling confident, calm, and prepared.
Many students have shared that these questions felt almost identical to the real exam and that’s exactly what I was aiming for. I’d love to hear how you did please share your score in the comments below! It really helps encourage others who are preparing for the exam. 🙂
I built this site to keep high-quality BCBA prep resources free and accessible for everyone, which is why it’s supported by ads. If it helped you, it’d mean a lot if you shared it with your peers.

#1. Marshall, a Board Certified Behavior Analyst (BCBA), begins to observe a consistent pattern in his personal life his partner, Lily, tends to offer compliments about his appearance more frequently on days when he has diligently flossed and brushed his teeth. Intrigued by this potential relationship, Marshall decides to keep a detailed log for several weeks. He records each day he flosses and brushes his teeth and also marks down every instance Lily compliments him, noting any co-occurrence of these two events. Marshall is not intentionally altering his dental hygiene routine for this observation he is simply documenting what naturally happens. Considering the three primary goals of science in Applied Behavior Analysis (Description, Prediction, and Control), what type of analysis is Marshall conducting?
Marshalls actions align directly with a correlational analysis In this type of analysis an observer systematically tracks two or more variables to see if they covary or are related without any active manipulation of an independent variable The goal of correlational analysis is to establish a prediction meaning if one variable occurs we can predict the likelihood of the other variable occurring Marshall is observing a naturally occurring relationship between his dental hygiene and his partners compliments and he is explicitly not manipulating his behavior Lets clarify the different types of analysis and their relation to the goals of science Descriptive Analysis Goal Description This involves observing and documenting a single variable or behavior without any attempt to establish relationships or causality If Marshall were only recording when Lily complimented him without considering his dental hygiene that would be a descriptive analysis Correlational Analysis Goal Prediction This involves observing two or more variables to determine if a systematic relationship or covariation exists between them There is no manipulation of variables its about identifying patterns that allow for prediction This is precisely what Marshall is doing by noting the cooccurrence of his dental hygiene and Lilys compliments Experimental Analysis Goal Control This involves systematically manipulating one or more independent variables to determine their effect on a dependent variable The aim is to establish a causeandeffect relationship If Marshall were to intentionally increase or decrease his flossingbrushing to see if it caused a change in compliments he would be conducting an experimental analysis Functional Analysis While a type of experimental analysis it is specific to identifying the function purpose of a challenging behavior by systematically manipulating antecedents and consequences in a controlled environment This is not what Marshall is doing in this scenario as he is observing a positive social interaction not a problem behavior and not systematically manipulating environmental conditions to test functions
