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. Terry wants to teach his daughter to prepare basic meals so she can develop independent living skills. He creates a detailed task analysis for meal preparation. A known challenge for his daughter is that she frequently quits, attempts to escape the task, or exhibits frustration when steps in the middle of a task become difficult. To maximize the likelihood of her completing the task and to strategically leverage her tendency to quit difficult steps by providing quicker access to task completion, which task chaining procedure would be most advantageous for Terry to employ?
Selecting the appropriate chaining procedure is crucial for skill acquisition especially when dealing with specific learner characteristics like escape behavior Forward Chaining involves teaching the first step of the task analysis then the first two steps and so on Reinforcement is delivered upon successful completion of the mastered steps This method can be slow to reinforcement particularly for long tasks and might exacerbate escape behavior if difficult steps are encountered early without immediate access to the completion of the task Total Task Chaining teaches all steps of the task analysis in every trial providing prompts as needed for unmastered steps While comprehensive if the daughter struggles with multiple steps and is prone to quitting requiring her to perform most or all steps before reinforcement could also lead to high rates of escape and frustration Behavior Chain Interruption Strategy BCIS is an assessment and intervention technique used to determine if a behavior serves as a reinforcer or to teach new skills by introducing a novel stimulus into a chain However its primarily an intervention for existing chains or for assessing function not the most direct or initial teaching strategy for a novel chain especially if the goal is to prevent escape from difficulty Backward Chaining is the most advantageous in this scenario In backward chaining the trainer performs all but the last step of the task analysis and the learner then completes only the final step This immediately leads to the natural reinforcer eg the meal is prepared the task is done Once the last step is mastered the trainer performs all but the last two steps and the learner completes those two and so on This method is highly effective for learners who are prone to escape behavior or low motivation because the completion of the chain and thus the escape from the task demand is immediately available after performing only the final often easiest step This makes the reinforcement very salient and readily accessible helping to build momentum reduce the likelihood of quitting and minimize frustration by frontloading the support for the more challenging initial and middle steps
