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.

If you want to keep practicing, check out the BCBA section for more tests and study materials!

#1. A parent wants their child, who is highly resistant to wearing shoes, to eventually wear them comfortably for extended periods. Initially, the parent praises the child simply for touching the shoes. After the child consistently touches the shoes, the parent then praises the child for putting their foot partially into a shoe. Subsequently, praise is given for fully inserting the foot, then for wearing the shoe for a few seconds, and finally for wearing the shoes for longer durations. This systematic reinforcement of closer and closer approximations mirrors the parents’ strategy for Lisa learning to get into her car seat. The parent’s strategy of differentially reinforcing behaviors that progressively resemble the desired terminal behavior (wearing shoes comfortably) is an example of which behavior-change procedure?

Task Analysis

Chaining

Shaping

Fading

The parent is using shaping Shaping is a behaviorchange procedure in which differential reinforcement is applied to successive approximations toward a terminal behavior The behavior is gradually guided to a new form frequency duration or magnitude by reinforcing responses that are closer to the desired outcome and withholding reinforcement for previous approximations extinction for old approximations The text describes a very similar process for Lisa where parents are reinforcing approximations of this single response Task analysis involves breaking a complex skill into smaller teachable steps Chaining involves linking individual behaviors together to form a complex sequence Fading involves gradually reducing the prompt or stimulus control over a behavior until the behavior occurs naturally under the intended stimulus control
