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. You are developing a new program for a child who is both non-verbal (does not communicate using spoken or signed language) and non-vocal (does not produce sounds from their mouth). The goal is to teach the child to say ‘Mom.’ Given the child’s current skill set, what would be the absolute first step in shaping this vocal behavior?

Reinforce the client for making the ‘M’ sound in the presence of their mother.

Reinforce the client for any vocal sound made, regardless of its form or context.

Reinforce the client specifically when they approximate the ‘M’ sound.

Determine that shaping vocal behavior is not possible for a non-vocal child and explore alternative communication methods.

The text emphasizes the distinction between nonverbal and nonvocal and states that for a client who is nonvocal makes no sounds the very very basic first step in shaping vocal behavior is to reinforce any vocal sound they make This is the initial approximation when a learner has no existing skill in the target area Options A and C set expectations too high expecting an M sound or an approximation of it from a child who makes no sounds is not a realistic first step in shaping Option D is incorrect as the text explicitly refutes the assumption that shaping is impossible for nonvocal children affirming that behavior analysts know better and can shape such behaviors starting from the most basic approximations
