BCBA® exam prep · 6th Edition TCO

The problem

The BCBA exam is getting harder to pass.

First-time pass rates have fallen every year since 2020. For candidates who retake, the odds are worse.

51%
First-time pass rate in 2025 — the lowest the BACB has ever recorded.
23%
Pass rate for retake candidates in 2025. Studying harder the same way rarely works.
13,196
Retake attempts in 2025 — more than the 9,955 first-time attempts.

How it works

Measure first. Then intervene.

The same logic you'll use as a behavior analyst: take a baseline, find what's maintaining the problem, and change the plan based on data.

FAQ

Questions

Is the content aligned with the current BCBA exam?

Yes. Every question is mapped to a task of the BCBA 6th Edition Test Content Outline, which applies to exams from 2025 onward, and ethics questions follow the current Ethics Code for Behavior Analysts.

Are these real BCBA exam questions?

No. Real exam items are confidential, and anyone selling them is violating BACB rules. Our questions are original, written to match the format, difficulty and content of the exam.

I already failed the BCBA exam once. Will this help?

That's exactly who we built it for. Your score report shows domain-level results — Baseline shows which concepts inside those domains are breaking down, so you stop re-studying what you already know.

Is there a limit on practice or mock exams?

No. Practice sets and timed mock exams are unlimited for as long as you have access — until you pass, including retakes. The AI tutor allows up to 60 messages per day.

How does the pass guarantee work?

Work through the question bank and complete at least two full-length mock exams. If you still don't pass, email us your score report within 30 days of your exam and we'll refund you in full. There's also a 14-day no-questions refund.

Is this a subscription?

No. It's a single one-time payment with access until you pass. Checkout is handled securely by Paddle and accepts cards, Apple Pay, Google Pay and PayPal.

Start with your baseline.

Fifteen minutes. Eighteen questions. A clear picture of which domains would cost you the exam — free, no sign-up.
