One of the most common questions BCBA candidates ask is: “What score do I need to pass?” It’s a fair question, especially if you’ve been studying for months and want to know exactly what it takes to cross the finish line.
Here’s what you need to know.
The BCBA exam uses a scaled scoring system.
To pass the BCBA exam, you need a scaled score of 400. The scale ranges from 0 to 500, and no matter which version of the exam you take, 400 is always the passing mark.
This passing score is set using a method called the modified Angoff method.
So what is the modified Angoff method?
It’s a scoring system used by many high-stakes credentialing exams. Here’s how it works: a panel of BACB-certified subject matter experts evaluates each test question and estimates how many entry-level behavior analysts would be expected to answer it correctly. Their evaluations are used to determine the raw score needed to pass. That raw score is then converted into a scaled score to account for slight differences in difficulty across different test versions.
This means:
- The passing score is criterion-referenced. You’re measured against a fixed standard, not other test-takers.
- Your score reflects your understanding of the material, not how others performed.
- A new passing standard is only set when there’s a major change in the exam, such as a new task list or industry updates.
What happens after you take the exam?
After you complete the exam at the testing center, you’ll typically receive a pass/fail result right away. If you pass, the BACB will generate your BCBA certification number within 24 hours, and it will appear in your BACB account.
You’ll also receive your official BCBA certificate by mail within 4 to 6 weeks. Make sure your mailing address is up to date in your BACB profile to avoid delays.
How should you interpret your score?
If you pass, congratulations!. You’ve met the standard.
If you don’t pass, you’ll receive a detailed score report that breaks down your performance across content areas. This is incredibly valuable for understanding what to focus on before your next attempt.
What about practice exams?
While practice exams don’t use scaled scoring, they’re still a great way to gauge your readiness. If you’re consistently scoring above 70% on full-length, high-quality practice tests, that’s a good sign you’re on track. More importantly, they can help you identify patterns in what you know and where you need more review. You can find practice exams with BCBA exam prep from AATBS.
Focus on mastering the material, use your practice scores as guidance, and go in knowing exactly what you’re working toward.
