BCBA Passing Score: Why There Is No Fixed Number to Hit

How the BACB sets the BCBA passing score

The passing score is a standard, not a curve. The BCBA Handbook says the BACB uses the modified Angoff method: a panel of BACB-certified subject matter experts determines the passing score against the knowledge expected of an entry-level behavior analyst, and the BACB Board of Directors approves it.

Two consequences follow from that, both stated by the BACB:

• Other candidates don't affect you. The method is criterion referenced, so your result depends on your own performance, not on how the people testing alongside you do.
• The cut is reset when the exam changes. The handbook says a new passing score is set when a significant change occurs, such as a new test content outline. The examination information page adds that new base forms are created about every five years or after such a change.

The current exam, on the 6th-edition outline since January 1, 2025, is therefore not scored against a cut from the older exam.

Why the number of correct answers can vary

Not everyone takes the same set of questions. According to the BACB's examination information page, the BACB builds many exam forms from a large pool, assigns candidates to them at random, and statistically equates every form to its base exam. In practice, a slightly harder form can require slightly fewer correct answers, and an easier one slightly more. That is why, in the BACB's words, the raw number of correct answers is not reported.

The BACB's scoring FAQ also describes scaled scores. A scaled score converts your number correct to a point on a scale, the way inches convert to centimeters, so the passing point stays at the same spot on the scale for every form. Scaling doesn't change who passes or fails, the FAQ says, and it publishes no scaled passing point.

"How many questions can you miss on the BCBA exam?"

There's no published answer, and nobody outside the BACB can calculate one. Here's what you can and can't work out:

A strong domain can make up for a weaker one, because only the overall total decides the result. But since you can't know where the line sits on your form, the safe strategy is to leave no domain weak, which is what domain-by-domain practice planned on the 6th-edition outline is meant to support.

Where the BCBA passing numbers online come from

Searches for "BCBA passing score" turn up confident numbers. Here is what checking them against BACB sources shows, as of October 27, 2026:

• "116 out of 150" or "77.33%." This one is real but historical. The BACB's January 2012 Newsletter reported that a passing-score panel recommended 77.33% correct, 116 of 150 items, for the September 2011 base exam, which was to be used through 2014. Today's exam has 175 scored questions on a newer outline, and the handbook says a new outline brings a new passing score.
• A scaled "400" or "445 of 500." These appear on third-party sites. Neither number appears on the BACB pages checked for this guide, so treat them as unverified.
• A fixed percentage per domain. The handbook contradicts this: the result is based on your overall performance.

What your BCBA result shows after the exam

The exam is pass/fail, and in most cases you see the result at the test center. The BACB can't view or download your result report, so you get a copy from your Pearson VUE account under "View Score Reports."

• If you pass. The BACB says passing candidates receive only notice that they passed, with no further report. Your certification number appears in your BACB portal account within 24 hours, and the BACB emails you about your certification within a week.
• If you don't pass. Your report shows the percentage of questions you answered correctly and the number of questions in each content area. A retake application appears in your BACB portal account within 48 hours.

The BACB adds a caution about that report: relatively few questions sit behind each part of it, so it may not predict how well you know that content, and you should restudy all of the content. The failed BCBA exam guide explains how to use it anyway.

Practicing without a published cut score

Since there's no number to aim at, a practical approach is to aim at coverage instead:

1. Measure by domain. Track your accuracy in each of the nine domains, not just an overall percentage. Once full prep launches, you can track your accuracy in each of the nine domains as you practice.
2. Fix the weakest domain first, weighting by its question count: at the same accuracy, a weak Behavior-Change Procedures (25 questions) costs more points than a weak Behaviorism and Philosophical Foundations (8).
3. Explain every miss. For each wrong answer, write why the right option is right and why your choice was wrong.
4. Rehearse the full sitting. A score on a short quiz says little about four hours. Plan at least one timed, full-length run.

No practice score, from Passy or anyone else, predicts a BACB result: practice questions aren't BACB items and aren't equated to its forms. Use them to find what to study. The 20 free BCBA practice questions cover all nine domains with an explanation for each answer.

For how many people actually pass, see how hard the BCBA exam is, by the BACB's pass rates. When you're ready for step 4, a timed four-hour rehearsal is planned for launch. Passy is independent of the BACB, and this guide reports only what the BACB publishes.
