Latest official annual data
2025 BCBA exam pass rate: 51% first-time, 23% retake
The numbers are useful, but only if read correctly. They describe groups of candidates who tested in 2025. They do not reveal a secret passing percentage, predict an individual result, or convert a mock score into official exam odds.
Pass-rate data are descriptive, not a diagnosis of your readiness. BACB does not endorse third-party mock exams, and no practice-score threshold on this site guarantees an official result.

2025 first-time result
9,955 first-time candidates tested and 51% passed.
2025 retake result
13,196 retake candidates tested and 23% passed.
What 51% does not mean
It is not the percentage of exam questions a candidate must answer correctly. It is a cohort pass rate.
Five years of official BCBA testing data
The 2025 first-time rate is the lowest in the five-year table shown on the BACB examination-information page. That is a reason to take preparation seriously, but the table does not identify a cause. Changes in candidate mix, training history, timing, examination content, and other variables cannot be separated from these aggregate rows.
60% first-time pass rate from 12,107 candidates
Retakes: 28% pass rate from 11,301 candidates.

Retakes: 24% pass rate from 8,575 candidates.
56% first-time pass rate from 8,255 candidates
Retakes: 23% pass rate from 10,450 candidates.
54% first-time pass rate from 9,911 candidates
Retakes: 25% pass rate from 11,780 candidates.
51% first-time pass rate from 9,955 candidates

Why the pass rate is not the passing score
BACB describes its examination standard as criterion referenced. A panel of certified subject matter experts establishes the passing standard for a base form using the modified Angoff method, and different forms are statistically equated. The raw number correct required for one form can therefore differ from another form. Scores are then placed on a common scale.
This is why statements such as “you need 70%” or “a 75% mock guarantees a pass” are not supported by the official scoring explanation. A third-party percentage can still be useful, but its honest use is narrower: find what you miss, check whether improvement transfers to unseen questions, and test whether your pacing survives a long mixed set.
A 51% pass rate means you need 51% correct to pass.
It does not. The pass rate is the percentage of first-time candidates who passed in 2025. BACB uses a criterion-referenced process and equates different exam forms; it does not publish one universal raw number correct that guarantees a pass.
My mock score can be converted directly into an official pass probability.
A commercial or free mock is not an equated BACB exam form. Its score can reveal weak domains, pacing, and error patterns, but it cannot reproduce the official passing standard.
The lower retake rate proves retakers are less capable.
The groups differ in important ways, and the published table does not explain each candidate's preparation, training, prior score, or number of attempts. The statistic supports caution, not a judgment about an individual.
The overall pass rate tells me whether my university is good.
BACB publishes separate university pass-rate reports and warns against treating the overall examination rate as a direct benchmark for comparing programs. Use the program-specific report and understand its cohort size.
What the retake data should change about preparation
A retake should not become the same study plan with more hours. The 23% cohort rate does not say why any one candidate failed, but it does make one practical point: repeating a familiar routine is not enough evidence that the underlying problem has changed. Start with the official score report, then separate content gaps from scenario discrimination, pacing, answer changing, and weak review habits.
Better readiness evidence than one mock percentage
- Your performance is stable across several mixed sets, not dependent on seeing familiar questions.
- You can explain why the second-best option is premature, unsupported, or outside the decision point.
- Weak domains identified in diagnostics improve after targeted review and remain improved when mixed back into broader practice.
- You can sustain careful reading under timed conditions without a late-session collapse in unanswered questions or impulsive changes.
- You know the 6th-edition domain blueprint and have not ignored low-confidence areas simply because their percentage is smaller.

Frequently asked questions
What was the BCBA exam pass rate in 2025?
BACB reported a 51% pass rate among 9,955 first-time BCBA examination candidates and a 23% pass rate among 13,196 retake candidates in 2025.
Was the 2025 first-time BCBA pass rate lower than 2024?
Yes. The official table reports 54% for first-time candidates in 2024 and 51% in 2025. The table alone does not establish why the rate changed.
What score is needed to pass the BCBA exam?
BACB uses the modified Angoff method and statistical equating. Because forms can differ in difficulty, the raw number correct required to pass may vary, and BACB does not report a universal raw cut score.
Is a 70% mock exam score enough to pass the BCBA exam?
No independent mock percentage guarantees an official result. Use mock performance as evidence about pacing, domain coverage, and repeatable reasoning, not as a direct conversion to the BACB passing standard.
