BCBA Pass Rate Hits Record Low as Demand Doubles

The Numbers Behind the Decline

In 2020, two-thirds of the first-time candidates passed the Board Certified Behavior Analyst examination. In 2025, barely half did. The Behavior Analyst Certification Board’s annual data reports trace an unbroken slide: 66 percent in 2020, 56 percent in 2023, 54 percent in 2024, and 51 percent in 2025, the lowest first-attempt rate the board has published.

Volume moved the other way. First-time candidates grew 51 percent over those five years, from 6,583 in 2020 to 9,955 in 2025, according to BACB annual report data. The retake pool more than doubled, from 6,166 to 13,196, while the retake pass rate fell from 31 percent to 23 percent. In all, 23,151 people sat for the BCBA exam in 2025. The field certified 8,021 new BCBAs.

The gate is narrowing while the line outside it lengthens. That combination matters because the exam is the industry’s sole supply valve: employers posted 132,307 BCBA jobs in 2025, up 28 percent year over year, against roughly 83,600 active BCBA certificants as of April 2026, about 1.6 open positions per credential holder. A field that needs every qualified clinician it can train is losing nearly half of its candidates at the final step.

Where the Candidates Come From

The most rigorous public anatomy of the pipeline comes from a peer-reviewed study by Erick Dubuque and Ellie Kazemi in Behavior Analysis in Practice, which analyzed BACB-published pass-rate data from 2013 to 2020. Its central finding: 99.97 percent of first-time BCBA candidates completed their coursework through a Verified Course Sequence, the content-hour verification track, rather than through an accredited degree program. Of the 20 course sequences producing the most exam candidates, exactly one sat inside an ABAI-accredited program.

Production is heavily concentrated. Across the study period, 32,929 first-time candidates came from 223 course sequences, but a single program supplied 15 percent of them and nine programs supplied half. Concentration persists in the current data: the BACB’s 2024 university pass-rate report covers 192 training programs, with first-time pass rates ranging from 0 to 100 percent, and Ball State University alone accounted for 832 first-time candidates, with a 53 percent pass rate. The BACB itself cautions against comparing any program to the overall average precisely because a handful of very large programs dominate the aggregate.

Delivery mode tracks the gap. In the Dubuque and Kazemi data, candidates from campus and hybrid programs passed at 73 percent on their first attempt, while candidates from fully online course sequences passed at 60 percent, and online sequences supplied 56 percent of all candidates. Earlier analyses summarized in the same paper by Shepley and colleagues in 2017 and by Guinness and Turner in 2021 found campus instruction and ABAI accreditation associated with higher pass rates, while larger program size was weakly associated with lower ones.

Read together, the data describe an aggregate pass rate that is substantially a function of a small set of very large, mostly online, mostly non-accredited programs. The national number is less a verdict on the exam than a weighted average of where the field buys its training.

A New Exam, an Old Trend

The exam itself changed in January 2025. The BACB retired its edition task lists and adopted the 6th Edition Test Content Outline, which reweights content across domains; the cut score, set by the modified Angoff method, requires a scaled score of 400 out of 500. New-era pass rates are not strictly comparable to old ones, and some portion of the three-point drop from 2024 to 2025 plausibly reflects candidates and programs adjusting to a different instrument.

The transition cannot carry the trend, though. The slide has now run continuously through two exam changes: rates fell through the 2022 move to the 5th Edition Task List and kept falling into the 2025 outline, and twelve of the fifteen percentage points of decline, from 66 percent in 2020 to 54 percent in 2024, accumulated before the new exam existed. Whatever is eroding first-attempt performance predates the instrument now being blamed for it.

Twelve of the fifteen points of decline accumulated before the new exam existed. The slide is a trend, not a transition artifact.

The 2032 Consolidation Bet

The field’s structural answer is already law inside the credentialing system. The Verified Course Sequence system sunset on December 31, 2025; ABAI stopped accepting new VCS applications in January 2025. Since January 2026, coursework-based candidates qualify through a BACB-managed attestation system, in which a full-time, BCBA-certified faculty member vouches that a program’s coursework meets requirements. That bridge, Pathway 2, closes after December 31, 2031. From January 1, 2032, per the BACB, only degrees from programs accredited by ABAI or APBA will qualify a candidate for BCBA certification.

Accreditation is a different test than verification ever was. A VCS confirmed content hours; accreditation is a peer review of curriculum, faculty, experiential training, and program outcomes. The bet is that forcing all training through that filter raises the floor.

The risk is capacity. As of December 2023, only 26 universities held accredited master’s programs, and 40 accredited programs existed at all levels, per an ABA Technologies analysis, which projected the count would rise as the 2032 requirement approaches. Set those figures against the 192 programs in the BACB’s 2024 pass-rate report and a candidate population that came almost entirely through the coursework track, and the arithmetic is tight: the accredited tier must absorb, by 2032, nearly the whole of a pipeline it barely touches today. Online programs, which supply most candidates, could pursue accreditation only starting in 2022.

The field is betting its training pipeline on accredited programs that today produce a small fraction of its candidates.

What Operators Should Watch

For employers, the pass-rate slide is a hiring problem with a lag. Demand has more than doubled since 2023, when postings stood at roughly 65,300, and at 2025 volume, each percentage point of first-attempt pass rate represents roughly 100 clinicians a year who either enter the workforce or join a retake pool where three of four fail. Candidates get up to eight attempts within a two-year authorization window, with a 30-day wait between attempts, so a failed first attempt often leaves a supervisee stuck in limbo on an organization’s payroll.

That turns program choice into underwriting. Organizations that fund BCBA-track staff through tuition assistance and supervised fieldwork are financing a bet on a specific program’s conversion rate, and the BACB publishes exactly that number, program by program, every year. Screening a partner program’s first-time pass rate, its delivery mode, and its accreditation trajectory toward 2032 is now as basic as credential verification.

The next test of the trend arrives with the BACB’s 2026 annual data report, expected in early 2027, the second full year under the new outline. If the first-time rate stabilizes, 2025 reads as a transition. If it keeps falling, the problem was never the exam.
