NBCOT-COTA Pass Rate Analysis
COTA Exam Pass Rate: The Complete NBCOT Breakdown (2026)
The latest NBCOT pass rates for the certified occupational therapy assistant (COTA) exam, taken directly from the National Board for Certification in Occupational Therapy: first-time and all-new-graduates pass rates for OTA graduates, the three-year trend, how the COTA exam compares with the OTR exam, retake rules, fees, and what the numbers mean for your preparation. Every figure on this page is sourced from NBCOT certification activities data and the NBCOT exam handbook.
The Headline Numbers
What the NBCOT Data Actually Says
| Exam year | 2023 | 2024 | 2025 |
|---|---|---|---|
| First-time new graduates | 74% | 68% | 67% |
| All new graduates, any attempt within 1 year | 87% | 84% | 85% |
| First-time candidates tested | 3,439 | 2,932 | 2,806 |
| Total COTA administrations | 5,884 | 5,138 | 5,028 |
First Attempt vs One Year
The First-Attempt Rate Matches the OTR Exam. The Recovery Rate Does Not.
One in three new OTAs fails the COTA exam on the first try, and fewer of them recover within the year than their OT counterparts. Each retake costs a $385 fee and a 30-day wait.
“New graduates are candidates who tested within one year of their graduation date. All new graduates: pass rate regardless of the number of attempts. First-time new graduates: pass rate of candidates who passed on their first attempt.”
NBCOT reports two numbers for each exam: first time new graduates, who passed on the first attempt within a year of graduating, and all new graduates, who passed on any attempt within that year. The COTA and OTR exams have almost the same first-time pass rate, 67 and 68 percent in 2025. The difference is in the all new graduates figure. Within a year, 92 percent of new OTs are certified but only 85 percent of new OTAs are. The 18-point gap between the COTA first-time and one-year rates is smaller than the OTR gap, which means fewer COTA candidates who fail once come back and pass inside the year. Some are retaking later, some are working under a temporary license that will lapse, and some leave the field. Roughly 420 members of the 2025 OTA class were still uncertified twelve months after graduation.
That is the argument for first-attempt preparation on the COTA exam specifically. The retake path costs a $385 fee and a 30-day wait per attempt, a new authorization to test each time, and, for most new OTAs, a job offer that was contingent on passing. Our NBCOT-COTA study guide and study plan customizer are built around readiness before scheduling, not around a date on the calendar.
The Trend
Why the COTA Pass Rate Is Falling
NBCOT has not published a reason for the decline. Three factors are visible in the data. The January 2024 COTA blueprint concentrated 55 percent of the exam in Domain 2, selecting and implementing interventions under the OTR plan of care, and raised the share of six-option, three-correct multi-select items that award no partial credit. The 2023 to 2025 cohorts completed Level II fieldwork in the disrupted post-pandemic years. And the retake share of testing is rising: total administrations fell only 15 percent while first-time candidates fell 18 percent.
For a candidate, the lesson is practical. The exam is harder to pass on the first try than it was three years ago, the format rewards choosing the best intervention for this client at this stage over recalling a list, and the candidates who fail are not the ones who studied least. They are the ones who studied OTR-level evaluation content the COTA exam barely tests, or who scheduled before a diagnostic said they were ready. Treat the 67 percent as a warning, not a forecast.
Program Variation
OTA Program Pass Rates Vary Even More Than OT Programs
ACOTE requires every accredited OTA program to publish NBCOT results and keep its three-year average above 80 percent. The spread between programs is wide, and most programs publish the one-year rate, not the first-time rate.
Program pass rates vary far more than the national average suggests, and the spread is wider among OTA programs than among OT programs because cohorts are smaller and admissions are less selective. Because ACOTE requires every accredited occupational therapy assistant program to publish its NBCOT results, you can look up any OTA program’s three-year program outcomes directly: the graduation rate, the number of graduates who attempted the exam, and the NBCOT exam pass rates, usually reported as the all new graduates rate rather than the first-time rate. The top programs post 95 to 100 percent year after year; the bottom programs post rates in the 50s and 60s and risk ACOTE action when the three-year average falls under 80 percent.
Two cautions when you read program numbers. Most programs publish the one-year rate, which runs about 18 points higher than the first-time rate; a program advertising 85 percent is at the national average on first attempts. And small cohorts swing wildly: a program graduating 20 students moves five points every time one student passes or fails. Ask for all three years and for first-time results if the program tracks them, and read the graduation rate next to the pass rate: an OTA program that graduates 65 percent of its entering class and passes 95 percent of graduates is not a 95 percent program.
For current OTA students, the program rate sets expectations, not outcomes. Students at low-pass-rate programs pass on the first attempt every month with the right preparation, and students at top programs fail when they assume the program carries them. The variable is whether the study plan matches your actual gaps by domain, which is what a week-by-week NBCOT-COTA study plan built from a diagnostic does.
Retake Rules
What Happens When You Fail the COTA Exam
NBCOT retake rules are the same for the COTA and OTR exams: set by attempt number, with no lifetime cap.
After a failed attempt, NBCOT posts a performance feedback report to your MyNBCOT account with your overall score, where it fell against the passing threshold of 450, and your performance in each of the three domains. That report is the single most useful document in retake preparation: it tells you which domain fell below the entry-level standard, so your second attempt targets the gap instead of repeating the whole review. Read the current rules in the NBCOT certification exam handbook and the fee schedule before you reschedule.

What the Data Means for You
Translating Pass Rate Data Into COTA Exam Preparation Strategy
Pass rate data is most useful when it changes how you prepare. The strongest predictor of passing the COTA exam on the first attempt is whether your study plan is matched to your actual gaps by domain, with Domain 2 weighted the way the exam weights it, not how many hours you log or which review book you buy. First-time candidates who diagnose their weak domains early and target them with active recall and scenario-based practice consistently outperform candidates who run a generic question bank front to back.
For students at programs with average or below-average pass rates, the message is direct: program-level data does not determine your score. Your preparation quality, an honest assessment of your weak domains, and sitting for the exam when an objective measure says you are ready are the variables you control. Graduates from any ACOTE-accredited OTA program pass on the first attempt with the right approach, and the program-level spread proves it. Passing the COTA® exam earns COTA certification; state licensure requirements are a separate application to your state board, and most states require the NBCOT score plus a background check.
The numbers also argue against treating the COTA exam as the easier sibling of the OTR exam. Its first-time pass rate is the same, its one-year recovery rate is worse, and 15 percent of each OTA class is still uncertified a year after graduation. Build your preparation around your specific weaknesses, validate it with a full-length practice exam, and confirm readiness before you spend $515 on a registration. Our NBCOT-COTA study guide and study plan customizer are built for exactly that; the OTR data is in our NBCOT-OTR pass rate analysis.

FAQ
COTA Exam Pass Rate: Common Questions
NBCOT reports a 67% first-time pass rate for new graduates on the COTA exam in 2025 (2,806 first-time candidates), down from 68% in 2024 and 74% in 2023. Counting all attempts within one year of graduation, 85% of 2025 new OTA graduates passed. The figures come from the NBCOT certification activities page, which NBCOT updates each year.
On first attempts the two are nearly identical: 67% for COTA candidates and 68% for OTR candidates in 2025. The gap opens on the one-year rate: 85% of new OTA graduates were certified within a year versus 92% of new OT graduates. In other words, OTA candidates who fail once are less likely to recover within the year, which makes first-attempt preparation even more important on the COTA exam.
NBCOT has not published a cause. The first-time rate fell from 74% in 2023 to 68% in 2024 and 67% in 2025, the two years after the January 2024 blueprint took effect with its three-domain structure and 55 percent weighting on intervention implementation. First-time candidate volume also fell from 3,439 to 2,806 over the same period while the share of administrations that are retakes grew. Faculty most often point to the blueprint change, uneven Level II fieldwork, and candidates testing before they are ready.
NBCOT sets no maximum. Per the NBCOT certification exam handbook, you wait 30 days after your last exam date before attempts 2, 3, and 4; 60 days before attempts 5, 6, and 7; and 90 days before attempt 8 and beyond. Each attempt requires a new application and ATT letter. Some state licensing boards impose their own limits.
The initial online application is $515 ($555 by paper) and a retake application is $385 online ($415 by paper), per the NBCOT fee schedule, and each attempt needs a new authorization to test letter. The real cost of a failed attempt is usually the month or more of delayed start date, since most OTA job offers are contingent on COTA certification and the temporary license many states issue has a time limit.
The passing threshold is a scaled score of 450 on a 300 to 600 scale, the same passing score as the OTR exam. The 190-item exam format mixes single-response multiple-choice questions with six-option multi-select items, and the scaled score corrects for small differences between forms. There is no minimum per domain. See our NBCOT-COTA exam format guide for how scoring works.
ACOTE requires every accredited OTA program to publish its NBCOT pass rates and graduation rate on its own website, usually on a program outcomes page listing the number of graduates who took the exam and the percentage who passed within one year, for each of the last three years. Ask for all three years and, if the program tracks it, the first-time rate, which is typically 15 to 20 points lower than the one-year rate it publishes.
