How Hard Is the NBCOT OTR Exam? NBCOT's Pass Rates and What Makes It Hard

Most graduates do pass the OTR exam, but enough first attempts fail that it deserves a serious plan. NBCOT's own numbers put the first-attempt pass rate for new graduates at 68% in 2025. Below are the official figures, what they do and don't mean, and the specific features of the exam that make it hard.

NBCOT's OTR pass rates for 2023 to 2025

NBCOT publishes two pass rates for new graduates on its certification activities page, checked on October 27, 2026. A "new graduate" is a candidate who tests within one year of their graduation date.

• First-time new graduates: the percentage who passed on their first attempt.
• All new graduates: the percentage who passed, regardless of the number of attempts.

NBCOT also reports 14,732 OTR exam administrations in 2025, a count that includes repeat attempts by the same person, and 169,736 people holding the OTR certification that year. The candidate counts in the two columns don't line up exactly (in 2023 and 2024 the first-time group is the larger one), and NBCOT doesn't explain why, so compare the rates rather than the head counts.

What the 68% and the 92% tell you

Read together, the two rates say something useful: roughly a third of new graduates didn't pass on the first try in 2025, yet the gap between 68% and 92% suggests most of them passed on a later attempt within a year of graduating. A failed first attempt is common, and it is usually not the end of the road. The retake guide covers the waiting periods if that's where you are.

What the figures can't do:

• They don't predict your result. They describe large groups, and the passing standard applies to you alone
• They cover new graduates only. NBCOT's page gives no rate for people testing more than a year after graduating or for internationally educated candidates
• They don't explain the 2024 drop. The first-time rate fell from 73% in 2023 to 68% in 2024, the year the exam moved to the 2022 content outline and replaced clinical simulation items with scenario sets on January 2, 2024 (2024 Exam FAQ). NBCOT's page gives no reason for the change, so treat the timing as context, not as a cause

You also aren't competing with the other candidates. NBCOT's Foundations page says the exam is criterion-referenced: everyone who reaches the passing standard passes, however many people do. The passing score guide explains what that standard is.

For context, the COTA exam for occupational therapy assistants, a different test, shows a similar pattern on the same page: 67% of first-time new graduates and 85% of all new graduates passed in 2025.

Finding your OT program's NBCOT pass rate

NBCOT's School Performance Data tool lets you pick a state, a program type (OT doctoral-level or OT master's-level) and a year from 2021 to 2025. One detail changes how to read it: NBCOT says a program's passing percent counts new graduates who passed "regardless of the number of attempts during the testing year," to meet ACOTE's reporting standard.

So a program that reports 95% should be compared with NBCOT's national all-attempts rate (92% in 2025), not with the 68% first-time rate. Many program websites publish the same figure. A high program rate is good news, but it doesn't tell you how many classmates passed on the first try.

What makes the NBCOT OTR exam hard

Several features combine, and each one points to a different kind of preparation.

It tests application, not recall. NBCOT says its items, written by OTR subject matter experts, "focus on application of knowledge." In practice, expect items that describe a client and a situation and ask what the therapist should do or what a finding means. Knowing a definition rarely settles them.

The outline is broad. The 2022 OTR content outline has 16 tasks and 62 knowledge statements in four domains. In one exam you can move from IEP plans and child development to wound care, physical agent modalities, orthoses and prostheses, wheelchair seating, driving adaptations, infection control, state practice acts and reimbursement. The 2022 practice analysis behind the outline surveyed 2,137 recently certified OTRs whose main settings ranged from pediatric clinics and early intervention (21.4%) and schools (20.6%) to skilled nursing (14.0%) and acute care (13.0%). Your fieldwork probably covered two or three settings. The outline is written for all of them.

Scenario sets ask for three right answers. Each set opens with a practice scene, then asks four related items with six options each, and you select the three best. NBCOT gives credit for each correct option you select, so a partly right answer still earns something, but you need to judge six options rather than four. The format guide shows how a set works.

"Best" answers sit next to plausible ones. Single-response items have three or four options with "only one correct or best answer." In practice, more than one option often describes something a therapist might reasonably do, and the item asks which one fits this client, now.

It's long. You have 4 hours for 180 items, about 80 seconds each, and the appointment runs about 4 hours 45 minutes with check-in and tutorials, according to the handbook. Breaks are allowed, but the clock keeps running.

You can't spot the practice items. Each form includes unscored field-test items that look like the others, so every item deserves full effort.

To see how this breadth will be organized when full prep opens, you can see how the planned OTR prep spreads 1,300 questions across the four domains. Checkout isn't open yet.

How hard the exam is for you: questions to ask yourself

Difficulty is personal. A practical self-check before you book:

1. Which settings did your fieldwork skip? If you never worked in pediatrics or mental health, those parts of the outline need dedicated time.
2. How do you do on application questions under time? Untimed reading feels easier than 80 seconds per item, which is why it helps to rehearse that pace in the 180-question timed mock exam planned for full OTR prep.
3. Have you practiced "select three" items? NBCOT offers two free sample scenario sets on its Foundations page, and its paid Scenario Item Practice Test has ten sets.
4. How long can you study? NBCOT's Prepare page says students report spending 6 weeks studying. If you're working full time or returning after a gap, plan for longer.

Once you know where you stand, the OTR study plan guide turns the four domain weights into a schedule.

A first step for gauging the OTR exam

Start with a baseline. The 20 free OTR practice questions are original single-answer items spread across the four domains, each with an explanation. Twenty questions can't estimate a score, and they don't include scenario sets, so use them to see which kinds of reasoning slow you down. Then build a schedule in the free OTR study planner, and if you expect to study for several months, compare the 30-, 90- and 180-day access periods planned for OTR prep.
