How Hard Is the NBEO Part 1? Pass Rates and Trends

The national first-time pass rate has fallen from about 77% in 2015 to roughly 62-67% in recent years. The exam is now widely described as harder than prep banks, with form-to-form variance and conceptual optics items that reward deep understanding. The exam is very passable with deliberate, active preparation, but the old advice that it is easy to pass is outdated. Let's unpack what that actually means for your study plan.

The question every optometry student asks is some version of: how hard is this really? The honest answer is that NBEO Part 1 is hard enough to fail if you underestimate it, and passable if you prepare deliberately. Understanding the national trends, the form-to-form variance, and the recent shift in student reports can help you set the right expectations and build an effective plan.

The National Pass-Rate Story

The national first-time pass rate for NBEO Part 1 has declined over the past decade. From about 76.9% in 2015, it fell to roughly 62-67% in recent years. Reported figures cluster around 62-67% for several recent cycles. The March sitting (targeted prepared third-years) consistently runs higher than the August sitting, which is understood as the retake administration.

Ultimate pass rates by graduating class (across all three parts) are higher, in the 80s, which means most students eventually pass. The story is not that optometry students cannot become licensed. The story is that first-attempt failure on Part 1 is now common, affecting roughly one in three recent first-time takers.

Why the Pass Rate Fell

No single official cause explains the decline. The current one-day, 370-item computer-based format launched in March 2017, so the format change is not recent. The drop from 2020-21 to 2021-22 coincided with COVID-disrupted cohorts, which likely played a role. Other factors may include the condition-based blueprint, the conceptual shift in optics, and changes in how students prepare. Any single-cause explanation is unverifiable.

What matters for you is not why the rate fell in the aggregate. What matters is that the exam now filters more strictly, and preparation must be active rather than passive.

Harder Than Prep Banks

A notable shift in student reports from 2025-2026 is that the real exam is now described as harder than the major prep banks. Older advice sometimes claimed that timed bank mocks were harder than boards. Current student sentiment has flipped. Many recent test-takers warn each other not to trust that older advice.

The reasons students give include:

• The wording is more convoluted and riddle-like.
• Optics items are more conceptual and less formulaic.
• Form-to-form variance is large; one form may be heavy in systemic disease while another is heavy in micro/histology.
• The 20 invisible pretest items can make the exam feel weird and unpredictable.

This does not mean prep banks are useless. It means you should calibrate against recent sentiment, use multiple resources, and focus on understanding rather than pattern recognition.

Form-to-Form Variance

Form variance is one of the most consistent themes in student reports. Two students testing in the same window may have very different experiences. One may see a form heavy in systemic health questions; another may see a form heavy in uveitis or anatomy. This is why narrow preparation is risky. You cannot predict which specific topics will dominate your form, so you need broad coverage across the blueprint.

The Cross-Profession Comparison

At a national optometry meeting, a presentation found that NBEO Part 1 had the lowest first-time pass rate among comparable health-profession board exams in nearly every year studied. This is not a reason to panic, but it is a reason to take the exam seriously. The exam is designed to protect the public by ensuring that licensed optometrists have a strong foundation in biomedical and visual science.

What This Means for Your Preparation

The pass-rate decline and harder-than-banks shift mean that the following strategies are now more important than ever:

• Use active recall instead of passive reading.
• Prioritize optics and conceptual understanding.
• Build broad coverage across the blueprint rather than betting on a narrow topic list.
• Train full-length stamina with back-to-back 185-question sessions.
• Use multiple resources, including the official Practice Items Databank if budget allows.
• Take the exam seriously; do not treat it as a practice run.

The Emotional Side

The difficulty of NBEO Part 1 is not just intellectual. It is emotional and financial. The exam fee is $1,490, retakes are limited, and a delayed pass can delay licensure and job starts. The stakes are real, but the exam is still passable. The students who pass are the ones who prepare deliberately, manage their energy, and stay consistent over months. We've been through this with thousands of students, and the pattern is always the same: the ones who treat it like a serious challenge, not a formality, are the ones who walk away with a pass.

How to Stay Calm and Focused Despite the Difficulty

The pass-rate decline can be scary, but it is not a prediction of your individual outcome. Your preparation is within your control. Here is how to keep the national statistics from becoming self-defeating anxiety.

Focus on controllable factors. You cannot control the national pass rate, the form difficulty, or how other students perform. You can control your daily question target, your sleep, your optics study, and your mock schedule. Direct your attention to those inputs.

Use the pass rate as motivation, not fear. A lower pass rate means the exam rewards serious preparation. Students who study actively, take the exam seriously, and build stamina have a strong chance of passing. The exam is not random; it tests the same foundational competencies every time.

Ignore post-exam forums. After the exam, online forums fill with anxiety and answer comparing. This behavior increases stress without improving your score. Once the exam is over, your score is determined. Focus on recovery, not speculation.

Trust your trend. A rising mock score trend is a better predictor of your readiness than any single number or any national statistic. If your last two mocks show improvement and you are scoring in the likely-pass range, you are prepared.

Remember the long game. Even if you do not pass on the first attempt, most students eventually pass. The exam is a milestone, not a measure of your worth as a future optometrist. Keep the perspective that licensure is the goal, not a single test date.

Quick Review Checklist for Managing Difficulty

Use this checklist to make sure the exam's difficulty is informing your preparation without derailing your mindset.

• You know the national first-time pass rate is roughly 62-67% in recent years.
• You understand that recent forms are described as harder than prep banks.
• You are preparing for form-to-form variance with broad blueprint coverage.
• You focus on controllable inputs: questions, optics, stamina, and sleep.
• You do not treat the exam as a practice run or formality.
• You use rising mock scores as your primary readiness signal.
• You avoid post-exam answer comparing and forum anxiety.
• You remember that most students eventually pass all required NBEO parts.

The difficulty is real, but so is your ability to prepare for it.

How to Talk to Family and Friends About the Exam

The people around you may not understand why NBEO Part 1 feels so stressful. Explaining it well can help you get the support you need.

Set expectations early. Let family and friends know that you will be less available in the months before the exam. Ask for their patience and support rather than apologizing repeatedly. Most people will respect a clear boundary if you communicate it upfront.

Explain the stakes simply. You do not need to detail the entire blueprint. Say that it is a national licensing exam with a significant first-attempt failure rate, and that passing keeps you on track for graduation and your career. This helps others understand why you are studying so much.

Ask for specific help. Instead of saying you are stressed, ask for concrete support: a quiet study space, help with chores, or a walk once a week. Specific requests are easier for others to fulfill than vague requests for support.

Protect your boundaries. It is okay to decline social events during heavy study weeks. You can reconnect after the exam. Guilt about saying no is normal, but temporary boundaries are part of any high-stakes preparation.

Share the good news when it comes. After the exam, tell the people who supported you how it went. Celebrating the milestone together reinforces the social support system that helped you through it.

What This Means for You

The falling national pass rate does not mean you are unlikely to pass. It means the exam now requires more deliberate preparation than it may have in the past. If you take the exam seriously, prepare with active recall, prioritize Optics, and train full-length stamina, you are putting yourself in the best possible position. Your individual outcome depends on your effort and strategy, not on the aggregate statistics. Use the difficulty as a reason to prepare thoroughly, not as a reason to doubt yourself.

Key Terms to Remember

• National first-time pass rate: The percentage of first-time candidates who pass NBEO Part 1, recently reported in the 62-67% range.
• Criterion-referenced: An exam scoring approach where the passing standard is based on required competence, not on how other candidates perform.
• Form difficulty: Variation in how hard individual exam forms are, addressed by equating so that scores are comparable.
• Form variance: Differences in topic emphasis across exam forms, which makes broad blueprint coverage important.
• Pass-rate decline: The observed decrease in NBEO Part 1 first-time pass rates over the past decade.
• Readiness signal: A trend in mock scores that indicates whether your preparation is on track, more reliable than a single score.

What to Do If Your School's Pass Rate Differs

School-reported pass rates sometimes look very different from the national rate. A school with a strong pass rate may have a more rigorous curriculum, better advising, or a student culture that emphasizes early preparation. A school with a lower rate may have faced a single difficult cohort, changes in leadership, or less structured board support. The national rate is a better benchmark for individual preparation because it includes many programs and many years of data.

If your school rate is lower than the national average, do not panic. Focus on the variables you can control: your own study hours, your question volume, your optics mastery, and your mock performance. Use school resources where they are helpful, but do not assume they are sufficient. Supplement with a comprehensive platform that explains the why behind every answer and lets you drill weak areas until they become strengths.

If your school rate is higher than the national average, avoid complacency. A strong school average does not guarantee an individual pass. Students at high-performing schools still fail when they under-prepare, especially in Optics. Use the school culture as momentum, not as a substitute for your own daily work. The goal is not to beat the school average; it is to pass on your first attempt with a score that supports your residency and licensure goals.

NBEO Part 1 is challenging but passable; the national first-time pass rate is around 62-67%, and recent forms are described as harder than prep banks. The key is not to panic — it's to prepare deliberately, focus on what you can control, and trust the process.
