The National Board of Examiners in Optometry (NBEO) administers the rigorous, three-part examination sequence required for optometry licensure in the United States and several other jurisdictions.

This exam sequence is designed exclusively for students and graduates of accredited schools and colleges of optometry.

Its primary purpose is to assess whether candidates possess the essential knowledge, clinical skills, and judgment necessary to practice optometry safely and competently.

Successfully passing all parts of the NBEO is a critical milestone, representing the transition from student to licensed healthcare professional.

What the Course Entails and Exam Details

NBEO preparation does not involve a traditional single "course" but rather a comprehensive synthesis of four years of optometric education, often supplemented by targeted NBEO practice tests.

The exam series, and the corresponding preparation, is structured into three distinct parts, each covering essential pillars of optometric practice.

Part I, Applied Basic Science (ABS), focuses foundational knowledge, covering topics such as human anatomy and physiology, biochemistry, genetics, microbiology, pathology, optics (geometric, physical, and ophthalmic), visual science, and pharmacology.

Part II, Patient Assessment and Management (PAM), transitions into clinical application, requiring candidates to synthesize clinical data to make differential diagnoses and formulate management plans across a wide range of ocular and systemic conditions.

Part III, Clinical Skills (CSE), is a hands-on, practical examination assessing a candidate’s ability to perform essential clinical techniques (e.g., binocular indirect ophthalmoscopy, biomicroscopy, and tonometry) with high proficiency.

Preparation therefore demands a deep dive into didactic material, extensive review of clinical case studies, and hands-on practice of technical skills.

 What to Expect in the Final Exam

The full NBEO examination process involves multiple formats spread across its three parts.

Parts I (Applied Basic Science) and Part II (Patient Assessment and Management) are computer-based examinations comprised primarily of multiple-choice questions and clinical case scenarios.

Part I (ABS) is typically the longest, often a two-day event consisting of several hundred items.

Part II (PAM) is generally shorter than Part I but focuses heavily on high-level clinical decision-making.

Part III (Clinical Skills) is significantly different, requiring candidates to travel to the dedicated NBEO National Center for Clinical Skills Assessment (NCCSA) in Charlotte, North Carolina.

During Part III, candidates perform specific clinical techniques on standardized patients and are evaluated by examiners on their technical proficiency, interpersonal skills, and professionalism.

The NBEO utilizes a scaled scoring system (ranging from 100 to 900 for computer-based parts), and the specific passing score is set by the Board to reflect the minimum standard of competence required for entry-level practice.

 How to Study and Exam Centers

Effective preparation for the NBEO requires an integrated strategy that balances foundational review with active test-taking practice.

A primary strategy is to utilize comprehensive NBEO practice tests and review courses, which simulate the actual exam format and help identify specific knowledge gaps.

Establish a structured study schedule that allocates dedicated time for reviewing key didactic concepts in anatomy, physiology, and pharmacology, especially for Part I.

For Part II (PAM), practice working through numerous clinical case studies and differential diagnosis trees to refine clinical judgment and management planning.

For Part III (Clinical Skills), hands-on practice is irreplaceable; students must repeatedly perform all required skills in a mock exam setting until they are efficient and confident.

Regarding locations, the computer-based Part I and Part II exams are administered at Pearson VUE testing centers throughout the United States.

Conversely, the practical Part III examination is administered exclusively at a single location: the NBEO National Center for Clinical Skills Assessment (NCCSA) in Charlotte, North Carolina.

Job Opportunities from the Course

Successfully navigating the NBEO examination process is the master key that unlocks nearly all professional opportunities within the field of optometry.

Passing the NBEO is the foundational requirement for state licensure, enabling you to practice as a licensed Optometric Physician or Doctor of Optometry (OD).

This credential opens doors to a wide array of career paths and employment models:

• Private Practice Optometrist: Operating your own clinic or practice.
• Associateship: Joining an established private practice group.
• Corporate Optometry: Practicing in a setting affiliated with major optical retailers.
• Academia: Pursuing roles in teaching or research at schools and colleges of optometry.
• Hospitals and Medical Centers: Working within multidisciplinary healthcare settings, such as Veteran Affairs (VA) hospitals.
• Specialty Practice: Focusing on specific areas like sports vision, pediatric optometry, low vision rehabilitation, or contact lenses.
• Industry Roles: Working as a consultant or clinical trial researcher for contact lens or pharmaceutical companies.
