About this exam
The National Board of Examiners in Optometry (NBEO) Part I Applied Basic Science Examination is a foundational examination in the U.S. optometry licensure sequence. It assesses whether candidates can apply basic biomedical and vision-science knowledge relevant to optometric care; it is not an admissions test for optometry school. Candidates commonly take Part I after completing substantial basic-science coursework in an optometry program. Individual state boards set their own licensure requirements, so passing this examination is one part of a broader process.
NBEO Part I review commonly includes ocular anatomy and physiology, general anatomy relevant to optometry, and ocular embryology and development, alongside other foundational sciences described in the current exam blueprint. The challenge is connecting concepts across systems, not simply memorizing isolated terms. Start with the official NBEO candidate materials to confirm the current content outline, exam structure, and policies. Then use active recall, spaced review, and timed multiple-choice practice to find gaps and strengthen understanding before test day.
How to prepare for the NBEO Part I Applied Basic Science Examination
- Map your study plan to the current NBEO content outline. Review ocular anatomy, ocular physiology, embryology and development, and general anatomy relevant to optometry, then allocate extra time to weaker areas.
- Use timed multiple-choice practice to build pacing and application skills. After each set, explain why the correct answer fits and why your chosen distractors do not; revisit missed concepts rather than memorizing answer patterns.
- Check the NBEO candidate guide and official exam materials for current eligibility, format, policies, and content updates. Schedule spaced review sessions and include cumulative checks so earlier topics stay fresh.
FAQ
Who is eligible to take the NBEO Part I exam?
Candidates are generally students in optometry programs who have reached the point in their education when they are eligible to sit for the examination. Eligibility and registration requirements can depend on current NBEO rules and school procedures, so confirm details with your program and the official NBEO materials.
What is the format of the NBEO Part I Applied Basic Science Examination?
Part I is a standardized examination using multiple-choice questions to assess applied basic-science knowledge. Consult the current NBEO candidate guide for the latest details on exam timing, delivery, and structure, as these policies can change.
What subjects should I study for NBEO Part I?
Use the current NBEO content outline as your guide. Key areas for review include ocular anatomy and physiology, ocular embryology and development, and general anatomy relevant to optometry, as well as the other foundational-science topics listed in the official blueprint.
