How many parts of the National Board exams must be passed for licensure?

To become licensed as an optometrist, it is required to pass three distinct parts of the National Board of Examiners in Optometry (NBEO) exams. These three parts encompass the essential skills and knowledge necessary for effective practice in the field of optometry. After successfully completing these parts, candidates must also pass a state exam specific to the state they intend to practice in, which adds an additional layer of assessment tailored to state regulations and laws governing optometric practice. This structure ensures that candidates are well-rounded in both national standards and localized legal requirements, ultimately protecting public health and safety.
