Advanced Certification Exams
In the rapidly changing field of vision care, more and more knowledge and skills are required of practitioners. ABO and NCLE Advanced Certifications focus specifically on the advanced level knowledge and skills needed for ophthalmic dispensing, that is providing spectacle, contact lens, and refraction services.
The Advanced Certification designations, ABOC-AC and NCLE-AC, are earned only after a practitioner has attained several years experience, completes a prescribed curriculum of advanced education, and achieves a passing score on the rigorous examinations, or are part of a State Licensing Board mandating the passing of the ABO and/or NCLE Advanced Examination(s). Test specifications are posted on this site. Please review the Advanced Examination Handbook for more information.
Professionals with advanced certification credential are equipped to work in a variety of practice settings, such as: independent opticians, ophthalmology practices, university hospitals, commercial offices, HMO/managed care offices, optometric offices, large clinics, optical product manufacturers. In short, Advanced Certification equips you in all settings which provide eyeglasses and contact lens services to clients.
From administration to administration, the passing percentages for both the ABO and the NCLE Advanced exams change. For the year 2020, the ABO Advanced Examination had a 40.0% pass rate; the NCLE Advanced Examination had a 44.4% pass rate.

Update as of May 25, 2021: PLEASE READ THIS IMPORTANT UPDATE REGARDING THE PROMETRIC MASK MANDATE POLICY
In some states, executive orders prohibit government agencies and institutions of higher education, respectively, and their officials from mandating face coverings or restricting activities in response to the COVID-19 disaster.
The mandates apply to those state’s universities, but not to private companies. Prometric’s position is to keep the mask requirement, where allowed, to maintain standardization and safety measures across our network as much as possible. As a private company, Prometric will continue to require everyone who comes to one of our global testing centers (that are not connected with state government agencies) to wear an approved face covering for the duration of their time at the location. Individuals not in compliance with this policy will not be allowed to sit for their scheduled appointment. We will also continue to maintain social distancing protocols in common areas, where barriers are not provided.
