The ABO (American Board of Opticianry) exam, officially known as NOCE (National Opticianry Competency Exam), is the certification exam for dispensing opticians. It consists of 125 multiple-choice questions covering 6 domains: Ophthalmic Optics, Ocular Anatomy and Refraction, Ophthalmic Products, Instrumentation, Dispensing Procedures, and Laws & Regulations. The exam tests both theoretical knowledge and practical skills needed to fit and dispense eyeglasses and contact lenses.
The ABO exam requires a minimum score of 70% to pass. The exam uses scaled scoring, meaning your raw score is converted to a scaled score between 0-100. You'll receive your results immediately after completing the computer-based exam, along with a breakdown of your performance in each domain.
Most successful candidates study for 2-3 months, dedicating 1-2 hours daily to exam preparation. This timeline allows you to thoroughly cover all six exam domains, complete practice questions, and review weak areas. If you have prior optical experience, you may need less time.
