American Board of Opticianry (ABO) Practice Test 2026 - Free ABO Practice Questions and Study Guide

The primary purpose of the ABO Exam is to assess the competency of opticians in their knowledge and skills. This examination is designed to ensure that opticians possess the necessary understanding of optics, vision science, and optical fitting, as well as the ability to apply this knowledge effectively in a professional setting. By evaluating an optician's knowledge and practical skills, the ABO Exam helps maintain a standard of care and practice within the optical industry, ultimately ensuring that patients receive safe and effective eye care services.

In contrast, while training new opticians in practical skills is important for their development, that task is usually addressed through educational programs rather than an exam. The provision of continuing education credits serves to enhance the knowledge of practicing opticians but does not define the primary purpose of the exam itself. Additionally, evaluating customer satisfaction in optical services is outside the scope of what the ABO Exam measures, as it focuses specifically on the knowledge base and competencies of the opticians.
