The CPOA (Certified Paraoptometric Assistant) exam is the entry-level certification offered by the American Optometric Association (AOA). It is designed for people who are starting their career in an optometric practice. The exam covers preliminary patient testing, patient communication and education, office procedures and administration, basic ophthalmic optics, and general eye care knowledge. Passing the CPOA shows that you have the foundational skills to support an optometrist.
The CPOA exam is a multiple-choice, computer-based test. It uses scaled scoring with a criterion-referenced passing standard. You will receive results broken down by content area so you can clearly see your strengths and where you need improvement. The exam is offered at testing centers nationwide.
Most candidates do well with 2 to 3 months of preparation, spending about 1 hour per day. Since the CPOA focuses on foundational knowledge, you do not need as long as you would for the more advanced CPO exam. If you are already working in an optometric office, many of the topics will feel familiar. Opterio's adaptive platform adjusts to your current level and helps you use your study time efficiently.
Opterio gives you AI-powered adaptive practice that focuses on your weak areas, a question bank covering all CPOA content areas, clear explanations for every question, spaced repetition to help you remember what you learn, progress tracking by content area, and the flexibility to study on web or mobile. It is the most efficient way to prepare for your CPOA certification.
