Certified Paraoptometric (CPO) Exam – Practice Test & Study Guide 2025

If you’re currently working in an optometry clinic or looking to break into the vision care industry, becoming a Certified Paraoptometric (CPO) is one of the smartest moves you can make. This nationally recognized credential, offered by the American Optometric Association (AOA), confirms your foundational knowledge in patient care, optical procedures, and clinical operations. It’s an excellent way to boost your credibility with employers, demonstrate your commitment to the profession, and increase your earning potential.

As a paraoptometric, you're a key part of the optometric team — and certification shows you're prepared to handle responsibilities such as performing pre-tests, educating patients, supporting doctors during exams, and assisting with contact lens fittings. Whether you're just starting your journey or have been in the field for a while, the paraoptometric certification gives you a clear edge in today’s competitive healthcare job market.

📘 What Is the Certified Paraoptometric (CPO) Exam?

The Certified Paraoptometric Exam is the first in a tiered series of certifications, specifically designed for individuals who support optometrists in clinical or administrative roles. It’s a written, multiple-choice exam that evaluates your understanding of eye anatomy, medical terminology, vision testing, front desk duties, insurance procedures, and optical math.

To be eligible, you’ll need a high school diploma or GED and at least six months of experience in an eye care setting or completion of a formal training program. The exam is administered at PSI testing centers and must be scheduled during specific testing windows throughout the year. With 100 questions and a time limit of 2 hours, the CPO exam covers a broad but manageable range of material — especially if you study with the right resources.

Passing this exam earns you the official CPO designation, which is valid for three years and can be renewed with continuing education credits.
