Why Get Paraoptometric Certified?
CPO and CPOA credentials set you apart in the growing field of optometric care and open doors that on-the-job experience alone cannot.
Career Advancement
Certification qualifies you for higher-responsibility roles in an optometry practice. Many ODs prefer or require certified staff for clinical testing, pretesting, and patient education duties. It is the clearest path from entry-level to senior paraoptometric.
Salary Boost
Certified paraoptometrics typically earn more than their uncertified peers. Practices recognize the investment you have made in professional development and reward it with higher starting pay and faster raises.
Professional Recognition
The CPO and CPOA designations are nationally recognized credentials administered by the Commission on Paraoptometric Certification. They demonstrate verified competence in optometric clinical skills and patient care to employers anywhere in the country.
Patient Trust
Patients feel more confident when they know the staff assisting their eye exam holds a recognized certification. Your credentials signal professionalism and competence, strengthening the patient-practice relationship from the first interaction.
The Certification Landscape
Unlike opticianry, which has dozens of formal college programs, the paraoptometric field has fewer dedicated training schools. This is actually a strength of the profession: the barrier to entry is lower, and there are multiple pathways to certification.
Many paraoptometrics enter the field by getting hired at an optometry office with no prior experience, learning clinical and administrative skills on the job, and then sitting for the CPO exam once they accumulate the required hours. Others choose a formal program at a technical college or community college that includes structured coursework and clinical rotations.
The AOA itself offers a robust set of self-study materials -- from the Skill Builder series to dedicated review courses on EyeLearn -- designed specifically for people preparing through the work-experience pathway. Combined with third-party practice tools like Opterio, self-study candidates have access to everything they need to pass the CPO or CPOA exam without enrolling in a formal program.
The resources below include both formal programs and self-study materials. Browse them to find the combination that fits your schedule, budget, and learning style.

Accumulate Hours
Work for at least 6 months (1,040 hours) under a licensed optometrist. This satisfies the CPC experience requirement and gives you hands-on clinical knowledge that no textbook can replace.
Study and Practice
Use AOA review materials, the Skill Builder series, and Opterio's CPO practice questions to prepare. Spaced repetition helps you retain everything you learn on the job and in your study sessions.

Apply through the CPC, schedule your exam, and earn your Certified Paraoptometric credential. From there, you can pursue CPOA and eventually CPOT as you advance in your career.

Frequently Asked Questions
What is the difference between CPO and CPOA certification?
CPO (Certified Paraoptometric) is the entry-level certification for paraoptometric assistants. It covers fundamental clinical and administrative skills used in an optometry practice. CPOA (Certified Paraoptometric Assistant) is the next level up, requiring deeper knowledge of ophthalmic procedures, patient care, and clinical testing. Both are administered by the Commission on Paraoptometric Certification (CPC) through the AOA. You must earn CPO before pursuing CPOA.
Do I need a formal program to sit for the CPO exam?
No. The CPC offers multiple eligibility pathways. You can qualify with a combination of on-the-job experience (typically 6 months or 1,040 hours in an optometric setting) and self-study. Formal programs from CPC-approved schools can substitute for part or all of the experience requirement. Many successful paraoptometrics prepare entirely through work experience plus AOA study resources and third-party test prep tools like Opterio.
How long does it take to become a Certified Paraoptometric?
The timeline varies by pathway. If you attend a formal program, most take 6 to 12 months. If you go the work-experience route, you need at least 6 months (1,040 hours) of employment in an optometric setting before you are eligible. Many people study for the CPO exam for 2 to 4 months while working. Overall, most candidates earn their CPO within 6 to 18 months of starting in the field.
Can I use Opterio to prepare for both CPO and CPOA exams?
Yes. Opterio offers dedicated practice question sets for both CPO and CPOA exams. Each question includes a detailed AI-generated explanation so you understand the reasoning behind each answer. The spaced repetition algorithm adapts to your performance, focusing review on your weak areas. You can start with CPO practice and transition to CPOA content when you are ready to advance.
