CPO Questions and Answers

How many questions are on the CPO exam?

The Certified Paraoptometric (CPO) exam consists of 200 multiple-choice questions. Candidates are given three hours to complete the test. The questions are drawn from the core competency areas defined by the American Optometric Association (AOA) Commission on Paraoptometric Certification, covering clinical and administrative duties performed in optometric practice.

What is the format of the CPO certification exam?

The CPO exam is a computer-based, multiple-choice test administered at Prometric testing centers across the United States. Each question has four answer options with one correct response. The exam is closed-book, and no reference materials or electronic devices are permitted during the testing session. Results are typically available within four to six weeks.

What are the eligibility requirements for the CPO exam?

To sit for the CPO exam, candidates must have a high school diploma or equivalent and at least six months of work experience in an optometric setting. Alternatively, graduates of a paraoptometric education program approved by the AOA may qualify without the work experience requirement. There is no mandatory prerequisite coursework beyond these baseline criteria.

How do I register for the CPO exam?

Registration for the CPO exam is handled through the American Optometric Association Commission on Paraoptometric Certification. Candidates submit an application online at the AOA website, pay the applicable exam fee, and then schedule their testing appointment through Prometric. The exam is offered during designated testing windows throughout the year, so early registration is recommended.

What study materials are recommended for CPO exam preparation?

The AOA recommends the Paraoptometric Resource Manual as the primary study guide for CPO candidates. Additional preparation resources include the AOA online study modules, flashcard sets covering optics and ocular anatomy, and practice exams that mirror the actual test format. Reviewing clinical procedures you perform daily in practice also reinforces key concepts tested on the exam.

How is the CPO exam scored?

The CPO exam uses a scaled scoring method based on the number of correct answers. There is no penalty for guessing, so candidates should answer every question. The minimum passing score is determined through a criterion-referenced standard-setting process, meaning it reflects the level of knowledge required for competent entry-level paraoptometric practice rather than a fixed percentage.

What is the difference between CPO and CPOA certification?

The CPO (Certified Paraoptometric) is the entry-level credential for ophthalmic support staff, while the CPOA (Certified Paraoptometric Assistant) is an advanced certification requiring additional clinical knowledge. The CPOA exam covers more complex topics including advanced ocular disease, diagnostic testing procedures, and contact lens management. Candidates must hold a current CPO before pursuing the CPOA designation.

Can I retake the CPO exam if I do not pass?

Yes, candidates who do not pass the CPO exam may retake it during a subsequent testing window. There is no limit on the number of attempts, but you must submit a new application and pay the full exam fee for each retake. The AOA recommends waiting at least 90 days between attempts to allow adequate time for additional study and preparation.
