ExploreAbout this exam
The Certified Orthoptist credential is awarded through the American Orthoptic Council (AOC), which describes itself as the certifying body for orthoptists and the organization that sets certification and recertification standards of orthoptic excellence. Orthoptists are described by the AOC as a small profession and a critical part of the eye care team, working alongside ophthalmologists in the evaluation and management of binocular vision and eye movement disorders. The credential is intended for graduates of AOC-accredited orthoptic programs who complete the board examinations, and it is maintained through continuing education; the AOC separately provides guidance to the American Association of Certified Orthoptists (AACO), the membership organization that hosts CE opportunities and advises on clinical practice. Because the AOC frames its mission around four activities, candidates should expect assessment across orthoptic education and clinical/education competencies, continuing education and recertification standards, binocular vision and ocular motility, and scope of practice and professional standards. Preparation should center on the AOC's published syllabus and core competency materials, the Journal of Binocular Vision and Ocular Motility, and the educational resources the Council lists for students and accredited programs.

What you'll study
About AOC C.O. preparation
Who actually administers the Certified Orthoptist credential?
The American Orthoptic Council states that it is the certifying body for orthoptists and that it sets certification and recertification standards of orthoptic excellence. The AACO is a separate membership organization for certified orthoptists; the AOC provides it guidance, and the two work together to advance the practice of orthoptics.
What content areas does the exam cover?
The AOC organizes its work around setting education and continuing education standards, verifying clinical and education competencies, supporting ongoing education growth, and guiding the future of orthoptics. Build study around those pillars plus binocular vision and ocular motility, scope of practice, and professional standards, using the AOC syllabus and core competency publications as your outline.
How many questions are on the exam and how long does it take?
The AOC public pages do not publish item counts, time limits, or a passing score, so treat any specific number you hear as unverified. Confirm the current format, timing, and scoring directly with the AOC before you plan your test-day pacing or set a target score.
What does it cost and how long is the certification valid?
Fees and validity periods are not stated on the AOC home page, so they cannot be quoted reliably here. Because recertification standards are one of the Council's core functions, ask the AOC directly about the current fee schedule, the length of the certification cycle, and what recertification requires.
Is there a retake policy if I do not pass?
Retake rules, waiting periods, and any limits on attempts are not described in the AOC material available here. Contact the AOC home office in Madison, Wisconsin, before your exam date so you understand the options and any deadlines that would apply if you need to sit again.
How should I sequence my studying?
Start with the AOC syllabus and core competency publications to map the tested domains, then study binocular vision and ocular motility in depth since sensory and motor testing underpins clinical practice. Layer in scope of practice and professional standards, and finish with continuing education and recertification rules, which are frequently overlooked.
What are the most common ways candidates lose points?
Two predictable gaps: weak handling of incomitance and measurement technique in motility cases, and neglect of the professional-practice domain, including scope of practice and recertification requirements. Candidates also underprepare for the education and competency standards the AOC emphasizes, treating them as background rather than testable content.
Where can I find continuing education after I am certified?
The AOC lists ways to earn CE and accepts requests to approve CE for meetings, and the AACO hosts CE opportunities for its members. The Journal of Binocular Vision and Ocular Motility and the AOC educational resources are useful for both exam preparation and ongoing credit.
Can international candidates apply?
Yes. The AOC site references new International Candidate requirements and points international applicants to dedicated information. Requirements differ from the standard pathway, so read that section carefully and confirm your eligibility and documentation with the Council before applying.
How can an employer verify that someone is certified?
The AOC provides a verification resource for the public and employers, alongside guidance on hiring orthoptists. Employers should use that verification path rather than relying on a CV claim, and candidates should make sure their certification status is current before representing themselves as certified.
