CRA Certification

What the Certified Retinal Angiographer Credential Actually Is

The Certified Retinal Angiographer (CRA) credential is a professional certification offered by the Ophthalmic Photographers' Society (OPS) Board of Certification. It recognizes competence in the specialized imaging of the retina, with particular emphasis on fluorescein angiography, fundus photography, and the supporting skills that make those procedures safe and diagnostically useful. If you are searching for a plain-language definition first, our explainers on what CRA certification is and what CRA stands for cover the basics; this article goes deeper into the structure of the credential itself.

Two features set this credential apart from many allied-health certifications. First, it combines a written examination with a documented, applicant-produced imaging portfolio, so you must show real images, not just answer questions about them. Second, its content outline is not a loose study curriculum. The ten weighted content areas in the current CRA Program Guide (version 15.1, effective June 2026) are the official exam objectives, drawn from the 2017 job analysis. What is weighted on that outline is what is tested.

Who Pursues It and Who Hires for It

Retinal angiographers typically work in settings where retinal disease is diagnosed and monitored. That includes retina specialty practices, comprehensive ophthalmology groups, university eye institutes, hospital-based eye departments, and clinical research programs that rely on standardized retinal imaging. Employers in these settings value the credential as an independent signal that a photographer can produce consistent, interpretable angiograms and manage the patient safely during dye injection.

The credential also fits a range of career entry points. Many candidates are ophthalmic technicians or photographers who have been performing angiography under supervision and want formal recognition. Others are working toward the Provisional CRA status described below while they complete the experience requirement. For a closer look at the employment side, see our overview of CRA jobs, and for compensation context, the CRA salary guide. If you are weighing the investment, the ROI analysis on whether the CRA is worth it walks through the trade-offs.

Eligibility and the Imaging Portfolio

Before you can sit for the written exam, the OPS Board of Certification expects three things to be in order. Your application and supporting documents are reviewed first; the exam follows approval.

• An accepted imaging portfolio. This is a body of images you produced yourself, submitted for review as part of the application.
• Verified experience. An employing physician or institution verifies two years of retinal-angiography experience.
• Current CPR. This includes a current in-person skills assessment for initial certification.

Some education or professional credentials can substitute for up to one year of the experience requirement. Candidates who still need to complete the work-experience requirement may be eligible for Provisional CRA, a distinct status rather than a shortcut around the standard path. No mandatory OPS preparation course and no universal training-hour total has been verified, so there is no single prescribed training track you must complete. For the full eligibility walk-through, read our CRA requirements guide, and for the education side, see CRA training.

The Exam Format: 175 Questions in Two Hours

The written exam is delivered by computer at Prometric test centers. No current remote or adaptive delivery option has been verified, so plan around a physical testing location. Here is what to expect:

Two hours for 175 questions works out to well under a minute per item, so pacing matters. There is no penalty beyond the lack of credit: incorrect and blank answers both earn nothing, which means you should answer every question rather than leave any blank. The "best answer" wording is worth internalizing. In clinical imaging, several choices may be partially defensible, and the exam rewards selecting the most appropriate one.

A note on older materials: some OPS pages still describe 2.5 hours for the written exam and a separate performance assessment of two to four hours. Those details conflict with the June 2026 Program Guide, which describes a two-hour written exam following portfolio approval, and they do not override it. Treat the current guide as your controlling document and confirm specifics with OPS before you register. For a candid look at the challenge, see how hard the CRA exam is.

Where the Points Are: The Ten Weighted Domains

The exam blueprint has ten content areas whose published weights sum to 100%. Fluorescein Angiography is the largest at 25%, followed by Fundus Photography at 23%, together making up 48% of the exam. Here is the full breakdown:

Our companion piece, the complete guide to all 10 CRA content areas, unpacks each in detail. Below are the highest-leverage areas and what candidates should be ready for.

The smaller domains should not be dismissed. General Photography (10%) tests the optical and exposure principles underlying all your imaging. Patient Management and Patient/Operator Safety (6%) and Pharmacology (5%) are where dye reactions, contraindications, and emergency awareness come in; they are compact but practical, and the questions tend to be scenario-driven. Monochromatic Imaging and Fundus Autofluorescence (5%), Data and Image Management (4%), ICG Angiography (3%), and Other Imaging Technology (3%) each contribute modestly, but together they account for 15% of the exam.

How Scoring and Results Work

The CRA uses a criterion-referenced standard set through a Modified Angoff V competency method, with results reported on a scaled basis. In practice this means you are measured against a defined competency standard rather than against other test takers. No current numeric cut score is publicly verified, so be wary of any source that quotes a specific percentage you must hit. Our page on the CRA passing score explains what is and is not known.

• If you pass: you receive a pass notice without a numeric score.
• If you do not pass: you receive a scaled score and a diagnostic content-area report, which is a useful map for a retake.
• Timing: initial score reports are provisional pending a 72-hour statistical verification, and the Program Guide notes that reporting delays can occur during exam-development cycles.

On pass rates, no current 2026 figure is publicly verified. OPS historical reports show 537 passes among 857 tested (63%) from April 1997 through July 2018, but that is a long historical span and not a current first-attempt rate. The 2013 to 2018 annual reports also give small-sample summary counts, such as 9 passes in 14 written administrations in 2018, which are too small and internally inconsistent in places to treat as a reliable predictor. Read our breakdown of the CRA pass rate data for the full context, and treat any single number with caution.

Fees, Retests, and Registration Mechanics

A few mechanics are worth noting. The $50 non-refundable application component is already included in the initial fee, not charged on top of it. The non-member price bundles a one-year OPS membership, so the real difference between the two tiers is smaller than the sticker gap suggests, and joining first may be the simpler route if you want membership benefits anyway. If you renew by retesting instead of earning continuing education credits, you pay the examination fee with no additional recertification fee. For the complete financial picture, including the costs surrounding the exam, see the CRA certification cost breakdown.

For scheduling, your path runs through the application and portfolio review first, then Prometric appointment booking once you are approved. Our CRA exam dates guide covers timing and deadlines. Accommodations are available through the published OPS process, so request them early if you need them.

Sequencing Your Preparation Around the Weights

This is the one place for scheduling advice, and it is tied directly to the blueprint. The logic is simple: study the foundation first, then the heavy imaging domains, then the compact specialty areas, and finish with timed practice. A sample eight-week arrangement:

Pairing Domain 7 with Safety and Pharmacology is deliberate: exam questions often blend them in a single patient scenario. Practice under realistic conditions using the CRA practice test, and for a fuller roadmap, read the CRA study guide. When you want a compact review near exam day, the CRA cheat sheet condenses must-know facts, and you can find additional practice questions on the main site.

Keeping the Credential: The Three-Year Cycle

Certification is not permanent. Recertification cycles run three years, starting January 1 of the year after you earn the credential. You have two routes to renew:

1. Continuing education. Earn 15 CECs during the cycle, including at least five from official OPS or OPS BOC pre-approved courses and workshops. Teaching, eligible non-OPS-approved attendance, and publication categories are each capped at ten credits, and eligible non-OPS attendance earns 0.5 CEC per hour.
2. Retest. Pass the examination again by the end of year three, paying the exam fee with no extra recertification charge.

Renewal is $100 for members and $225 for non-members. One detail to watch: live OPS renewal pages refer to current CPR and accept specified American Heart Association or American Red Cross online refresher testing, while the June 2026 Program Guide's renewal checklist omits CPR. That discrepancy is real and unresolved in the public record, so confirm the current expectation with OPS rather than assuming CPR is no longer required. Do not confuse this with initial certification, which requires an in-person CPR skills assessment.
