What Is CRA Certification?

What the Certified Retinal Angiographer Credential Is

CRA certification is a professional credential for ophthalmic imaging specialists who perform retinal angiography, most notably fluorescein angiography and indocyanine green (ICG) angiography, alongside high-quality fundus photography and related retinal imaging. The acronym stands for Certified Retinal Angiographer, and in this article it refers only to that ophthalmic credential. If you have seen "CRA" attached to other fields, those are separate certifications with unrelated requirements. For a quick orientation on the acronym itself, see our explainer on what CRA stands for.

What distinguishes this credential from a general photography or technician certificate is its focus on a hands-on clinical skill set. A retinal angiographer injects or coordinates the injection of a dye, times image capture to the circulation of that dye through the retinal and choroidal vessels, and produces a diagnostic image series that retina specialists use to detect leakage, ischemia, neovascularization, and other disease signs. The credential tells an employer that the holder has been vetted on both knowledge and demonstrated imaging ability.

Who Issues It and Why It Matters to Employers

The credential is administered by the Board of Certification (BOC) of the Ophthalmic Photographers' Society. OPS is the professional body for ophthalmic photographers and imaging specialists, and its certification program is built around the discipline's own practice. The exam content is tied to a job analysis (2017) and the ten weighted areas listed below are official exam objectives, not optional study suggestions.

Employers who typically value the credential include retina practices, hospital eye departments, academic medical centers, and ophthalmology groups with dedicated imaging suites. In these settings, angiography is not a task assigned casually. A physician relies on the quality of the image series to make treatment decisions, so a recognized credential helps managers screen applicants.

Exam Format: What Test Day Looks Like

The written examination is delivered by computer at Prometric test centers. The structure is straightforward but demanding in pace:

• 175 multiple-choice questions, each with four answer choices and one correct or best answer.
• Two-hour time limit, which works out to well under a minute per question on average.
• Closed book. Outside references, personal calculators, and electronics are prohibited. Scratch paper and a pencil are supplied.
• Valid government photo ID is required at check-in.
• No special guessing penalty. Incorrect and blank answers simply earn no credit, so answer every item.

OPS does not separately disclose how many questions are scored versus unscored, so you should treat every question as if it counts. No current remote or adaptive delivery option is verified; plan on a physical test center. Accommodations are available through the published OPS process, and requests should be made well ahead of your desired date.

Because the test is a time-boxed set of four-option questions, question style matters. Expect clinical-scenario items that describe an angiographic image or a patient situation and ask for the best next step, the likely diagnosis, the correct filter or timing, or the appropriate response to a reaction. Our difficulty guide breaks down which item types candidates find hardest.

The Ten Weighted Content Areas

The exam blueprint is divided into ten content areas whose published weights sum to 100%. Understanding the weighting is the single most useful planning tool you have. The full detail lives in our complete guide to all ten content areas; here is the overview.

The smaller areas should not be dismissed. Pharmacology (5%) and Patient Management and Patient/Operator Safety (6%) are where dye reactions, contraindications, and emergency response live, and a candidate who can describe what to do when a patient becomes ill during an injection is demonstrating exactly the competence the credential exists to certify. Monochromatic Imaging and Fundus Autofluorescence (5%), ICG Angiography (3%), and Other Imaging Technology (3%) round out the modality coverage, while Data and Image Management (4%) addresses storage, labeling, and handling of patient images.

Eligibility, the Portfolio, and Provisional Status

Unlike many credentials where you simply register and sit the exam, CRA certification requires you to qualify first. The core eligibility elements are:

1. An accepted applicant-produced imaging portfolio. You submit images you personally produced, which are reviewed before you are cleared to test.
2. Verified experience. Your employing physician or institution verifies two years of retinal-angiography experience.
3. Current CPR, including a current in-person skills assessment.

Certain specified education or professional credentials can substitute for up to one year of the experience requirement. Candidates who are still working toward the experience requirement may fall under Provisional CRA, a distinct status. No mandatory OPS preparation course and no universal training-hour total is verified, so the path to meeting the experience requirement varies by individual. Details and edge cases are covered in our CRA requirements guide, and the training landscape is discussed on our CRA training page.

Fees and Application Timeline

The initial examination fee is $465 for OPS members and $590 for non-members. The non-member price includes an optional one-year OPS membership, and the $50 non-refundable application component is already included in these totals rather than added on top. If you need to retake the exam, the retest fee is $285.

Run the numbers on membership before you apply: the gap between the member and non-member initial fee is covered by the membership that the non-member price bundles in. For the full breakdown, see our CRA certification cost guide, and for scheduling logistics see CRA exam dates and deadlines.

How the Exam Is Scored

The exam is criterion-referenced. The passing standard is set using a Modified Angoff V competency approach, meaning the bar reflects what a minimally competent angiographer should know rather than how you rank against other test-takers. Results are reported on a scaled basis, and no current numeric cut score is publicly verified, so anyone quoting you a precise "you need X questions right" figure is guessing.

• 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 report by content area, which is valuable for targeting a retest.
• Timing of results: initial score reports are provisional pending a 72-hour statistical verification, and the program guide allows for reporting delays during exam-development cycles.

What Pass Data Does and Does Not Tell You

No current 2026 pass rate is publicly verified, and it is worth being candid about that. Historical OPS Board of Certification reports show 537 passes among 857 candidates tested (63%) across April 1997 through July 2018. That figure spans more than two decades and is not a current first-attempt rate. The BOC annual reports also show 9 passes in 14 written administrations (64%) in 2018, with 6 first-attempt passes among 10 individuals, though small counts like these swing widely and some of the underlying attempt narratives are internally inconsistent.

The honest takeaway is that the exam is passable but not trivial, and that small-cohort statistics should not drive your confidence up or down. Read the fuller discussion in CRA pass rate: what the data shows.

Keeping the Credential: Three-Year Renewal

CRA certification runs on a three-year recertification cycle that begins January 1 of the year after you earn certification. You have two routes to renew:

1. Earn 15 continuing education credits (CECs) during the cycle, including at least five from attending official OPS or OPS BOC pre-approved courses or workshops.
2. Retest by the end of year three, paying the examination fee with no additional recertification fee.

Within the CEC route, 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. The renewal fee is $100 for members and $225 for non-members.

Where the Credential Fits in a Career

The CRA credential tends to matter most in clinical environments where angiography is routine: retina-focused practices, hospital-based ophthalmology departments, and academic centers. It can support a move into lead imaging roles, training responsibilities, or positions that require demonstrated competence in dye-based imaging. Whether the investment makes sense for you depends on your current employer, local market, and goals, which we examine in is CRA certification worth it. For an overview of the credential in broader terms, our CRA certification page and what is a CRA explainer are good companions to this article.

Sequencing Your Preparation Around the Weights

You do not need an elaborate method, just a plan that mirrors the blueprint. Because fluorescein angiography and fundus photography carry 48% of the weight, they deserve the most calendar time and the earliest start. A simple sequencing example, adjustable to your own timeline:

Once you have worked through the content, practice under realistic conditions. Our CRA practice tests are built around the exam's multiple-choice format, and our CRA study guide and one-page cheat sheet help you consolidate. You can also try a timed practice set to check your pacing against the two-hour limit before you book a Prometric seat.
