CURN Requirements 2026: Eligibility, Prerequisites & How to Qualify

What This Credential Is and Who Issues It

CURN stands for Certified Urologic Registered Nurse. The credential is issued by the Certification Board for Urologic Nurses and Associates (CBUNA). SUNA, the Society of Urologic Nurses and Associates, hosts CBUNA's certification information on its website, but the two are separate organizations. That distinction matters in practice: your eligibility is determined by CBUNA, and SUNA membership is optional. It only affects the price you pay.

If you are still orienting yourself to the credential itself, our explainers on what CURN certification is and what CURN stands for cover the basics. This article focuses on the gatekeeping question: do you qualify, and what exactly do you need to document before you apply?

The Four Core U.S. Eligibility Requirements

For nurses in the United States and its territories, CBUNA's eligibility standard has four parts. All four must be satisfied; strength in one cannot offset a gap in another.

Education and general RN experience

The education requirement is satisfied by graduating from a nationally accredited nursing program. The two-year experience requirement is about general RN practice and is separate from the urology-specific hour count. A nurse with two years as an RN who has only recently moved into a urology setting may meet the general experience threshold but still be short on urologic hours.

License status is not a formality

"Unrestricted" is the word to read carefully. A license that is current but carries restrictions, conditions, or active disciplinary limits does not meet the standard. Before you start an application, verify your license status on your state board's lookup tool and confirm the expiration date falls well after the date you plan to apply and test.

Understanding the 800 Clinical Hours

The 800-hour requirement is the one that most often determines timing. It calls for clinical urologic patient-care hours accrued within the preceding three years. Two phrases carry the weight: "clinical patient-care" and "urologic."

• Clinical patient-care means hands-on care of patients, not hours spent exclusively in unrelated administrative work.
• Urologic means the patients and procedures are genuinely within the urology scope, such as voiding dysfunction, stones and obstruction, urinary tract infections, or genitourinary cancers.
• Preceding three years means the window moves with your application date. Hours from a position you left four years ago will not count toward the current window.

A rough sense of scale

Eight hundred hours is a threshold, not a stretch goal. A full-time nurse working in a dedicated urology clinic, procedure unit, or urologic surgical floor can reach it well within the window. Nurses in mixed settings, such as a med-surg unit with a urology overflow, or a float role, should keep a running log, because the share of their hours that is demonstrably urologic may be lower and harder to reconstruct later.

Because this is a self-reported and verifiable figure, keep documentation: schedules, supervisor attestation, or employer verification letters. If a nurse manager can confirm that your role is predominantly urologic, that conversation is easier to have before you apply than after a request for supporting information arrives.

International Applicants

CBUNA accepts international applicants, but the pathway has its own prerequisites. Rather than a U.S. RN license, international candidates need the specified approved nursing education and practice experience, plus first-level general nursing registration in their country. The examination is administered in English, so language readiness is part of your planning, not just a footnote. CBUNA may also review transcripts as part of evaluating your education.

Because the exact documentation list for international applicants is set by the issuer and can be updated, treat the official eligibility page (linked in the sources below) as the controlling document. Gather your transcripts, registration proof, and practice-experience verification early, since obtaining documents across borders is usually the slowest step.

Application, Fees and Delivery

Once you meet the requirements, the application is reviewed before you are cleared to test. The fee structure depends on whether you belong to SUNA:

The initial-fee gap between member and nonmember pricing is USD 95, so run the numbers on whether membership dues make sense for you; for some candidates the savings across the exam and a later renewal justify joining, and for others they do not. Our full CURN certification cost breakdown walks through those trade-offs in more detail.

Because testing-window and scheduling specifics can shift with the agency transition, check our guide to CURN exam dates and scheduling and the issuer's own pages together rather than relying on any single source.

The Exam You Are Qualifying For

Meeting the requirements gets you to the exam, so it helps to know what you are walking into. The CURN examination has 150 single-best-answer multiple-choice questions, including unscored pilot items, with a 3-hour time limit and no guessing penalty. The passing standard is 70%, set using the Angoff procedure, a criterion-referenced method in which subject-matter experts judge how a minimally competent candidate would perform on each item. Because there is no penalty for wrong answers, you should answer every question. For a closer look at scoring, see our explainer on the CURN passing score.

On historical performance, CBUNA's published 2024 administration-based pass rate was 68%, rounded from 21 passes in 31 test administrations involving 26 unique candidates, with five candidates testing twice. That is a small cohort and a historical statistic, distinct from the 70% passing standard, and it does not predict your individual result. We unpack the nuance in our CURN pass rate analysis and our guide to how hard the CURN exam is.

How the blueprint is built: two axes

CBUNA's official blueprint, adopted October 2017 and effective October 2018, classifies every question on two axes at once. Axis I covers patient problems (Domains 1-6) and Axis II covers nursing activities (Domains 7-11). Each axis independently totals 100%. The 11 headings are the number of published categories across both axes; adding all 11 percentages together would double-count the exam. In other words, a single question about, say, post-procedure care for a patient with a ureteral stone belongs to a patient-problem category and a nursing-activity category at the same time.

The practical takeaway: the three biggest patient-problem categories (obstruction and trauma, voiding dysfunction, and genitourinary cancers) account for 72% of Axis I. That is where an experienced urology nurse's daily work and the exam's weighting line up. For a deeper walk-through, see our complete guide to the CURN exam content areas.

The Accreditation Notice You Should Know About

Transparency matters when you are investing time and money, so here is a caveat that applies to this credential. CBUNA's FAQ reports that the CURN program's ABSNC accreditation lapsed in 2025 and that reinstatement was in progress as of March 2026. We have not verified any subsequent reinstatement, and ABSNC's current directory lists CUNP (the sister credential for nurse practitioners) but not CURN. CBUNA continues to accept CURN examination applications.

Staying Qualified: Certification Period and Renewal

Qualifying once is not the end of the requirements. Certification lasts three years and expires on December 31 of the renewal year, so your actual window may be a little shorter or longer than 36 months depending on when you certify. Recertification has its own conditions:

• Current licensure and current CBUNA certification
• 800 hours of urologic practice during the three-year certification period
• Either reexamination, or 36 approved urology contact hours earned within that period, including no more than 10 nephrology hours

Renewing by continuing education costs USD 250 for SUNA members or USD 275 for nonmembers. Two planning habits pay off. First, keep logging your urologic hours after you pass; the same documentation discipline that got you through the initial application will make renewal painless. Second, track your contact hours as you earn them, and watch the nephrology cap so you do not discover late that some of your credits exceed the allowed share.

Turning Eligibility Into a Domain-Based Plan

Once you clear the requirements, the next question is sequencing your preparation. Because the exam's weighting is uneven, a sensible plan front-loads the heavy categories rather than studying everything equally. Here is one way to map a short runway tied to the blueprint:

Remember that because every question is tagged on both axes, studying a patient problem should always include what the nurse assesses, implements, teaches, and evaluates for that condition. Our CURN study guide expands this into a fuller approach, and the CURN cheat sheet is a handy final-week review. When you want to test your readiness against exam-style items, try the practice questions on the CURN Exam Prep practice test site, and use them to identify which of the heavy domains still need work.

If you are still deciding whether the credential makes sense for your career, it helps to look at what the work looks like in practice. Our overviews of CURN jobs and the CURN salary guide give context on where certified nurses work and how employers think about the credential. When you are ready to measure yourself, the full practice exam is a good checkpoint before you submit your application.
