CURN Certification

What the CURN Credential Actually Is

CURN stands for Certified Urologic Registered Nurse. It is a specialty certification for registered nurses who deliver direct care to patients with urologic conditions, and it is administered by the Certification Board for Urologic Nurses and Associates (CBUNA). SUNA, the Society of Urologic Nurses and Associates, hosts the certification information on its website, but CBUNA is the certifying body and SUNA is a separate organization. You do not need to join SUNA to apply, though membership lowers your fees.

If you are still orienting yourself to the basics, our explainers on what CURN certification is and what CURN stands for cover the terminology. This article focuses on the credential itself: how you qualify, how the exam is built, and how to prepare for the topics it actually tests.

Who Qualifies to Sit for the Exam

CBUNA's eligibility rules are practice-based, which means a general nursing background alone is not enough. U.S. applicants need all of the following:

• Completion of a nationally accredited nursing program
• Two years of experience as a registered nurse
• At least 800 clinical urologic patient-care hours within the preceding three years
• A current, active, unrestricted RN license in the United States or its territories

International applicants must document the specified approved nursing education and practice experience along with first-level general nursing registration. The examination is administered in English, and CBUNA may review transcripts as part of the application. For a fuller walkthrough of prerequisites, see our guide to CURN requirements and how to qualify.

Application, Delivery, and Fee Mechanics

The initial examination fee is USD 325 for SUNA members and USD 420 for nonmembers. If you do not pass, CBUNA offers one discounted retake within 12 months at USD 225 for members or USD 320 for nonmembers. Because membership is optional, the practical question is whether the savings on the exam (and later on renewal) justify the dues for your situation. Our CURN certification cost breakdown walks through the full pricing picture.

Check the Current Delivery Instructions

Delivery details are an area where published sources do not fully agree. Current CBUNA notices identify CMS as the testing agency and describe fully remote examinations after your application is reviewed. However, the March 2025 handbook, legacy C-NET/PSI pages, and some recertification wording still carry testing-center instructions. Treat the issuer's current application and scheduling instructions as authoritative, and confirm them when you apply rather than relying on older PDFs or third-party pages. For timing questions, see our page on CURN exam dates, deadlines, and scheduling.

Exam Format, Timing, and Passing Standard

The CURN exam consists of 150 single-best-answer multiple-choice questions. Some of those items are unscored pilot questions used to evaluate future content, and you cannot tell which ones they are, so every question deserves your full effort. You have 3 hours, and there is no penalty for guessing, so you should never leave an item blank.

The passing standard is 70%, established through the Angoff procedure. In that method, subject-matter experts judge how a minimally competent candidate would perform on each item, and those judgments set the cut point. The practical implication is that the standard reflects competence expectations rather than a curve against other test takers. You can read more about what that means in our explainer on the CURN passing score.

Reading the Two-Axis Blueprint

The most commonly misunderstood feature of the CURN is its blueprint. CBUNA's official examination blueprint (adopted October 2017, effective October 2018, and still retained on the current Exam Details page and in the full 2025 handbook) lists 11 categories, but they are not 11 slices of a single pie. They sit on two separate axes:

• Axis I, Patient Problems: Domains 1 through 6
• Axis II, Nursing Activities: Domains 7 through 11

Every question on the exam is classified on both axes at once. A single item might be, for instance, an obstructive uropathy question (Axis I) that asks you to plan and implement care (Axis II). Each axis independently totals 100%, so adding all 11 percentages would double-count the exam. The "11" simply counts the published categories across both axes. Our complete guide to the CURN exam domains explores how the two axes interact.

Axis I: Patient Problem Domains in Depth

Four of the six patient-problem domains account for 90% of Axis I, so that is where most of your content review belongs.

Domains 1 (pediatric anomalies, embryology and common pediatric neoplasms) and 5 (infertility and sexual dysfunctions, disorders of male genitalia) are each 5%. They are small, but nurses who work exclusively with adults often find pediatric content the least familiar, so a short, targeted review pays off. Our CURN study guide suggests how to allocate time across these areas.

Axis II: Nursing Activity Domains in Depth

Axis II describes what you are being asked to do with the clinical content. Care planning and implementation (Domain 8) is the largest activity at 30%, followed by assessment and monitoring (Domain 7) and patient and professional education (Domain 9), each at 25%.

• Assess and monitor (25%): Interpreting findings, recognizing deterioration, and knowing what to watch for after urologic procedures and treatments.
• Plan and implement care (30%): Selecting and carrying out the right intervention, prioritizing among competing needs, and managing devices and therapies.
• Teach (25%): Educating patients, significant others, other health professionals, and the public about prevention and management. Education carries as much weight as assessment, so expect scenario questions about what to tell a patient and how to confirm understanding.
• Evaluate outcomes (12%): Judging whether interventions worked and what to do when they did not.
• Ensure professional practice (8%): Consultation, staff development, quality improvement, and research.

Putting the Published Pass Rate in Context

CBUNA's published 2024 statistics report an administration-based pass rate of 68%. That figure is rounded from 21 passes in 31 test administrations, involving 26 unique candidates, five of whom tested twice. Two cautions apply. First, the cohort is small, so a handful of results can move the percentage noticeably. Second, this historical rate is separate from the 70% passing standard and says nothing about how you personally will perform. A candidate with solid urologic experience and structured preparation is not bound by a cohort average. For a deeper discussion, read our CURN pass rate analysis and how hard the CURN exam is.

A CURN-Specific Study Sequence

Generic scheduling matters less than sequencing the content by blueprint weight. The outline below front-loads the largest Axis I domains, then layers in the activity skills, and leaves the small domains for targeted review.

Keeping the Credential: Renewal Paths

Certification lasts three years and expires on December 31 of the renewal year. To recertify, you need current licensure and current CBUNA certification, plus 800 hours of urologic practice during the three-year certification period. You then choose one of two routes:

1. Reexamination: Retake the exam.
2. Continuing education: Earn 36 approved urology contact hours within the certification period, with no more than 10 of those hours in nephrology. The continuing-education renewal fee is USD 250 for members or USD 275 for nonmembers.

Because the 36 hours must be earned within the certification period and are capped on nephrology content, plan your education across the three years rather than compressing it into the final months.

The Accreditation Caveat to Know About

Transparency matters when you invest in a credential. CBUNA's FAQ reports that the ABSNC program accreditation for CURN lapsed in 2025, and that reinstatement was in progress as of March 2026. No subsequent reinstatement has been verified, and ABSNC's current directory lists CUNP but not CURN. CBUNA continues to accept CURN examination applications. If accreditation status matters to your employer, your state, or your own career plans, verify the current standing directly with CBUNA and ABSNC before you apply. This does not change the exam content or eligibility rules described above, but it is worth factoring into your decision, alongside the points in our analysis of whether CURN certification is worth it.

Where the Credential Carries Weight

CURN is most relevant where urologic nursing is concentrated:

• Urology clinics and ambulatory surgery settings
• Hospital urology and surgical units
• Urologic oncology and continence-focused practices
• Dialysis-adjacent and nephrology-urology programs

The credential signals documented practice hours and verified specialty knowledge, which can support internal promotion, clinical ladder advancement, or preference in hiring where managers value specialty certification. Compensation effects vary by employer and region, so we avoid quoting specific figures here; our CURN salary guide and CURN jobs overview discuss what to ask during negotiations and which settings tend to recruit certified nurses.
