The 70% Standard: What the CURN Passing Score Actually Is
If you are searching for the passing score on the Certified Urologic Registered Nurse (CURN) examination, the answer is short: the published passing standard is 70%. That standard is established by the Certification Board for Urologic Nurses and Associates (CBUNA), the issuer of the credential. SUNA hosts CBUNA's certification information on its website, but SUNA is a separate organization, and the passing standard belongs to the certification board.
That single number comes with several details worth understanding before you sit for the exam. The test contains 150 single-best-answer multiple-choice questions, includes unscored pilot items, allows 3 hours, and carries no penalty for guessing. Those four facts shape how you should think about 70%, and this article walks through each of them in turn.
For the broader picture of what the exam demands, see our guide on how hard the CURN exam is, and for the eligibility side of the equation, our CURN requirements breakdown.
How CBUNA Sets the Cut Score (Angoff Explained)
The 70% figure is not an arbitrary round number and it is not curved against other test takers. CBUNA states that the passing standard is established using the Angoff procedure, a criterion-referenced standard-setting method. In an Angoff process, a panel of subject-matter experts reviews each exam item and estimates the probability that a minimally competent urologic nurse would answer it correctly. Those judgments are aggregated into a cut score reflecting what minimum competence looks like.
What this means for you in practical terms:
- You are measured against a competence standard, not against other candidates. A strong cohort does not raise the bar, and a weak cohort does not lower it.
- The standard reflects what a minimally competent certified urologic nurse should know. It is a floor for safe, knowledgeable practice, so thorough clinical preparation is the right approach rather than test-taking tricks.
- Different exam forms are built to the same standard. The goal of the process is consistency in what 70% represents, whichever set of items you receive.
The authoritative source for the passing standard and scope is CBUNA's Exam Details page. Always confirm current details there, because certification policies can be updated between handbook editions.
Why Your Score Spans Two Blueprint Axes
The CURN blueprint is unusual, and misreading it is one of the most common errors candidates make. CBUNA's official blueprint, adopted in October 2017 and effective October 2018, classifies every exam question on two axes at once:
- Axis I, Patient Problems covers Domains 1 through 6.
- Axis II, Nursing Activities covers Domains 7 through 11.
Each axis independently totals 100%. A single question might be a Domain 4 patient-problem item (for example, a stone-related scenario) and simultaneously a Domain 8 nursing-activity item (planning and implementing care). The header count of 11 domains is simply the number of published categories listed across both axes. If you add all 11 percentages together you get 200%, which double-counts the examination.
| Axis | Domain | Weight |
|---|---|---|
| Axis I: Patient Problems | 1. Pediatric anomalies, embryology and common pediatric neoplasms | 5% |
| 2. Urinary tract inflammations and disorders | 18% | |
| 3. Voiding dysfunctions, including incontinence | 24% | |
| 4. Obstructive uropathies and trauma, including stones and BPH | 25% | |
| 5. Infertility and sexual dysfunctions, disorders of male genitalia | 5% | |
| 6. Genitourinary cancers | 23% | |
| Axis II: Nursing Activities | 7. Assess and monitor patients who have urologic conditions and procedures/treatments | 25% |
| 8. Plan and implement care of patients who have urologic conditions and procedures/treatments | 30% | |
| 9. Teach patients, significant others, other health professionals, and the public about prevention and management of urologic conditions | 25% | |
| 10. Evaluate outcomes of care given to patients who have urologic conditions and procedures/treatments | 12% | |
| 11. Ensure professional practice in promoting patient outcomes (consultation, staff development, quality improvement, research) | 8% |
The practical takeaway: you do not need 70% in each domain, and you do not "pass" one axis and "fail" another. The 70% standard applies to the exam as a whole. But because every item sits on both axes, strength in a heavy domain such as Domain 4 (25%) or Domain 8 (30%) pulls up your overall result across many items simultaneously. Our complete guide to the CURN exam domains goes deeper on each content area.
Pilot Items, 150 Questions, and the Math of 70%
The 150 questions on the CURN exam include unscored pilot items. These are new questions CBUNA is trialing for future exams; they look identical to scored questions, and you cannot tell which ones they are. They do not count toward your result.
This matters for how you think about the 70% standard. You may be tempted to calculate exactly how many questions you need correct out of 150, but the published materials describe the standard as 70% and do not give a fixed number of required correct answers that you can rely on. Since the number of scored items is smaller than 150, treat any "I need X out of 150" arithmetic with caution. Instead, adopt these habits:
- Answer every question. With no guessing penalty, a blank is always worse than a reasoned guess.
- Do not panic over an odd item. If a question seems unfamiliar or unusually phrased, it may be an unscored pilot question. Make your best choice and move on.
- Pace for 150. Three hours across 150 items leaves roughly 72 seconds per question on average. Flag long scenario items and return to them rather than letting one stem consume five minutes.
Pass Rate vs. Passing Score: Keep Them Separate
Candidates often conflate two very different numbers. The passing score is the 70% standard you must meet. The pass rate is the percentage of past candidates who met that standard in a given period. CBUNA's published 2024 administration-based pass rate was 68%, rounded from 21 passes in 31 test administrations involving 26 unique candidates. Five of those candidates tested twice.
Read that statistic carefully:
- It is a small cohort. With only 26 unique candidates, a handful of results can move the percentage substantially from one year to the next.
- It counts administrations, not just people. Because five candidates tested twice, the 31 administrations exceed the 26 individuals.
- It is not your probability of passing. This historical cohort rate is separate from the passing standard and does not predict an individual result. Your preparation, clinical exposure, and test-day performance determine your outcome.
For a fuller treatment of what this data does and does not tell you, see our analysis of the CURN pass rate.
Setting Score Targets by Domain
Because you need 70% overall rather than 70% per domain, smart candidates aim for a deliberate profile: very strong in the heavy categories, solid in the mid-weight ones, and adequate in the light ones. Here is how to think about the highest-leverage areas.
Domain 4: Obstructive Uropathies and Trauma (25%)
The largest patient-problem category. Expect questions on stones, BPH, and genitourinary trauma, including recognition, nursing priorities, and post-procedure care.
- Stone management: symptom recognition, hydration and strain-urine teaching, post-lithotripsy and ureteroscopy care
- BPH: medication classes, procedural options, and post-operative bladder irrigation concerns
- Trauma: assessment priorities and warning signs requiring escalation
Domain 3: Voiding Dysfunctions, Including Incontinence (24%)
The second-heaviest patient-problem area, and one where bedside experience translates directly into points.
- Incontinence types and how assessment findings distinguish them
- Catheterization principles, bladder training, and conservative management
- Retention versus overflow presentations and nursing responses
Domain 6: Genitourinary Cancers (23%)
Nearly a quarter of patient-problem items. Know the diagnostic pathway, treatment modalities, and nursing care that follows.
- Bladder, prostate, and kidney cancer: presentation, staging concepts, and treatment overviews
- Intravesical therapy, surgical diversions, and ostomy or stoma care teaching
- Symptom management and patient support across the treatment course
Domain 8: Plan and Implement Care (30%) and Domain 7: Assess and Monitor (25%)
Because Axis II questions overlay the patient-problem content, these two activity domains together shape a large share of your score. Practice reading each scenario for what the nurse should do: assess first, then intervene.
- Prioritizing nursing actions in postoperative and procedural scenarios
- Recognizing complications early and responding appropriately
Do not neglect Domain 9 (patient and public teaching, 25%). Teaching items often reward the answer that is clear, safe, and appropriate to the patient's understanding. Domain 2 (urinary tract inflammations and disorders, 18%) is also substantial, so infection prevention, catheter-associated concerns, and symptom recognition deserve real study time. Domain 1 (5%), Domain 5 (5%), and Domain 11 (8%) are lighter, but they are not zero, so give them a focused review pass rather than skipping them. Our CURN study guide and one-page CURN cheat sheet help you organize this material.
Fees, Delivery, and the Discounted Retake
The passing score is easier to approach calmly when you know the financial and logistical safety net. CBUNA's published initial examination fee is:
| Fee Type | SUNA Member | Nonmember |
|---|---|---|
| Initial exam | USD 325 | USD 420 |
| One discounted retake (within 12 months) | USD 225 | USD 320 |
SUNA membership is optional, so the member rate is a choice rather than a requirement. If you do not pass, the discounted retake must be used within 12 months of your first attempt, so factor that window into any retake planning. For a full financial picture, including renewal, see our CURN certification cost breakdown.
On delivery, there is an important caveat. Current CBUNA notices identify CMS as the testing agency and specify fully remote examinations after application review. However, the March 2025 handbook, legacy C-NET/PSI pages, and some recertification wording still retain testing-center instructions. Because these sources conflict, do not rely on a third-party summary for scheduling. Follow the current issuer application and scheduling instructions on the CBUNA Becoming Certified page, and check timing details in our guide to CURN exam dates and scheduling.
A Domain-Weighted Study Sequence
Rather than a generic schedule, sequence your preparation by blueprint weight and by how much each area benefits from your clinical experience. This is one possible structure for a roughly six-week plan; compress or extend it based on your background.
Heavy patient-problem domains
- Domain 4 (obstructive uropathies and trauma, 25%) first, since it is the largest single category
- Domain 3 (voiding dysfunctions, 24%) next, pairing it with your bedside catheter and incontinence experience
Cancers and infections
- Domain 6 (genitourinary cancers, 23%) including treatment modalities and diversion care
- Domain 2 (urinary tract inflammations and disorders, 18%)
Nursing-activity lens
- Re-read prior material asking "what would the nurse assess, plan, teach, and evaluate?" for Domains 7 through 10
- Drill priority-of-care and patient-teaching scenarios
Light domains and full-length practice
- Quick passes on Domains 1, 5, and 11
- Timed practice sets under the 3-hour constraint, then review every miss
Use full-length timed sets from the CURN practice test to check whether your overall accuracy is comfortably above 70% rather than hovering at it. If you are scoring right at the line in practice, build in a margin: pilot items and test-day nerves mean you want a buffer, not a coin flip. Domain-level results from your practice exams show you where to spend the remaining days.
Key Takeaway
Aim to practice at a score meaningfully above 70%, not at it. The standard is a minimum competence threshold, and a buffer protects you from unscored items, unfamiliar phrasing, and ordinary test-day variance.
After You Pass: Certification Period and Renewal
Once you meet the passing standard, certification lasts three years and expires on December 31 of the renewal year. To recertify, you need current licensure and CBUNA certification, 800 hours of urologic practice during the three-year certification period, and either reexamination or 36 approved urology contact hours earned in that period, with no more than 10 of those hours in nephrology. Continuing-education renewal costs USD 250 for members or USD 275 for nonmembers.

Frequently Asked Questions
The published passing standard is 70%, established by CBUNA using the Angoff procedure. It reflects a minimum competence standard rather than a ranking against other candidates.
No. The exam has no guessing penalty, so you should answer every one of the 150 single-best-answer questions. Leaving an item blank can never improve your result.
No. The 150 questions include unscored pilot items that CBUNA is testing for future exams. They are indistinguishable from scored items, so treat every question seriously and answer each one.
No. The 68% figure is the published 2024 administration-based pass rate (21 passes in 31 administrations among 26 unique candidates). The passing score is 70%. The pass rate is a small historical cohort statistic and does not predict your individual result.
You may retake the exam. CBUNA offers one discounted retake within 12 months, priced at USD 225 for SUNA members or USD 320 for nonmembers. Review your weaker domains, especially the high-weight categories, before rescheduling.
