- CUNP is issued by CBUNA; the exam has 175 single-best-answer questions, a 4-hour limit, and no guessing penalty.
- The passing standard is 72%, set with the Angoff procedure, and it is separate from the 88% 2024 pass rate.
- The two blueprint axes each total 100%; never add all 11 domain percentages together.
- Urinary Tract Inflammations and Disorders (24%) and Assessment and diagnosis (35%) are the heaviest categories.
Identity and Issuer in 30 Seconds
CUNP stands for Certified Urologic Nurse Practitioner. The credential is issued by the Certification Board for Urologic Nurses and Associates (CBUNA). SUNA hosts CBUNA's certification information on its website, but SUNA is a separate organization, and membership in it is optional for sitting the exam. If you want the broader background first, start with What Is CUNP Certification? and then return to this page for the compressed facts.
Because several unrelated credentials share the same four letters, always confirm that a source is describing the urologic nurse practitioner credential before you trust any fee, date, or score it quotes. Everything on this page applies only to the CBUNA credential. The program carries ABSNC accreditation, and the current directory lists CUNP accreditation through December 2028.
Exam Format at a Glance
| Element | What to Know |
|---|---|
| Question count | 175 questions, including unscored pilot items |
| Question style | Single-best-answer multiple choice |
| Time limit | 4 hours |
| Guessing penalty | None, so answer every item |
| Passing standard | 72%, established using the Angoff procedure |
| Delivery | Follow the current issuer notice; recent CBUNA notices identify CMS as the testing agency with fully remote exams after application review, while the March 2025 handbook and legacy pages still mention testing centers |
Since the pilot items are unscored but unmarked, you cannot tell which questions count. Treat each one as scored and spend your time evenly. With 175 items in 240 minutes you have roughly 80 seconds per question, which is generous for single-best-answer items but tight if you stall on long clinical vignettes. For a deeper look at timing and difficulty, see How Hard Is the CUNP Exam?
The Two-Axis Blueprint (Do Not Add It Up)
The most commonly misunderstood fact about this exam is how the blueprint is built. CBUNA's official CUNP examination blueprint was adopted in April 2023 and took effect in January 2024. It lists 11 categories, but they sit on two separate axes:
- Axis I, Patient Problems: Domains 1 through 6.
- Axis II, Nurse Practitioner Activities: Domains 7 through 11.
Every question is classified on both axes at once. A question might be, for example, a stone-related patient problem (Axis I) that asks you to assess and diagnose (Axis II). Each axis independently totals 100%. If you add all 11 percentages you get 200%, which double-counts the exam. The "11" is simply the number of published categories across both axes. For the full domain-by-domain walkthrough, see CUNP Exam Domains: Complete Guide to All 11 Content Areas.
Axis I: Patient Problem Cheat Notes
| Domain | Weight |
|---|---|
| 1. Common Pediatric Disorders | 6% |
| 2. Urinary Tract Inflammations and Disorders | 24% |
| 3. Voiding Dysfunctions, Including Incontinence | 23% |
| 4. Obstructive Uropathies and Trauma, Including Stones and BPH | 20% |
| 5. Sexual Dysfunctions, Disorders of Genitalia and Male Infertility | 10% |
| 6. Genitourinary Lesions, Benign and Malignant | 17% |
The first three heavy domains (2, 3, and 4) together make up 67% of the patient-problem axis. That concentration should shape your study hours.
Domain 2: Urinary Tract Inflammations and Disorders (24%)
The single largest patient-problem category. Expect questions that require you to separate infection from inflammation and to choose the next best step.
- Uncomplicated versus complicated and recurrent urinary tract infection, and how that changes workup
- Culture-driven versus empiric thinking, and when imaging or referral is warranted
- Cystitis, pyelonephritis, prostatitis, epididymitis, and urethritis as distinct presentations
- Interstitial cystitis/bladder pain presentations and how they differ from infection
Domain 3: Voiding Dysfunctions, Including Incontinence (23%)
Nearly a quarter of the patient-problem axis. Classification drives management, so know the types cold.
- Stress, urge, mixed, and overflow incontinence, and what separates each on history and exam
- Overactive bladder and neurogenic bladder considerations
- Retention and incomplete emptying, including post-void residual interpretation
- Behavioral, pharmacologic, and procedural options at a decision-making level
Domain 4: Obstructive Uropathies and Trauma, Including Stones and BPH (20%)
Obstruction is time-sensitive, so questions often hinge on recognizing urgency.
- Upper tract versus lower tract obstruction and the red flags that demand prompt intervention
- Stone evaluation, imaging choice, and conservative versus procedural management
- BPH assessment, symptom scoring concepts, and medical versus surgical pathways
- Genitourinary trauma recognition and initial evaluation
Domain 6: Genitourinary Lesions, Benign and Malignant (17%)
At 17%, this is more than many candidates expect. Know the presentations that should trigger a cancer workup.
- Hematuria evaluation logic, including when it is a mandatory trigger for further workup
- Bladder, kidney, prostate, and testicular lesions: presentation, diagnostic pathway, referral timing
- Benign versus malignant distinctions and surveillance principles
Domains 1 (6%) and 5 (10%) are smaller, but they are narrow and highly testable. Pediatric items often turn on age-appropriate norms and when a finding is expected versus concerning. Domain 5 covers sexual dysfunction, genital disorders, and male infertility, where candidates who see mainly voiding and stone patients tend to be weakest.
Axis II: NP Activity Cheat Notes
| Domain | Weight |
|---|---|
| 7. Assess and diagnose pathologic processes and complications of urologic conditions | 35% |
| 8. Prescribe/perform interventions, including treatments, therapies, and procedures | 30% |
| 9. Educate patient, family, other health care professionals and the public | 28% |
| 10. Consult for and with peers and other health care professionals | 4% |
| 11. Participate in practice management and research activities | 3% |
Together, Domains 7 through 9 account for 93% of the activity axis. Domains 10 and 11 (4% and 3%) cover consultation and practice management, such as case management, coordination of care, and quality improvement. They are small, but they are also the easiest points to pick up with a short review, so do not skip them entirely.
Education (28%) is the domain most often underestimated. Expect items on counseling about catheter care, fluid and bladder habits, medication adherence, pelvic floor and behavioral strategies, self-catheterization teaching, and clear expectations after procedures. The correct answer is usually the one that is accurate, patient-centered, and safe.
Eligibility Snapshot
For U.S. applicants, CBUNA's current requirements include all of the following:
- Completion of a nationally accredited nursing program
- An MSN or DNP
- Two years of nurse practitioner experience
- At least 800 clinical urologic patient-care hours within the preceding three years
- State recognition as a nurse practitioner
- Current national NP certification accepted by CBUNA
International applicants need the specified approved education and practice experience plus NP recognition from the nursing regulator in their country or province. The exam is in English, and CBUNA may review transcripts. For a fuller breakdown, see CUNP Requirements: Eligibility, Prerequisites & How to Qualify.
Fees and Registration Mechanics
| Item | SUNA Member | Nonmember |
|---|---|---|
| Initial exam fee | USD 350 | USD 445 |
| Discounted retake (one, within 12 months) | USD 250 | USD 345 |
| Continuing-education renewal | USD 300 | USD 325 |
The sequence is: confirm eligibility, submit the application, wait for application review, and then schedule using the delivery instructions CBUNA currently publishes. Only one discounted retake is offered, and it must fall within 12 months, so if a first attempt does not go your way, build the retake into a realistic study plan rather than rebooking in a hurry. Because SUNA membership is optional, run the numbers: the exam-fee difference is USD 95 for the initial attempt, so compare that against the membership cost you would pay. Full pricing context is in CUNP Certification Cost: Complete Pricing Breakdown, and scheduling details are in CUNP Exam Dates: Testing Windows, Deadlines & Scheduling.
Passing Standard vs. Pass Rate
Two numbers circulate and they are often confused:
- 72% is the passing standard, established using the Angoff procedure, in which subject-matter experts judge how a minimally competent candidate would perform on each item.
- 88% is the published 2024 administration-based pass rate: 22 passes from 25 test administrations involving 24 unique candidates, because one candidate tested twice.
Key Takeaway
The pass rate is a historical description of a very small cohort, not a threshold and not a prediction. With only 25 administrations, a single result moves the percentage noticeably. Study to the 72% standard, not to the cohort rate.
For more context, see CUNP Passing Score: Exactly What You Need to Pass and CUNP Pass Rate: What the Data Shows.
Renewal Cheat Sheet
- Cycle: Certification lasts three years and expires on December 31 of the renewal year.
- Baseline requirements: Current licensure and current CBUNA certification, plus 800 hours of urologic practice during the three-year certification period.
- Two routes: Reexamination, or 36 approved urology contact hours earned in that period, with no more than 10 of those hours in nephrology.
- Continuing-education renewal fee: USD 300 for members, USD 325 for nonmembers.
Some recertification pages retain older delivery wording, so use the issuer's current recertification and eligibility pages as your authority. Track your contact hours as you earn them, and keep the nephrology cap in mind so none of your hours are disqualified at renewal.
A CUNP-Specific Study Sequence
The blueprint tells you where the points are. A sensible sequence weights your calendar to the heavy domains while saving time to cross-train on the activity axis. For a longer plan, see the CUNP Study Guide: How to Pass on Your First Attempt.
Domain 2 and Domain 3 (47% of Axis I combined)
- Infection and inflammation: classification, workup logic, referral triggers
- Incontinence types, overactive bladder, retention, and post-void residual interpretation
Domain 4 and Domain 6 (37% of Axis I combined)
- Obstruction urgency, stone and BPH pathways, trauma recognition
- Hematuria evaluation and lesion workup, with benign versus malignant distinctions
Domains 1 and 5, plus Axis II skills
- Pediatric norms and male infertility, genital disorders, sexual dysfunction
- Practice labeling each question by activity: assess, intervene, or educate
Mixed timed sets
- Full-length pacing at roughly 80 seconds per item
- Quick passes through Domains 10 and 11 for easy points
Use timed question sets from the CUNP practice test to check that you are comfortable with single-best-answer wording, where two options may both seem reasonable and only one is best. Reviewing why a distractor is wrong teaches more than confirming why the right answer is right.
Frequently Asked Questions
The exam has 175 single-best-answer multiple-choice questions, including unscored pilot items, with a 4-hour limit. There is no guessing penalty, so answer every question.
No. Domains 1-6 form Axis I (Patient Problems) and Domains 7-11 form Axis II (Nurse Practitioner Activities). Each axis independently totals 100%, and every question is classified on both, so adding all 11 would double-count the exam.
The passing standard is 72%, set using the Angoff procedure. The 88% figure is the published 2024 administration-based pass rate (22 passes from 25 administrations, 24 unique candidates). It describes a past cohort and does not predict an individual result.
The initial fee is USD 350 for SUNA members or USD 445 for nonmembers. One discounted retake within 12 months costs USD 250 for members or USD 345 for nonmembers. SUNA membership is optional.
Certification lasts three years and expires December 31 in the renewal year. Renewal requires current licensure and CBUNA certification, 800 hours of urologic practice in the period, and either reexamination or 36 approved urology contact hours, with no more than 10 in nephrology. The continuing-education renewal fee is USD 300 for members or USD 325 for nonmembers.
Keep this sheet beside you as you plan, and check the CUNP certification overview and CBUNA's current notices for anything that may have changed since this page was last verified. When you are ready to test your recall under realistic conditions, head to the main practice test site.
