- Initial exam cost is $350 total: a $100 registration/administration fee plus a $250 examination fee.
- The 120-question exam runs two 60-question blocks at 60 minutes each, excluding a 15-minute tutorial and 15-minute break.
- Scores generally arrive eight to ten weeks after administration, so schedule the exam well ahead of any job or credentialing deadline.
How CAQ-Nephrology Scheduling Actually Works
Searching for "PA-CN exam dates 2026" tends to turn up one disappointing result: no tidy list of fixed national test days. The Certificate of Added Qualifications in Nephrology, issued by the National Commission on Certification of Physician Assistants (NCCPA) to PA-Cs who earn the designation PA-C, CAQ-Neph, doesn't work like a once-a-year paper exam. Initial testing is delivered through Pearson VUE test centers, which means your real "date" is an appointment you secure after NCCPA confirms your eligibility.
That distinction shapes everything on this page. Rather than listing dates that may not exist, this guide explains the machinery that determines when you can sit: the eligibility clock, the registration steps, the attestation window, the score turnaround, and the maintenance windows that apply later in the credential's ten-year cycle. For the full eligibility picture, see our PA-CN requirements guide.
Why There Is No Single Published Exam Date to Circle
Candidates coming from other credentials often expect a spring-or-fall testing window. For the nephrology CAQ, the practical planning unit is different. You complete the application, NCCPA confirms what is satisfied, and you then book a slot at a Pearson VUE test center. Because the credential is a specialty add-on to initial PA-C certification, the volume of candidates is far smaller than for a primary certification exam, and scheduling is built around the individual candidate's readiness rather than a national exam day.
This is why a rigid "dates" article can mislead. Anyone quoting specific 2026 calendar days without citing NCCPA is guessing. The headline year in this article's title is an editorial publication year, not a signal that a newly versioned exam launches in 2026. If you want to understand what the exam covers rather than when it is offered, start with the complete guide to all 11 PA-CN content areas.
The Clocks That Really Control Your Timeline
Instead of one exam date, you are managing several overlapping clocks. Missing any of them can push your testing window back by months.
| Clock | Requirement | Why It Matters for Scheduling |
|---|---|---|
| Practice experience | 4,000 hours of total PA practice, including at least 2,000 in nephrology, within six years before attesting the experience requirement is satisfied | Only 2,000 of the 4,000 hours must be nephrology; do not misread it as 4,000 nephrology hours |
| Nephrology CME | 75 nephrology-focused Category I CME credits in the six years before exam application, with at least 25 in the preceding two years | The two-year sub-requirement is the one that quietly expires; check your transcript dates |
| Licensure and certification | Current PA-C and unrestricted U.S. PA licensure or unrestricted government-agency practice privileges; all held licenses unrestricted | A restriction on any held license can stall your eligibility |
| Process completion | The initial CAQ process must be completed within six years after initiation | Starting without a finish plan risks running out the clock |
ACLS is recommended rather than an additional mandatory course, so you do not need to hold a separate ACLS completion before you book. Our PA-CN requirements breakdown walks through each prerequisite in more detail.
Registration and Fee Mechanics
The initial examination costs $350 in total, and it is helpful to understand how that splits, because the two pieces are tied to different steps:
- $100 registration/administration fee
- $250 examination fee
That total covers the initial attempt only; it does not include optional preparation purchases such as the $50 NCCPA practice exam. For a fuller cost view, including preparation and renewal-related expenses, read the PA-CN certification cost breakdown.
From a scheduling standpoint, treat payment and application submission as the start of your real timeline. Because you cannot reliably book a test-center slot until NCCPA has processed your application, build in a buffer between submission and your target sitting rather than applying a week before you hope to test.
Attestation Timing: Before the Exam or 90 Days After
One of the more flexible features of the nephrology CAQ is the procedural and patient-management attestation. It can be submitted before the exam or within 90 days after score notification. That flexibility can help you sit for the exam sooner if your signer is hard to reach, but it also creates a hidden deadline: the award requires both a passing exam result and completion of the non-exam requirements.
Who Can Sign the Attestation
The attestation addresses relevant knowledge and performance, including management within at least one listed nephrology practice setting.
- A collaborating physician or lead/senior PA who works in nephrology and knows your practice
- A physician or PA postgraduate program director, for a PA enrolled in or graduated from that program
- Practice settings listed: end-stage renal disease, chronic kidney disease, kidney transplantation, or acute inpatient dialysis
- No separate timed practical assessment is required, and you do not need employment in every nephrology subspecialty
The scheduling lesson: do not let a passing score sit unused. If you pass but your signer is on leave, the 90-day post-notification window starts running from your score notification, not from when you finally track down the form. Ask your signer early, even if you plan to submit later.
What Test Day Looks Like at Pearson VUE
Knowing the format helps you choose an appointment time that fits your concentration. The initial exam is 120 multiple-choice questions delivered in two 60-question blocks, with 60 minutes allotted per block. The two-hour exam timer excludes a 15-minute tutorial and a 15-minute break, so budget closer to two and a half hours of seat time plus check-in.
- Closed book: personal calculators, notes, and books are prohibited
- No backtracking across blocks: questions in a finished block cannot be revisited
- Fixed pacing: 60 questions in 60 minutes leaves roughly one minute per item
Because you cannot return to a completed block, pacing within each block matters more than usual. Schedule your appointment for the part of the day when you do your sharpest clinical reasoning, and avoid stacking it after a night shift. If you are wondering how demanding that format is in practice, our PA-CN difficulty guide addresses it directly.
Key Takeaway
Since finished blocks are locked, practice in 60-minute, 60-question sets before your appointment. The goal is to rehearse committing to answers, not to simulate unlimited review time.
Score Release and the Award Timeline
Scores generally arrive eight to ten weeks after administration, following validation. That gap is the single most underestimated item in candidates' calendars. If a promotion, contract renewal, or credentialing committee deadline depends on holding the CAQ, work backward from the end of that eight-to-ten-week window, not from your exam day.
The award itself requires a passing specialty-exam result plus completion of the non-exam requirements. Once awarded, the CAQ is valid for ten years while your PA-C and licensure remain current. We have not verified a numeric passing threshold or an official specialty-specific pass rate, so be cautious of any source quoting either. See our discussions of the PA-CN passing score and the PA-CN pass rate for what can and cannot be stated responsibly.
Planning Backward From Your Testing Date
Once you have an appointment in mind, the content weighting should drive which topics you schedule in which weeks. The largest medical content categories are Chronic Kidney Disease at 20%, End-Stage Renal Disease / Dialysis at 17%, Renal Pathophysiology at 14%, and Acute Kidney Injury/Intensive Care Unit Nephrology at 11%. Together they account for 62% of the blueprint, so they deserve the earliest and longest blocks. Note that the issuer's heading for the 20% category is Chronic Kidney Disease; some third-party summaries relabel it, but the NCCPA blueprint is the authority.
Largest-weight domains first
- Chronic Kidney Disease (20%): staging, progression, complications, and long-term management
- End-Stage Renal Disease / Dialysis (17%): modality decisions and complications of dialysis care
Mechanisms and acute care
- Renal Pathophysiology (14%): physiology that underpins every other category
- Acute Kidney Injury/Intensive Care Unit Nephrology (11%): evaluation and management of acute presentations
Mid-weight and smaller domains
- Hypertension (10%)
- Glomerular Disorders (6%) and Systemic Disorders (6%)
- Tubulointerstitial/Viral Disorders (5%) and Kidney Transplantation (5%)
- Vascular Disorders (3%) and Legal/Ethical Issues and Emerging Topics (3%)
Official practice material
- Work the NCCPA Sample Nephrology Questions & Critiques
- Consider the optional $50 NCCPA practice exam: one form, 180-day completion window, educational feedback that does not predict a pass
Remember that the six exam tasks (History and Physical 7%, Diagnostic Studies 20%, Diagnosis 25%, Managing Patients 35%, Applying Scientific Concepts 10%, Legal/Ethical Issues and Emerging Topics 3%) cross-classify the same questions. They are not additional domains and should not be added to the medical-content weights. Managing Patients being the heaviest task is a good reason to practice treatment-decision questions, not only recall. For a fuller preparation plan, see the PA-CN study guide, and for realistic practice questions, use the main practice test site.
Maintenance Exam Windows in Years Nine and Ten
Scheduling does not end with your first pass. The CAQ is valid for ten years, and renewal requires 125 nephrology Category I CME credits earned during the cycle and submitted by the maintenance-exam application, plus passing the specialty examination. Under the May 2026 governing policy, you get three maintenance attempts in years nine and ten.
Maintenance candidates have a choice the initial candidate does not: test-center or online. The online maintenance exam retains 120 questions but allows five minutes per question within an approximately six-week window; references are allowed, while assistance from others is not. These are maintenance-only conditions. There is no initial remote testing option, so do not plan on taking the first attempt from home.
| Feature | Initial Exam | Online Maintenance Exam |
|---|---|---|
| Delivery | Pearson VUE test center | Online, within an approximately six-week window |
| Questions | 120 (two 60-question blocks) | 120 |
| Time | 60 minutes per block | Five minutes per question |
| References | Closed book | Allowed; assistance from others not allowed |
