PA-CN Certification Cost 2026: Complete Pricing Breakdown

TL;DR
  • NCCPA's initial Nephrology CAQ exam costs $350 total: $100 registration/administration plus $250 for the examination.
  • The optional NCCPA practice exam costs $50, offers one form, and must be completed within 180 days.
  • You need 75 nephrology-focused Category I CME credits, with at least 25 earned in the preceding two years.
  • Eligibility requires 4,000 total PA practice hours, including at least 2,000 in nephrology, not 4,000 nephrology hours.

What You're Actually Paying For

"PA-CN" is the shorthand used on this site for the Certificate of Added Qualifications in Nephrology, a specialty credential awarded by the National Commission on Certification of Physician Assistants (NCCPA). Successful candidates earn the designation PA-C, CAQ-Neph. It is a PA specialty CAQ layered on top of your existing PA-C. It is not initial PA certification, a nephrology nursing credential, or a physician nephrology-board examination. If you need a refresher on the credential itself, see What Is PA-CN Certification? and the overview at PA-CN Certification.

When people ask what the certification costs, they usually mean the exam fee. That is the smallest and most predictable line item. The larger costs are the continuing education you must accumulate, the practice hours you must document, the preparation resources you choose, and the cost of maintaining the credential across a ten-year cycle. This guide separates what is fixed and published from what depends on your own choices, so you can build a budget without guessing.

A note on numbers: Only fees published by NCCPA are stated here as figures. CME prices, employer reimbursement, travel to a test center, and commercial prep products vary widely, so those are described qualitatively rather than with invented dollar amounts. Always confirm current fees on the NCCPA site before paying.

The NCCPA Exam Fee, Line by Line

The initial exam fee is $350 in total. NCCPA splits it into two components:

ComponentAmountWhat It Covers
Registration/administration$100Processing your CAQ application and administrative handling
Examination$250The 120-question Nephrology CAQ exam delivered at a Pearson VUE test center
Total$350Initial exam pathway

The exam itself is 120 multiple-choice questions split into two 60-question blocks, with 60 minutes per block. The two-hour timer does not include a 15-minute tutorial or a 15-minute break. Testing is closed book, and personal calculators, notes, and books are prohibited. Questions in a finished block cannot be revisited, which is a format detail worth practicing against because it changes how you spend time on hard items.

Initial testing takes place at Pearson VUE test centers. There is no remote option for the initial exam, so you should factor in any travel, parking, or time off work associated with reaching a center. Scheduling windows and deadlines are covered in PA-CN Exam Dates 2026.

The Biggest Cost: 75 Nephrology CME Credits

Before you can apply, you need 75 nephrology-focused Category I CME credits earned within the six years before your exam application, including at least 25 in the preceding two years. For many working PAs, a good portion of these credits accumulate through normal professional activity: nephrology conferences, society meetings, hospital grand rounds that carry Category I credit, and online courses. The real cost depends entirely on how you earn them.

Three realities shape this line item:

  • Employer CME allowances. Many PAs have an annual CME budget. If yours covers nephrology-relevant activities, much of the 75-credit requirement may cost you nothing out of pocket.
  • The nephrology focus requirement. General primary-care credits do not count toward the 75. If your practice is mixed, you may need to deliberately choose nephrology-specific programming.
  • The recency rule. At least 25 credits must fall in the preceding two years, so a stockpile of older credits alone will not satisfy the requirement.
Budgeting tip: Audit your existing CME transcript first. Credits you already earned in nephrology within the six-year window may cover most or all of the requirement, which turns this from a new expense into a documentation task.

ACLS is recommended rather than an additional mandatory course, so you do not need to add a certification fee there. For the full eligibility picture, read PA-CN Requirements 2026.

Practice Exam and Preparation Spending

The Official NCCPA Practice Exam: $50

NCCPA offers an optional practice exam for the Nephrology CAQ at $50. NCCPA lists one practice form for this specialty, with a 180-day completion window. The feedback is educational, and NCCPA is clear that it does not predict whether you will pass the real exam. Think of it as a format familiarization tool and a way to surface weak domains, not a score forecast. It is the only practice product with the issuer's name on it, which is why many candidates treat it as a baseline purchase.

Free Official Material

NCCPA publishes a free Content Blueprint for the Nephrology CAQ Examination (three pages) and a document of Sample Nephrology Questions & Critiques (copyright 2024). Both cost nothing and should be the first items in your prep stack. The blueprint tells you how the exam is weighted; the sample questions show you how items are written and critiqued. For a detailed walkthrough of the weighting, see PA-CN Exam Domains 2026: Complete Guide to All 11 Content Areas.

Commercial Prep: Spend Deliberately

Commercial question banks, review courses, and nephrology texts are optional and priced independently. A sensible approach is to buy only after you have taken stock of your weak areas. Be cautious about any product that promises a guaranteed pass: no official specialty-specific pass rate or numeric passing threshold has been verified, so guarantees cannot be grounded in published data. For what is and is not known, see PA-CN Pass Rate 2026 and PA-CN Passing Score 2026. If you want a free place to drill questions alongside paid resources, the main practice test site is available.

Time, Hours, and Attestation Costs

Not every cost is cash. The experience requirement is a significant time investment, and misreading it is a common mistake. You need 4,000 total hours of PA practice, including at least 2,000 hours in nephrology, within the six years before you attest that the experience requirement has been satisfied. The requirement is not 4,000 nephrology hours. A PA with several years in a nephrology practice will typically have satisfied this simply by working.

You also need an attestation from a collaborating physician or a lead/senior PA who works in nephrology and knows your practice. A physician or PA postgraduate program director may sign for a PA enrolled in or graduated from that program. Key mechanics that affect your budget and timeline:

  • The attestation may be submitted before the exam or within 90 days after score notification.
  • The form addresses relevant knowledge and performance, including management within at least one listed setting: end-stage renal disease, chronic kidney disease, kidney transplantation, or acute inpatient dialysis.
  • There is no separate timed practical assessment, and you do not need to work in every nephrology subspecialty.

Signing the attestation does not carry a published fee in the NCCPA materials, but the indirect cost is the relationship: you need a supervisor who knows your work well enough to sign. PAs changing jobs should lock this down before leaving a nephrology practice.

You must also hold a current PA-C and unrestricted U.S. PA licensure (or unrestricted government-agency practice privileges), with all held licenses unrestricted. Keeping your base PA-C certification and licenses current is an ongoing cost you are already paying, but a lapse would block the CAQ entirely.

Timeline Risk and Repeat-Attempt Planning

The initial CAQ process must be completed within six years after initiation. That window is generous, but it matters for budgeting: if your first attempt does not go as planned, a repeat attempt means returning to the fee structure for another sitting. This guide does not state a repeat-attempt fee because it was not verified in the source material, so check NCCPA's current fee schedule before planning a retake.

Scores generally arrive eight to ten weeks after administration following validation. The award requires a passing specialty-exam result and completion of the non-exam requirements, so your attestation and CME documentation should be squared away before or shortly after testing to avoid delays in receiving the credential.

Key Takeaway

The cheapest way to pay for this certification is to pass the first time. Spend your preparation budget where the exam is weighted, and use the free blueprint and the $50 practice exam to find gaps before you pay the $350 exam fee.

Keeping the CAQ: Ten-Year Maintenance Costs

The CAQ is valid for ten years as long as your PA-C and licensure remain current. Renewal is where the long-term cost sits. You need 125 nephrology Category I CME credits earned during the cycle and submitted by the maintenance-exam application, plus a passing score on the specialty examination. Older 150-credit summaries circulating online are not adopted here; use the current NCCPA policy.

Maintenance exam mechanics worth knowing:

  • The May 2026 governing policy allows three maintenance attempts in years nine and ten.
  • Maintenance can be taken at a test center or online.
  • The online maintenance exam keeps 120 questions but allows five minutes per question within an approximately six-week window. References are allowed; assistance from others is not.
  • These online conditions apply to maintenance only. They are not an option for initial testing.
Policy conflict to verify: The May 2026 governing policy says passing before year nine resets the cycle, while the online-maintenance policy says before year ten. If your plan depends on a ninth-year pass, get written confirmation from NCCPA about the cycle effect rather than assuming either version.

Spreading 125 credits over ten years works out to a steady annual pace rather than a lump sum, which makes it easier to absorb through an employer CME allowance. The maintenance exam fee itself is not stated in the facts used for this article, so check NCCPA directly when you approach the renewal window.

Where Study Dollars Should Go, by Domain

If you are paying for prep, allocate it to match how the exam is weighted. The medical content categories are official NCCPA headings, and the largest ones deserve the most attention:

Chronic Kidney Disease (20%)

The single largest category. Any paid resource you buy should cover CKD thoroughly, since it carries more weight than any other content area.

End-Stage Renal Disease / Dialysis (17%)

The second-largest category. Note that NCCPA's heading for the 20% category is Chronic Kidney Disease; a third-party summary labels it differently, so rely on the issuer's wording when evaluating a prep product's outline.

Renal Pathophysiology (14%)

A foundational category that supports reasoning across many other questions. Resources strong in mechanisms offer good value here.

Acute Kidney Injury/Intensive Care Unit Nephrology (11%)

Relevant for PAs in inpatient and critical-care nephrology settings, and worth extra focus if your daily practice is outpatient.

The remaining categories are Hypertension (10%), Glomerular Disorders (6%), Systemic Disorders (6%), Tubulointerstitial/Viral Disorders (5%), Kidney Transplantation (5%), Vascular Disorders (3%), and Legal/Ethical Issues and Emerging Topics (3%). A separate task-based classification (History and Physical 7%, Diagnostic Studies 20%, Diagnosis 25%, Managing Patients 35%, Applying Scientific Concepts 10%, Legal/Ethical Issues and Emerging Topics 3%) cross-classifies the same exam. Those task weights are not extra domains and should not be added to the content weights.

A Weighted Way to Sequence Your Prep

If you do buy materials, schedule them against the weights rather than evenly. One reasonable sequence:

Weeks 1-2

Chronic Kidney Disease and Hypertension

  • Cover the largest category first, then pair it with Hypertension (10%) because the two overlap clinically
  • Work through the free NCCPA sample questions and critiques
Weeks 3-4

ESRD/Dialysis and Renal Pathophysiology

  • Study dialysis management and the mechanisms that underlie it
  • Use pathophysiology to explain why management choices work
Weeks 5-6

AKI/ICU Nephrology and the Smaller Domains

  • Cover glomerular, systemic, tubulointerstitial, transplant, and vascular topics
  • Take the $50 NCCPA practice exam, then target the gaps it reveals

Weighing the Return

Whether the total outlay is worthwhile depends on your career goals, employer, and practice setting. This article does not assume that the certification causes a pay premium, and no CAQ-specific salary figures are used here. For a measured look at that question, see Is the PA-CN Certification Worth It? and PA-CN Salary Guide 2026. If you are exploring where nephrology PAs work, PA-CN Jobs covers the employment side.

Frequently Asked Questions

How much does the Nephrology CAQ exam cost in total?

The initial exam costs $350 total, made up of a $100 registration/administration fee and a $250 examination fee. Adding the optional $50 NCCPA practice exam brings the fixed NCCPA cost to $400. CME, travel, and commercial prep are additional and vary.

Is the NCCPA practice exam worth $50?

It is a low-cost way to experience the format and identify weak domains. NCCPA lists one practice form with a 180-day completion window, and states that the feedback is educational and does not predict an exam pass, so treat it as diagnostic rather than as a score predictor.

Do I need 4,000 hours of nephrology experience?

No. You need 4,000 total hours of PA practice, of which at least 2,000 must be in nephrology, within six years before you attest that the experience requirement has been satisfied. Misreading this as 4,000 nephrology hours is a common error.

What are the ongoing costs after I earn the CAQ?

The CAQ is valid for ten years while your PA-C and licensure stay current. Renewal requires 125 nephrology Category I CME credits earned during the cycle plus passing the specialty exam. Maintenance may be taken at a test center or online, and the exam fee for maintenance should be confirmed with NCCPA.

Can I take the initial exam from home to save on travel?

No. Initial testing is delivered at Pearson VUE test centers. The online format, with five minutes per question and open references, applies only to the maintenance exam, not to initial certification.

The published cost of the Nephrology CAQ is modest compared with the effort behind it: $350 for the exam, an optional $50 for practice, and a ten-year commitment to nephrology CME. Verify every fee with NCCPA before you pay, document your hours and credits early, and put your preparation money where the blueprint puts its weight. When you are ready to drill questions, head to the practice test site.
