CHN Exam Dates 2026: Testing Windows, Deadlines & Scheduling

How CHN Scheduling Works (No Fixed Calendar)

If you are searching for a neat list of national test dates for the Certified Hemodialysis Nurse credential, here is the first thing to understand: the verified information for this exam does not describe a single published calendar of fixed national dates. Instead, scheduling is tied to your application, your authorization, and your chosen testing format. That makes "exam dates" less about circling a day on a calendar and more about managing a sequence of steps.

The credential is administered by the Board of Nephrology Examiners Nursing & Technology (BONENT). Candidates test either on paper, under approved onsite proctoring, or by computer through a linked SMT/IQT testing network. Because the exact appointment availability depends on the format you pick and on what the network or proctoring site can offer, the safest approach is to treat the BONENT website as your source of truth for current windows and to build your study plan around your own authorization timeline rather than a rumored date.

This article focuses on what is firmly known: the steps, the formats, the fees, and the rules that shape when you can realistically sit for the exam. For a broader look at eligibility, see our guide to CHN requirements, eligibility, and prerequisites.

Why Authorization Comes Before Any Date

You cannot simply pick a seat and show up. The Certified Hemodialysis Nurse process includes authorization and application deadlines, and your testing date flows from those approvals. In practical terms, the earliest you can test is governed by how quickly you complete the application and have your eligibility confirmed.

Standard eligibility route

• RN pathway: an eligible RN license plus one year of nephrology experience.
• LPN/LVN pathway: an eligible LPN/LVN license plus two years of nephrology experience.
• Active ESRD work: your experience must involve end-stage renal disease care, not just general nursing.
• Two signed references: these must be obtained and submitted with your application.

The alternate training pathway

An approved corresponding nurse-training pathway also exists. It requires BONENT confirmation plus supporting documentation. If you are on this route, build in extra lead time, because confirmation from the board is a prerequisite step that sits outside your control. Candidates on this path should contact BONENT early rather than assuming their program automatically qualifies.

Paper vs. CBT: Choosing Your Format

Format choice is the single biggest lever you have over your scheduling experience. Both formats cover the same 150 multiple-choice questions in a 3-hour window, but they differ in logistics and cost.

One point deserves emphasis: CBT through the linked network is not a verified at-home route. Plan on traveling to an approved testing location. If you are picturing a remote, living-room exam, correct that assumption now so it does not disrupt your planning later.

For international candidates, the fee structure flips the usual logic. The paper exam costs USD 260, while CBT is USD 255, so computer-based testing is slightly cheaper abroad, whereas in the U.S. paper is the lower-cost option. No member versus non-member pricing tiers are published for this exam, so you do not need to hunt for a discount tied to association membership. For the full financial picture, including maintenance costs after you pass, read our CHN certification cost breakdown.

Fees, Expedite Option, and What They Mean for Timing

There is an optional USD 100 expedite fee. This is the only published lever for speeding up processing, and it is worth understanding what it does and does not do.

• What it can help with: moving your application through processing faster once it is complete.
• What it cannot fix: missing documentation, unsigned references, or an eligibility question that BONENT needs to resolve. Expediting an incomplete file does not make it complete.

Budget the expedite fee separately from your exam fee. A candidate choosing U.S. CBT with expedited processing would be looking at the CBT fee plus the additional USD 100, so decide up front whether your timeline warrants it. If you are weighing whether the whole investment makes sense, our ROI analysis of the CHN certification walks through the cost-benefit question.

Planning Backward From Your Exam Date

Since no universal mandatory prep-hour total is verified for this exam, there is no official number telling you how long to study. That means your preparation window is something you set based on your experience, your comfort with each domain, and your authorization timeline. The most reliable way to do that is to plan backward.

1. Confirm eligibility first. Verify your license, nephrology experience duration, and ESRD work against the standard route or the training pathway.
2. Collect your two signed references. Do this before anything else, since they depend on other people's schedules.
3. Submit your application and note any deadline. Authorization and application deadlines apply, so record them the moment you learn them.
4. Choose your format. Decide paper or CBT, factoring in cost, location, and your own test-taking comfort.
5. Anchor your study plan to your authorized testing window. Work backward from the date you actually have, not the date you hope for.

A common mistake is to begin studying intensely before authorization is secured, then lose momentum when paperwork delays push the exam out. A better pattern is to start with light, steady review of the heaviest domain while your application processes, and ramp up intensity once your testing window is confirmed. Our CHN study guide covers resource selection and overall preparation strategy in more depth.

Sequencing Domains Across Your Prep Window

This is the one place where scheduling and study methodology meet, and it matters because the exam is so heavily weighted toward one domain. Dialysis and Related Issues accounts for 74.5% of the exam, which means roughly three out of every four questions come from that single area. Your calendar should reflect that imbalance rather than dividing time equally.

Note that Domain 1 appears under two names depending on the source: the official PDF calls it Supervision/Management, while the website overview refers to it as Supervision/Administration. They describe the same area, so do not be thrown if you see either label on study materials. For a deeper breakdown of what each area tests, see our complete guide to the four CHN exam domains.

Exam-Day Rules That Affect Your Booking

Certain exam-day policies should shape how you prepare and which format you choose, so it pays to know them before you commit to a date.

• Closed book: no notes or study references are permitted during the exam.
• No personal calculators or reference devices: under the linked handbook, you may not bring your own. If the exam presents any calculation, you should be prepared to work it without personal tools.
• Time pressure: 150 questions in 3 hours leaves roughly 72 seconds per question on average, so pacing matters.

Because you cannot lean on outside tools, practice calculation-style questions the way you will face them: by hand and under a timer. Our CHN practice tests are built to help you rehearse that pacing across the full 150-question length. If you want to understand how the numbers on your score report work, our explainer on the CHN passing score clarifies what a scaled 70 does and does not mean.

Accommodations and International Candidates

Accommodations are available for candidates who need them. If you require an accommodation, raise it at the application stage rather than close to your test date, because arrangements may require documentation and additional coordination that can affect timing. Since authorization and application deadlines apply, an accommodation request filed late could force you into a later testing window.

International candidates should note the different fee structure described earlier and should confirm testing-site availability early. Because format availability depends on the approved proctoring arrangement or the SMT/IQT network, what is offered near you may influence whether paper or CBT is realistic. Contact BONENT to confirm options for your region before finalizing your plan.

After You Pass: Validity and Renewal Dates

Scheduling does not end once you pass. The certification is valid for four years, so your next important date is your renewal deadline. Marking it on your calendar from day one prevents a lapse.

Renewal basics

• Standard renewal: 40 contact hours, including at least 30 nephrology hours.
• Alternative routes: a qualifying examination route or a once-in-lifetime waiver route.
• Maintenance fees: USD 65 annually, or USD 240 prepaid for four years.

The prepaid option costs USD 240 for four years versus USD 260 if you pay USD 65 each year, so prepaying saves USD 20 over the full cycle. Spread your contact hours across the four years rather than cramming them into the final months. Note also that a 2026 renewal booklet exists, but it is not an exam-version update, so do not mistake renewal materials for a change to the test itself.

Passing also opens doors in the job market; see our overview of CHN jobs and our CHN salary guide for what to expect as you plan your career timeline.
