RNAS-C Exam Dates 2026: Testing Windows, Deadlines & Scheduling

Why the RNAS-C Has No Fixed Exam Calendar

If you are searching for a list of national test dates for the Registered Nurse Assistant at Surgery - Certified (RNAS-C) credential, the answer may surprise you: the process is built around your application date, not a published calendar of seasonal windows. The National Assistant at Surgery Certification (NASC) administers the exam as a live, remote-proctored examination delivered through Prolydian. Instead of waiting for a spring or fall sitting, candidates apply, are approved, and then schedule an appointment within a defined period.

That structure changes how you plan. The question is not "which date should I circle on the 2026 calendar?" but "when will my application be complete, and how much preparation can I finish before my four-month window closes?" This article walks through each timing rule that governs the RNAS-C, from the moment you begin gathering documentation to the day you receive your result and, eventually, the day you recertify.

The Clock Starts With Eligibility, Not Scheduling

Most candidates underestimate how much of the "exam timeline" happens before they ever see a scheduling screen. The RNAS-C is a surgical first-assisting credential, so eligibility is substantial and documentation-heavy. You cannot simply register and test. Before NASC will approve you to schedule, you need to assemble several pieces:

• A current, unrestricted RN license in your country of practice.
• Current ACLS, BLS, or CPR certification.
• Acceptable formal RNFA-program completion.
• 120 documented intraoperative first-assisting hours within the preceding two years. Eligible internship or practicum hours count; classroom and seminar hours do not.
• Current CNOR for non-APRN applicants, while APRNs use accredited APRN certification instead.
• Recommendations from both a surgeon and an operating-room supervisor or manager.

A bachelor's degree is not required. The practical consequence for timing is that the slowest part of your journey is usually not the exam booking but the paperwork: collecting the surgeon's recommendation, getting the OR supervisor or manager to complete theirs, and documenting hours that fall inside the two-year lookback. If your 120 hours were logged long ago, some may age out of the window before you apply. For a full breakdown of each prerequisite, see our guide to RNAS-C requirements, eligibility and how to qualify.

The Four-Month Testing Window

The single most important date rule for the RNAS-C is this: you must test within four months of your application. That window is your effective deadline. It is the reason the application date matters more than any calendar month.

Think of it as a countdown that starts the day you apply:

1. You submit your application with supporting documentation.
2. NASC reviews and approves your eligibility.
3. You schedule a live remote-proctored appointment through Prolydian.
4. You sit the exam before the four-month period ends.

Because the exam is delivered remotely rather than at a limited number of physical test centers, scheduling flexibility is generally greater than with exams tied to fixed seasonal sittings. But flexibility is not unlimited: you still need an appointment slot, a compliant testing environment, and enough preparation completed to be ready. Applying and then letting weeks slip by is the fastest way to squeeze your study time.

To judge how much preparation you realistically need before you apply, read our assessment of how hard the RNAS-C exam is.

What You Are Scheduling: Format and Fees

Knowing exactly what the appointment involves helps you choose a sensible time of day and prepare your space. The RNAS-C is a single-sitting, multiple-choice exam with the following characteristics:

A few scheduling implications follow directly from this table. Three hours for 150 questions works out to roughly 72 seconds per question on average, so you want to book a time when you are mentally sharp and uninterrupted. Because the optional break is only 15 minutes and there is no established extension, plan meals, hydration, and your workspace in advance. For a closer look at the score threshold itself, see our article on the RNAS-C passing score, and note that 70% is a passing score, not a pass-rate statistic. If you want the data picture, our RNAS-C pass rate article covers what can and cannot be said. For full pricing context beyond the exam fee, see the RNAS-C certification cost breakdown.

Choosing a time of day

Since the exam is live-proctored remotely, you generally have more control over your testing environment than candidates at a distant testing center. Use that to your advantage: pick the part of the day when your first-assisting reasoning is sharpest, silence notifications, and make sure the room, equipment, and connectivity requirements outlined by the proctoring service are met well before the appointment.

Rescheduling and the Four-Hour Rule

Life in the operating room is unpredictable, and NASC builds in a rescheduling provision: you must reschedule at least four hours before your appointment. That is a short cutoff compared with some testing programs, but it is a hard one. Miss it and you risk forfeiting the appointment rather than moving it.

Treat the four-hour rule as a decision deadline, not a courtesy:

• If you are on call or may be pulled into a case, check your surgical schedule before you book.
• If you wake up unwell or clearly underprepared, decide early enough to act before the cutoff.
• Remember the four-month window still applies, so rescheduling late in your window leaves little room to maneuver.

Because rescheduling consumes some of your remaining window, avoid booking your first appointment at the very end of the four months. Leaving a buffer lets you move the appointment once, if needed, without losing the chance to test under your original application.

Retake Timing: The 45-to-90-Day Rule

If your first attempt does not result in a pass, the retake schedule is tightly structured. The first retake must fall 45 to 90 days after the original examination. There is also a cap: a maximum of three attempts in 12 months. The retake fee is USD 195.

Those two constraints define a deliberate recovery period. You cannot immediately re-sit the exam to try again the next week, and you cannot run an unlimited number of attempts in a year. The 45-day minimum forces a genuine gap for focused remediation; the 90-day upper bound keeps your retake from drifting indefinitely.

A retake plan keyed to the content sections

Because your performance is organized around five weighted content sections, a retake plan should be too. Four of the five sections, Surgical Patient Care, Surgical Skill, Anatomy & Physiology, and Procedure Considerations, each carry 22%. Pre- and Postoperative Considerations carries 12%. If you fell short, ask which of the 22% sections consumed the most of your uncertainty, and give those the heaviest share of your 45-plus days. Our complete guide to all five RNAS-C content areas breaks each section down in detail.

Recertification Timing and the 2026 Transition

Passing the exam is not the end of your timeline. RNAS-C certification runs for three years, and recertification has its own requirements and dates. NASC updated the recertification requirements on August 6, 2025, so anyone planning a recertification cycle should read the current rules rather than rely on older guidance.

What recertification now requires

• Maintain your RN licensure and BLS certification.
• Document 300 RNFA practice hours, including 250 intraoperative hours.
• Choose one of two paths: earn 240 points and pay a USD 275 fee, or pass the recertification examination for USD 325.

One detail trips up many candidates: points are not the same as CE hours. The 300 required practice hours contribute 30 of the 240 points, and one CE or CME hour earns two points. That means you cannot simply count continuing education hours one-for-one toward the points total. Plan your recertification activity in points from the start.

The takeaway for timing is simple: if your three-year certification is nearing its end during 2026, confirm with NASC which application and which rule set applies to you before you start collecting documentation. Choosing the wrong path could cost you time you do not have.

Building a Timeline Around the Domain Weights

Since the four-month window gives you a defined runway, it helps to map your preparation against the five weighted content sections instead of studying everything at equal intensity. The weights tell you where your points live: four sections at 22% each and one at 12%. Here is an illustrative way to sequence those sections across the period before your appointment. It is a planning sketch, not an official curriculum.

The logic of this ordering is that anatomy and procedures reinforce each other, and placing the smaller Pre- and Postoperative section late keeps it fresh without overinvesting. Notably, the official study guide verifies the fifth heading and its 12% weight but supplies no detailed objective list for it, so treat your preparation there as reinforcement of general perioperative knowledge rather than a checklist of officially enumerated topics. For a deeper strategy, see our RNAS-C study guide for passing on your first attempt, and when you want quick-hit reinforcement near the end of your window, the RNAS-C cheat sheet condenses the must-know facts onto a single page.

Realistic, timed practice matters most in the final stretch. Working through questions that mirror the four-choice, single-best-answer style helps you build the pacing you will need over three hours. You can build that rhythm with the practice questions on our main practice test site.
