What "RNAS-C Training" Actually Covers
When nurses search for RNAS-C training, they usually mean one of two different things, and mixing them up leads to wasted months. The first is the clinical and educational pathway that makes you eligible to sit for the Registered Nurse Assistant at Surgery - Certified examination at all. The second is the focused preparation you do to pass the 150-question test administered through the National Assistant at Surgery Certification (NASC).
This article treats both. The credential is for registered nurses who work as first assistants in the operating room, and certification is not something you can reach through coursework alone. It rests on documented, hands-on intraoperative experience, a formal RNFA-program completion, and professional endorsements. If you are still sorting out the basics of the credential itself, start with What Is RNAS-C Certification? and then return here for the training roadmap.
Training Pathway: Program, Hours, and Credentials
Eligibility for the RNAS-C is built from several separate requirements. Each one has its own training implication, so it helps to see them as a checklist rather than a single hurdle.
| Requirement | What It Means for Your Training |
|---|---|
| Current unrestricted RN license | Must be held in the country where you practice; any restriction on the license is a problem to resolve first. |
| ACLS, BLS, or CPR certification | One current certification is required; keep it from lapsing during the application window. |
| Formal RNFA-program completion | The program must be acceptable to the certifying body; confirm before you enroll. |
| 120 intraoperative first-assisting hours | Must fall within the preceding two years and be documented. |
| CNOR (non-APRN applicants) | Perioperative nursing certification is a prerequisite for non-APRN candidates. |
| APRN certification (APRNs) | APRNs use accredited APRN certification instead of the CNOR route. |
| Two recommendations | One from a surgeon and one from an operating-room supervisor or manager. |
A bachelor's degree is not required, which opens the credential to experienced RNs who advanced through diploma or associate-degree routes. For the full eligibility picture, including edge cases, see RNAS-C Requirements 2026: Eligibility, Prerequisites & How to Qualify.
Why the CNOR Matters to Your Timeline
For non-APRN applicants, holding a current CNOR is not optional, so if you do not already have it, that credential becomes the first stage of your training plan. Build the CNOR into your timeline early, because it sits upstream of everything else and the RNAS-C application cannot proceed without it.
Choosing a Program Wisely
The formal RNFA-program requirement means the program you select needs to be acceptable to the certifying body. Before paying tuition, confirm acceptability directly with NASC rather than relying on a program's marketing language. A program with a strong clinical-placement component also helps with the hours requirement, which brings us to the next point.
The Exam You Are Training For
Knowing the test's mechanics shapes how you should practice. The RNAS-C is a live, remote-proctored examination delivered through Prolydian.
- Length: 150 multiple-choice questions.
- Question style: four answer choices, one correct answer.
- Time: three hours total, with one optional 15-minute break.
- Extensions: no established extension of the examination allowance.
- Passing score: 70%, which is a cut score rather than a pass-rate statistic.
- Results: reported within 72 hours.
Three hours for 150 questions works out to roughly 72 seconds per question if you used every minute on the questions alone. That pacing is workable for recall items but tight for case-based items, so timed practice matters. For a frank look at what makes the test demanding, read How Hard Is the RNAS-C Exam? Complete Difficulty Guide 2026, and for the scoring threshold itself see RNAS-C Passing Score 2026: Exactly What You Need to Pass.
Training by Content Section
The official study guide organizes the exam into five weighted sections. These are examination content headings, not a curriculum designed for teaching, so treat them as the blueprint your training must eventually map onto. A deeper walkthrough lives in RNAS-C Exam Domains 2026: Complete Guide to All 5 Content Areas; here is how each section translates into training priorities.
Domain 1: Surgical Patient Care (22%)
This section ties for the largest allocation. Your daily practice as a first assistant in the OR is the best training ground, because patient care in the surgical setting is something you do, not just recall.
- Connect each bedside or tableside action to the reasoning behind it.
- Review patient safety principles as they apply during an operation.
- Practice articulating why you would act, not only what you would do.
Domain 2: Surgical Skill (22%)
The study guide's formal wording is "Surgical Skill" in the PDF, while the issuer's current web page uses "Surgical Skills." The weight is the same either way. This is where your logged intraoperative hours pay off.
- Reflect on the technical tasks you perform as first assistant.
- Use cases from your own hours to anchor abstract questions.
- Ask your supervising surgeon to explain technique choices you only partly understand.
Domain 3: Anatomy & Physiology (22%)
This is the most book-driven of the large sections, and it is where experienced OR nurses often discover gaps. Familiarity with a procedure is not the same as being able to answer a structured anatomy question.
- Review anatomy in the context of operative approaches.
- Link physiology to what happens when structures are disrupted or repaired.
- Close gaps in systems you rarely encounter in your usual service line.
Domain 4: Procedure Considerations (22%)
This section rewards breadth. If your daily work concentrates in one specialty, your preparation needs to reach beyond it.
- Study procedures outside your usual service line.
- Think through the sequence and decision points of common operations.
- Notice where considerations differ between similar procedures.
Domain 5: Pre- and Postoperative Considerations (12%)
At 12%, this is the smallest allocation, but the weight does not make it ignorable. The official guide verifies the heading and weight without a detailed objective list, so avoid assuming specific subtopics that the issuer has not published.
- Review the continuum of care before and after the operating room.
- Do not over-invest here at the expense of the four 22% sections.
- Use practice questions to discover which angles are actually tested.
Key Takeaway
Four sections each hold 22%, which together account for 88% of the exam. Allocate your effort accordingly, and keep Pre- and Postoperative Considerations in view without letting it consume your calendar.
Which Hours Count Toward the 120
The hours rule trips up more applicants than any content question. The requirement is 120 documented intraoperative first-assisting hours in the two years before you apply. Eligible internship or practicum hours count toward that total. Classroom hours and seminar hours do not.
That distinction has direct training consequences:
- Log as you go. Reconstructing hours from memory months later is unreliable and difficult to verify.
- Separate categories. Keep intraoperative first-assisting time distinct from didactic time in your records.
- Mind the window. Hours must fall within the preceding two years, so older experience may age out before you apply.
- Secure your endorsers early. The surgeon and the OR supervisor or manager who write your recommendations should be people who have observed your work.
Sequencing Your Preparation Around the Weights
Once you meet eligibility, preparation should follow the exam blueprint. Because the application triggers a four-month window to test, you will want a plan that fits inside it. The sequence below is one reasonable ordering tied to the RNAS-C sections, not an issuer requirement.
Anatomy & Physiology first
- Target the gaps outside your usual surgical specialty.
- Anatomy underlies questions in other sections, so it pays forward.
Procedure Considerations and Surgical Skill
- Work through procedures beyond your daily service line.
- Tie technique questions to cases you have actually assisted on.
Surgical Patient Care, then Pre- and Postoperative Considerations
- Give the 22% patient-care section real depth.
- Cover the 12% section efficiently, guided by practice-question results.
Timed full-length rehearsal
- Simulate 150 questions in a single three-hour sitting.
- Review misses by section to decide where final days go.
For a broader preparation framework, including how to review mistakes, see RNAS-C Study Guide 2026: How to Pass on Your First Attempt. When you want a quick condensed refresher near test day, the RNAS-C Cheat Sheet 2026 collects the must-know facts in one place. You can also drill questions at the main practice test site to pressure-test each section as you finish it.
Registration, Fees, and Retake Rules
Training ends in a scheduled appointment, so understand the logistics before you commit.
| Item | Detail |
|---|---|
| Initial examination fee | USD 425 |
| Retake fee | USD 195 |
| Testing window | Within four months of application |
| Rescheduling | At least four hours before the appointment |
| Results | Within 72 hours |
| First retake timing | 45 to 90 days after the original exam |
| Attempt limit | Maximum three attempts in 12 months |
The retake spacing is worth planning around. If your first attempt does not go as hoped, you cannot immediately rebook; the 45-to-90-day interval is itself a built-in training period, and a diagnostic review of your weakest sections is the best use of it. For the full financial picture beyond exam fees, see RNAS-C Certification Cost 2026: Complete Pricing Breakdown, and for scheduling specifics see RNAS-C Exam Dates 2026: Testing Windows, Deadlines & Scheduling.
Training Never Fully Ends: Recertification
The credential lasts three years, and the requirements for renewing it were updated on August 6, 2025. Treating recertification as a continuing form of training keeps you from being surprised.
- Maintain your RN licensure and BLS.
- Document 300 RNFA practice hours, including 250 intraoperative hours.
- Choose one route: earn 240 points with a USD 275 fee, or pass the recertification examination for USD 325.
One detail catches people off guard: the points route does not equate points with CE hours. The 300 required practice hours contribute 30 of the 240 points, and one CE or CME hour earns two points. Plan your continuing education with that conversion in mind rather than assuming a one-to-one relationship.

Frequently Asked Questions
No. Eligible internship or practicum hours count, but classroom and seminar hours do not. The 120 hours must be documented intraoperative first-assisting time within the preceding two years.
Non-APRN applicants require a current CNOR. APRNs use accredited APRN certification instead. Both routes also require recommendations from a surgeon and an operating-room supervisor or manager.
No. A bachelor's degree is not required. You do need a current unrestricted RN license, a current ACLS, BLS, or CPR certification, and acceptable formal RNFA-program completion.
You may attempt it a maximum of three times in 12 months. The first retake must be 45 to 90 days after the original examination, and a retake costs USD 195.
No. The RNAS-C is a surgical first-assisting certification, not initial RN licensure. Its content centers on five weighted sections, from Surgical Patient Care through Pre- and Postoperative Considerations, rather than the NCLEX-RN blueprint.
