- AS-C stands for Assistant at Surgery - Certified, a surgical first-assistant credential issued by NASC.
- NASC does not currently administer the AS-C exam to new applicants - this is a recertification-era credential.
- Existing AS-C holders maintain credential status through a points system or by examination.
- RNAS-C is a separate, active, exam-based NASC nursing credential - not another name for AS-C.
What Is AS-C?
AS-C stands for Assistant at Surgery - Certified. It is a surgical first-assistant credential administered by the National Assistant at Surgery Certification (NASC) organization. The credential identifies practitioners who have demonstrated competency in first-assisting duties during surgical procedures - tasks like tissue handling, hemostasis assistance, wound closure support, and intraoperative coordination alongside the operating surgeon.
If you've landed here searching for "AS-C," it's worth knowing that the same three letters are used by a handful of unrelated credentials in other fields. This site, and this article, deal exclusively with Assistant at Surgery - Certified as issued by NASC. If you want a deeper dive purely on terminology and how the letters map to the credential, see AS-C Meaning and What Does AS-C Stand For?
Who Holds the AS-C Credential
AS-C holders are typically surgical first assistants who work chairside in the operating room, supporting surgeons across general surgery, orthopedics, cardiovascular procedures, and other specialties. Employers of surgical first assistants generally include hospitals, ambulatory surgical centers, and surgeon group practices that value a documented, credential-based demonstration of first-assisting competency.
Because NASC does not currently open new AS-C exam registration, most people encountering the credential today fall into one of two groups:
- Existing AS-C holders who need to maintain their status through recertification.
- Employers, recruiters, or colleagues trying to verify what an AS-C credential on a résumé actually represents.
If you're evaluating job postings or credential requirements and want a broader look at how AS-C fits into the surgical-assisting job market, AS-C Jobs covers how the credential is referenced in hiring contexts.
Current Status: Why AS-C Is a Recertification-Focused Credential
This is the single most important fact to understand about AS-C in 2026: NASC does not currently administer the AS-C examination to new applicants. In other words, you cannot sit for a first-time AS-C exam right now the way you might for other active first-assistant credentials. The credential is not "closed" in the sense of being discontinued - it continues to exist and be recognized - but new candidate registration is not currently open.
This matters enormously for how you should approach any content, review material, or exam-prep resource labeled "AS-C." Anything positioned as helping a brand-new candidate register and sit for an initial AS-C exam is describing a pathway that isn't currently available. The relevant, accurate use case for AS-C review material today is:
- Existing AS-C holders preparing to recertify, whether by points or by examination.
- Professionals confirming what the AS-C credential covers so they can accurately represent it or compare it to other pathways.
- Employers and credentialing staff verifying what an AS-C designation means on a candidate's file.
Key Takeaway
If you already hold AS-C, your focus should be on recertification - not on searching for "how to register" pages that no longer apply to new applicants.
AS-C vs. RNAS-C, CRNFA, and Similarly Named Credentials
NASC oversees more than one credential, and it's easy to mix them up because the abbreviations look alike. Here's how they differ:
| Credential | Full Name | Current Status | Pathway Type |
|---|---|---|---|
| AS-C | Assistant at Surgery - Certified | Not open to new applicants; existing holders recertify | Points system or recertification exam |
| RNAS-C | Registered Nurse Assistant at Surgery - Certified | Active, exam-based | Initial examination for eligible RN candidates |
| CRNFA | Certified RN First Assistant (NASC-administered) | Active via portfolio | Professional portfolio review (exam discontinued end of 2020) |
It's also worth noting that AS-C is distinct from the differently ordered SA-C abbreviation and from CSFA (a separate first-assistant credential from a different certifying body). If your research keeps surfacing conflicting details about exam fees, question counts, or renewal cycles, you may be looking at information for one of these other credentials rather than AS-C itself. For a focused explainer on the letters alone, see What Does AS-C Mean? and What Is A AS-C?
Recertification Pathways for Existing AS-C Holders
For practitioners who already hold the AS-C credential, NASC provides two ways to maintain certification:
Points System
Existing AS-C holders can accumulate qualifying points over a recertification cycle to maintain their credential without retesting. This typically rewards continued professional engagement in surgical first-assisting practice and related educational activity.
- Best suited for holders who remain actively practicing and can document ongoing professional development.
- Avoids the need to sit for a formal exam again.
Recertification by Examination
Holders who prefer, or need, to demonstrate current competency through testing can recertify by taking the AS-C examination again rather than accumulating points.
- Useful if a lapse in points-eligible activity has occurred.
- Requires refreshing knowledge across the same surgical first-assisting competencies the original credential was built on.
Because the exact structure of the recertification exam draws on the same foundational surgical first-assisting knowledge base as the original credential, reviewing core content is still valuable - it's simply framed around maintaining a credential you already earned rather than earning it for the first time. For a broader sense of how demanding this kind of review can be, How Hard Is the AS-C Exam? Complete Difficulty Guide 2026 discusses the factors that make surgical-assisting exam content challenging.
What to Review Before Recertifying
Whether you're recertifying by points (and want to stay sharp clinically) or by examination (and need to actively prepare), the underlying knowledge base for AS-C centers on surgical first-assisting practice: preoperative preparation, intraoperative assistance technique, hemostasis and tissue handling, wound closure, and postoperative considerations relevant to the assisting role. Because NASC has not published a new-candidate exam blueprint during this recertification-only period, candidates should treat any domain breakdown as a review framework rather than a live registration guide.
A structured review plan still helps organize your time, even for recertification. Rather than generic study advice, tie your review weeks to the areas most likely to appear on a recertification exam based on your own clinical gaps:
Foundational Review
- Revisit surgical first-assisting fundamentals you haven't used recently in daily practice.
- Identify any procedure types you've had less recent exposure to.
Targeted Practice
- Work through practice questions focused on weaker clinical areas.
- Cross-check your recall against current surgical assisting standards.
Full Review Pass
- Simulate exam-style question sets under timed conditions.
- Confirm your recertification paperwork and points documentation are in order alongside your study prep.

How AS-C Compares for Career Planning
Because AS-C isn't currently accepting new applicants, anyone evaluating a first-assistant career path should understand where it fits relative to active options like RNAS-C.

Frequently Asked Questions
Not currently. NASC does not administer the AS-C examination to new applicants right now. The active pathways available today for new candidates are different NASC credentials, such as RNAS-C.
Existing AS-C holders can recertify either through a points system, by accumulating qualifying professional activity, or by taking the recertification examination directly.
No. RNAS-C (Registered Nurse Assistant at Surgery - Certified) is a separate, active, examination-based NASC credential for registered nurses. It has its own eligibility rules, exam format, and fees distinct from AS-C.
NASC's CRNFA credential moved to a professional portfolio pathway. Its former examination was discontinued at the end of 2020, so current CRNFA candidates are evaluated through portfolio review rather than testing.
You can work through timed, exam-style practice sets on our practice test platform to review core surgical first-assisting knowledge ahead of a recertification exam, alongside resources like the AS-C Exam Domains 2026 guide for structured topic review.
