- CSFA training requires graduation from a CAAHEP-accredited Surgical First Assistant program before you can sit for the exam.
- The exam has 175 questions (150 scored, 25 pretest) with a 4-hour limit and a passing score of 99 correct.
- Perioperative Care makes up 55% of the exam, so training time should skew heavily toward intraoperative procedures.
- Exam fees run $240 for AST members and $350 for everyone else, through NBSTSA with PSI as the testing provider.
What CSFA Training Actually Means
"CSFA training" refers to two distinct but connected phases: the formal academic program that qualifies you to sit for the Certified Surgical First Assistant exam, and the targeted exam-preparation work that follows it. The National Board of Surgical Technology and Surgical Assisting (NBSTSA) governs the credential, and it does not allow candidates to challenge the exam through work experience alone. You must be a graduate of a CAAHEP-accredited Surgical First Assistant program. That single prerequisite shapes everything else about how training is structured for this credential.
If you're still getting oriented to the basics of the role, our overview on What Is CSFA? and the plain-language breakdown of CSFA Meaning are good starting points before diving into program specifics.
Program Prerequisites and Accreditation
CAAHEP-accredited programs are the gatekeeper for CSFA eligibility. These programs combine classroom instruction in surgical anatomy, physiology, and procedural technique with supervised clinical rotations in live operating rooms. Because NBSTSA will not accept a substitute pathway, choosing an accredited program is not optional - it is the single most consequential decision in your training timeline.
For a deeper dive into what the credential itself represents once you've completed training, see What Is CSFA Certification? and What Is A CSFA?, which explain scope of practice and how the role differs from surgical technologist positions.
CAAHEP Training vs. Exam Preparation
A common misconception is that finishing a CAAHEP program automatically prepares you for the CSFA exam format. It doesn't - at least not entirely. Clinical programs teach you to perform the work; the exam tests whether you can recall and apply that knowledge under a strict 4-hour, computer-based, multiple-choice format administered at PSI testing centers. These are different skills, and treating them as identical is one of the most frequent reasons qualified assistants underperform on test day.
The exam itself consists of 175 total questions, of which 150 are scored and 25 are unscored pretest items you cannot identify during the test. You need 99 correct scored answers to pass. That means your clinical training gives you the raw knowledge, but dedicated exam preparation - reviewing content by domain weight, practicing the multiple-choice question style, and simulating timed conditions - is what converts that knowledge into a passing score. Our companion resource, CSFA Study Guide 2026: How to Pass on Your First Attempt, walks through this transition in detail.
Key Takeaway
Treat your CAAHEP clinical rotations and your exam review as two separate training phases. Finishing school does not mean you're exam-ready; budget dedicated review time after graduation.
How Training Maps to the Three Exam Domains
NBSTSA organizes the CSFA exam into three content domains, and understanding their relative weight should directly influence how you allocate training and review hours. A full breakdown of question types and content depth for each domain is available in CSFA Exam Domains 2026: Complete Guide to All 3 Content Areas.
| Domain | Exam Weight | Training Focus |
|---|---|---|
| Perioperative Care | 55% | Intraoperative procedures, positioning, hemostasis, wound closure, tissue handling |
| Basic Science | 31% | Anatomy, physiology, microbiology, pharmacology as applied to surgical settings |
| Ancillary Duties | 14% | Equipment, documentation, administrative and support responsibilities |
Perioperative Care (55%)
This domain dominates the exam and is driven largely by intraoperative procedures - the core hands-on work of first assisting. Your clinical rotations should give you repeated, varied exposure to different procedure types, not just volume in one specialty.
- Retraction technique and exposure management across procedure types
- Hemostasis methods and bleeding control decision-making
- Suturing, stapling, and wound closure principles
- Pre- and postoperative patient positioning and skin prep
Basic Science (31%)
This is the second-largest domain and often the one candidates underestimate. It tests whether you understand the "why" behind procedures, not just the steps.
- Surgical anatomy relevant to common procedures
- Physiological responses to surgical trauma and anesthesia
- Microbiology and infection control principles
- Pharmacology used in the perioperative environment
Ancillary Duties (14%)
Though smallest in weight, this domain covers the operational and documentation responsibilities that keep a surgical case running smoothly.
- Instrument and equipment handling protocols
- Documentation and chart accuracy requirements
- Communication with the surgical team and support staff
For domain-specific deep dives with practice-style content, see CSFA Domain 1: Perioperative Care (55%) - Complete Study Guide 2026, CSFA Domain 2: Ancillary Duties (14%) - Complete Study Guide 2026, and CSFA Domain 3: Basic Science (31%) - Complete Study Guide 2026.
Registration, Fees, and Testing Day Mechanics
Once your CAAHEP program is complete, registration and fee logistics become part of your training timeline. Exam fees are $240 for AST members and $350 for all others, and the exam is administered through PSI testing centers on computer. A detailed cost breakdown, including renewal fees, is available in CSFA Certification Cost 2026: Complete Pricing Breakdown.
Certification isn't a one-time event either - renewal requires AST-approved continuing education credits submitted to AST along with a renewal application to NBSTSA, or recertification by examination. Renewal by CE costs $45, while recertification by exam runs $450 for AST members or $550 for non-members. Understanding this cycle during initial training helps you plan CE tracking habits early rather than scrambling later.
Building a Domain-Weighted Study Schedule
Generic study techniques like spaced repetition or timed practice blocks only help if they're applied against the right content in the right proportions. Because Perioperative Care carries 55% of the exam weight, it deserves the largest share of your review calendar - roughly double the time you spend on Ancillary Duties.
Perioperative Care Foundations
- Review intraoperative procedure sequences across specialties
- Drill hemostasis, retraction, and closure decision points
Basic Science Integration
- Connect anatomy and physiology concepts to procedures reviewed in weeks 1-2
- Review microbiology and pharmacology relevant to perioperative settings
Ancillary Duties and Documentation
- Review equipment protocols and charting requirements
- Practice team communication scenarios
Timed Practice and Weak-Area Review
- Take full-length timed practice sets under 4-hour conditions
- Revisit lowest-scoring domain areas

Who Hires CSFA-Trained Assistants
Hospitals, ambulatory surgery centers, and surgical group practices hire CSFA-credentialed assistants specifically because the certification signals CAAHEP-level training plus a passed, standardized national exam. Employers in orthopedics, cardiovascular surgery, and general surgery frequently list CSFA as preferred or required.

Training Gaps That Sink First-Attempt Candidates
The 2025 national first-take pass rate for the CSFA exam was 62%, which means a substantial share of candidates need a second attempt. Most gaps trace back to training habits, not raw ability.
- Uneven clinical exposure: Rotations concentrated in one surgical specialty leave gaps in the broad intraoperative knowledge tested under Perioperative Care.
- Underestimating Basic Science: At 31% of the exam, this domain is too large to review superficially, yet many candidates treat it as secondary to hands-on skills.
- No timed practice: The 4-hour, 175-question format rewards pacing discipline; candidates who never rehearse under time constraints often run short.
- Ignoring Ancillary Duties: At 14%, it's tempting to skip, but missed points here add up against the 99-correct passing threshold.

Key Takeaway
Don't let strong clinical performance in one specialty create a false sense of exam readiness - the CSFA exam samples broadly across all three domains, so training must too.
