CSFA and CST are different credentials from different certifying bodies: the CSFA (Certified Surgical First Assistant) is administered by NBSTSA, while the CST (Certified Surgical Technologist) is administered by NBSTSA. Which one fits depends on your role and career direction — the official eligibility rules and exam outlines (linked below) are the deciding documents. Here is a side-by-side view, plus free practice questions for both so you can feel the difference yourself.

The quickest way to judge which exam fits you is to answer real questions from each. These are genuine cards from both decks:
What specific elements must be documented in the medical record regarding the Time Out protocol to meet safety standards?
Show answer →Documentation must include the names/roles of participants, the verification of patient identity, correct site/side, procedure to be performed, and confirm that all relevant images/implants are available. Rationale: This creates a legal and clinical audit trail. NBSTSA emphasizes that documentation is not just a check but a verification that a verbal process occurred.
Upon physical assessment, the CSFA notes the patient has a Mallampati Class III airway. What specific anatomical structures are visible, and what does this imply for intubation?
Show answer →Only the soft palate and the base of the uvula are visible. This indicates a Difficult Airway, suggesting that endotracheal intubation may be challenging. Mallampati Class III and IV are high predictors of difficult laryngoscopy. CSFA Role: Ensure the presence of a difficult airway cart and fiberoptic equipment. Exam Tip: Class I = full visualization; Class II = partial uvula; Class III = base of uvula; Class IV = hard palate only.
An ST is asked by a surgeon to perform a task that is outside their state's defined scope of practice. The ST performs the task, and the patient is injured. Who is legally liable for this injury?
Show answer →Both the Surgeon and the Surgical Technologist. The ST is responsible for knowing their scope of practice (governed by state law and AST standards). Performing a task outside that scope, even under a surgeon's direction, constitutes professional negligence. Exam Strategy: NBSTSA emphasizes Primum Non Nocere (First, do no harm). The ST has a legal and ethical obligation to refuse any task they are not trained, certified, or legally permitted to perform.
A preference card for a vascular procedure lists '1% Lidocaine with Epinephrine' for the local anesthetic. Why would a surgeon specifically prefer the addition of Epinephrine for a skin incision?
Show answer →Epinephrine acts as a vasoconstrictor, which provides two benefits: it prolongs the duration of the anesthetic by slowing absorption and decreases bleeding at the incision site (hemostasis). Rationale: CSTs must recognize the 'why' behind card preferences. NBSTSA Tip: Note the contraindications for Epinephrine, such as use on 'fingers, toes, nose, or hose' (appendages with limited collateral circulation), though this is surgeon-dependent.
They are independent credentials from NBSTSA and NBSTSA respectively; many professionals hold more than one certification. Check each body's eligibility requirements on the official sites linked above.
They test different bodies of knowledge, so difficulty depends on your background. Try free practice questions for both on this page — the one that feels further from your daily work will need more prep time.
Always use the certifying bodies directly: NBSTSA for the CSFA and NBSTSA for the CST. Links to both official sites are on this page.
Eligibility rules, fees, question counts and passing standards are set by the certifying body and change over time. Always confirm them at the source before you apply or schedule your exam — our flashcards are practice material, not the official handbook.
