About the CST
The CST is the primary credential for surgical technologists and is now required or strongly preferred by most US employers at hire. The 2020 NBSTSA policy update made graduation from a CAAHEP or ABHES accredited program a prerequisite. The exam validates your ability to anticipate surgeon needs, maintain the sterile field, and assist safely across the full range of surgical procedures.

TS-C - Tech in Surgery - Certified
Advanced NBSTSA credential for first assistants
The TS-C is an advanced credential for experienced CSTs who function as surgical first assistants. First assistants perform hands-on tasks beyond the traditional scrub role: retracting tissue, providing hemostasis, suturing, and assisting with exposure. This expanded scope commands meaningfully higher pay and is in growing demand at busy trauma and cardiovascular centers.
Eligibility
- +Valid CST credential required
- +Minimum 2 years of ST experience
- +Documented first-assistant cases or formal training
- +Employer letter confirming first-assistant duties
TS-C holders typically earn $68,000-$85,000 in hospital settings. Some Level I trauma centers and academic centers pay $90,000+ for experienced TS-C holders. The credential also supports billing for first-assistant services in some state and payer contexts.
TS-C vs CSFA: The TS-C is lower cost (exam fees only, no required program). The CSFA requires a $8-18k program but delivers $20-30k in annual premium. For dedicated first-assistant career paths, the CSFA offers stronger ROI. See full CSFA guide.
