If you're pursuing surgical tech certification, two credentials dominate the field: the CST (Certified Surgical Technologist) and the TS-C (Tech in Surgery, Certified). They test similar competencies, but they are not interchangeable in the eyes of employers, state licensing boards, or hiring managers reviewing a stack of applications.
This page covers the differences that actually matter for your career: who can sit for each exam, what it costs, which states accept each credential, and which one gives you the stronger position in a job search.
The CST is the dominant credential in surgical technology. It is issued by the NBSTSA (National Board of Surgical Technology and Surgical Assisting), required or preferred by the majority of hospitals, and recognized in every state that regulates the profession. The TS-C, issued by the NCCT (National Center for Competency Testing), is a legitimate alternative with a more flexible eligibility path, but it carries less weight with employers and faces restrictions in some regulated states.
If you graduated from an accredited program and can sit for either exam, the CST is the better career investment in most markets.
| CST | TS-C | |
|---|---|---|
| Issuing body | NBSTSA | NCCT |
| Credential letters | CST | TS-C |
| Exam questions | 175 (150 scored) | 150 |
| First-time exam fee | ~$195 to $225 | ~$155 to $185 |
| Renewal cycle | Every 4 years | Annual |
| CE credits to renew | 60 credits per 4-year cycle | 14 credits per year |
| Work experience pathway | No | Yes |
| Employer preference | Strong, widely required | Accepted at many facilities |
| State regulation compatibility | Accepted in all regulated states | Restricted in some states |
This is where the two credentials diverge most significantly.
To sit for the CST exam, you must meet one of the following:
There is no work-experience-only pathway. If you did not complete a formal accredited program, you cannot sit for the CST regardless of how many years you have worked in the OR.
The NCCT offers three pathways to sit for the TS-C:
The work experience pathway is the TS-C's primary differentiator. It serves surgical techs who entered the profession through on-the-job training before formal program requirements were standardized, or those who trained at facilities not connected to an accredited program.
Bottom line on eligibility: If you have a choice between the two, eligibility requirements should not be the deciding factor. If you cannot qualify for the CST due to your training background, the TS-C gives you a legitimate pathway to certification.
Neither credential is expensive relative to the earning potential, but there are real differences in long-term cost that most comparison articles skip over.

TS-C total first-year cost:
Where the math shifts: renewal costs
The CST renews every four years. You need 60 CE credits over that cycle. Many of those credits can be earned for free or low cost through employer-sponsored training, professional association memberships, and free online modules from AST.
The TS-C renews annually and requires 14 CE credits per year, which equals 56 credits over four years. The difference in CE volume is modest, but annual renewal means annual administrative overhead and annual renewal fees. Over a 20-year career, those renewal fee differences accumulate.
Net cost advantage: The TS-C is cheaper to obtain initially. The CST is comparable or slightly cheaper to maintain over a long career depending on CE sourcing.
This is the most important factor for job seekers and the one most comparison pages treat too diplomatically.
The CST is the preferred credential among hospital employers, surgical centers, and health system recruiters. It appears by name in the majority of surgical tech job postings that require certification. Many facilities list it as required, not preferred. Travel surgery companies and staffing agencies also default to CST when screening candidates.
The TS-C is accepted at a significant portion of facilities, particularly in states without credential-specific regulations, smaller surgical centers, and ambulatory surgery centers that prioritize verifiable competency over specific credentialing bodies. It is not a disqualifying credential, but it will not carry the same weight as a CST when a recruiter is comparing candidates.
Hiring manager reality: If two candidates are otherwise comparable and one holds a CST and one holds a TS-C, the CST candidate has the stronger application at most hospital systems. That gap narrows in markets with surgical tech shortages, but it does not disappear.
If you are entering the field and have the option, earn the CST first.
Several states regulate surgical technologists and specify which credentials satisfy licensure or registration requirements. State requirements change, so verify current rules with the relevant state board before relying on this summary.
States with surgical tech regulations (as of this writing):
The risk with the TS-C is that some regulated states specify NBSTSA certification explicitly, which would require you to obtain a CST before practicing legally in those states. If you hold a TS-C and are considering a move or a travel assignment, check the destination state's requirements before accepting a position.
Interstate mobility: Because the CST is accepted universally in regulated states, it creates fewer barriers if you relocate, pick up travel contracts, or work across state lines.

Choose the TS-C if:
Can you hold both? Yes. Some surgical techs earn the TS-C first through the work experience pathway and later add the CST after completing an accredited program or meeting eligibility through another route. Holding both has minimal practical benefit for most techs, but it does eliminate any employer objections entirely.
CST recertification:
Renewal happens every four years. You need 60 CE credits from approved sources or can opt to retake the exam. The NBSTSA provides a list of approved CE providers. The Association of Surgical Technologists (AST) offers member CE at reduced or no cost, and many hospital systems provide in-house CE that qualifies.
TS-C recertification:
Renewal happens every year. You need 14 CE credits annually from NCCT-approved sources. Annual renewal keeps your credential top of mind but also means an annual administrative task and fee. The NCCT's CE provider list is separate from the NBSTSA's, so confirm source eligibility before completing credits.
Is one exam harder than the other?
Both exams test core surgical technology competencies at a comparable level. Pass rates for both are generally in the 70 to 80 percent range for first-time candidates from accredited programs. Neither exam has a reputation for being significantly harder than the other.
Does the CST pay more?
Certification itself does not come with a fixed pay premium, but CST holders have access to a broader pool of positions including those at higher-paying hospital systems that require it. The credential expands your options; what you do with those options determines your income.
Will a TS-C get me a travel contract?
Many travel surgery staffing companies accept the TS-C. Some require the CST specifically. Review the credentialing requirements with each agency before committing to a contract, particularly for assignments in regulated states.
Can I list both credentials after my name?
Yes. The format would be, for example, Sarah Johnson, CST, TS-C. In practice, if you hold a CST, the TS-C adds little additional signal to most employers.
I have 10 years of experience but no certification. Which should I get?
If you meet the TS-C work experience pathway, it may be your fastest route to certification. Review whether your hours and documentation meet NCCT requirements. If you can also enroll in an accredited program to become CST-eligible, that is worth considering for long-term career mobility.
Browse open positions that specify CST or TS-C requirements, filter by state, and apply directly to employers.
