If you want to become a Certified Surgical Technologist, or keep your credential active, this guide covers the essentials: what the CST credential is, who issues it, who can qualify, what the exam looks like, how much it costs, how renewal works, and why certification matters in the job market. The CST credential is issued by the National Board of Surgical Technology and Surgical Assisting, or NBSTSA. NBSTSA describes CST as the leading national credential for surgical technologists, and notes that it is preferred or required by many employers and required by many states.
CST stands for Certified Surgical Technologist. It is the best-known national certification for surgical techs in the United States and is designed to verify that the holder has met recognized standards in surgical technology knowledge and practice. NBSTSA states that earning the CST can support stronger job opportunities, travel opportunities, and earning potential.
For job seekers, that matters. Many hospitals and surgical employers prefer certified candidates because certification signals formal training, exam-based competency, and commitment to the profession. AST also advocates for hiring standards tied to graduation from an accredited program and obtaining the CST credential.
The CST credential is issued by the National Board of Surgical Technology and Surgical Assisting (NBSTSA). NBSTSA sets eligibility rules, administers the certification process, and oversees renewals and recertification policies. AST works alongside NBSTSA on continuing education policy, but the credential itself is issued and controlled by NBSTSA.
To sit for the CST exam, candidates must first establish eligibility through NBSTSA. The main pathways include:
The standard path is graduating from an NBSTSA-recognized surgical technology program. NBSTSA says applicants under this route must provide documentation such as an official notarized letter from the program director, graduation certificate, or official transcripts.
Candidates who are currently certified, or were previously certified, may also establish eligibility when renewing by examination.
NBSTSA also allows eligibility for graduates from programs that lost accreditation, failed to renew accreditation, or were undergoing accreditation, as long as the student was enrolled or graduated during the qualifying time window described by NBSTSA.
Candidates who successfully completed a military training program in surgical technology may qualify. NBSTSA lists required documentation including a DD214 showing graduation from a military training program and or a graduation certificate.
The current NBSTSA candidate handbook states that the CST exam includes 175 multiple-choice questions, with 150 scored questions and 25 unscored pretest questions distributed throughout the exam.
The exam content is based on current job-analysis data from practicing surgical technologists nationwide. The major content domains include perioperative care, ancillary duties, and basic science. In the current handbook breakdown, the exam outline includes 97 perioperative care items, 23 ancillary duties items, and 30 basic science items, totaling the 150 scored questions.
A useful point for candidates: the test is broad. It is not only about instrumentation. It also touches pre-op preparation, intra-op procedures, post-op responsibilities, sterilization and maintenance, anatomy and physiology, microbiology, and pharmacology.
If you have heard that the pass rate is around 70 percent, that is directionally correct, but it varies by year. NBSTSA’s published certification data shows a 68.6% national first-time pass rate in 2025, 71.8% in 2024, 69.1% in 2023, and 70.0% in 2022.
So, describing the CST exam as having an approximately 70 percent first-time pass rate is reasonable, but the most current published figure is 68.6%.
Your draft listed $190/$290, but the current NBSTSA candidate handbook shows updated fees. For the CST examination application, the listed fees are:
The handbook also states that the application processing fee is non-refundable once processed.
If you want this page to stay current and avoid publishing outdated numbers, use the current fee structure above rather than the older $190/$290 figures.
The CST exam is passable, but it is not something most candidates should take lightly. Because it spans sterile technique, procedures, instrumentation, anatomy, pharmacology, and OR workflow, success usually comes from organized review rather than last-minute cramming. NBSTSA’s own data, showing first-time pass rates hovering around 69 to 72 percent in recent years, suggests the exam is very manageable for prepared candidates, but not automatic.
A strong practical benchmark is this: if you graduated from a solid program, know your perioperative workflow, and study against the official content outline and references, you are in a good position.
NBSTSA points candidates to several official prep tools and study aids:
The handbook includes the content outline, sample questions, and the recommended reference list. This should be the first resource every candidate reviews.
NBSTSA publishes the exam content breakdown so candidates know what subject areas appear on the exam and how heavily each is weighted.
NBSTSA’s current handbook references texts such as Alexander’s Care of the Patient in Surgery, Surgical Technology: Principles and Practice, Surgical Technology for the Surgical Technologist: A Positive Care Approach, Pharmacology for the Surgical Technologist, and Surgical Instrumentation: An Interactive Approach.
NBSTSA says candidates can use official online practice examinations and a mobile study app with more than 300 questions.
AST also maintains CE and recertification resources that become especially important once you are certified and need to maintain currency.
CST certification is not a one-time credential you can ignore forever. To stay current, certificants must renew. AST states that CST professionals must earn 30 continuing education credits every two years, including 4 live credits, before the cycle expires.
NBSTSA’s renewal page states that after AST approves the CE credits, the certificant completes the renewal application and submits a $40 renewal fee.
If you miss the renewal window, NBSTSA notes there can be a $100 late fee within the allowed late period, and if you do not earn the required CE credits during your certification cycle, renewal may require taking the exam again.
Yes. NBSTSA allows CST professionals to renew by examination. The current renewal application lists renewal by examination at $440 for AST members and $540 for non-members.
That makes CE-based renewal the better path for most working surgical techs, since it is cheaper and avoids the pressure of retesting.
The CST credential includes a legitimate military route. NBSTSA explicitly states that candidates who successfully completed a military training program in surgical technology may qualify for the exam with the required documentation.
NBSTSA also notes in the candidate handbook that military applicants stationed overseas may request testing through a base education office rather than a standard testing center in certain circumstances.
That makes CST certification a strong civilian credential option for service members transitioning into healthcare careers after military training.
For employers, certification can reduce uncertainty. Hiring a CST means the candidate has completed an eligibility pathway accepted by NBSTSA and passed a standardized national examination. NBSTSA also states that the credential is preferred or required by most employers nationwide and required by many states.
For candidates, that can translate into several advantages:
For most aspiring surgical techs, yes. If you want the broadest range of opportunities, especially in hospitals or travel roles, CST certification is one of the most important credentials you can add. It is nationally recognized, tied to employer preference, and backed by a formal renewal structure that helps keep your qualifications current.
CST certification remains one of the key credentials in surgical technology. It is issued by NBSTSA, usually requires graduation from a recognized program or qualifying military training, and involves a 175-question exam with 150 scored questions. Current published first-time pass rates sit around 70 percent, the current exam fee is $230 for AST members and $340 for non-members, and renewal requires 30 CE credits every two years plus NBSTSA renewal processing.
