What it pays

How much does this credential pay?

$62,830 median for surgical technologists (BLS, May 2024) — SOC 29-2055

The direct answer is that surgical technologists, SOC 29-2055, earned a median of $62,830 per year in May 2024, the most recent BLS Occupational Employment and Wage Statistics survey, and it is the correct series to cite for a CST because the credential is the national standard certification for this occupation and BLS classifies by job duties. The distribution matters as much as the median: the lowest 10 percent of surgical technologists earned less than $43,290 and the highest 10 percent more than $90,700, a spread driven by employer type, shift work, geography and certification status rather than by seniority alone — hospitals, the setting for about three-quarters of the occupation, pay most of the midpoint, and outpatient surgery centres are a growing second market. Employment is healthy: BLS projects surgical technologist employment to grow 4 percent from 2024 to 2034, and when surgical assistants are counted with technologists the combined projection is 5 percent, with about 8,700 openings a year across the pair, driven by an aging population needing more surgical procedures and by the shift of more surgery into ambulatory settings. Where the CST sits in that picture is precise: NBSTSA certification is the credential most employers require or prefer, roughly 88,000 CSTs hold active certification, and the certification is effectively a gate for the best-paying scrub roles — some states regulate the occupation and tie practice to certification or graduation from an accredited program. The honest caveats are the same ones the pass-rate data imply: the exam is genuinely demanding — roughly three in ten first-time candidates fail — and the salary payoff depends on the setting and the region as much as the credential. The realistic career line is: earn the CST, work the hospital operating-room schedule including call and evenings, let the 4-year renewal cycle with 60 CEUs keep the credential current, and use the OR experience to move toward first-assist work or a management track if the clinical path is right.

Your schedule

How long should I study for it?

100-140 hours over 3-6 months of focused study

Plan three to six months and roughly 100 to 140 hours of review, starting from the premise that the CST rewards breadth under time pressure: 175 questions in 4 hours across the three broad domains of the 2024 NBSTSA content outline, and candidates who study only their favourite OR rotations routinely drop the equipment-sterilisation and administrative items. The scored 150 questions break down as Perioperative Care with 97 items (Preoperative Preparation 19, Intraoperative Procedures 68, Postoperative Procedures 10), Ancillary Duties with 23 items (Administrative and Personnel 7, Equipment Sterilization and Maintenance 16), and Basic Science with 30 items (Anatomy and Physiology 18, Microbiology 6, Surgical Pharmacology 6) — so intraoperative care is nearly half the paper, and that is where study time should concentrate first. Use the NBSTSA content outline and the CST Study Evaluation guide as the syllabus, and structure the months in three phases: six weeks on perioperative care, working sequentially through the pre-, intra- and post-operative items with emphasis on the surgical procedures, aseptic technique, instrument and supply handling, and patient-positioning questions that dominate; three weeks on the ancillary duties including the equipment-sterilisation sub-area that most study guides skip and the administrative items; and three weeks on basic science, concentrating on the anatomy, microbiology and pharmacology most relevant to the OR. The last four to six weeks are for practice: NBSTSA sells online practice exams that mirror the format, and running at least two timed 4-hour sessions is non-negotiable because the 175-question length is the real enemy — candidates run out of clock in the final quarter of the paper, not on the early questions. Plan to book the exam through PSI either at a centre or via Live Remote Proctoring, and confirm your eligibility documents — graduation from a CAAHEP- or ABHES-accredited programme or a qualifying military programme — are complete before applying, because the ATT letter and scheduling step follow application approval.

1. Weeks 1-68-10 hrs/week

   Perioperative care (97 of 150 scored items)

   • Study preoperative preparation: patient assessment, informed consent, and OR setup
   • Master intraoperative procedures — the 68-item heart of the exam: aseptic technique, instrument and supply handling, counts, and surgeon anticipation
   • Cover postoperative procedures: dressing and specimen handling, and room turnover
   • Practise the "anticipate the surgeon" questions, which candidates routinely miss by learning lists instead of workflows
2. Weeks 7-96-8 hrs/week

   Ancillary duties and equipment sterilisation

   • Study equipment sterilization and maintenance — the 16-item sub-area most study guides overlook and candidates fail
   • Learn decontamination, sterilization methods, and the difference between sterile processing roles and scrub roles
   • Cover administrative and personnel items: documentation, patient transport, and safety practices
   • Drill the instrument-identification questions against labelled photo sets
3. Weeks 10-126-8 hrs/week

   Basic science

   • Review anatomy and physiology at the level the OR demands — the structures involved in common procedures
   • Study microbiology: transmission, disinfection, and the organisms most relevant to surgical infection control
   • Cover surgical pharmacology: anaesthetics, antibiotics, and agents used in the OR
   • Take the first NBSTSA online practice exam and map your misses to the content outline
4. Weeks 13-168-10 hrs/week

   Timed practice and gap closure

   • Run two full-length timed practice exams under the 4-hour limit to build the stamina the 175-question paper demands
   • Re-drill every content-outline area you miss, starting with intraoperative care
   • Memorise the high-frequency facts: sterile-field rules, count procedures, and instrument names
   • Confirm eligibility, apply, receive the ATT, and schedule through PSI; rest the day before

What to buy

Which study resources are worth paying for?

The buying decision for the CST is small and concentrated: the NBSTSA content outline and study evaluation are free and define the scope, the official online practice exams are the highest-value purchase, and the exam fee dominates the budget. The current exam fee is $190 for AST members and $290 for non-members per the NBSTSA FAQ, though the 2025 CST Exam Application lists $230 for AST members and $340 for non-members — a discrepancy that reflects the fees changing between documents, so confirm the figure on the application you submit rather than trusting either number blindly. A non-refundable application processing fee applies, rush processing costs extra, and renewal costs either CE submission or a renewal-by-exam fee of $299 for AST members and $399 for non-members. The practical buying order is: download the free content outline and study evaluation first and build the plan from them; then buy the NBSTSA online practice exams, which are the only rehearsal scored against the real item style and the real 175-question length; then spend on textbooks and photo sets only for depth in the areas the outline shows you are weak in, which for most candidates means the equipment-sterilisation sub-area and intraoperative instruments. Third-party question banks are useful for additional drilling but weaker on the real exam's phrasing, and they should not be the readiness tool. Finally, the programme-based resources a candidate already owns — course notes, clinical references, and lab time — should be exhausted before any commercial course is considered, because the CST rewards the clinical depth a programme provides more than any prep product does. The total cost of the certification is the exam fee plus at least one realistic retake possibility, plus the 4-year renewal cost, and a candidate should budget all three at the start rather than discover the renewal fee after passing.

Prices checked 2026-08 in USD and approximate. The NBSTSA FAQ lists the first-time CST fee as $190 (AST) / $290 (non-member) while the 2025 Exam Application lists $230 / $340; confirm the current fee on the application you submit. Fees are non-refundable once processed. We do not rank by commission.

What you'll face

What question types will I see?

The CST is a computer-delivered, closed-book exam of 175 multiple-choice questions in 4 hours, of which 150 are scored and 25 are unscored pretest items mixed randomly through the paper, so every question must be treated as if it counts. The scored items follow the 2024 NBSTSA content outline: Perioperative Care carries 97 items across Preoperative Preparation, Intraoperative Procedures (the 68-item core), and Postoperative Procedures; Ancillary Duties carries 23 items across Administrative and Personnel duties and Equipment Sterilization and Maintenance; and Basic Science carries 30 items across Anatomy and Physiology, Microbiology, and Surgical Pharmacology. Question types are essentially single-answer multiple choice, but they come in three practical families: direct-knowledge items on facts, instruments, rules and terminology; applied clinical-scenario items that describe an operative situation and ask what the technologist should do, which dominate the intraoperative domain and reward knowing why aseptic rules exist; and safety-and-judgement items on counts, sterile-field breaches and specimen handling, where the scenario inverts the textbook rule — a candidate who memorised the rule but not the principle behind it will miss the inverted item. The pacing mathematics are unforgiving: roughly 105 questions per hour for 4 hours is achievable only if the scenario items are answered at a working tempo, and with no penalty for guessing and every question equal, the discipline is to answer everything and never sit on a hard item. The passing standard is set psychometrically and reviewed periodically, with recent sources citing roughly 98 of 150 scored questions, so the aim on practice should sit above that line. The score report delivered through PSI shows your outcome, and the domain structure gives a failing candidate a precise map of where the next attempt should concentrate — which is exactly why the report should be read before a retake is booked, not after it.
