1.1 About the NCCT TS-C Exam

1.1 About the NCCT TS-C Exam

The National Center for Competency Testing (NCCT) offers the Tech in Surgery - Certified (TS-C) credential to validate the essential knowledge, clinical judgment, and perioperative skills required of surgical technologists. Accredited by the National Commission for Certifying Agencies (NCCA), the TS-C credential serves as a nationally recognized benchmark of professional competency, confirming that a surgical technologist is thoroughly equipped to safeguard patient safety, maintain aseptic integrity, anticipate surgical steps, and manage complex intraoperative technologies in healthcare facilities across the United States.

Earning the TS-C designation requires passing a rigorous, computer-based examination developed through a comprehensive nationwide Job Task Analysis (JTA). This section breaks down the administrative logistics, candidate eligibility pathways, clinical case documentation requirements, official blueprint weighting, and pacing strategies necessary to master the exam.

Scored vs. Unscored Pretest Items

Of the 175 items presented on the examination, exactly 150 are scored operational items that determine your final performance. The remaining 25 items are unscored pretest (pilot) items placed on the exam by NCCT psychometricians to gather statistical difficulty and discrimination data for future exam forms.

[!IMPORTANT] Pretest Item Invisibility: Unscored pretest items are completely indistinguishable from scored operational items. They appear seamlessly throughout all content domains. Candidates must approach every single item with identical clinical rigor and focus, never attempting to guess whether a difficult or unfamiliar item is scored.

Scoring Mechanics: Scaled Scoring Standard

NCCT utilizes criterion-referenced scoring with scaled score reporting. Raw scores (the number of correctly answered operational items) are converted onto a standardized 0-100 scale, and a scaled score of 70 is the uniform passing threshold across all NCCT certification examinations. This is not a percentage and does not mean 70%. Psychometric equating adjusts for minor statistical variations in difficulty between forms: a harder form requires slightly fewer raw correct answers to reach a scaled 70, and an easier form requires slightly more, so every candidate is held to an identical competency standard.

2. Candidate Eligibility Pathways

NCCT maintains several eligibility routes to ensure that all certified surgical technologists possess verifiable clinical education, hands-on surgical experience, or documented practical training.

---

3. Critical Skill Competency Documentation: The 125-Case Standard

Education-route candidates must complete NCCT's critical skill competency documentation verifying hands-on surgical case experience:

• Total case volume: minimum 125 surgical cases.
• First scrub: at least 90 of the 125 cases must be performed as the first scrub (the primary scrubbed technologist who sets up the field, performs counts with the circulator, and passes instruments).
• Case mix: 30 to 50 cases in general surgery, plus 75 to 95 cases distributed across at least three (3) different surgical specialties, chosen from NCCT's specialty table: gynecology, genitourinary, cardiovascular, neurosurgery, obstetrics, thoracic, peripheral vascular, ophthalmology, otorhinolaryngology, orthopedic, and plastic/reconstructive surgery. Diagnostic scopes are capped at a maximum of 15 cases.
• Case documentation must be verified by supervisors who had direct oversight of the applicant's performance. Education-route candidates may test before every case is logged, but certification is not granted until all cases are documented and verified.

First-Scrub vs. Second-Scrub Participation

• First scrub: The technologist performs the surgical hand scrub, gowns and gloves, sets up the back table and Mayo stand, performs surgical counts with the circulating nurse, drapes the patient, passes instruments, anticipates the surgeon's needs, and participates in dressing application and room breakdown.
• Second scrub: The technologist is scrubbed in but assists the primary scrub — holding retraction, cutting sutures, suctioning, and observing specialized sequences. Second-scrub cases document exposure but cannot substitute for the first-scrub minimum.

4. Exam Blueprint: The Official Detailed Test Plan

NCCT's Detailed Test Plan (effective January 2024) reflects the national job analysis and allocates the 150 scored items across four content categories. Because NCCT publishes item counts rather than percentages, the percentages below are derived (item count / 150). All sections of this study guide map to these official task areas.

+-----------------------------------------------------------------------------+
|                 TS-C DETAILED TEST PLAN (EFFECTIVE JANUARY 2024)            |
|                                                                             |
|   [2] Preoperative Care and Preparation ......... 48 items (32%)            |
|   [1] Perioperative Care and Preparation ........ 41 items (~27%)           |
|   [3] Intraoperative Care and Preparation ....... 37 items (~25%)           |
|   [4] End of Procedure Tasks and Postoperative .. 24 items (16%)            |
|                                                                             |
|   *Total Scored Items: 150 (Plus 25 Unscored Pretest Items = 175 Total)     |
+-----------------------------------------------------------------------------+

[!NOTE] Study Priority: Preoperative Care and Preparation is the single largest category (48 items, 32%), and Surgeon Support (26 items) is the largest individual task area anywhere on the exam. Sterile technique, case setup, instrument handling, and counts drive the majority of scored content — prioritize them ahead of niche specialty trivia.

NCCT also publishes an Essential Knowledge Base of 23 integrated concepts tested throughout all categories — aseptic technique, anatomy and physiology, microbiology, pharmacology, emergency preparedness, healthcare regulations, pathophysiology, patient rights, surgical counts, surgical conscience, instrumentation, patient positioning, draping, tissue specimen handling, surgical procedures, dressings, wound closure supplies, and post-surgical devices, among others.

5. Pacing Benchmark and Strategic Test-Taking Framework

Managing your time effectively during the 240-minute testing window is essential to avoid fatigue and ensure every item receives thorough consideration.

Pacing Benchmarks

With 175 items across 240 minutes, you have an average of 1.37 minutes (82 seconds) per item.

|   ELAPSED TIME          TARGET ITEM COMPLETED        REMAINING TIME         |
|   --------------------  ----------------------------  --------------------  |
|   60 Minutes (1 Hour)   Item 45                       180 Minutes           |
|   120 Minutes (2 Hours) Item 90 (Halfway Mark)        120 Minutes           |
|   180 Minutes (3 Hours) Item 135                      60 Minutes            |
|   220 Minutes           Item 175 (Finished Pass 1)    20 Minutes            |
|   240 Minutes (4 Hours) Final Review of Flagged Items  0 Minutes            |
+-----------------------------------------------------------------------------+

The Three-Pass Strategy

1. Pass 1 (Immediate Recall & Core Scenarios): Answer all items where the answer is immediately clear (e.g., instrument identification, sterilization parameters, microbiology definitions). If an item requires extensive analysis or calculation, select your best preliminary choice, flag it, and move forward.
2. Pass 2 (Scenario Analysis & Drug Calculations): Return to flagged scenario-based items and pharmacological dosage calculations. Carefully dissect the surgical context, patient position, and procedural stage.
3. Pass 3 (Final Sweep): Ensure that no item is left unanswered. NCCT exams do not penalize incorrect guesses; a blank item is always scored as incorrect.

Stem Analysis and Qualifier Keywords

NCCT exam items frequently contain specific clinical qualifiers that dictate the single correct response:

• "FIRST" / "INITIAL": Tests chronological sequence and patient safety priorities (e.g., "What is the FIRST action when an instrument count is incorrect?").
• "MOST APPROPRIATE" / "BEST": Evaluates clinical judgment among several plausible options based on established AORN/AST guidelines.
• "IMMEDIATE": Demands urgent safety intervention (e.g., managing malignant hyperthermia or immediate sterile field contamination).
• "EXCEPT" / "CONTRAINDICATED": Requires identifying the incorrect or unsafe practice among three correct standards.

6. Certification Maintenance and Continuing Education (CE)

Maintaining the TS-C credential requires ongoing professional engagement and compliance with NCCT's recertification policies.

• Annual Renewal: Credential holders must renew their certification annually by remitting the renewal fee and completing NCCT's required annual Continuing Education (CE) hours (14 contact hours per year through the NCCT CE library or approved outside CE).
• Qualifying CE Activities: Credits may be earned through NCCT-approved educational modules, accredited perioperative courses, healthcare conferences, college coursework in biological sciences, and hospital in-service training. Outside CE submissions may require an audit taking 9-13 business days.
• Inactive Status and Invalidation: Certification moves to inactive if recertification is not processed before expiration; NCCT charges no late fee for recertifying, but a credential goes invalid after five consecutive years without recertification and can no longer be used or reinstated without re-examination.
• Employer Requirements: Many employers separately require current Healthcare Provider BLS/CPR certification through an accredited provider (American Heart Association or American Red Cross) as a condition of employment.
