How to Become a Sterile Processing Technician
No college degree. Training programs finish in as few as four months. Certified techs are hired at hospitals and surgical centers nationwide, and the national average for a certified SPT sits near $57,000 as of 2026.
What a Sterile Processing Technician Does
SPTs decontaminate, inspect, assemble, package, and sterilize the surgical instruments used across a hospital or surgical center. Every reusable instrument that enters an operating room passes through sterile processing first.
The work happens in a Sterile Processing Department (SPD), sometimes called a Central Sterile Services Department (CSSD). Most hospital SPDs run around the clock across multiple shifts to keep surgical schedules moving. For the full breakdown, see the sterile processing technician job description.
Day-to-Day Responsibilities
- Receiving and sorting contaminated instruments from ORs and procedure areas
- Decontaminating with enzymatic soaks, ultrasonic washers, and automated cart washers
- Inspecting instruments for damage, wear, and functionality
- Assembling surgical trays and instrument sets to count sheets
- Packaging and sterilizing using autoclaves and other sterilization equipment
- Documenting sterilization cycles, biological test results, and instrument tracking
- Distributing sterile supplies to ORs, procedure areas, and patient care floors
SPTs do not work directly with patients, but their accuracy directly impacts patient safety. Improperly processed instruments contribute to healthcare-associated infections, which the CDC estimates affect roughly 1 in 31 hospital patients on any given day.
Education Requirements
A high school diploma or GED is all you need to enter a training program. No prior healthcare experience is necessary. In practice, most employers will not hire an uncertified tech without formal training or prior SPD experience, so completing a program and passing the CRCST exam is the standard entry point.
The Two Paths to CRCST
The CRCST, issued by HSPA, is the most widely recognized credential in the field and is named directly in state mandates and hospital job postings. There is a common misconception that you must complete 400 hours before you can sit for the exam. That is not accurate. HSPA offers two pathways. Full detail in the CRCST certification guide.
Inside the CRCST Exam
Three hours, 150 questions, computer-based at Prometric centers nationwide. There are no fixed national test dates; exams run year-round, which makes scheduling workable for people with jobs and families.
The fee is $140, of which $25 is a non-refundable application fee. Applications process in three to four weeks. Fail, and there is a mandatory six-week wait before you can retest. The cumulative pass rate is roughly 64.5%, meaning more than one in three candidates do not pass on the first attempt. Candidates who complete a structured training program outperform those relying on work experience or self-study alone.
Seven Knowledge Areas
- Central service work environment and workflow
- Cleaning, decontamination, and disinfection
- Preparation and packaging of instruments
- Sterilization methods and monitoring
- Storage and inventory management
- Distribution and handling of sterile supplies
- Professionalism and communication
Training Program Options
HSPA does not require a formal program to apply for the exam, but structured training prepares you for both the test content and real SPD work. Compare options in the training program guide.
Costs range from under $1,000 at some community colleges to $4,000–$5,000 with private online providers. Some include the textbook and exam voucher; others do not. Confirm exactly what is bundled before you pay.
States That Mandate Certification
- New York. Certification required before working as an SPT in any healthcare facility. New hires get 18 months to certify. A minimum of one year of experience in the prior four years is required for initial employment.
- New Jersey. CRCST or CSPDT required within three years of employment. Techs using ethylene oxide need a separate license from the NJ Department of Environmental Protection.
- Connecticut. Required under House Bill 5913 (effective January 1, 2016) for all new-entrant techs. Ten hours of continuing education annually.
- Delaware. Certification required within 18 months of hire at a hospital or freestanding surgical center.
- Tennessee. Required within 18 months of hire under the Central Service Technician and Surgical Technologist Regulation Act of 2020.
- Pending legislation. Massachusetts, Florida, and Minnesota have all been active in pushing toward mandates. Even in states without one, the overwhelming majority of hospital employers require or strongly prefer certification.
CSPDT and the Advanced Track
The CSPDT, issued by CBSPD, is the second major credential. It is NCCA-accredited, accepted by most employers, and recognized in state mandates alongside the CRCST. If you are deciding between them, read CRCST vs CBSPD or the full CBSPD certification guide.
Key differences: CSPDT renews on a five-year cycle versus annual for CRCST, and CBSPD exams run in scheduled windows rather than year-round. Eligibility requires 12 months of full-time SPD employment, completion of an accredited course, or other qualifying healthcare experience. Exam cost is $128. In hospitals, CRCST has broader adoption and appears by name more often in postings. For ambulatory surgical centers or physician offices, CBSPD's CASSPT is more targeted.
After the CRCST
Your First Year and the Path Up
Most entry-level positions start in decontamination, where instruments arrive from the OR for initial cleaning. Expect physically demanding work: long shifts on your feet, full PPE in the decon zone, and high instrument volume during peak surgical hours.
Starting pay for uncertified or newly certified techs typically runs $18–$23/hr depending on market and facility. Most hospital systems pay shift differentials for evenings, nights, and weekends, which adds meaningfully to take-home pay. Compare markets with the salary estimator or see 2026 salary data.
Year one is when you finish your 400 hours on the provisional pathway, learn your facility's instrument inventory and tray configurations, and build the practical knowledge that makes an experienced tech valuable. Turnover is high industry-wide, which means committed techs move into lead and senior roles faster than in many other healthcare support fields.
Advancement Track
Entry-level SPT → Lead / Senior Tech → SPD Supervisor → SPD Manager → SPD Director. Each step typically requires additional certification (CIS, CHL), broader facility knowledge, and management experience at the supervisory level. SPD Directors at large health systems earn $90,000–$120,000+. Some experienced techs move laterally into surgical technology, infection control, or healthcare supply chain.

Frequently Asked Questions
No. A high school diploma or GED is all that is required to enter a sterile processing training program. No prior healthcare experience is necessary, though it can be helpful.
No. HSPA offers two pathways. You can complete 400 hours first and then test, or take the exam first and earn Provisional CRCST certification, which gives you six months to complete and document your hours. The 400 hours are mandatory either way.
Online programs typically take four to twelve months. In-person and community college programs run three to twelve months and often include supervised hands-on components that may cover some or all of your required 400 hours.
The exam fee is $140, of which $25 is a non-refundable application fee. Applications are processed within three to four weeks. If you fail, there is a mandatory six-week waiting period before you can retest.
