If you’ve ever had surgery or another medical procedure (or have known someone who has), you probably didn’t give much thought to the medical tools involved. But those tools — and how clean they are — are the difference between a successful procedure and one that could lead to an adverse event like an infection, illness, or even death.
To ensure patient safety, sterile processing technicians decontaminate, inspect, sterilize, and manage the reusable instruments and equipment used in medical procedures. This may include scalpels, scissors, endoscopes, basins, clamps, or others.
Their work is primarily behind the scenes, but that doesn’t make their contribution to patient safety any less vital. If you love the idea of a career where you can have a positive impact on patient safety and outcomes, but would rather skip the clinical, patient care side of the house, a career as a sterile processing technician may be perfect for you!
What do sterile processing technicians do?
At a high level, the core tasks for a sterile processing technician include:
- Decontamination: This is where used instruments are cleaned for the first time after a procedure.
- Inspection and assembly: At this stage, the technician checks each item for damage, wear and tear, or some other reason it may need to be taken out of rotation, then assembles instrument sets for upcoming procedures.
- Sterilization: This is the stage most people picture. The technician sterilizes the equipment and keeps thorough documentation of each load, including what was in it and the sterilizer test results.
- Storage and distribution: This closes the loop. Sterile items are stored until they’re needed, and the technician checks that supplies haven’t expired and maintains detailed inventory records of equipment usage.
Contrary to what you might think, this job is about more than simply cleaning medical instruments and equipment. There’s also a fair amount of record keeping involved, and for good reason: surgical instruments need to be pristine and completely sterilized, with documentation to prove it. The health of each person undergoing surgery depends on it.
Where sterile processing technicians work and what a typical day looks like
Sterile processing technicians can work in hospitals or other medical facilities where surgery takes place and equipment requires sterilization. The U.S. Bureau of Labor Statistics (BLS) doesn’t track sterile processing technicians separately. Instead, it counts them as part of a broader occupation, medical equipment preparers, which also includes workers who prepare, install, or clean laboratory and other healthcare equipment.
According to BLS, major employers of medical equipment preparers include:
- General medical and surgical hospitals
- Dentist offices
- Physician offices
- Outpatient care centers
- Employment services, such as staffing agencies
No matter what kind of environment a sterile processing technician works in, however, some aspects of the job are inherent. Here are some of the challenges of the role, according to O*NET’s work context data for medical equipment preparers:
- Standing is continual or near-continual for 31% of these workers and more than half the time for another 29%.
- Exposure to contaminants is a daily condition for 35%.
- 78% report working under time pressure every day.
That means a typical day will involve lots of time on your feet and a strict adherence to protocol to ensure you keep both yourself and the equipment you work with safe and away from contaminants. You’ll likely interact with plenty of hospital staff, such as nurses or members of the surgery team. Some softer skills that may help in this role:
- Attention to detail
- The ability to communicate effectively
- Comfort in a healthcare setting
- Adaptability, especially as emergencies occur or priorities shift based on circumstances
Education and certification requirements
To enter this field, you’ll need at least a high school diploma or GED. A training certificate program shortens that ramp and prepares you for the field's main credential, Certified Registered Central Service Technician (CRCST) through the Healthcare Sterile Processing Association (HSPA).
The CRCST exam consists of 150 multiple-choice questions that must be completed within three hours. The application fee is $140. Full certification also requires 400 hours of hands-on experience, split across the same stages you'd work in a real department: 120 hours in decontamination, 120 in preparation and packaging, 120 in sterilization and disinfection, 24 in storage and distribution, and 16 in quality assurance.
Those hours must be completed in a sterile processing department, either in a paid job or as a volunteer. If you train online, you’ll need to arrange this on your own.
You don’t have to finish those hours before you test. Under HSPA’s provisional option, you can pass the exam first and then submit your 400 hours within six months. If you miss that deadline without an approved extension, you’ll lose your provisional certification and have to retake the exam.
Seven states require certification to work in sterile processing:
- Connecticut
- Delaware
- Minnesota
- New Jersey
- New York
- Pennsylvania
- Tennessee
HSPA tracks state legislation and notes that its own list may not reflect the most current rules, so confirm your state’s requirements before you plan around them.

Sterile processing technician salary
According to BLS data, medical equipment preparers earned a median wage of $22.93 an hour in May 2025, or $47,700 a year. That means half of workers earned more and half earned less.
Pay also varies by location. Our guide to sterile processing technician salary by state breaks down median pay in every state and the District of Columbia.
Sterile processing technician job outlook
BLS projects employment of medical equipment preparers to grow 11% from 2025 to 2035 — much faster than the average for all occupations. Over that period, O*NET estimates about 10,700 job openings each year, on average. That count includes openings created when workers retire or move into other occupations, not just new positions.
Is sterile processing a good fit for you?
If you’re a fan of strict, regimented processes, and you perform well in settings where those are a core part of your job, this career is probably a good fit for you. If you're the type of person who reads the whole instruction sheet, notices when one item is missing from a set, and would rather follow a validated procedure than improvise, the department will feel like home. Being in moderately good physical condition helps as well.
The work follows the same steps every day, even when the pace shifts with the surgery schedule. If you’re weighing this against working inside the operating room, our comparison of sterile processing technician vs. surgical technician breaks down the two paths side by side.
Train to become a sterile processing technician with U.S. Career Institute
U.S. Career Institute’s online Sterile Processing Technician certificate program can be completed in as little as four months, with part-time students generally taking four to nine months to finish. You can move as fast as you want through its 23 lessons. The curriculum covers:
- Medical terminology
- Aseptic technique and infection control
- Decontamination and high-level disinfection
- Instrument preparation and packaging
- Sterile storage and inventory
- Documentation and record keeping
The program prepares you for the written portion of the CRCST exam, but keep in mind that you will still need to secure 400 hours of hands-on training in a sterile processing department to earn your full certification. You'll need to arrange those hours independently.
