What is a Sterile Processing Technician?

When you think of hospitals, you probably imagine doctors, nurses, and patients. But there are important healthcare workers you might not see — like Sterile Processing Technicians (SPTs). Even though they don’t work directly with patients, their job is critical for keeping surgeries and medical procedures safe and successful.
What Does a Sterile Processing Technician Do?
A Sterile Processing Technician (also called a Central Service Technician, Medical Device Technician or Instrument Technician) makes sure surgical instruments and medical equipment are clean, sterilized, and ready for use. They do everything from cleaning used surgical tools to organizing them so doctors and nurses can grab what they need right away.

Main Responsibilities of a Sterile Processing Technician
SPTs have a lot of important tasks to do every day. Here’s what their job usually involves:
- Decontamination: After surgeries, SPTs clean and disinfect tools to remove blood, tissue, and other gunk. They use special cleaning solutions, ultrasonic washers, and large instrument washers to get the job done.
- Inspection and Assembly: Once the surgical tools are clean, SPTs carefully check them for damage or wear. They have to be super careful to make sure everything works perfectly. Then, they put the instruments together into sets or trays that will be used in future surgeries.
- Sterilization: The surgical tools are then sterilized using either machines called autoclaves that use steam and pressure to kill any remaining germs. Sometimes, other methods like gas or chemicals are used, depending on the instrument.
- Storage and Distribution: After sterilization, the surgical tools are packaged and stored in a way that keeps them sterile. SPTs organize everything and make sure the right tools get to the right places when needed.

Why Sterile Processing Technicians Are So Important
Keeping surgical tools clean and ready to go isn’t just about being neat and clean — it’s about keeping patients safe from infections. Infections and transmissions of disease from dirty instruments can cause more surgeries, longer hospital stays, or even serious health problems. By making sure everything is sterile and ready to use, SPTs help save lives every single day.
Skills and Training Needed to Become an SPT
To become a Sterile Processing Technician, you usually need a high school diploma or GED. After that, you’ll need specialized training from community colleges or vocational schools. These programs teach you the skills you need and give you hands-on experience. I personally recommend using Preppy which is an Online Sterile Processing Technician Training Program that is flexible, affordable, and accredited.
Important Skills for SPTs:
- Attention to Detail: Making sure every surgical tool is clean and functions properly.
- Manual Dexterity: Handling tiny, delicate instruments with steady hands.
- Knowledge of Sterilization: Understanding the different ways to make instruments safe.
- Communication Skills: Working well with surgical teams and other healthcare staff.
- Physical Stamina: Being able to stand for long periods and lift heavy trays of surgical tools.
Most employers prefer SPTs who are certified. The most recognized certification is the CRCST (Certified Registered Central Service Technician) offered by HSPA (Healthcare Sterile Processing Association). This certification shows employers you have the right knowledge and skills to do the job well.

Job Outlook for Sterile Processing Technicians
The demand for Sterile Processing Technicians is growing. The U.S. Bureau of Labor Statistics says jobs for medical equipment preparers (which includes SPTs) are expected to grow by 6% from 2021 to 2031. That’s about as fast as most other fast growing jobs.
Why? Because more people are having surgeries, and there’s a big need to prevent infections in hospitals and clinics. This makes SPT work stable and important for the healthcare system.
Final Thoughts
Even though Sterile Processing Technicians aren’t in the spotlight, their work is crucial. They make sure surgical tools are clean, safe, and ready to go. This keeps patients safe and helps doctors and nurses do their jobs better.
If you want a healthcare career that’s rewarding, important, and always in demand, becoming a Sterile Processing Technician might be the perfect choice for you!

from 178 reviewsI won’t lie, I failed the first time around. So I decided to buy this practice test and I passed with flying colors my second go. Highly recommend to anyone interested in the CER, it helped a lot!
The flash card quality is amazing! Bravo sir! The card quality is way above average, questions are great! I’m still learning, utilizing these cards and your practice tests. Thanks for all the info!
I passed the CRCST exam. Taking reg sterile guy practice test over and over definitely helped get the job done.
This certification prep course is a must. Great videos with a lot of information and plenty of of practice exams.
These flashcards are so helpful and well put together. Highly recommend!
I'm really happy that I purchased the SP practice exam. I love how if you answer the question incorrectly, the correct answer will include the page number of the text book to find the answer. The questions are literally based on the textbook. I suggested "The Sterile Processing Guy" to my friend that is studying for the exam as well.
Love.The digital product.Haven't got too far into it yet. I'm hoping that I'll be able to go back into and review it.
I ordered these flashcards and I’ve gone through them since I received it! This is exactly what I needed to help me pass my exam! Thank you so much! These flashcards are very good quality as well!!
I’m learning so many things while watching the videos and doing practice tests after each lesson! I was worried about not being able to grasp anything but the tests after each lesson really solidify the information I learned! Thank you so much for this way of teaching!
I purchased the course, the index cards and the extra quizzes. I don't have the book nor did I take any classes or go to any programs. My schedule was too busy, so I self studied with Brandon's incredible bundles. I HIGHLY recommend his course and the extra quizzes were chef's kiss.
PS: the combination of the course outline, the cheat sheets AND the videos is the key to really understanding the material. Thanks Brandon!
Very comprehensive and scholarly presented . Kudos Brandon!
The practice test really helped prepare for the certification test!
Hi these cards are of quality and value easy to learn and just amazing thanks
I just registered class about one week ago, and finished two modules. I have to say this 101 class make the process of preparing the CRCST exam much more easier. I mean each module is kind of short but full of necessary information for the exam and follow up with some practice questions with an answer page. I also have flash cards on the way, cannot wait to see it!!! I am planning to take my exam no later than August probably in the middle of August, hope I can pass it on my first attempt. 🙏
I took my test today for my provisional and I PASSSED! I bought the flash card bundle. I can say honestly your flash cards seem like a lot of hard work went into them. I’ll be honest i didn’t really use them as much but i found your practice test very helpful. I would take them every two weeks and it helped me a lot on my test. So thank you very much.
