Sterile processing technicians are the quiet backbone of every hospital and surgery center. They clean, inspect, assemble, and sterilize the surgical instruments that operating rooms depend on. No sterile instruments, no surgery — which is why demand for trained, certified techs keeps growing.
If you’re considering the field, here’s the honest, step-by-step version of how to get in.
1. Understand what the job actually involves
A sterile processing technician (also called a central service or SPD tech) works in the decontamination and sterilization department of a healthcare facility. Day to day, that means:
- Decontaminating used surgical instruments
- Inspecting and assembling instrument trays
- Operating sterilizers (steam, hydrogen peroxide, and more)
- Tracking instruments and maintaining sterile storage
It’s hands-on, detail-driven, and genuinely important work — a great fit for people who like process, precision, and knowing their work matters.
2. Get the right certification
The industry-standard credential is the CRCST (Certified Registered Central Service Technician), built on the HSPA 9th Edition curriculum. Some states and employers also accept the CSPDT from CBSPD.
Aseptic Technical Solutions is an independent training provider and is not affiliated with HSPA.
In a growing number of states, certification isn’t just preferred — it’s required by law. (More on that below.)
3. Choose how you’ll train
There are three common paths, and the best one depends on your life:
- Online self-study — the most flexible and affordable option. You prepare for the CRCST on your own schedule, from anywhere. Ideal if there’s no school near you.
- Live virtual classes — the structure of a classroom with a live instructor, attended from home.
- In-person training — hands-on classroom practice, often with the strongest path to a hospital internship.
4. Get hands-on experience
Most certification paths expect supervised hands-on hours, and employers strongly prefer candidates who’ve worked in a real sterile processing workflow. This is where a program with hospital internship placement is worth its weight — it turns a certificate into an actual job.
5. Know your state’s rules
Several states now legally require sterile processing certification, including New Jersey, New York, Connecticut, Pennsylvania, Tennessee, and Delaware — with Minnesota’s law taking effect January 1, 2028. If you live somewhere with few local schools, online self-study is often the most realistic way to meet the requirement.

The bottom line
You don’t need a four-year degree or a school down the street to start a sterile processing career. You need solid CRCST preparation, some hands-on experience, and a plan. If you’re ready to begin, our online self-study program gets you started today — from anywhere.
