The CRCST is the credential that opens the door to a sterile processing career. Here’s what it is, who issues it, and why employers care — in plain English.
What CRCST means
CRCST stands for Certified Registered Central Service Technician. It’s the standard, entry-level certification for sterile processing technicians, issued by HSPA — the Healthcare Sterile Processing Association — and built on the HSPA 9th Edition curriculum.
In short: the CRCST is the credential that tells a hospital you know how to safely decontaminate, assemble, sterilize, and distribute surgical instruments.
Aseptic Technical Solutions is an independent training provider and is not affiliated with HSPA.
CRCST vs. the CRCST exam
People use “CRCST” to mean two related things:
- The credential — the certification you hold and list on your résumé.
- The exam — the knowledge test you pass to earn it.
This article is about the credential and what it’s worth. For a breakdown of the test itself, read What Is the CRCST Exam?
What it takes to earn the CRCST
Earning the credential has two parts:
- Pass the CRCST exam — a knowledge test covering microbiology, decontamination, instrument assembly, sterilization, and distribution.
- Complete the hands-on experience requirement — supervised hours in a real sterile processing environment (this is where a hospital internship matters).
You can pass the exam first and complete your experience hours afterward, which is why many people start studying right away.
Why the CRCST is worth it
- It’s often the minimum to get hired. Many hospitals won’t consider applicants without it — or expect you to earn it shortly after starting.
- In some states, it’s the law. A growing number of states now require certification to work in the field. See whether yours is one of them: Pennsylvania, New Jersey, Delaware, and Minnesota.
- It’s a real career on-ramp. The CRCST is the foundation you build on toward higher-level sterile processing and surgical roles.
How to get certified
Most people prepare with a structured program rather than self-teaching from a textbook. ATS preps you for the CRCST three ways — online self-study, live virtual, and in-person — all on the HSPA 9th Edition, with hospital internship assistance to cover the experience side.
