If you’re looking into sterile processing, you’ll see four letters everywhere: CRCST. Here’s what it means, in plain English.
What CRCST stands for
CRCST stands for Certified Registered Central Service Technician. It’s the standard entry-level certification for sterile processing technicians, offered through HSPA (the Healthcare Sterile Processing Association) and built on the HSPA 9th Edition curriculum.
Aseptic Technical Solutions is an independent training provider and is not affiliated with HSPA.
In several states, holding a credential like the CRCST is now required by law to work in the field.
What the exam covers
The CRCST exam tests the core knowledge a technician needs on the job, including:
- Microbiology and infection prevention basics
- Decontamination and cleaning processes
- Inspection, assembly, and packaging of instrument sets
- Sterilization methods and quality controls
- Storage, distribution, and inventory
It’s a knowledge exam — your training program’s lessons, quizzes, and practice tests are designed to prepare you for exactly these areas.
What else is required
Beyond passing the exam, the credential involves a hands-on experience component — supervised hours in a real sterile processing environment. This is why training that connects you to a hospital internship is so valuable: it helps you meet the experience requirement and makes you more hireable.
How to prepare
Most people prepare through a structured program rather than going it alone. Good preparation includes:
- A curriculum that follows the HSPA 9th Edition
- Plenty of practice questions and quizzes
- A way to get hands-on experience
- Support when you get stuck
Our online self-study program covers the curriculum with AI voice-guided lessons, quizzes, and practice tests — and you can start today, from anywhere.
