CRCST, CSPDT, CIS and CHL: Which Sterile Processing Certification Do You Need First?

Introduction

If you are new to sterile processing, the first certification to get is the CRCST or the CSPDT. The CIS and CHL come later, once you have experience. A recent CASRAI article compares all four, and this post explains the differences in plain terms.

Sterile processing is the hospital department that cleans, inspects, assembles, sterilizes and tracks surgical instruments so they are safe to use on the next patient. Certifications are how employers confirm you know how to do that work correctly.

What's Happening

CASRAI published a comparison of four sterile processing technician certifications: CRCST, CSPDT, CIS and CHL. We only have the headline and summary of that piece, so this post does not repeat its details. Instead, it explains what these four credentials generally are, based on what the issuing organizations describe.

• CRCST (Certified Registered Central Service Technician): issued by HSPA, the Healthcare Sterile Processing Association. This is the entry-level credential many hospitals ask for.
• CSPDT (Certified Sterile Processing and Distribution Technician): issued by CBSPD, a separate certifying board. It covers similar core knowledge and is also widely recognized for technicians.
• CIS (Certified Instrument Specialist): an HSPA credential aimed at people who focus on surgical instruments, such as inspecting, assembling and handling complex sets. It is usually a step after you have worked in the field.
• CHL (Certified in Healthcare Leadership): an HSPA credential for people moving into supervisor or manager roles.

In short, CRCST and CSPDT are the front door. CIS and CHL are for specialization and promotion.

Why This Matters for Sterile Processing Professionals

For a career changer, this comparison removes a lot of confusion. You do not need to pick among four exams on day one. You need to pick one of two entry-level exams, then decide later whether to specialize or lead.

Certification also ties directly to patient safety and compliance. Sterile processing follows the manufacturer's IFU (instructions for use, the written steps for cleaning and sterilizing each device) and facility policies. A certification shows you studied decontamination, sterilization methods, infection prevention and documentation. Many employers use it as a hiring filter, so it can decide whether your application gets read.

Be aware of the tradeoffs. The work is physical. You stand for most of a shift, wear gowns, gloves and face protection, and often work in warm, noisy rooms. Many departments run evening, night or weekend shifts, especially for entry-level roles. A certification will not change that, but it can open doors to better shifts and advancement over time.

What SPTs Should Know or Do

• Start with CRCST or CSPDT. Check job postings in your area to see which one local hospitals name most often.
• Check the current requirements on the official sites. HSPA and CBSPD each set their own eligibility rules, including education and hands-on experience, and those rules can change. Confirm them with HSPA or CBSPD before you plan.
• Treat CIS and CHL as later goals. Work in the department for a while, learn which part of the job you like, and then decide whether instruments or leadership appeals to you.
• Ask employers what they prefer. Some hospitals favor one credential, and asking early can save you a wasted exam fee.
• Plan your study time. The exams cover a wide range of material, from microbiology basics to tray assembly and sterilizer operation, so a structured course helps.

The Bottom Line

The four certifications in the CASRAI comparison are steps on one path, not four competing choices. The CRCST and CSPDT get you into the field, the CIS builds instrument expertise, and the CHL supports a move into leadership. If you are starting from retail, food service, caregiving or warehouse work, focus on one of the first two and worry about the rest after you have hands-on experience.
