CRCST vs CSPDT: Which One Should You Get?

CRCST and CSPDT are both entry-level certifications for sterile processing technicians — the people who clean, inspect, and sterilize surgical instruments so hospitals can reuse them safely on the next patient. CRCST is issued by HSPA (formerly IAHCSMM) and CSPDT is issued by CBSPD. Most hospitals and surgery centers accept either one, so your decision usually comes down to eligibility, exam format, and renewal — not which name looks better on a resume.

Quick answer

	CRCST (HSPA)	CSPDT (CBSPD)
Issuing body	HSPA (Healthcare Sterile Processing Association)	CBSPD (Certification Board for Sterile Processing and Distribution)
Full name	Certified Registered Central Service Technician	Certified Sterile Processing and Distribution Technician
Education requirement	Completion of an approved training program or documented hands-on hours	Completion of an approved training program or documented hands-on hours
Exam format	Timed, multiple-choice exam covering decontamination, sterilization, and instrument identification	Timed, multiple-choice exam covering similar core content areas
Renewal cycle	Periodic renewal with continuing education credits	Periodic renewal with continuing education credits
Employer recognition	More commonly requested in job postings, especially in larger hospital systems	Accepted by many employers, sometimes preferred in facilities that already use CBSPD for other roles

Both certifications test the same core knowledge — Spaulding classification (how instruments are sorted by infection risk to decide the level of sterilization they need), decontamination steps, sterilizer operation, and instrument tray assembly. If you learn the material for one, you're prepared for the other.

What's the actual difference between the two organizations?

HSPA and CBSPD are two separate nonprofit organizations that each set their own standards, write their own exams, and manage their own renewal rules for sterile processing technicians. Neither one is a government agency, and neither certification is legally required by every state — but almost every hiring manager will ask for one or the other before they'll interview you.

HSPA has been around longer under its earlier name, IAHCSMM, and CRCST has historically been the more widely recognized credential nationally. CBSPD is smaller but well established, and CSPDT is accepted at hospitals and surgery centers across the country as well. Think of it less like choosing between two different careers and more like choosing between two testing companies that certify the same job skill.

Do the eligibility requirements differ?

Not in any way that should change your decision. Both HSPA and CBSPD require you to show you've learned the material — typically through a training program that covers the core sterile processing competencies, sometimes paired with documented hands-on experience. Neither one requires a college degree.

This is where your training program matters more than which exam you eventually sit for. A solid program prepares you for both bodies of knowledge at once, since the content overlap is heavy. That's part of why our 9-week course is built to prepare students for both the CRCST and CSPDT exams rather than picking a side — you finish able to sit for whichever one your local job market asks for.

Is the exam itself different?

Yes, in format and vendor, but not in difficulty or subject matter. Both exams are timed and multiple-choice, and both cover the same functional areas: decontamination (the process of removing blood, tissue, and debris from used instruments before they can be sterilized), high-level disinfection, sterilization methods like steam autoclaves and low-temperature systems, instrument identification, and following IFUs (instructions for use — the manufacturer's written steps for cleaning and sterilizing a specific device or tray).

Exact question counts, time limits, and passing scores are set by each organization and get updated periodically, so check HSPA's or CBSPD's current candidate handbook before you register rather than relying on secondhand numbers. What doesn't change is the underlying knowledge you need — if you know the material, the specific exam vendor is a formality.

How does renewal work for each one?

Both CRCST and CSPDT require periodic renewal, and both let you renew primarily through continuing education credits rather than retaking the full exam every time. The exact renewal window and credit requirements are set independently by HSPA and CBSPD, so once you're certified, you'll follow whichever organization issued your credential — you don't need to track both.

In practice, this means your certification isn't a one-time achievement. You'll need to keep earning a small number of continuing education hours each cycle, usually through webinars, in-services at your workplace, or conference sessions, to keep your credential active.

Which one do employers actually ask for?

Most job postings in this field say something like "CRCST or equivalent certification required," which means CSPDT satisfies the requirement too. CRCST tends to show up by name more often in job postings, partly because HSPA has historically had wider name recognition among hospital HR departments. That doesn't mean CSPDT holders get passed over — it usually means the posting was written using the more familiar term.

If you already know which hospital system or staffing agency you want to work for, it's worth checking a few of their current job listings to see which certification they name specifically. If you're not tied to one employer yet, either credential should open the same doors. For a broader look at how these certifications fit into the field overall, see our breakdown of sterile processing certifications.

Can I get both?

Yes, and some technicians do exactly that over the course of their career. Because the core content overlaps so heavily, once you've studied for one exam you're most of the way prepared for the other. Some people start with whichever certification their training program is built around, then add the second one later if a specific employer or promotion asks for it.

There's no real downside to holding both beyond the added exam fee and the ongoing renewal requirements for each. It's not necessary for most entry-level roles, but it can be useful if you plan to move between regions or health systems that lean toward different certifying bodies.

So which one should you choose?

Choose CRCST if you want the credential that shows up by name in the widest range of job postings, or if your training program is built around HSPA's standards. Choose CSPDT if a specific employer, staffing agency, or region you're targeting names CBSPD specifically, or if a CBSPD-aligned program is your most convenient training option.

For most people starting out, the honest answer is that it doesn't matter as much as it feels like it should. Both certifications lead to the same job title, the same starting pay range, and the same day-to-day work. The bigger factor in whether you get hired is whether you can demonstrate real knowledge of decontamination, sterilization, and instrument handling — not which two-letter acronym follows your name.

Ready to start?

If you're trying to decide between CRCST and CSPDT, the simplest path is a program that prepares you for both at once, so you're not locked into a choice before you've even started studying.
