When you start researching sterile processing certification, you’ll run into two sets of letters: CRCST and CBSPD. They sound similar and people mix them up constantly — job postings, Facebook groups, even some schools use them interchangeably. Here’s the difference, how the two credentials actually compare on cost and requirements, and which one to pursue.
The quick version
- CRCST is a credential issued by HSPA (the Healthcare Sterile Processing Association). It stands for Certified Registered Central Service Technician.
- CBSPD is a certifying organization — the Certification Board for Sterile Processing and Distribution. The technician credential it offers is the CSPDT (Certified Sterile Processing and Distribution Technician).
So the honest comparison is really CRCST (HSPA) vs. CSPDT (CBSPD) — two entry-level sterile processing certifications from two different bodies. When someone says “I have my CBSPD,” they almost always mean the CSPDT.
Aseptic Technical Solutions is an independent training provider and is not affiliated with HSPA or CBSPD. Fees and requirements below are set by those organizations and can change — always confirm on their official sites.
Side-by-side comparison
| CRCST (HSPA) | CSPDT (CBSPD) | |
|---|---|---|
| Certifying body | HSPA | CBSPD |
| Exam fee | $140 | $135 |
| Exam format | 150 multiple-choice questions, 3 hours | 150 questions (125 scored + 25 pretest), 3 hours |
| Experience requirement | 400 hands-on hours (before applying, or within 6 months of passing) | Eligibility routes based on documented experience or training — see the bulletin |
| Renewal cycle | Annual — 12 CE points + $50 fee | Five-year cycle |
| Recognition | Most commonly requested in job postings | Recognized, and accepted by every state mandate — but named less often in postings |
What they have in common
Both certifications:
- Cover the same core work — decontamination, inspection, assembly, sterilization, sterile storage, and distribution. (New to the field? Start with What Is SPD?)
- Are legitimate, recognized entry points into a sterile processing career.
- Require passing a proctored knowledge exam plus documented hands-on experience.
- Require ongoing continuing education to stay current.
If you learn the material well, you’re prepared for the concepts either exam tests. The science of sterilization doesn’t change based on which body writes the questions.
How they differ in practice
Recognition
The CRCST is the more widely recognized and requested credential in most job postings. If you search sterile processing openings in most markets, you’ll see “CRCST required” or “CRCST preferred” far more often than CSPDT. That doesn’t make the CSPDT a bad credential — it means the CRCST is the safer default when you’re choosing your first one.
State law is not the tiebreaker here, despite what you may read elsewhere: every state that mandates certification accepts either credential. The case for the CRCST rests on employer demand, not on the statutes.
Renewal rhythm
This is a real difference in how the credential lives with you:
- The CRCST renews annually — 12 CE points and a $50 fee each year. Smaller, more frequent maintenance. Our CEU resources page can help you keep up.
- The CSPDT runs on a five-year certification cycle, with CBSPD publishing its own recertification requirements.
Neither is objectively better; annual renewal keeps you continuously engaged with new material, while a five-year cycle means fewer renewal transactions.
Eligibility and experience
HSPA’s path is very concrete: 400 hours of hands-on experience in a sterile processing department, paid or volunteer — and importantly, you can pass the exam first and complete the hours within six months, which is how most career-changers do it. ATS supports that step directly with hospital internship placement.
CBSPD publishes its own eligibility routes based on documented work experience or training; check the current candidate bulletin for the exact options before applying.
Curriculum alignment
ATS programs follow the HSPA 9th Edition and prepare you specifically for the CRCST — that’s true whether you choose self-study, live virtual, or in-person. A well-taught course covers the underlying science thoroughly, but our practice exams, question style, and pacing are built around the CRCST.
What about state certification laws?
Several states now require sterile processing technicians to be certified — including Pennsylvania, New Jersey, New York, Connecticut, Tennessee, and Delaware — and Minnesota from January 1, 2028. Importantly, all of these laws accept either the CRCST or the CSPDT, so neither credential locks you out of a mandate state. (Minnesota’s law is the broadest — it also accepts HSPA’s CER and CBSPD’s CFER endoscope credentials.)
If you live in a mandate state, read your state’s page and the law itself before choosing — the details matter. Our full breakdown is in Do You Need Certification to Work in Sterile Processing?
Which should you get?
For most people starting out, the CRCST is the safer first credential:
- It’s the one employers most often ask for by name.
- Its experience requirement has a clear, well-worn path — exam first, then 400 hours within six months — that works well for people entering from outside healthcare.
Choose the CSPDT instead if a specific employer or your state explicitly prefers it, or if you already meet a CBSPD eligibility route and your target hospital recognizes both equally.
Can you hold both? Yes — nothing stops you from earning both credentials, and some experienced techs do. But as a first credential, pick one, pass it, and get working. You can always add the second later once an employer is paying for your continuing education.

How to prepare (for either)
Whichever exam you target, preparation looks the same at its core: learn the science, then drill exam-style questions until nothing surprises you. A solid program walks you through infection control, decontamination, instrumentation, sterilization methods, sterile storage, and distribution — and then hands you practice exams that mirror the real test’s pacing. Two habits separate first-try passers from re-takers:
- Study on a schedule, not a mood. Whether that’s a 16-week cohort doing it for you or calendar blocks you set yourself in self-study, consistency beats cramming.
- Practice under time pressure. The CRCST gives you three hours for 150 questions — a bit over a minute per question. Take at least one full practice exam against the clock before test day.
And plan the hands-on side early. For the CRCST, the 400 hours are usually the slowest step of the whole journey — which is why internship placement is built into ATS programs. For a full timeline, see How Long Does It Take to Become a Sterile Processing Technician?

Frequently asked questions
Is CBSPD the same as CRCST? No. CRCST is a credential issued by HSPA; CBSPD is a different certifying organization whose technician credential is the CSPDT. Comparing “CRCST vs. CBSPD” really means comparing the CRCST and CSPDT certifications.
Which is better, CRCST or CSPDT? Both are legitimate, and every state mandate accepts either one — so this is not a legal question. The CRCST is more widely requested in job postings, which makes it the safer first credential for most people. The CSPDT makes sense if your employer explicitly prefers it or you already meet a CBSPD eligibility route.
Do employers accept CBSPD certification? Many do — the CSPDT is a recognized credential, and every state certification law accepts it alongside the CRCST. But since more postings name the CRCST specifically, check listings in your area before choosing.
How do the costs compare? HSPA lists the CRCST exam at $140; CBSPD lists the technician exam at $135. The two exams cost about the same — price is not a reason to pick one over the other. Renewal differs more: CRCST is annual (12 CE + $50), CSPDT runs on a five-year cycle.
Does ATS prepare students for both exams? ATS programs follow the HSPA 9th Edition and are built specifically for the CRCST. The underlying science overlaps heavily, but our practice exams and pacing target the CRCST.
