CRCST Exam PrepThe short answer: HSPA's CRCST and CBSPD's CSPDT are both legitimate, widely recognized certifications for central service technicians. The biggest practical differences are scheduling and format: the CRCST is a 150-question multiple-choice exam ($140) you can schedule on demand year-round at Prometric, while CBSPD exams run in limited testing windows. Either credential satisfies state laws that require certification, so most candidates choose based on employer preference, scheduling urgency, and cost. You are also allowed to hold both.
Two bodies, one profession
Before comparing the exams, it helps to know who is behind each credential. The CRCST (Certified Registered Central Service Technician) is administered by HSPA, the Healthcare Sterile Processing Association (formerly IAHCSMM). HSPA is the larger and older of the two organizations, and its certification program is the one most sterile processing departments are built around. If you are new to the field, start with our overview of what the CRCST exam is to understand the full process from application to test day.
The competing credential is the CSPDT (Certified Sterile Processing and Distribution Technician), administered by the CBSPD, the Certification Board for Sterile Processing and Distribution. CBSPD is also a recognized, legitimate certifying body with its own exam, its own eligibility rules, and its own following among technicians and hospitals. Neither organization is a diploma mill and neither credential is fake. They are simply two different paths to the same goal: proving you can do the job safely.
Most candidates only ever earn one of the two. This guide will help you decide which one deserves your time and money.
Side-by-side comparison
| Feature | CRCST (HSPA) | CSPDT (CBSPD) |
|---|---|---|
| Credential name | Certified Registered Central Service Technician | Certified Sterile Processing and Distribution Technician |
| Certifying body | HSPA, the Healthcare Sterile Processing Association (formerly IAHCSMM) | CBSPD, the Certification Board for Sterile Processing and Distribution |
| Exam format | 150 multiple-choice questions in 3 hours; 125 scored plus 25 unscored pilot questions | Multiple-choice exam; check CBSPD's current exam bulletin for the question count and time limit |
| Scheduling | On demand, year-round. After your application is approved, you book a Prometric appointment and must test within 120 days of approval. | Limited testing windows. You register in advance and test during the next available window. |
| Exam fee | $140 | Fees vary by credential; $128 for the technician exam per CBSPD's current fee schedule. Confirm the current fee on CBSPD's website before applying. |
| Content organization | 7 weighted domains. Three domains at 21% each (cleaning and decontamination, preparation and packaging, sterilization process) make up 63% of the exam. | CBSPD's own published content outline; verify the current version on CBSPD's site. |
| State-law acceptance | Accepted in all six states that require certification by law | Accepted in all six states that require certification by law |
Exam format differences
The CRCST exam is fully documented and predictable in structure. You sit for 150 multiple-choice questions with 3 hours on the clock. Of those 150 questions, 125 count toward your score and 25 are unscored pilot questions being tested for future exams (you cannot tell which is which, so treat every question as if it counts). The content is organized into 7 weighted domains, and HSPA publishes exactly how much of the exam each domain represents. This is a serious exam but far from unbeatable with real preparation.
CBSPD's technician exam is also multiple-choice, but CBSPD publishes its format details in its own exam bulletin, and the specifics can change between testing cycles. If you are comparing the two, download both organizations' current candidate handbooks and compare them directly rather than relying on secondhand summaries.
Scheduling: the biggest practical difference
This is where the two paths diverge most. HSPA testing is on demand, year-round. You submit your application, wait for approval, then book your own appointment at a Prometric testing center at a date and time that suits you. The one constraint: you must test within 120 days of your application being approved. If a job offer or a state deadline is pushing you to certify fast, this flexibility is a genuine advantage.
CBSPD, by contrast, offers its exams in limited testing windows. You register ahead of time and test when the next window opens. That can mean waiting weeks or months depending on the calendar. For candidates who plan far ahead, this is a non-issue. For anyone in a hurry, it can be a dealbreaker. Before you commit to CBSPD, look up the upcoming testing windows and make sure the timing works with your plans.
Cost comparison
The CRCST exam fee is $140, paid when you apply. CBSPD's fees vary by credential, and the technician-level exam fee is $128 per CBSPD's current published fee schedule (confirm it on CBSPD's website before you budget around it). In practical terms, the two exams cost roughly the same once you account for possible fee changes, study materials, and travel to a testing center.
Remember that failing either exam means paying again to retake it, so the cheapest exam is the one you pass on the first attempt. Investing in solid preparation, including a free CRCST practice test to find your weak spots, usually costs far less than a retake.
Which one do employers prefer?
Here is the honest answer: most employers accept both. Job postings for sterile processing technicians commonly list the requirement as "CRCST or equivalent certification," and both HSPA and CBSPD credentials satisfy that language. Hospital HR departments are generally familiar with both organizations.
That said, the CRCST is the more widely held credential, and you will see it named explicitly in job postings more often. If you already know which hospitals you want to work for, search their current postings and see which certification they list. Local preference beats national averages. Also note that six states require sterile processing certification by law (Connecticut, Delaware, New Jersey, New York, Pennsylvania, and Tennessee), and either credential satisfies those laws.
If you are still deciding whether the field is right for you, read how to become a sterile processing technician for the full career path, including the 400-hour hands-on experience requirement that applies to CRCST candidates.
Which to choose if your state mandates certification
If you live in one of the six states where certification is required by law, either credential keeps you compliant. The deciding factors become practical ones: which exam can you schedule sooner, which content outline matches what you already know from the job, and which credential the hospitals near you name in their postings. A few more states, including Florida, Massachusetts, and Minnesota, are considering similar requirements, so earning a certification now is good insurance even if your state does not mandate it yet.
Can you hold both certifications?
Yes. There is no rule against holding both the CRCST and a CBSPD credential at the same time. Some technicians do exactly that to maximize their job mobility, particularly if they plan to work across states or for employers that name a specific certification. The tradeoff is cost and maintenance: you would pay two exam fees, meet two sets of eligibility requirements, and keep up with two sets of renewal requirements. For most people, one strong credential plus real experience is plenty.
How to decide: a simple checklist
Work through these questions in order and your answer will usually become obvious:
- What do local job postings require? Search openings at the hospitals where you want to work. If they name one credential, get that one.
- Does your state require certification? If yes, either credential works, so move to the next question. Our state-by-state guide lists all six mandate states.
- How soon do you need to test? If you need to certify quickly, HSPA's year-round on-demand scheduling at Prometric is the faster path.
- Which content outline fits your experience? Compare HSPA's 7 weighted domains with CBSPD's published outline and pick the one that maps better to what you already do every day.
- What is your budget? The fees are close ($140 for CRCST; $128 for CBSPD's technician exam), so cost should rarely be the deciding factor.
Whichever you choose, prepare the same way
Both exams test the same real-world knowledge: decontamination, instrument inspection and assembly, packaging, sterilization methods, storage and distribution, and the standards that keep patients safe. Learn the material deeply and you will be competitive on either exam. Start with the CRCST exam content outline to see exactly what the dominant exam covers, then test yourself with realistic practice questions before you pay any exam fee.
