The Certified Registered Central Service Technician examination from the Healthcare Sterile Processing Association (HSPA) administers 150 multiple-choice questions in 3 hours across seven weighted domains — with Cleaning, Decontamination and Disinfection, Preparation and Packaging, and the Sterilization Process carrying 21% each. PassProfessor’s CRCST Exam Prep is being built for that examination: preparation organized domain by domain against HSPA’s current CRCST content outline, so your study follows the same structure the exam samples.
What is the CRCST credential?
CRCST — Certified Registered Central Service Technician — is HSPA’s introductory certification for sterile processing professionals. It recognizes technicians who have demonstrated the experience, knowledge, and skills to provide competent services in a sterile processing department: decontaminating, inspecting, assembling, packaging, and sterilizing reusable surgical instruments and devices, and storing and distributing them so they reach the point of care sterile, complete, and on time. HSPA is the association formerly known as IAHCSMM; the credential, the examination, and the content outline are HSPA’s. The CRCST is accredited by both the ANSI National Accreditation Board (ANAB) and the National Commission for Certifying Agencies (NCCA).
Certification takes two things, and candidates who plan around only one of them get surprised. The first is passing the examination. The second is 400 hours of hands-on experience in a sterile processing department, distributed as HSPA specifies: 120 hours in decontamination processes, 120 in preparing and packaging instruments, 120 in sterilization and disinfection, 24 in storage and distribution, and 16 in quality assurance processes. The hours can be completed before you test, or — under HSPA’s provisional certification — within six months after you pass: pass first and you hold provisional certification while you complete and submit the hours, and the certification is revoked if the hours are not completed and submitted within that six-month window. The examination also carries a testing window and a retake discipline — a mandatory six-week wait between attempts — that the companion guide sets out in full.
One clarification belongs on this page because the roster behind this catalog raises it: sterile processing has more than one certifying name in the wider field, but this program is the HSPA CRCST program — the only sterile-processing program in this catalog. Nothing here describes, borrows the facts of, or prepares you for any other body’s credential.
What is this program being built to cover?
The seven outline domains, at HSPA’s published weights. Three domains — Cleaning, Decontamination and Disinfection; Preparation and Packaging; and the Sterilization Process — carry 21% each, 63% of the examination between them. Departmental Considerations carries 15%, Sterile Storage, Transport and Inventory Management 9%, Professional Development and Human Relation Skills 8%, and Patient Care Equipment and Distribution 5%. The program in development is organized on that same map, so practice results can be read domain by domain and a thin domain shows while there is still time to repair it.
Process reasoning, not just definitions. Sterile processing is a chain — point-of-use treatment, transport, decontamination, inspection and assembly, packaging, sterilization, storage, distribution — and a failure at any link quietly undoes every link after it. The examination’s questions test whether you know where a described failure entered the chain and what the standard requires next. Preparation here is being built around that chain logic: parameters, indicators, and the standards the field works by — HSPA’s Sterile Processing Technical Manual (9th edition) is the examination’s named reference — rather than around isolated vocabulary.
The experience requirement, planned rather than discovered. The program’s companion guide walks the 400-hour structure and the provisional route in full, because when your hours land is a study-plan decision as much as an employment one.

This page states no price for the program, because no price for it stands decided on the record behind this page. It also states no question count for the program’s practice bank, because the bank is in development and this page makes no claim about a finished bank.
The real exam at a glance
| Fact of record | HSPA CRCST |
|---|---|
| Questions | 150 multiple-choice (125 scored plus 25 unscored pretest) |
| Time | 3 hours |
| Delivery | Computer-based at Prometric testing centers |
| Passing standard | Pass/fail — HSPA does not publish a passing percentage or score; overall score information is not released |
| Experience requirement | 400 hours of hands-on sterile processing experience (120 decontamination · 120 preparing and packaging · 120 sterilization and disinfection · 24 storage and distribution · 16 quality assurance), before testing or within 6 months after passing under provisional certification |
| Retake | Mandatory 6-week waiting period between attempts |
Read the passing-standard row as the complete fact: HSPA reports CRCST results as pass or fail and does not publish a passing percentage. The passing point is set through a criterion-referenced standard-setting procedure, and HSPA does not release overall score information. Any site that states a precise CRCST passing percentage as HSPA’s standard is stating something HSPA has not published. What you do receive is feedback by content area — which is why domain-organized preparation matters: it is the same map your result will be reported on if you need a second attempt.
How the seven domains divide the exam
| Domain (HSPA CRCST content outline) | Weight |
|---|---|
| Departmental Considerations | 15% |
| Cleaning, Decontamination and Disinfection | 21% |
| Preparation and Packaging | 21% |
| Sterilization Process | 21% |
| Sterile Storage, Transport and Inventory Management | 9% |
| Patient Care Equipment and Distribution | 5% |
| Professional Development and Human Relation Skills | 8% |
Cleaning, Decontamination and Disinfection (21%). Where the chain’s hardest judgments live: point-of-use treatment, manual and mechanical cleaning, and the distinctions between cleaning, low-level, intermediate-level, and high-level disinfection — including which process a given device and its Spaulding classification require.
Preparation and Packaging (21%). Inspection and assembly of instrument sets, selection of wraps, pouches, and rigid containers, chemical indicators and labeling, and the package integrity the sterilizer’s work depends on.
Sterilization Process (21%). Steam and low-temperature sterilization: parameters, cycle selection, load configuration, monitoring with physical, chemical, and biological indicators, and what a failed indicator requires you to do next.
Departmental Considerations (15%). The department as a system: layout and traffic flow, workflow direction from dirty to clean, documentation, and the regulatory and quality framework — the standards and agencies whose rules shape daily sterile processing work.
Sterile Storage, Transport and Inventory Management (9%). Protecting sterility after the cycle: storage conditions, event-related sterility, transport, stock rotation, and inventory practices.
Patient Care Equipment and Distribution (5%). The smallest domain: patient care equipment processing and the distribution systems that move sterile goods to the point of care, including case-cart logic.
Professional Development and Human Relation Skills (8%). Communication, teamwork, ethics, and the professional behaviors of the department — mixed through the sitting rather than isolated from the technical material.
How to use it
- Join the notify list today. The program is in development and enrollment is not open yet; the notify list is how you hear the moment it is. While you wait, read the CRCST exam guide — it walks all seven domains, the 400-hour requirement, and the pass/fail scoring question in depth.
- Plan your 400 hours alongside your study, not after it. Decide whether you will test with the hours complete or use the provisional route’s six-month window, and let that decision set your test date.
- Allocate hours by the outline. The three 21% domains earn the majority of your time because they are the majority of your score; Departmental Considerations at 15% is the next block.
- Study the chain, not the chapters. For every failure scenario, name the link where it entered — decon, prep, sterilization, storage — and the standard’s required response. That is the examination’s native question shape.
- Finish with timed, mixed practice, read by domain. Three hours, 150 questions. HSPA publishes no passing percentage, so there is no honest threshold to aim arithmetic at: test when every domain is consistently strong, with margin. Where this program uses 70 in practice scoring, 70 is a PRACTICE BENCHMARK ONLY: a study target we set, not HSPA’s standard.
Frequently asked questions
What does CRCST stand for, and who awards it? Certified Registered Central Service Technician, awarded by the Healthcare Sterile Processing Association (HSPA) — the association formerly known as IAHCSMM. It is HSPA’s introductory certification for sterile processing professionals, accredited by ANAB and the NCCA.
How many questions are on the CRCST exam, and how long is the sitting? 150 multiple-choice questions — 125 scored plus 25 unscored pretest questions — in 3 hours, computer-based at Prometric testing centers. HSPA gives weights as percentages of the scored examination, not as question counts per domain.
What score do I need to pass? HSPA does not publish one. Results are reported pass/fail; the passing point is criterion-referenced, and HSPA does not release overall score information. Treat any precise passing percentage attributed to HSPA with caution. In this program, 70 is a PRACTICE BENCHMARK ONLY — a study target, not HSPA’s standard.
What experience do I need besides the exam? 400 hours of hands-on experience in a sterile processing department: 120 hours each in decontamination, preparing and packaging, and sterilization and disinfection; 24 in storage and distribution; and 16 in quality assurance processes. The hours may be completed before testing, or within six months after passing under provisional certification — if they are not completed and submitted in that window, the certification is revoked.
What happens if I do not pass? You receive feedback by content area, and HSPA requires a six-week waiting period before another attempt. The feedback map matches the domain map this program is organized on, which is what a targeted second preparation cycle needs.
What are the seven domains and their weights? Departmental Considerations 15%; Cleaning, Decontamination and Disinfection 21%; Preparation and Packaging 21%; Sterilization Process 21%; Sterile Storage, Transport and Inventory Management 9%; Patient Care Equipment and Distribution 5%; and Professional Development and Human Relation Skills 8%, under HSPA’s current content outline.
What does the program cost? No price for this program stands decided on the record behind this page, so this page states none. The price will appear here when enrollment opens.
What does the real exam cost? This page states no examination fee. HSPA confirms its current fee when you apply; the companion exam guide discusses the fee HSPA publishes, labeled as HSPA’s.
How many practice questions will the program include? This page states no count, because the program and its bank are in development and are not presented as finished. The program’s stated ground is HSPA’s current CRCST content outline across all seven domains.
Is this program for any other sterile processing credential? No. This is the HSPA CRCST program — the sterile-processing program in this catalog. It does not describe or prepare for any other body’s credential, and no other sterile-processing program is offered alongside it here.
When will enrollment open? The program is in development as part of the expanding PassProfessor catalog. Join the notify list on this page and we will email you when enrollment opens. We are not publishing a date we cannot keep.
