Check whether you qualify for full certification or need the provisional route, then plan around the seven CRCST content domains. Complete the required hands-on experience and use current reference materials to connect the exam topics with your supervised training.
What the CRCST credential covers
CRCST is HSPA's introductory certification for sterile processing technicians. You earn it by passing the exam and documenting 400 hours of hands-on departmental experience, then maintain it through annual recertification.
CRCST stands for Certified Registered Central Service Technician, issued by the Healthcare Sterile Processing Association (HSPA). It recognizes entry-level and experienced technicians who decontaminate, inspect, assemble, disassemble, package, and sterilize reusable surgical instruments and devices in a healthcare facility.
The program is accredited by both the ANSI National Accreditation Board (ANAB) and the National Commission for Certifying Agencies (NCCA). It is based on US practice and standards, aligned with international ISO standards, and open to candidates in the US and abroad who meet the eligibility requirements.
Certification requires two things: a passing exam score and 400 hours of hands-on experience in a sterile processing department. Certificants must then recertify annually through continuing education. The exam content below comes from HSPA's Certification Handbook, revised January 2026, and the CRCST Exam Content Outline, revised November 2023.

The 400-hour experience requirement and how to count your hours
Complete 400 hours in a sterile processing department, paid or volunteer, split into five required areas. Hours completed in the previous five years qualify under the recommended full route; otherwise you test as a provisional candidate and submit hours within six months of passing.
You must satisfy one of two options. Option 1, full certification, is the recommended path: document at least 400 hours of hands-on experience completed during the previous five years before you apply. Option 2, provisional certification, lets you test first and complete the 400 hours within six months of passing; you must submit documentation to HSPA before that deadline or your provisional status is forfeited and a paid retake exam is required.
So if you have already accumulated paid or volunteer hours, they count under the full route as long as they fall within the five-year lookback — and you can split them across more than one facility, with each facility documenting its own hours. HSPA does not provide placement services, so finding a department is your responsibility. If you want to use a dental, optical, or veterinary clinic instead of a hospital or surgery center, HSPA must review and approve the facility before you begin accruing hours there.
The hours break down into five areas, and your application must reflect that split. Documentation must come from your department's manager or supervisor — someone in a position above yours who has physically witnessed you performing the listed duties. Lead technicians, coordinators, supervisors, managers, directors, and hospital-based educators can sign; technicians and private instructors cannot, and you may never document your own experience.
One flexibility exists for provisional candidates: a one-time, two-month extension is available if you are currently working or volunteering in a sterile processing department and approaching the end of your six-month period. Your supervisor must request it before your provisional status expires, and extensions are not available if you have stopped working or volunteering in the field.
- Decontamination — 120 hours
- Preparing and Packaging Instruments — 120 hours
- Sterilization and Disinfection — 120 hours
- Storage and Distribution — 24 hours
- Quality Assurance Processes — 16 hours

Exam format, fees, and results
The exam is 150 multiple-choice questions in three hours, computer-based only, at a Prometric test center. The initial and retake fee is $140, and you have a 120-day window after approval to schedule.
The current exam contains 150 multiple-choice questions: 125 scored and 25 unscored pretest questions delivered randomly throughout the test. You cannot tell which are which, so answer every question. You have three hours, an optional 15-minute tutorial precedes the exam without counting against the clock, and you can flag questions for review and change them later. There is no paper-and-pencil version.
The initial exam costs $140, and each retake also costs $140. Fees cover application processing and one in-person attempt at a Prometric testing facility, with processing taking three to four weeks. Cancellation or refund requests must be made within 30 days of payment, and refunds are reduced by a $25 application fee.
Once your application is approved, you have 120 days to schedule and sit for the exam, which is offered throughout the year. After testing, you receive an on-screen pass/fail result that is also emailed within about 48 hours. Passing candidates receive a certification package by mail within roughly two weeks.
Your pass/fail status is determined by the number of scored questions you answer correctly. The handbook describes how minimum passing points are set: a standard-setting process in which content experts estimate the difficulty of each question, analyzed by psychometricians and approved by HSPA's Certification Council. These materials do not state a numeric passing score, so treat any specific cut score you see elsewhere as unverified. If you fail, your result report shows each knowledge domain as "At or Above", "Below", or "Well Below" — a general indicator, not a percentage score, and not part of the pass/fail decision.

The seven tested content domains
The exam weights three hands-on processing domains most heavily — cleaning and decontamination, preparation and packaging, and sterilization — at 21% each, with departmental considerations at 15% and the remaining domains lower.
The CRCST Exam Content Outline, revised November 2023 and built from the 2023 job task analysis, defines seven knowledge domains and their weights. Higher-weight domains represent a larger share of the exam; use that share and your practice results to allocate study time.
Each domain has sub-domains detailed in the official outline — for example, Section 7 covers communication, teamwork, and professional development, and its sub-domains include medical terminology, anatomy and physiology, and surgical terminology. If your study plan lists those as a separate subject, note that the outline places them under professional development rather than as a standalone domain. The official outline at myHSPA.org/certification gives the exhaustive sub-domain list.
| Domain | 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% |

How to prepare: three routes and the reference texts
A preparation course, self-study, or experience alone are all acceptable routes. HSPA requires none of them; the Certification Council does not develop, require, approve, or endorse any specific training materials.
Purdue University offers an online course to help you prepare, but a course is preparation for the exam only — passing one does not equal certification and is not required for eligibility. For self-study, HSPA names the references used to create the current exam: the SP Technical Manual, 9th edition (2023), and ANSI/AAMI ST79 (2017), plus AORN's Guidelines for Perioperative Practice. Note one discrepancy in HSPA's own materials: the certification page lists the 2023 AORN edition while the January 2026 handbook lists 2025, so verify the edition before you buy.
You may apply without purchasing a course. For self-study, map each outline topic to your reference material, test your recall, and review errors with a qualified supervisor or instructor. Keep terminology attached to the instruments and processes you are learning.
Application channels have changed over time. A past notice on HSPA's certification page set August 15, 2025 as the last day for paper applications unless paying by check or money order, with other applications submitted online; that notice is now historical. Follow HSPA's current application instructions to confirm which submission method applies to your payment and documentation.

Connect the outline to supervised practice
Use the outline as a checklist of what to review with your instructor or supervisor.
For topics such as package integrity, monitoring and implant-load quarantine, identify the current reference and facility procedure used in your training. Practice explaining what evidence is needed and where you would find the applicable instruction. The exam outline names these topics; it does not provide a complete release procedure.
- Track each topic as reviewed, practiced with supervision, or needing clarification.
- Ask for feedback on your explanation, then revisit the specific source behind any correction.

Practical cautions before you apply
Check who can document your hours and record your provisional deadline before you apply.
Do not document your own experience — the application sections must be completed by a qualifying manager or supervisor, and contact information must be current or your application will be rejected. Applications may be selected for verification, and if your supervisor cannot be contacted you have 120 days to provide the requested information before the application is cancelled and the fee is forfeited.
If you test provisionally, calendar the six-month submission deadline immediately and know the extension conditions. Marked-for-review questions can be revisited during the exam, and pretest questions cannot be identified — so use your full three hours and answer everything. Check your department's authorization status early if you are unsure it can sign off on hours, using HSPA's department authorization form.
