The Certified Registered Central Service Technician (CRCST) test from HSPA (Healthcare Sterile Processing Association) is part of the CRCST certification program designed to measure and recognize entry-level technicians to certify that they are capable of providing competent services as a central service/sterile processing technician.
The CRCST exam is one part of the overall certification process. In addition to passing the test, you must complete 400 hours of hands-on experience to be certified. That firsthand experience will play an important role in your test preparation. The CRCST test is taken on a computer at a testing center and costs $140 (as of March 2023).

CRCST Preparation Strategies
Passing the CRCST exam requires extensive hands-on experience, self-study, and/or taking IAHCSMM CRCST practice tests. After passing the test, you must also have either completed 400 hours of hands-on work or completed the 400-hours of service within 6 months of passing the exam to get your CRCST certification. However, if you have the experience but do not pass the CRCST test, you will not get your IAHCSMM CRCST certification. Therefore, it is vital that you push yourself to pass the test.
Considering the work experience that is required, paying attention while doing your work and not cutting corners is the most important preparation strategy. However, there are additional things you can do to supplement your knowledge and give yourself a better chance to pass the test.
Official Courses – Purdue University offers a full course that will prepare you for the test. The Purdue course will prepare you to take the test, and they also offer an externship placement service. Purdue University charges $420 for the course, plus fees, and $300 for the externship. Passing the Purdue course will prepare you for the exam, but it does not provide the certification.
Take Online Courses – There are a number of online courses, including one offered by iPrep, that can prepare you for the CRCST test. These courses include IAHCSMM CRCST practice tests that will prepare you for the test environment.
Self Study – The IAHCSMM’s education department has developed reference materials for study. The CS Technical Manual, 8th edition, ANSI/AAMI’s ST79, and AORN’s Guidelines for Perioperative Practice can be ordered through its website and will guide your study. The HSPA’s 9th edition of the CS Technical Manual will gradually become available starting February 2023.
Find your Strengths and Weaknesses
After taking a CRCST practice test, you should be able to identify which areas you need to focus your study time on. This will give you a better sense of what you actually know, as opposed to just feeling confident about certain sections.
Once you know which areas require additional focus, you need to create a study plan to strengthen areas where you need to improve.
Practice Answering Multiple-Choice Questions
While this might seem silly, there is a skill to excelling at multiple-choice questions. You have less than a minute and a half per question, making it important that you quickly read through the questions and answer choices and make a fast determination.
To be successful, you will need to learn how to eliminate options and make educated guesses. Find a guide that teaches these tricks and techniques.

Free CRCST practice test: Get to know what the IAHCSMM CRCST will be like by practicing with these sample questions:
Topic 1: Cleaning, Decontamination, and Disinfection
Sample Question 1 of 7
During the cleaning process of surgical instruments, a Central Service Technician notices some visible biofilm on a surgical scissor. What should the technician do next?
- Wipe the instrument with a dry cloth to remove the biofilm
- Proceed to the disinfection process as planned
- Immerse the instrument in an enzymatic cleaner to break down the biofilm
- Use a sterilization wrap to cover the instrument before processing
Correct Answer: C. Immerse the instrument in an enzymatic cleaner to break down the biofilm
Explanation:
Biofilm is resistant to regular cleaning, disinfection, and even sterilization processes. Thus, when biofilm is present, the instrument should be immersed in an enzymatic cleaner (C) to break down the biofilm. Wiping with a dry cloth (A) is not effective in removing biofilm. Proceeding to the disinfection process (B) or covering with a sterilization wrap (D) while biofilm is still present can lead to ineffective sterilization and potential cross-contamination.
Topic 2: Preparation & Packaging
Sample Question 2 of 7
While packaging a set of surgical instruments, a technician notices that a hinge instrument is not opening and closing smoothly. What is the best course of action?
- Lubricate the hinge and continue with packaging
- Replace the instrument immediately
- Send the instrument for repair and continue packaging without it
- Ignore the issue as it is not of major concern
Correct Answer: C. Send the instrument for repair and continue packaging without it
Explanation:
When a hinge instrument is not functioning correctly, the best course of action is to send the instrument for repair and continue packaging without it (C). Lubricating the hinge and continuing with packaging (A) would not address the underlying problem with the instrument. Replacing the instrument immediately (B) might not be an option if an exact replacement is not readily available. Ignoring the issue (D) could risk patient safety and procedural efficacy.
Topic 3: Documentation and Record Maintenance
Sample Question 3 of 7
A Central Service Technician discovers an inconsistency in sterilization records. What should the technician do first?
- Discard the records to avoid confusion
- Report the discrepancy to the supervisor immediately
- Correct the discrepancy on their own
- Ignore the discrepancy as it might be a minor error
Correct Answer: B. Report the discrepancy to the supervisor immediately
Explanation:
If a Central Service Technician discovers a discrepancy in sterilization records, they should report the discrepancy to the supervisor immediately (B). This is because any errors in sterilization records can have significant consequences for patient safety. Discarding the records (A) could eliminate important information. Correcting the discrepancy on their own (C) may not be appropriate without first discussing the issue with a supervisor. Ignoring the discrepancy (D) could also lead to adverse consequences if the issue is not resolved.
Topic 4: Sterilization Process
Sample Question 4 of 7
You’re a Central Service Technician and while processing surgical instruments, you find that the biological indicator (BI) for the steam sterilization process has turned positive. What should be your immediate course of action?
- Run the sterilization cycle again immediately with the same instruments
- Discard the biological indicator as it might be faulty
- Report the incident, quarantine the load, and reprocess all items
- Use a chemical indicator to confirm the result
Correct Answer: C. Report the incident, quarantine the load, and reprocess all items
Explanation:
A positive BI indicates that the sterilization process was unsuccessful. In this situation, the technician should report the incident, quarantine the load, and reprocess all items (C) to ensure patient safety. Simply running the sterilization cycle again (A) or using a chemical indicator to confirm the result (D) would not adequately address the potential for non-sterile instruments. Discarding the BI (B) ignores a serious process failure.
Topic 5: Customer Relations
Sample Question 5 of 7
In a situation where a department staff member has delivered contaminated instruments without adhering to proper protocol, what is the first step a Central Service Technician should take?
- Return the instruments to the department
- Directly inform the supervisor about the incident
- Sterilize the instruments before any further steps
- Communicate with the staff member about the protocol breach and its potential implications
Correct Answer: D. Communicate with the staff member about the protocol breach and its potential implications
Explanation:
While it may seem logical to take immediate action such as returning the instruments or sterilizing them, the first action should be to communicate directly with the staff member involved (D). This ensures that the person is made aware of the breach, understands the potential implications, and can take corrective action.
Topic 6: Sterile Storage and Inventory Management
Sample Question 6 of 7
What is the most critical factor to consider when choosing a location for sterile storage?
- The proximity to the sterilization department
- The accessibility for the end users
- The safety and sterility of the environment
- The availability of sufficient space
Correct Answer: C. The safety and sterility of the environment
Explanation:
While all these factors are important, the safety and sterility of the environment (C) is the most critical when considering a location for sterile storage. Sterile storage areas must provide a clean, dry, and well-ventilated environment that minimizes the risk of contamination.
Topic 7: Patient Care Equipment
Sample Question 7 of 7
A Central Service Technician is assigned to clean a recently used ventilator. Which of the following steps should the technician NOT take in this process?
- Wiping down the exterior of the ventilator with a hospital-approved disinfectant
- Submerging the entire ventilator in a disinfectant solution
- Detaching and disinfecting the tubing and masks separately
- Inspecting the ventilator for any damages or malfunctions
Correct Answer: B. Submerging the entire ventilator in a disinfectant solution
Explanation:
While all parts of the ventilator should be cleaned and disinfected, submerging the entire ventilator in a disinfectant solution (B) could damage its electrical and mechanical components. Hence, this step should not be taken. All other steps (A, C, D) are necessary in the cleaning and maintenance process.

Customer testimonial
I am currently studying to take my CRCST exam. I was told about this website through my program instructor. I find this website/ course very helpful. It allows you to take a practice exam which is very similar to the real one. It’s even timed. My favorite thing about this site is that when you’re taking a test, and you get an answer wrong, not only will you have access to the correct answer but they also give explanations as to why the answer is correct and why the others aren’t. This feature in itself has helped me a lot, especially when it comes to retaining the correct information.
