Prepare for the HSPA - Healthcare Sterile Processing Association Certification exam with our free practice test modules. Each quiz covers key topics to help you pass on your first try.
These are practice questions written for this site, not questions from the real exam. Each explanation shows why the right answer is right and why the others are wrong.
Question: What should be used to manually clean the channels of a flexible endoscope?
Answer: B. Channel-specific brushes sized to manufacturer specifications
Explanation:
The correct answer is channel-specific brushes sized to manufacturer specifications. A flexible endoscope has narrow channels of set diameter and length, and the brush has to contact the channel wall to dislodge soil and biofilm. A brush that is too small skips the wall, and one that is too large can scrape or damage the lining.
A lint-free cloth only cannot reach inside the channels. Hardware store pipe cleaners are not made for medical devices, can shed or snag, and are not validated for the scope. Compressed air without brushing may push soil further in or dry it in place, and it does not remove bioburden.
The rule to remember: for any device with lumens, follow the manufacturer's instructions for use and use the cleaning tools that instruction names.
Question: What is the primary reason that biofilm on a surgical instrument poses a significant risk to patient safety?
Answer: C. It protects microorganisms from cleaning agents, disinfectants, and sterilants.
Explanation:
The correct answer is that biofilm protects microorganisms from cleaning agents, disinfectants and sterilants. Biofilm is a community of microorganisms held in a slimy protective layer. That layer shields the cells beneath it, so a process that would normally kill them may fail, and an instrument can look clean and be treated as sterile while still carrying live organisms.
Discoloration and pitting is a surface condition, not the main patient safety risk. Interference with hinged instruments is a function problem, which matters but is not an infection risk. Added weight affecting handling is not a realistic concern. None of these explain why patients could be harmed.
The rule to remember: sterilization and disinfection only work on surfaces that have been cleaned first, so thorough cleaning comes before everything else.
Question: Where should an internal chemical indicator be placed within a sterilization pack?
Answer: B. In the area most challenging for sterilant to penetrate, typically the geometric center of the pack
Explanation:
The correct answer is the area most challenging for sterilant to penetrate, typically the geometric center of the pack. The internal chemical indicator is there to show that sterilizing conditions reached the hardest spot. If the indicator responds there, the easier locations were almost certainly reached as well.
On top of the instruments is easy to see but is the easiest place for sterilant to reach, so it proves little. Outside the wrapping is an external indicator's job, and it only shows that the pack went through a process. Saying position does not matter ignores the whole purpose of the indicator.
The rule to remember: place monitoring where conditions are hardest to achieve, because that is the strongest evidence for the whole load or pack.
Start with the official handbook on the HSPA site. Read the exam outline and note the content areas with the largest weight, since those are cleaning, preparation and packaging, and the sterilization process. Then check the recommended references the handbook lists, because exam questions are built from those standards and manufacturer instructions.
Next, take one practice set from each content area in the table above, without notes. Do not worry about the score at this stage. For every miss, write down the rule behind the right answer in a sentence of your own, and sort misses by area. That list tells you where to spend your time.
Spend the following study sessions on your weakest areas. Read the matching section of the reference material first, then retake the set a day or so later and see whether the same questions still catch you. Mix in the sets for microbiology, endoscope reprocessing and water quality if your work touches them, since they support several content areas.
Close to your test date, do a few mixed sessions to practise switching topics, and rehearse sitting through the 3 hours allowed. If you are still building your hands-on hours, ask your supervisor to walk you through each step you have only read about. Our questions are written by us for practice and are not real exam questions.
Quick review for the Healthcare Sterile Processing Association exam
This comprehensive HSPA study guide breaks down essential topics for the certification. Use these HSPA exam insights to focus your preparation on high-yield areas like sterilization methods and regulations.
The HSPA certification (formerly IAHCSMM) offers the Certified Registered Central Service Technician (CRCST) credential, which requires passing a 150-question exam covering decontamination, sterilization, and instrument identification. Candidates must also complete 400 hours of hands-on experience in a sterile processing department within six months of passing the written exam.
HSPA certification must be renewed annually with 12 continuing education (CE) credits submitted to HSPA. The exam fee is $140 for all candidates (including a $25 non-refundable application fee), and the test is administered through Prometric testing centers nationwide.
The HSPA sterile processing exam tests seven content domains, including cleaning, decontamination and disinfection (20%), preparation and packaging (20%), sterilization process (20%), and sterile storage and inventory management (10%), plus documentation, customer relations, and patient care equipment (10% each). Test-takers should know AAMI ST79 standards, biological indicators, and Bowie-Dick test protocols for prevacuum steam sterilizers.
Questions cover recognizing Kelly clamps, Metzenbaum scissors, Kerrison rongeurs, and retractors by name and function. Understanding instrument assembly, lubrication with instrument milk, and proper tray weight limits (25 pounds maximum per AAMI) is required.
An effective HSPA practice exam should mirror the 150-question format with a 3-hour time limit; since HSPA reports only pass/fail, treat 75% or better on practice tests as your target. Quality practice questions cover microbiology basics, Spaulding classification (critical, semi-critical, non-critical items), and ethylene oxide aeration times.
Pair practice tests with the HSPA Sterile Processing Technical Manual (9th edition, 2023), which is the official reference used to write exam questions. Focus review time on weak domains identified through practice test scoring reports rather than re-reading material already mastered. A short HSPA practice quiz of 20-25 questions per domain is enough to expose a weak area without burning a full 3-hour session.
The CRCST practice test HSPA candidates need most is one that behaves like the real thing. The live exam has 150 multiple-choice questions, but only 125 are scored; the other 25 are unscored pretest items mixed in at random, so treat every question as if it counts. With 3 hours on the clock, that is about 72 seconds per question, the pace to rehearse on any HSPA exam practice test before you sit at Prometric.
Weight your practice the way HSPA weights the exam. Cleaning and decontamination, preparation and packaging, and the sterilization process each carry roughly 20% of scored items, so about 75 of your 125 scored questions come from those three domains. The other four domains share the remaining 40%. If an HSPA practice exam shows you under 75% in any 20% domain, that is where your next study block belongs.
One thing a practice test cannot simulate: once HSPA approves your application you have a 120-day window to schedule at a Prometric center, so use your HSPA free practice test results to decide when to apply.
If you're preparing for multiple certifications in the sterile processing and healthcare technician space, you may also benefit from reviewing the AAC practice test to strengthen your grasp on related clinical terminology and procedures.
Candidates working toward advanced credentials often pair their HSPA study sessions with the AACC practice test to reinforce laboratory and instrument reprocessing concepts that overlap both exams.
The total HSPA certification cost typically ranges from $250 to $500 for self-study candidates, or up to $3,000 if attending a formal college program. Many employers reimburse these fees.
The HSPA CRCST exam is built from the official CRCST Exam Content Outline (revised November 2023 from HSPA's 2023 job task analysis), which splits the test into seven weighted sections. Use those weights to plan every HSPA CRCST practice test session: the three 21% sections together make up 63% of the exam.
Because the pass/fail cut score applies to your total result, a weak 21% section costs about four times as many questions as a weak 5% one. A practical routine for HSPA certification prep is one timed 150-question mock exam per week (three hours, as on test day), followed by short quizzes on whichever section scored lowest.
HSPA (the Healthcare Sterile Processing Association, formerly IAHCSMM) has certified sterile processing technicians since 1971. Besides the core CRCST technician credential covered on this page, HSPA certification includes three more exams, each $140 per attempt at a Prometric test center:
Once you hold CRCST, CIS and CHL can be taken in either order, and every HSPA credential is renewed annually through continuing education. Need a CER HSPA practice test? Free endoscope reprocessing questions are in our endoscope reprocessing practice test, built around the seven CER domains, from microbiology and infection control to human factors that impact endoscope systems. HSPA itself offers no practice exams beyond the quizzes in its study workbooks.
The CER exam is written from HSPA's CER Exam Content Outline (revised May 2022 after a 2021-2022 job task analysis). Like CRCST, it is a computer-based test of 150 multiple-choice questions with a three-hour limit and a $140 fee per attempt, but its seven domains carry very different weights:
Reprocessing steps alone are roughly one question in three, so when you take a CER HSPA practice test free on this site, put most of your review time there. HSPA names its Endoscope Reprocessing Manual (2nd ed.), ANSI/AAMI ST91 (2022) and the CDC's Essential Elements of a Reprocessing Program for Flexible Endoscopes (2017) among the references used to build the exam.
HSPA is the Healthcare Sterile Processing Association, the professional association that develops and awards the CRCST and other sterile processing credentials. It was founded in 1958 as the International Association of Healthcare Central Service Materiel Management (IAHCSMM) and is now based at 55 West Wacker Drive in Chicago. HSPA says nearly 60,000 members and certification holders rely on it for education, standards updates and certification.
HSPA certification began in 1971, when the association (then IAHCSMM) started formally certifying sterile processing technicians. Today it offers four exams: CRCST for technicians, CIS for instrument specialists, CER for endoscope reprocessors and CHL for leaders. The HSPA CRCST credential is accredited by both the ANSI National Accreditation Board (ANAB) and the National Commission for Certifying Agencies (NCCA).
Each of these four certification exams has 150 multiple-choice questions (125 scored, 25 unscored pretest items), a three-hour limit and a $140 fee, and is taken on computer at a Prometric test center. HSPA certification is renewed every year with 12 continuing education credits and a $50 fee, which covers all the certifications you hold.

Try these questions from our free Healthcare Sterile Processing Association Certification practice tests. The correct answer and an explanation follow each question.
A sterile processing technician is preparing to run a routine biological indicator (BI) test in a steam sterilizer. According to HSPA standards, what is the recommended frequency for this test?
Answer: C. At least weekly, but preferably every day the sterilizer is in use
Best practices and standards, such as those from AAMI, recommend that biological indicator monitoring of steam sterilizers be performed at least weekly, and preferably daily, for each sterilizer and for each cycle type used. [23, 28] Additionally, any load containing an implantable device must be monitored with a BI.
What is the purpose of a leak test performed on a flexible endoscope?
Answer: C. To detect damage to the outer sheath or internal channels that could allow fluid ingress
Leak testing detects perforations or damage in the endoscope's protective sheath and internal components. Fluid ingress through even a tiny breach can damage expensive internal optics and electronics. A failed leak test means the scope must be removed from service and sent for repair.
What is a Tosi test (Wash Check) used to verify?
Answer: B. Effectiveness of the washer-disinfector cleaning cycle
Tosi tests use standardized test soils run through the washer to verify cleaning effectiveness.
When should a leak test be performed during endoscope reprocessing?
Answer: B. Before manual cleaning but after bedside pre-cleaning
Leak testing must be performed after bedside pre-cleaning but before full immersion and manual cleaning. This sequence prevents further damage to a compromised scope during submersion. If the leak test fails, the scope should not be submerged and must be sent for repair.
