What distinguishes a competency record from a continuing education record?
- a.Competency is required yearly, and education records only at the time of hire
- b.Competency shows the person was observed performing the task correctly✓
- c.Competency records the contact hours earned at an outside conference
- d.Competency records belong to the technician, education to the facility
A competency record documents that a specific person was directly observed performing a specific task to a defined standard, such as operating the washer-disinfector or assembling a particular tray, and it is signed by the person who observed the performance. Contact hours earned at a conference belong on the continuing education record; attending a class shows exposure to information, not demonstrated skill. Both types of record are maintained by the employer in the personnel or education file, even though the technician also keeps copies for recertification. Competency is verified at hire, when a new process or piece of equipment is introduced, and on the schedule policy sets, while education accrues continuously rather than only at hire.AAMI ST79
Which quality test results belong in the department's permanent record set?
- a.Cleaning verification, biological and air removal results, plus load records✓
- b.The biological indicator results alone, since they are the definitive test
- c.Only the results that failed, because passing results need no follow-up
- d.Only the cycle printouts, because indicator strips fade and cannot be archived
The permanent record covers the whole process: cleaning verification testing of washers and ultrasonic units, daily air removal testing of dynamic-air-removal sterilizers, biological indicator results with their controls, chemical indicator and integrator results, and the load records that tie contents, cycle parameters and operator to each cycle. Keeping biological results alone leaves a recall unable to show that the load was properly cleaned or that air removal was verified. Keeping only failures destroys the baseline that makes a failure interpretable and hides trends. Cycle printouts are essential but incomplete on their own, and fading indicator strips are handled by policy on storage and by recording the result, not by discarding the record.AAMI ST79
A monthly audit finds operator initials missing from 30 percent of load records. What is the technician's part in correcting this?
- a.Go back through the month and add initials to the records left blank
- b.Ask the supervisor whether initialing the load records is still a requirement
- c.List the missing initials on a separate sheet filed with the monthly report
- d.Initial each load record at the time of processing, as the procedure requires✓
Operator identification on the load record is what makes a cycle traceable to a person, and the existing procedure already requires it, so the fix is for each technician to complete the entry at the time of processing rather than treating it as an open question. Asking whether the requirement still stands is a way of avoiding a duty that is already written down and documented in competency records. Going back and initialing records after the fact is retroactive documentation: the person cannot honestly attest to a cycle that may have been run days ago by someone else. Listing the gaps on a separate sheet measures the problem again without fixing it and leaves the original records incomplete.AAMI ST79
How do quality assurance and quality control differ in a sterile processing department?
- a.Assurance covers instruments, and control covers staffing and productivity
- b.Control builds and monitors the process; assurance checks the finished product
- c.Assurance builds and monitors the process; control checks the finished product✓
- d.Assurance is done in house, and control is done by an outside surveyor only
Quality assurance is proactive and process-oriented: written procedures, competency verification, preventive maintenance, monitoring and continuous improvement, all aimed at building a process that produces a reliable result. Quality control is the inspection side, checking the specific output against a specification, as when an integrator inside a tray or a cleaning verification test tells you whether that particular item met the requirement. Reversing the two inverts the definitions. Neither term is divided by subject matter, so splitting them between instruments and staffing is invented. And both are performed inside the department; an outside surveyor evaluates the program but does not constitute the quality control function.HSPA CRCST Content Outline
Why does a department track its immediate-use steam sterilization rate as a benchmark?
- a.A climbing rate points to thin instrument inventory or scheduling problems✓
- b.The rate determines the shelf life assigned to trays run in those cycles
- c.A climbing rate shows the department is meeting operating room turnover goals
- d.The rate sets how many biological indicators must be purchased each month
Immediate-use sterilization is meant for genuinely urgent situations, so the rate is watched as an indicator of underlying problems: too few instrument sets for the case schedule, sets held up in processing, dropped or contaminated instruments, or poor communication about add-on cases. A rising rate is a warning, not an achievement, because it means more items are released without full monitoring and without the protection of packaging, so reading it as evidence of good turnover misses the point. Indicator purchasing follows the monitoring policy for every cycle type, not the immediate-use rate. And items processed this way are transported immediately and used at once, so no shelf life is assigned to them at all.AAMI ST79
What does a tray audit measure?
- a.Whether the wrapper on a stored set is intact before the set is issued
- b.Whether assembled sets match the count sheet and hold functional instruments✓
- c.Whether the sterilizer reached the temperature and pressure shown on the printout
- d.Whether storage shelves are stocked to the periodic replenishment level
A tray audit is a scheduled inspection of assembled sets against their count sheets, checking that every listed instrument is present, that it is the right item, that it is clean and functional, and that indicators, protectors and labeling are correct. It measures the accuracy of the assembly process and feeds errors back to the technicians and to the count sheet itself. Verifying that the chamber reached temperature is physical monitoring of the sterilizer, read from the printout at the end of the cycle. Checking stock against the replenishment level is an inventory count. Inspecting a wrapper before issue is package integrity inspection, which every user performs, but it says nothing about what is inside the set.HSPA CRCST Content Outline
A department reports instrument set turnaround time. What is being measured?
- a.The number of sets one technician assembles during an eight hour shift
- b.Elapsed time of the sterilizer cycle from the start of exposure through drying
- c.Elapsed time from receipt of the soiled set to its release as a sterile set✓
- d.The time a case cart waits in the operating room before it is picked up
Turnaround time is the full elapsed time a set spends in the department, from the moment the soiled set is received through decontamination, assembly, sterilization and cooling, until it is released and available for the next case. It is tracked because it drives how much instrumentation the facility must own and how often immediate-use sterilization gets requested. The sterilizer cycle time is only one segment of that interval and is set by the cycle parameters. Sets assembled per technician per shift is a productivity measure. The wait before a soiled cart is picked up is a pickup interval, useful for point-of-use compliance but a different metric from turnaround.HSPA CRCST Content Outline
What does an inventory fill rate tell a department?
- a.The share of shelf space in sterile storage currently holding stock
- b.The share of case carts delivered to the operating room on schedule
- c.The share of requested items supplied from stock without a backorder✓
- d.The share of items on a case cart returned unused after the case ends
Fill rate measures service to the customer: of everything requested during a period, what proportion was supplied immediately from stock on hand rather than backordered, substituted or borrowed. A falling fill rate points to par levels that are set too low, unreliable ordering, or demand that has shifted. Shelf space occupancy describes how full the room looks and can be high while the right items are missing. On-time case cart delivery is a separate timeliness measure. Items returned unused indicate picking accuracy and preference card drift, which matters for cost and for reprocessing workload but is not a measure of whether requests could be filled.HSPA CRCST Content Outline
A department uses the Plan-Do-Check-Act cycle to reduce wet packs. What happens in the check step?
- a.The problem is defined, data are gathered and a corrective change is designed
- b.The trial change is run on one sterilizer for a defined trial period
- c.The change that worked is written into policy and spread department wide
- d.The results of the trial change are measured against the baseline data✓
The check step is the measurement step: the wet pack rate observed after the trial is compared against the baseline collected beforehand, which is what tells the team whether the change actually helped or whether the numbers simply moved. Running the trial on one sterilizer for a defined period is the do step. Writing a successful change into policy and spreading it across the department is the act step, and if the check showed no improvement the act step instead returns the team to planning. Defining the problem, gathering the initial data and designing the change is the plan step, which is what supplies the baseline that the check step later measures against.HSPA CRCST Content Outline
A department maps every step of tray assembly and removes the steps that add no value. Which method is this?
- a.Six Sigma, which targets variation and defects through statistical tools
- b.LEAN, which targets waste and non-value-added steps within a process✓
- c.Benchmarking, which compares department results against peer facilities
- d.Root cause analysis, which traces a single adverse event to its origin
Mapping a process and stripping out steps that add no value for the customer is the core of LEAN, whose targets are waste in the form of waiting, motion, transport, overprocessing and excess inventory. Six Sigma is a different discipline aimed at reducing variation and defects, and it leans on statistical measurement and a define, measure, analyze, improve and control structure. Root cause analysis is a retrospective investigation of one adverse event, asking why until the underlying system failure is exposed, rather than a redesign of a routine workflow. Benchmarking compares a department's measured results with peers or with internal history and identifies where to improve without describing how to redesign the work.HSPA CRCST Content Outline
How hard is the exam?
The HSPA CRCST (Certified Registered Central Service Technician) exam is 150 questions (125 scored plus 25 pretest) in 3 hours; results are reported pass/fail. The exam fee is $140. Medical equipment preparers earn a median of about $46,490/year (BLS, May 2024).
- Recommended study hours
- 60-100 hours for most, alongside the required hands-on sterile-processing experience hours.
- Pass rate
- We read HSPA's own published material in September 2026 and there is no pass rate in it. HSPA publishes counts, not a rate: for 2025 it reports 10,083 CRCST passes and 5,286 fails. We are not going to divide those for you and call the quotient HSPA’s pass rate — HSPA does not say whether the denominator is candidates or attempts, or whether repeat takers are counted twice.Source: HSPA — Certification Statistics (as of Dec. 31, 2025)
- Where to focus first
- Three areas tie as the largest at about 21% each — Cleaning/Decontamination/Disinfection, Preparation & Packaging, and the Sterilization Process.
Fees and salaries are approximate and change over time. The pass rate above is quoted from the source linked beside it, for the period that source covers — where we have not checked a source, we say so and give no number.
