What’s on the CRCST cheat sheet
- Cleaning, Decontamination & Disinfection (21%) — the Spaulding classification, cleaning-first rule, water quality, mechanical cleaning equipment, and the three levels of disinfection.
- Preparation & Packaging (21%) — inspection and lubrication, insulation testing, set assembly, chemical-indicator placement, and wrap, pouch, and rigid-container methods.
- Sterilization Process (21%) — steam and low-temperature parameters, the mechanical-chemical-biological monitoring trio, load release, failures, and recall.
- Departmental Considerations (15%) — one-way workflow, negative/positive pressure, SDS and chemical safety, the governing agencies, and quality assurance.
- Sterile Storage, Transport & Inventory (9%) — event-related sterility, FIFO, storage and transport standards, and traceability for recall.
- Professional Development (8%) & Patient Care Equipment (5%) — communication, HIPAA, teamwork, continuing education, plus preventive maintenance and distribution.
How to use it in your final week
- Front-load the three 21% sections — Cleaning/Decontamination, Preparation & Packaging, and the Sterilization Process together are about 63% of the exam, so if you master anything from the sheet, make it these.
- Drill the monitoring trio until it is reflex: mechanical (printout), chemical (color-change conditions met), and biological (resistant spores = the only proof of an actual kill).
- Memorize the Spaulding tiers cold — critical items get sterilized, semicritical need high-level disinfection, noncritical need low- or intermediate-level disinfection.
- Read the sheet the morning of your test for a last pass on the memory hooks — cleaning always precedes sterilization, event-related (not date-related) sterility, and one-way dirty-to-clean workflow that never runs backward.

CRCST cheat sheet FAQ
Yes — the CRCST cheat sheet downloads as a PDF at no cost and with no sign-up. It sits alongside Career Employer's free CRCST practice test, study guide, and flashcards, so your whole sterile processing prep is free in one place.
It condenses the highest-yield sterile processing facts into a fast reference: the Spaulding classification, cleaning-before-sterilization rule, steam and low-temperature parameters, the mechanical-chemical-biological monitoring trio, event-related sterility, and the seven HSPA content areas with their exact weights.
It is built from HSPA's November 2023 CRCST Exam Content Outline and the current CDC and AAMI ST79 standards the exam tests against. HSPA was formerly IAHCSMM, so older materials may use that name — it is the same certifying body.
No — the sheet is a cram and review layer, not a full course. The CRCST has 150 questions (125 scored) in 3 hours and is graded pass/fail, so use the sheet to lock in facts, then work full domain-weighted practice tests to find and fix weak sections.
