About SterileTechExam
A free, independent study resource built for sterile processing professionals preparing for the CRCST exam.
Our Mission
Sterile processing technicians are on the front line of patient safety — every instrument they process, every sterilization cycle they run, and every tray they assemble directly impacts patient outcomes in the OR.
The CRCST certification validates the knowledge and skills that make sterile processing professionals effective. But quality exam prep has historically been expensive or scattered across textbooks, outdated resources, and inconsistent practice materials.
SterileTechExam was built to change that. Our goal is to give every CS technician — regardless of their financial situation — access to high-quality, evidence-based practice questions aligned with the HSPA Central Service Technical Manual and CRCST exam blueprint.
All 23 Chapters
Practice questions covering the complete CRCST curriculum from decontamination to sterile storage.
Detailed Explanations
Every question includes a full explanation, plain-English summary, and notes on why wrong answers are wrong.
Always Free
No paywalls, no subscriptions. Quality CRCST prep should be accessible to everyone.
