CRCST Exam Prep, Sectioned So You Actually Finish
One site, split into the parts you actually revise: a practice test, a study guide ordered by the exam's real domain weights, and plain answers to what people ask before they sit CRCST.
CRCST is HSPA's entry-level certification for sterile-processing technicians, and everything here is built around one job: getting you ready to sit that exam. This is the study side — not a school, not a training program, not a shortcut to the credential itself. The work is broken into blocks you can take one at a time, so you are never staring down the whole exam at once.
Start wherever you are. Want to know how the questions feel? Take the practice test. Want to know what to study and in what order? Open the study guide — it is laid out by the real domain weights, heaviest first. Still deciding whether CRCST is even the right certification for you? The what-is page and the CBSPD comparison settle that before you spend a cent.

Compare
CRCST vs CBSPD
CRCST (HSPA) and CBSPD's CSPDT are rival certs from different bodies. An honest read so you pick the exam that fits your job.
Blueprint
The exam by domain
The CRCST exam is weighted, not even. Two domains — Cleaning, Decontamination and Disinfection and the Sterilization Process — together carry roughly two fifths of it, and the study guide follows that order so your first hours land where the most marks are. The five lighter domains still show up; they just do not deserve equal time.
- 21.1%Cleaning, Decontamination and Disinfection
- 20.8%Preparation and Packaging
- 20.8%Sterilization Process
- 15.0%Departmental Considerations
- 8.9%Sterile Storage, Transport and Inventory Management
- 8.0%Professional Development and Human Relation Skills
- 5.4%Patient Care Equipment and Distribution
