The CRCST exam, plainly.
The CRCST is the dominant sterile processing credential. The exam is part one; you must also document 400 hands-on hours within six months of passing.
If your school doesn't already point you at one specific certification, the CRCST is recognized across most U.S. employers in sterile processing.
The exam is administered by HSPA · Healthcare Sterile Processing Association. Full blueprint and registration are on the official site.
Cost, format, and scoring
The exam is computer-based and taken at a proctored testing center or via remote proctoring. You have 3 hr for 150 questions.
- Multiple choice, four options each.
- You may flag and revisit questions; no penalty for guessing.
- Pass/fail results are typically returned immediately on screen.
