How hard is the CRCST exam?
The CRCST pass rate was 65.6% in 2025. What that number says about difficulty, what it leaves out, and which domains to study first. Free mini quiz included.

The pass rate is public, and it moved
HSPA's statistics table for CRCST, as of December 31, 2025, shows 10,083 passes and 5,286 fails. That is 15,369 exams and a 65.6 percent pass rate. The same table for 2019 shows 6,416 passes and 1,873 fails, 8,289 exams, 77.4 percent. More people are testing, and a smaller share are passing.
A lower pass rate does not tell you the cut score, and HSPA does not publish a raw percent-correct cutoff. It does tell you that walking in on work experience alone is a weaker bet than it was a few years ago.
What actually makes items hard
The hard items are usually decisions: which Spaulding class a device falls into, what a failed Bowie-Dick test means for the day's loads, when a biological indicator holds a load, and whose instructions win when habit and the IFU disagree. The IFU wins for that device.
Hands-on hours still matter. Full CRCST requires 400 hours, and a provisional pass gives you six months to finish them. The exam does not replace that time in decontamination, assembly, and sterilization.

What percentage do I need to pass?
