About this site
Last updated: July 19, 2026
SterilePassis an independent study site with one job: getting sterile processing technicians through the CRCST exam without wasting their money on subscriptions they'll forget to cancel.
How the questions are made
Every question is written originally against the publicly available HSPA exam content outline, then reviewed by a human before it ships, and checked so it does not resemble any recalled exam material. Explanations cite the underlying concept — the goal is that a wrong answer here teaches you the thing that would have cost you a point on exam day.
Who runs this
This site is built and run by an independent developer. More about the team soon.
