What's on the CRCST exam
HSPA publishes how much of the exam comes from each area. Our timed exam deals its questions in the same shares, so it feels like the real one.
Instrument photo questions count toward Preparation and Packaging, where the real exam asks them.
The CRCST isn’t written from a single book.
“The SP Technical Manual, 9th Ed (2023), along with ANSI/AAMI’s ST79 (2017), and AORN’s Guidelines for Perioperative Practice (2025) were used for reference in creating the CRCST exam.”HSPA, 2026 Certification Handbook

Do the questions come with answers?
Every one. After each answer you see the right one and the reason for it, in practice and on today's five. On the timed exam you see them all when you hand it in, the way you would want to review a real one.
How is this different from a question bank?
A question bank hands you a list and lets you pick. This one picks for you: questions at your level, more from the areas you are weakest in, and your misses back when you are ready. You just press Practice.
How do I know when I'm ready?
Watch one number: your score, which counts each question by your first answer to it. When it stays over 70%, take the full exam. Pass that, and you have done it at full length on the real clock.
