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.

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
