This is an independent study tool and is not affiliated with, endorsed by, or sponsored by HSPA, AAMI or any certifying body.

WHAT'S INSIDE
- 518 practice questions, each explained and cited to its source
- 73 flashcards across all seven sections
- 8 study notes: the exam format plus one per section
- A timed 150 question, three hour mock
- Review of the questions you missed
- A readiness score for each section

A REALISTIC MOCK EXAM
The real CRCST exam has 150 multiple-choice questions in three hours: 125 are scored and 25 are unscored pretest questions. HSPA does not publish a fixed pass score, so the mock uses 105 of 150 (70%) as a study target and labels it as unofficial.

THE EXAM TOPICS
The seven outline sections (revised November 2023) and their weights:
- Departmental Considerations, 15%
- Cleaning, Decontamination and Disinfection, 21%
- Preparation and Packaging, 21%
- Sterilization Process, 21%
- Sterile Storage, Transport and Inventory Management, 9%
- Patient Care Equipment and Distribution, 5%

A few outline items are not covered, such as heat sealer settings; the app lists each gap.
