About Us

Sterile Exam Prep is an independent study platform for people preparing for the Certified Registered Central Service Technician (CRCST) exam. We bring practice questions, explanations, and progress review together so each study session helps you decide what to work on next.

Why we are here

Preparing for a certification exam takes more than memorizing an answer key. It takes practice making decisions, understanding why an option is right or wrong, and returning to the topics that still need work.

Our goal is to give CRCST candidates a focused way to prepare. You can start with free questions, then use domain practice, answer review, and progress analysis to build a study routine around your own results.

We care about clear, useful learning because sterile processing work matters to patient care. Exam preparation should help candidates strengthen their understanding of the work, not just finish another quiz.

What guides us

Practice should teach

A useful question does more than reveal the correct answer. Our explanations help you understand the reasoning behind each option, so a missed question becomes something you can learn from.

Feedback should guide the next session

Practice across the seven CRCST knowledge domains, revisit missed questions, and use your progress by domain to decide what deserves attention next.

Pricing should be clear

Try 15 questions on the homepage before choosing a plan. Paid study plans use a one-time payment for a fixed access period, with no automatic renewal. See our pricing page for current plans.

Independent by design

Sterile Exam Prep is not affiliated with or endorsed by the Healthcare Sterile Processing Association (HSPA). Our practice questions are educational material, not official exam questions, and using this site does not guarantee a passing result.

For the official exam scope and certification requirements, refer to HSPA's CRCST information.
