Independent of HSPA

We are not affiliated with HSPA and never see real exam questions. Every question is written from HSPA's public content outline and the standards it names, so nothing here is a leaked or recalled item. How we write questions

  • Written to HSPA's current content outlineAll 7 domains, weighted the way the real exam weights them.
  • 300 exam-style questionsEach one explains the right answer and why every wrong answer is wrong.
  • Every explanation names its sourceMost cited: HSPA Sterile Processing Technical Manual (288), ANSI/AAMI ST79 (113), CDC Guideline for Disinfection and Sterilization (16), OSHA 29 CFR 1910.1030 (10), ANSI/AAMI ST58 (9). Number of questions in brackets.
  • An AI tutor for what you missAsk a follow-up question in plain words. Its answers are written by AI, so check them against the explanation.

Know which domain to study first

The free test scores every domain against the ready line, so you can see where the points are.

  • Weakest first. Domains are ranked by the points they would cost you on the real CRCST.
  • Practice what you miss. Short sets show the answer right away, and missed questions come back for review.
  • Book when you hit the line. Score 70% or more on full timed mocks.
