How we write and review questions
What stands behind each CRCST question on CRCST Ready, where the facts come from, and what happens when something is wrong.
- Written to the published outline
Every question maps to one domain of HSPA's current CRCST content outline, and the bank is weighted the way the outline weights the exam. We have 300 questions across 7 domains.
- Every explanation names its source
Each answer explains why the right option is right and why each wrong option is wrong, then names the standard, regulation or manual it comes from. We cite sources by document and, where we can confirm it, chapter or section. We do not reproduce them.
- Checked by a credentialed expert
Andrew Hector Smith (CRCST, CIS, CHL) reviews questions and explanations against those sources and their own practice. Study guides show who reviewed them and when, or say that review is pending. About the reviewer
- Independent, so no leaked items
We are not affiliated with HSPA and have no access to real exam questions. We never use questions recalled from the real exam. Our questions test the same knowledge in our own words.
- Mistakes get fixed
Every question has a "Report a problem" button. Reports go to Andrew Hector Smith, and corrected questions are updated in the bank.
- The AI tutor is labeled as AI
The tutor answers follow-up questions using the question and its explanation. Its replies are generated by AI and can be wrong, so treat the written explanation and its source as the authority.
- Honest numbers
HSPA does not publish a passing score. We treat 70% on our mocks as ready. We don't publish pass rates or testimonials we can't back up.
