Before you buy
Is CRCST Practice made or endorsed by HSPA?
No. CRCST Practice is independent. It is not affiliated with, endorsed by, or sponsored by HSPA. Passing these quizzes does not grant CRCST certification.
Are the questions from the HSPA manual or workbook?
No. The 491 questions are original. They follow the public CRCST exam content outline (revised November 2023), and each one cites a public source such as the CDC disinfection and sterilization guideline, WHO, OSHA, FDA or EPA. They have not been expert-reviewed.
How close is a mock to the CRCST exam?
HSPA's exam has 150 multiple-choice questions and a 3-hour limit. The 2026 HSPA handbook says 125 are scored and 25 are unscored pretest items. A CRCST Practice mock is 150 scored questions weighted to the published domain percentages. It is not an HSPA exam form, and HSPA does not publish a percent-correct cut score.
What did the 2025 pass rate include?
HSPA's statistics page, as of December 31, 2025, lists 10,083 CRCST passes and 5,286 fails (15,369 exams). That is 65.6%. In 2019 the same table shows 6,416 passes out of 8,289 exams, which is 77.4%.
Where are the customer reviews?
CRCST Practice does not publish customer reviews. The pass-rate figures on this site are HSPA's published exam counts, not reviews of this product.
Do I need an account for the free quiz?
No. The 25-question quiz runs without signup and shows an explanation as soon as you answer. You only need an account to keep paid progress across devices.
What does the money-back guarantee cover?
Only the $39 plan (90 days). If you sit the CRCST exam during that window and do not pass, send your score report within 14 days and we refund the $39. It does not refund HSPA's $140 exam fee. A person reviews each request; nothing is refunded automatically.
