Yes. The game is free to play with no sign-up. Signing in adds AI explanations for any term.
How does the CRCST vocabulary game work?
Each round shows a clue for one of 42 CRCST terms. Guess the term in six tries: green means the right letter in the right spot, yellow means the letter is in the term but in another spot, and gray means it is not in the term. After the round, read the explanation and play the next term.
Where do the CRCST terms come from?
OpenExamPrep researched each term from the HSPA content outline and primary sources, listed under Sources on this page. The game is independent study material, not an official exam resource.
What is the CRCST exam pass rate?
HSPA reports 10,083 passes and 5,286 failures in 2025, a 65.6% pass rate. That annual pass rate is separate from the unpublished numeric cut score.
How can I pass the CRCST exam on my first try?
Use HSPA's current content outline and reference list. Prioritize Cleaning/Decontamination, Preparation/Packaging, and Sterilization, which are 21% each, then review every remaining domain and missed practice item.
