Best CNA (NNAAP-style)Prep Courses & Study Guides (2026)
CNA certification has a mandatory piece you can't buy your way around — the state-approved training program (75–180 clock hours at a school or facility) — and an exam piece where prep products actually help. Most candidates who fail don't fail the written test; they fail the skills demonstration, which changes what's worth buying.
- Exam fee
- ~$90-160 depending on state/vendor
- Pass rate
- ~70-80% first attempt (written); skills portion fails more candidates

Our buying advice
Remember that no prep product replaces the state-required CNA training program (roughly 75-180 clock hours at an approved school or facility) — that's mandatory before you can even register for the exam, which itself runs about $90-160 through Credentia/NNAAP, Prometric, or Headmaster depending on your state. Candidates pass the written portion at roughly 75-80% on the first try but fail the hands-on skills evaluation far more often, so prioritize skills prep: 4YourCNA's free videos (matched to your state's test vendor) are the highest-value study hours available. For the written test, free question banks cover most of what paid products do — pay only if you've failed once or need structure, in which case a short CNA Plus premium window or a $19 Union Test Prep upgrade beats an open-ended monthly subscription. A $30 Credentia official practice exam makes sense only as a final dress rehearsal in NNAAP states.
