How Many Times Can I Fail the CNA Exam?
Updated September 4, 2026
Most states allow you to retake the CNA exam multiple times, but there is no single national rule. The number of attempts, waiting periods, and required training hours vary by state. Typically, you can take the exam three times within a two-year period, but you must reapply and pay fees each time. Some states, like Texas, permit unlimited retakes within the eligibility window, while others may limit you to three attempts before requiring a new training program.
State-Specific Rules and Waiting Periods
- Three attempts: Many states (e.g., Florida, California) allow three attempts within 24 months. If you fail all three, you must retake a state-approved CNA training course.
- Waiting periods: After a failed attempt, you typically must wait 30 to 90 days before retaking the exam. Check your state nurse aide registry for exact rules.
- Partial retakes: If you pass one section (written or skills) but fail the other, you only retake the failed portion in most states.
- Special cases: Some states allow more attempts if you show progress or have extenuating circumstances, but this is rare.
What Happens After You Exceed the Limit?
If you exceed your state's attempt limit, you must complete a new CNA training program before re-eligibility. This can cost time and money, so it's crucial to prepare thoroughly. Review your state's guidelines on the CMS Nurse Aide Registry page for official details.

Final Advice
Failing the CNA exam is not the end of your career. Many successful nurse aides passed on their second or third try. Use every attempt as a learning opportunity. For state-specific retake policies, always consult your state nurse aide registry.
