CNA Exam key facts & eligibility
| Conducting body | Your US state’s nurse-aide registry, under federal OBRA-87 standards; the competency exam is delivered by state-approved vendors (commonly the NNAAP by Credentia, or Prometric/Pearson VUE) |
|---|---|
| Official website | credentia.com ↗ |
| Mode | A nurse-aide competency evaluation in two parts: a written (or oral) knowledge test of multiple-choice questions, and a hands-on skills evaluation in which you perform several randomly selected clinical skills (hand hygiene is always included). The exact vendor and format vary by state. |
| Frequency | On demand, year-round, once you have completed an approved training program. |
| Scoring & marking | You must pass both the knowledge test (typically around 70 multiple-choice questions) and the skills evaluation; both must be passed to be certified. Failing the skills demonstration on any single required skill can fail that portion. |
| Score validity | Certification is maintained on the state registry with periodic renewal and work/continuing-education requirements set by each state. |
| Language | English (some states offer oral tests and other languages). |

Expert take: what CNA Exam really tests
The CNA competency evaluation, required under federal OBRA-87, has two parts — a written (or oral) knowledge test and a hands-on skills demonstration — and both must be passed to join the state Nurse Aide Registry. The skills portion is where many fail: each required skill (hand hygiene is always included) must be performed correctly and safely.
Preparation tips
- Rehearse the skills list from your state vendor’s handbook until every step is automatic.
- Never skip indirect-care steps (hand hygiene, privacy, safety) — examiners score them.
- Complete a state-approved training program first; it is a prerequisite to test.
Common mistakes to avoid
- Focusing on the written test and under-rehearsing the graded skills demonstration.
- Dropping a required safety or hand-hygiene step and failing an otherwise-correct skill.
