Looking for a free CNA practice test? Start with national written (NNAAP-style) practice, then confirm whether your state uses Credentia, Prometric, Headmaster/D&S, or another vendor — handbooks and skill lists differ.
National vs state
- National written practice — general nurse-aide knowledge aligned to common NNAAP domains
- State exams — registry rules, skills evaluated, and vendors vary; sample CA/TX scaffolds are illustrative only
How to practice
- Open the national CNA timed practice.
- Review vitals/infection control on the cheat sheet.
- Follow the study plan and study guide.
