What the CNA written exam tests

Every state’s nurse aide exam has a written (or oral) knowledge test and a hands-on skills test. The written test is multiple choice and asks what a nurse aide should do: give safe daily care, prevent infection, observe and report changes, protect residents’ rights and communicate well. The NNAAP content outline, used by Credentia states, weights it like this:

How to prepare for the skills exam

The skills exam is hands-on, so you prepare by practicing each skill on your state’s official checklist until you can do every step in order. Your state page links the official list. Graders watch for the same safety and courtesy steps on every task:

  • Knock, introduce yourself, identify the resident and explain what you are going to do.
  • Provide privacy with the curtain, screen or door before any personal care.
  • Perform hand hygiene before and after care; wear gloves when you may touch body fluids.
  • Lock the bed or wheelchair wheels before any transfer.
  • Finish with the bed in its lowest position and the call light within reach.

On the NNAAP, one of your five skills is always a measurement. Practice reading these until your numbers match a partner’s: manual blood pressure, radial pulse, respirations, urine output, weight. Critical steps are printed in bold on the official checklists; missing one fails the skill, even if everything else is right.

Common questions

How many questions are on the CNA written exam?

It depends on your state’s testing vendor. The Credentia NNAAP written exam has 70 multiple-choice questions in 2 hours (60 scored, 10 unscored). Headmaster states range from 60 questions (Massachusetts, New Mexico) to 80 (Oregon), and Indiana’s state exam has 100.

What score do I need to pass the CNA written test?

Credentia reports the NNAAP as pass or fail without a numeric score. States that publish a pass mark set it between 70% (Ohio, Oklahoma) and 80% (Missouri, Nevada, Indiana). The table above lists each state’s number.

Can I take the CNA test orally?

Yes, in most states. The NNAAP oral exam reads 60 questions aloud and adds 10 reading comprehension questions. Headmaster states offer an audio version, often for $5 to $10 more, and some read only the first part aloud to check English reading.

What is on the CNA skills exam?

You perform nurse aide skills in front of an evaluator. Credentia’s NNAAP picks five skills in 30 minutes, always including hand hygiene and one measurement. Headmaster picks three or four tasks in 30 to 40 minutes. Missing a critical (bold) step fails that skill.

How many times can I take the CNA exam?

Most states allow three attempts within one or two years of finishing training. Arizona, Wisconsin and Oregon allow unlimited attempts within their windows, and Washington allows four on the written exam.

Are these practice questions free?

The five-question sample on this page needs no account, and each topic drill has a free first attempt with a free account. The full timed exams and unlimited drills are part of the CNA practice pass.
