The written exam and the skills evaluation
Becoming certified takes two assessments, not one. People preparing hard for the written examination and arriving unprepared for the skills evaluation is common enough that it is worth being explicit about which half this site is.
Two parts, both required
The candidate handbook is unambiguous: both parts of the examination must be passed. Passing one does not certify you, and the two are assessed in completely different ways.
The written examination is seventy multiple-choice questions on paper or screen. The skills evaluation is performed in front of an evaluator: you are given a set of skills to demonstrate on a person, and each one is marked satisfactory or unsatisfactory against a published checklist.
| Written examination | Skills evaluation | |
|---|---|---|
| Format | Multiple choice | Performed in front of an evaluator |
| What is assessed | Knowledge and judgment | Whether you can do the skill correctly |
| Scored how | Answers marked | Each skill satisfactory or unsatisfactory |
| Can a question bank prepare you? | Yes | No |

What this site is, and is not
This site is the written half. It has original questions on all nine content areas, weighted the way the blueprint publishes them, and it exists to make the knowledge and judgment part unsurprising.
It will not prepare you for the skills evaluation, and no written material can. That is practised with your hands, ideally with somebody watching, against the checklist your own state publishes — which is the document to work from, because it is the one your evaluator will be holding.
The overlap that is worth knowing
The two halves are not unrelated. The details that make a skill satisfactory — washing your hands before recording a measurement, putting the call signal within reach before leaving, explaining the procedure before starting it, providing privacy — are the same details the written questions turn on.
That is a useful way to revise: for any skill you are practising with your hands, ask what the written question about it would be. It is almost always about the step that protects the client, and that step is almost always the one people leave out when they are rushing.

Take a timed testFrequently asked
- Do I have to pass both parts of the CNA exam?
- Yes. The handbook states that both the written (or oral) examination and the skills evaluation must be passed.
- Can I practise the skills evaluation online?
- Not meaningfully. The skills evaluation assesses whether you can perform a task correctly on a person while somebody watches, and it is practised by doing it against your state’s published checklist.
- Is this site a nurse aide training programme?
- No. Certification requires a state-approved training course; this site is practice material for the written examination only.
