How to Pass the CNA Exam: Written Test + Skills Guide

Becoming a Certified Nursing Assistant means passing two parts: a written knowledge test and a hands-on skills evaluation. Both are very passable with focused practice — here’s how.

The two parts of the CNA exam

You’ll take a written (or oral) knowledge test plus a skills evaluation where you perform several nursing-assistant skills for an evaluator. Topics span infection control, safety, communication, residents’ rights, and basic care.

How many questions and what score do you need?

The written test is typically 60–70 multiple-choice questions. Most states require about 70–75% to pass the written portion, plus successful completion of the required skills.

How to study for the written test

1. Practice questions on safety, infection control, and ADLs — the most-tested areas.
2. Learn residents’ rights and communication scenarios.
3. Review the rationale for every answer so the reasoning sticks.

How to pass the skills test

• Memorize each skill as an ordered checklist.
• Always start with handwashing and identifying the resident, and protect privacy throughout.
• Practice out loud until the steps are automatic — candidates usually fail on skipped safety steps, not knowledge.
