The CNA exam is separated into two sections: written examination AND clinical skills test. The written portion uses a multiple-choice format to test your knowledge of nursing concepts. You have 90 minutes to complete 60 questions. The clinical skills test requires you to perform nursing tasks in front of an evaluator. You must demonstrate approximately five duties in 30 minutes. Although perfection is not anticipated when performing these tasks, you are expected to self-correct when necessary, and be accurate when performing the critical steps of the tasks. A minimum of 70% per section is typically a passing score.

Keep in mind that each state has its own requirement regarding how much time you are allotted to complete both sections, and the percentage that constitutes a passing grade. The above guidelines are an approximation.

What do I need to do to become a CNA?

  1. Complete a CNA training program that is state nursing board-approved.
  2. Present your license application, program completion certificate, fingerprints, and processing fees.
  3. Pass both the written and clinical skills portions of the certification exam.
