Becoming a certified nursing assistant is one of the most practical decisions you can make if you want to enter healthcare quickly, earn a stable income, and build a real career with room to grow. The path is straightforward, the timeline is short, and the demand for qualified CNAs has never been stronger.
This guide walks you through every step of the process, from eligibility to exam to employment.
To become a certified nursing assistant, you need to complete a state-approved CNA training program (typically 75 to 150 hours), pass a two-part competency exam (written test and clinical skills evaluation), and register on your state’s nurse aide registry. The entire process typically takes 4 to 12 weeks.

Before enrolling in a CNA program, make sure you meet the basic requirements:
A high school diploma or GED is preferred by most employers but is not always a state-mandated requirement for training enrollment.
Not all CNA programs are equal. The program you choose must be approved by your state’s health department or department of education. NCOOA’s CNA exam prep online course is built around the federal CMS training standards that form the foundation for all state programs.

Federal law requires a minimum of 75 training hours for CNAs working in Medicare and Medicaid-certified facilities. Many states require between 100 and 150 hours. Your program will specify the total hours required based on your state.
Training covers topics including patient rights, infection control, communication, safety procedures, vital sign measurement, personal care, range of motion, and clinical documentation.
The CNA exam has two parts. Both must be passed to earn certification:
Written knowledge test:
A multiple-choice exam covering healthcare fundamentals, patient care, safety, and clinical concepts. Typically 60 to 70 questions with a 90-minute time limit.
Clinical skills evaluation:
A hands-on test where you demonstrate five randomly selected clinical skills in front of a trained examiner. Common skills tested include handwashing, taking blood pressure, assisting with ambulation, and providing perineal care.
For detailed preparation strategies, see our guide on how to study for the CNA exam.
CNA exams are administered by state-approved testing organizations, most commonly Prometric or Pearson VUE. After completing your training program, you will register for the exam through your state’s designated provider. Exam fees typically range from $90 to $150 depending on the state.
Once you pass both parts of the competency exam, your name is added to your state’s nurse aide registry. This registry is publicly searchable, and employers are required to verify your registry status before hiring you. Your registry listing confirms that you are a qualified, certified nursing assistant in good standing.
With your certification in hand and your registry listing active, you are ready to apply. CNAs are hired by:
Many facilities actively recruit new graduates and offer orientation programs for newly certified CNAs.
If you are exploring the broader landscape of caregiving careers, it is worth comparing your options. CNAs, home health aides, and personal care assistants each have distinct roles, training paths, and salary ranges. Understanding those differences helps you choose the right certification for your goals.
