How to Become a CNA in Missouri: Step by Step

Follow these five steps to earn your CNA certification in Missouri. Most candidates complete the process in 4–6 weeks.

1
Meet eligibility requirements
You must be at least 16 years old (18 for some employers), have a high school diploma or GED, pass a criminal background check, and complete a health screening including TB test. Missouri uses the OBRA federal minimum standards as a baseline. Certain convictions are disqualifying — see our background check guide for details.
2
Complete 75 hours of state-approved training
Enroll in a state-approved CNA program — offered through community colleges, vocational schools, Red Cross chapters, and some nursing homes. Programs run 4–6 weeks and cover both classroom content and hands-on clinical hours. Hybrid programs (online classroom, in-person clinical) are available. Some long-term care facilities offer free training in exchange for a work commitment after you pass.
3
Pass the HDmaster competency exam
After training, register with HDmaster and pay the $105 exam fee. The exam has two parts: a written knowledge test and a clinical skills evaluation where you perform 5 randomly selected skills in front of an evaluator. Both parts must be passed — if you fail only one, you can typically retake just that section. Up to 3 attempts; new training required after 3 failures.
4
Get listed on the Missouri Nurse Aide Registry
Once you pass both portions, HDmaster reports your results to the state. Your name is added to the official Nurse Aide Registry, which employers verify before hiring. To keep your listing active, you must work at least 8 hours of paid nursing-related care during each 24-month renewal period. Your employer also provides 12 hours of annual in-service training.
5
Apply for your first CNA position
With your registry listing active, you can apply to nursing homes, assisted living facilities, hospitals, home health agencies, and adult day programs. Recent CNA grads are in high demand — most facilities post open positions year-round. Median pay for CNAs in Missouri is $15.88/hr.
