What You Need to Work as a CNA, Aide or Medical Assistant
Entry-level healthcare work is open to many newcomers, yet every state and employer sets its own bar. Some roles want a certificate and a registry listing, others will train you on the job, and all of them check who you are before you touch a patient.
This independent guide lays out the usual requirements, then a three-step path: pick a training route, gather your documents, and prepare for the interview and first weeks.
- Requirements depend on your state and on the employer.
- Every healthcare employer checks identity, work authorization and background.
- Confirm that a course meets your state's rules before you pay.
Credentials by role
A certified nursing assistant completes a state-approved training program, passes a competency exam with a written part and a skills demonstration, and is then listed on the state nurse aide registry. Federal rules set a minimum for nursing home aides and states often ask for more, so check your own state’s health department. Home health aides who work for agencies paid through Medicare or Medicaid also need training and a competency check. Medical assistants are not licensed in most states, but employers often prefer a diploma or certificate from an accredited program and a national credential such as CMA, RMA or CCMA.
Checks employers run
Employers commonly screen for criminal history, sometimes with fingerprinting, and look up abuse registries and exclusion lists when the job involves vulnerable adults. Employers verify identity and work authorization through the Form I-9. Health facilities commonly ask for a tuberculosis screening, proof of vaccinations and a drug screen. An older conviction does not always close the door, though it can, so ask the employer or the state registry early to learn where you stand.
Physical and personal demands
Patient care is active work. Aides lift and turn people, stand for long stretches, help with bathing and toileting, and may work nights or holidays. Medical assistants move between rooms, draw blood, take vitals and handle records. Reliability, privacy habits under HIPAA and calm communication count as much as any skill.
- Safe lifting and transfer technique
- Respect for patient privacy and dignity
- Willingness to work a set schedule, including weekends
Work rights and other basics
You must be legally authorized to work in the United States. Most employers also expect a minimum age, a high school diploma or equivalent for some roles, a current basic life support card from a recognized provider and reliable transport. Language skills are a plus, particularly in home care. Check each ad for these basics before you invest in a course.

Before you open the next step, turn a pay figure from a job ad into monthly, weekly and hourly amounts.
Annual pay to monthly, weekly and hourly
Enter the gross annual pay shown in a job ad or offer, the months paid in a year and the weekly hours. If the ad shows an hourly rate, multiply it by the weekly hours and by 52 first. The result lets you compare different offers on the same basis.
Enter the annual pay, the months paid (12) and the weekly hours.
Arithmetic estimate only. Take-home pay depends on tax, deductions and your own situation: your payslip or the official tax calculator is what counts.
