Overview
What Does a Certified Nursing Assistant (CNA) Do?
CNAs work directly with patients in nursing homes, hospitals, and assisted living centers, splitting time between personal care tasks and basic medical monitoring. Your day revolves around helping patients with daily activities they can't do alone.
- Turn or reposition patients who are confined to bed.
- Answer patient call signals, lights, bells, or intercom systems to determine what patients need.
- Feed patients or help them eat or drink.
- Measure and record how much food and liquid patients consume and how much urine and stool they produce, reporting changes to medical or nursing staff.
- Provide physical support to help patients perform daily activities, such as getting out of bed, bathing, dressing, using the toilet, standing, walking, or exercising.
- Document or report observations of patient behavior, complaints, or physical symptoms to nurses.
- Remind patients to take their medications or nutritional supplements.
- Review patients' dietary restrictions, food allergies, and preferences to ensure they receive appropriate meals.

Requirements
Licensing & Certification
You must pass state certification to work as a CNA — it's required by federal law for anyone working in Medicare or Medicaid facilities, which includes most nursing homes and many hospitals.
| Credential | Status | Cost | Renewal |
|---|---|---|---|
| CNA (State Certification) | Required | $60-$115 | Every 2 yr |
CNA (State Certification) (State Board of Nursing / State Department of Health) — Proves minimum competency to provide basic patient care in nursing facilities. Required in all states
- Exam: NNAAP (National Nurse Aide Assessment Program) or state-equivalent exam. Two parts: (1) Written/oral knowledge test with 70 multiple-choice questions covering Physical Care Skills (64%), Role of the Nurse Aide (26%), and Psychosocial Care Skills (10%); (2) Skills demonstration of 5 randomly selected clinical skills (handwashing always included) performed in 30 minutes before a state evaluator.
- Cost: $60-$115 depending on state (exam fees vary; e.g., California ~$105, Minnesota ~$64). Training program costs range $500-$1,850+.
- Renewal: Must have worked as a paid nurse aide for at least 8 hours during the renewal period. Most states require 12-48 hours of in-service continuing education (federal minimum: 12 hours annually). Must remain on the state Nurse Aide Registry in good standing.
Every state requires CNA certification, but training hours vary from the federal minimum of 75 hours to 180+ hours in some states. Most states use the standardized NNAAP exam through Credentia, though a few like New York and Illinois run their own tests. If you move states, you'll typically need to transfer your certification through paperwork and background checks rather than retaking the full exam.
No interstate compact exists for CNAs. You will need a separate license in each state where you practice.
Compensation
Certified Nursing Assistant (CNA) Salary
At $40k median salary, CNAs earn less than other health care roles but more than most jobs requiring similar training time. Compare this to pharmacy technicians ($39k) or medical assistants ($42k) — similar entry-level health care positions.
$40k/yr
median annual salary
You'll spend $2k-$4k and 3 months to start earning $40k — that means your training pays for itself in just 1-2 months of work. Few careers offer such a quick return on your educational investment.
Salaries vary by location and setting. Certified Nursing Assistant (CNA)s in metropolitan areas and specialty practices typically earn more than the national median.

HealthJob Analysis
Will AI Replace Certified Nursing Assistant (CNA)?
CNA work is fundamentally human and manual — AI cannot bathe patients, help them walk, or provide the physical assistance that defines this role. The core tasks of lifting, feeding, and personal care require human hands and judgment. Some facilities use AI for scheduling shifts or flagging patient changes in electronic records, but these back-office tools don't replace the bedside care CNAs provide.
Physical patient care (bathing, feeding, mobility) is irreducibly manual; AI only in back-office alerts and scheduling.
