How to become a Certified Nursing Assistant (CNA)
CNA is the fastest legitimate entry point into US healthcare — most states require only a 75-150 hour state-approved training program followed by a competency exam. About 1.4 million CNAs and home health aides work nationally per BLS, primarily in long-term care, hospitals, and home health.
Training
Federal law (OBRA 1987) sets a minimum of 75 training hours; most states require 75-150 hours of state-approved curriculum split between classroom instruction (anatomy + physiology, infection control, patient rights, basic care skills) and supervised clinical practice. Programs are offered at community colleges, vocational schools, the American Red Cross, and many long-term care facilities directly (often free in exchange for an employment commitment).
Certification
After completing training, candidates sit for the state competency exam (written + hands-on skills demonstration). Passing both halves places the candidate on the state's Nurse Aide Registry — that registry listing is what employers verify before hiring. Some states use the Prometric or Pearson Vue NACES exam; others run their own.
Scope of practice
CNAs handle activities of daily living (ADLs): bathing, feeding, ambulation, repositioning, toileting, vital signs, basic measurements. They report observations to RNs/LPNs but do not administer medications or perform sterile procedures. Some states allow Medication Aide certification as an add-on credential that expands scope to limited medication passes under supervision.
Workplace
Skilled-nursing facilities (SNFs) and long-term care employ the majority of CNAs; hospitals (often as Patient Care Techs, a similar role with slightly broader scope) and home health agencies cover most of the rest. Workload is physically demanding and turnover is high, but the path provides direct patient-care experience often required for PA school + competitive nursing-school applications.
Career progression
CNA is widely used as the prerequisite patient-care experience for nursing school, PA school, and other clinical programs. Many CNAs progress to LPN (1-1.5 years additional training) or RN (2-4 years). PA-school programs typically require 1,000-3,000 hours of direct patient care; CNA work counts toward that requirement.
