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.
