Certified Nurse Assistant (CNA) training prepares you for an entry-level healthcare role through state-approved programs, combining classroom learning (anatomy, patient care basics, ethics) with hands-on clinical experience, typically lasting 4-12 weeks, and culminates in passing a state certification exam (like NNAAP) for licensure and placement on the nurse aide registry. These programs teach vital skills like assisting with daily living activities (ADLs), taking vital signs, and ensuring patient comfort, often with options for free training sponsored by nursing homes.
