CNA Career Guide
Your complete roadmap to becoming a Certified Nursing Assistant and building a rewarding healthcare career.
What is a Certified Nursing Assistant?
A Certified Nursing Assistant (CNA) is a vital healthcare professional who provides essential, hands-on care to patients in hospitals, nursing homes, assisted living facilities, and home healthcare settings. CNAs work under the supervision of registered nurses (RNs) and licensed practical nurses (LPNs), serving as the primary point of contact for patients' daily care needs.
As a CNA, you'll make a meaningful difference in people's lives every day. You'll help patients maintain their dignity and independence while assisting with activities they can't perform on their own. The role combines compassionate caregiving with important clinical responsibilities, making it both personally rewarding and professionally valuable.
The CNA career path offers an excellent entry point into healthcare with relatively short training requirements, strong job security, and clear advancement opportunities to higher-level nursing positions.
