The distinction between an STNA (State Tested Nursing Assistant) and a CNA (Certified Nursing Assistant) primarily lies in the certification process and terminology used in different states. An STNA is a specific designation used in Ohio, where individuals must pass a state examination to become certified. In contrast, a CNA is a more general term used across the United States, referring to nursing assistants who have completed a training program and passed a certification exam, which may vary by state. In summary, while both STNAs and CNAs serve similar roles in providing care to patients, the key difference is rooted in the certification requirements and the terminology that varies by state. An STNA is recognized in Ohio and requires passing a state-specific test, whereas a CNA is a broader term applicable in various states, each with its own certification process.
