Hi, I am about to start training as a CNA. I am self-employed in a different field, but wanted to get this certification primarily for volunteer purposes. I may work part-time for a while, but basically I just wanted to get certified in something so that I can have some credentials when I start volunteering. Someone told me that I wouldn't be able to keep my certification if I didn't work as a CNA. Is this true? I'm not sure if the rules are different for different areas. I'm in North Carolina. Any information would be appreciated. Thanks!
