I think you can ask your employee to provide their license in order to make a copy or contact the nurse aide registry of your state. The nurse aide registry keeps track of those individuals who have met written and skills test criteria to be certified for employment in long-term care settings, usually nursing homes. The registry also maintains records of those nurse aides who have had a finding of abuse, neglect or misappropriation of property against them.
You can inquire on the status of a state tested nurse aide by accessing the registry through the Internet, you may call the nurse aide registry and use the voice automated system, talk to a nurse aide registry customer service technician, or use the web-based verification system. You can find contact information for all CNA registries here or by using the menu available on most pages of this website.
