Registering as a certified nursing aide or assistant requires completing an application and submitting it to the appropriate state agency, according to Innerbody. For example, in Illinois, an application must be submitted to the Health Worker registry of the Illinois Department of Public Health, as indicated on the organization's website.
Each state has its own application process and requirements for an individual to qualify for registration as a CNA, Innerbody notes. Using Illinois as an example, the state requires registry applicants to successfully complete an approved CNA training program, pass a written competency test and have no disqualifying criminal convictions, the Illinois Department of Health explains.
The Illinois Department of Health states that various exceptions to the CNA training program requirement exist, such as already being registered as a CNA in another state, having obtained training in a nursing arts course such as an registered nurse or licensed practical nurse training program, or having been trained as a nursing aide in the U.S. military.
Each state has a nursing aide registry where information regarding registering as a CNA in that state is available, according to Innerbody. Some nursing aide training programs include certification, while others are broken into a basic nursing aide component and a certification component, notes Innerbody.
