Most states require a CNA license to be renewed every two years. The expiration date should be on the license, but if it isn’t, the nursing assistant should contact the state nursing board.
In order for the license to be renewed, the nursing assistant should be working continuously as a certified nursing assistant for the minimum weekly hours as mandated by the nursing board. Additionally, the assistant must not have any complaints of neglect or abuse. If the individual has not worked continuously as a CNA, the license might become null and void. If this happens, then the individual would need to reapply and take the certification exam. In addition, the nursing board would run a background check.
Depending on the state requirement, a CNA might also have had to take continuing education courses during the two-year license period. If that state requirement isn’t met, the CNA might have to retake the certification exam.
