It seems to me that your work qualifies for renewal but you should verify this by contacting the Illinois Health Care Worker Registry by e-mail at DPH.HCWR@Illinois.gov or by calling the registry’s help desk at 217-785-5133.
In Illinois, a CNA will lose their status of certification if he or she goes for a continuous period of 24 consecutive months after his or her last competency evaluation during none of which the individual provided nursing or nursing-related services for monetary compensation. If the CNA continuously works providing nursing-related services for money, the individual continues to retain the CNA certification no matter how many years the individual works.
