Actually... My badge says NA/R and I took classes (8 weeks) and had to take tests and had to take a certification test given by the state of Minnesota and am a registered CNA so Na/R's are official "CNA"'s... I talked to the charge nurse that im working with and she said that the titles vary by state. In ND theyre considered CNA's and in Minnesota theyre NA/R's... just my input though..
