I have already taken a CNA course back in August 2006 and I worked in a doctor's office for two years and a half. I quit working in 2009. I have not used my CNA certification since then. I know that I have to take a retest but I was wondering could I take it online if not, do you know the name or number to where I can go to retest to activate my CNA again. I live in Fremont, North Carolina and I took my CNA course at Johnston Community College in Smithfield, North Carolina. Thank you for helping me.
