Hi. I am an EMT-B currently and want to obtain a CNA certificate. I reside in Monmouth county NJ and will be a senior in HS, and 18 y/o this september. I was curious to know if I could even obtain a CNA certificate yet (I think you have to be 18). Regardless, how would I go about doing all this (getting the certificate)? How long will it take? How much will I be making? Could I work during the school year? and just for kicks, are there any other certificates I can get? Besides CNA? What about ER Tech? Just curious.
