There is always a need for CNAs and with a CNA license you will practically never be without a job. What are your goals? If you would like to be a RN as soon as possible, then you should look into an accelerated RN program. If you are looking to be a licensed nurse, then take the LPN or LVN program. If you want to get your foot in the door as soon as possible and eventually become a licensed or registered nurse, then take the CNA program. The CNA program can last either a few weeks or a few months depending on where you take it. LPN and RN programs are typically 18 month to 2 year programs.
