I was directed to a nursing continuing education link but it costs $42-$65 depending on how many "contact hours" to get certified, meaning take the test, pass it with a score of at least 70% and print out your certification. Does anyone know of a free online or on-campus (Seattle, WA) course? Hi Kasumi, if CNA means certified nursing assistant, the answer is no. I am required to get certified to be allowed to volunteer at a hospital pharmacy, if that helps.
