What is the difference between a PCT and CNA? I have been working as a Nursing Assistant for the past 4 years but have never been certified. There's a school here that offers PCT for $500. I was just wondering if I should just go for CNA at the local nursing home which is free. I'll have to sign a 1 year contract but I was thinking that even though I already have experience, the experience while being certified will help me secure a better job. Later on I plan on becoming an LPN and working with hospice care patients but for now I just want more experience in the field.
