It varies county by county. I live in Seminole County so I could tell you that procedure but otherwise I would recommend going to your county school board or visit their website and look up info on becoming a substitute teacher. It's pretty fun. I am actually considering a career as a full-time teacher. I would have to meet some further certification requirements but I just may be willing to do it if it means some sort of career in which I can possibly support my kids. I'm bout fed up with chasing this dream around.
