The way I see it, you learn the basics in school, then fine tune them in a small market, and see how it really works. Nobody expects a baseball players to go from high school to the Baltimore Orioles. You have to start in single A to learn the nuances of the professional game. Ninety percent of my job has been learned in the field. Changing a battery in fifteen seconds before a live shot is not something you learn from a book.
Hard work does.
I don't think many stations really train their employees on gathering the news. I went last year and it really opened my eyes. This is why I believe that internships are priceless for the knowledge that they'll pick up in the course of 6 weeks or so at a station. At least they'll be exposed to this kind of quick thinking that isn't always available or taught at j-schools. Don't get me wrong.
