I don't know if there is a college, but my old roommate learned from a guy that he became friends with. the guy was model through the agency that he was working at. He got some jobs, and he seemed to be doing fine, but what he told me is that he quit because he couldn't handle the rejections and how bad they made him feel about himself. But that is that business for you, some people can handle it and some people can't.
The modeling 'schools' aren't educational like real college. They teach an aspiring model how to apply makeup, how to hold themselves, how to pose, how to put blush on, etc etc etc. It costs many thousands of dollars, and there is NO guaranteeof a job. MODEL agencies are the place to go. You have to fit their idea of what they are looking for in a model. But, Tic_Tac and Mikelc's responses there pretty much nails the problems.
