Iterating, heavy editing, and rewriting should be taught before you get to college. Really they are the most important part of any sort of English composition. Getting words on paper is easy, getting the right words on paper is hard. As soon as you begin writing papers for school (in middle school, perhaps), you should be learning all of those skills. If you don't know them by college (which is entirely possible), they might be offered in a remedial 'English composition' course.
