The issue is not teachers promoting their students' work. In some sense, they have a responsibility to do so. When people write dissertations with me, I am supposed to help them in their subsequent careers. A teacher should not help a student, however, by choosing his or her work in an open competition requiring an entrance fee. (If Jorie Graham were poetry editor of Iowa University Press and had absolute power to choose whomever she wanted for whatever reason, then the process would be above board.)
