What you have going on here is a tutor with "inside information." I can certainly understand Jessica's discomfort, since at the extreme, her tutors working w/ their own classroom students could be functioning in a sort of dual "tutor job-faculty office hours" capacity. On the other hand, Maggi points out that tutoring is tutoring, ie. the goal really is to help students. I think I would personally allow my tutors to work with their own students, much as SI leaders do, but just not give over too much "inside" information, ie. lecture note supplement, interpretation of directions, assigned readings, etc. I would not want, for example, an absent-from-class student seeking out my tutor-instructor for what was missed in class. But, if the student is sincerely seeking help for writing strategies, this techer-tutor should help. Meet with your tutors and have your teaching-tutors discuss the ethics of this very interesting question before changing or setting policy. Good issue for discussion!
