The tutors in the Writing Center are professionals and are, therefore, subject to standard professional ethics.
Professional ethics govern their relationships with the students, other staff members, and faculty.
Encourage the student to deal confidently with the assignment rather than complain about it. Never allow yourself to say or indicate anything negative concerning a specific instructor's personality or methods. Listen only until you are able to direct the student's attention to the work at hand. Never allow yourself to disagree with a grade received by the student. Never estimate grades for a student, even by implication.
