Although general ethical principles such as moral values, principles of professional ethics, and principles of ethical conduct in Higher Education Institutions are principles determining the behavior and actions of the academic staff, there have been some ethics problems among students and academic staff. As the reasons of these problems are varied, the occurrence/ emergence of them can be completely different from each other. Failing to attend classes on time, presenting course load to be over-excessive, sending his/her assistant to classes instead, failing to perform objective evaluation, humiliating, insulting or sexual harassing students, failing to accurately assess students' performances, treating some students preferentially, and discrimination are stated among the conducts against professional ethics in the field of education. The primary responsibility of the academic staff is to ensure the well-being of students with his/her actions and decisions; to be honest; to be respectful to basic rights; to be credible; to behave in accordance with the law; to avoid using force; to continually improve him/herself; and to respect personal space.
