Higher education is a professional system and the faculty should be aware of ethical standards of teaching considering their role in developing students and their obligation to them. Applying professional ethics in education ensures the right teaching-learning process in higher education institutions and can result in more commitment to students' needs.The aim of this review article, which is based on literature and related books and articles, is to examine the professional ethics of faculty as teachers and their role in the education and moral development of their students in view of ethical standards. In order to do this, samples of Islamic ethical issues related to the subject and some educational ethical rules of other countries have been investigated. Based on the professional ethics of teaching, teachers should pledge to ethical principles in two dimensions: firstly, they should behave decently considering their role in the students' moral development, and should be aware that the most effective method to characterize positive values in students is being actual role models. Secondly, because of the teachers' responsibility in meeting the educational needs of their students, they should have maximal commitment to ethical principles to perform professional tasks in the best way possible.
