Due to scientific and technological developments, rethinking approaches to teaching and learning, explosion of knowledge, paradigm shift from teacher centred approach to learner centred approach, increased diversity in students population, changed students’ personality, increased expectations of teachers and parents from students and increasing competitions among students has changed the role of teacher. The new role of teachers as ' professionals' can present us with some very unique ethical choices and ethical principles governing the teaching profession. Thus, there is a need to establish a set of guidelines, a code, that a teacher must adhere to for improving ethics of the teaching profession and it must serve model for the students also. Ethical teaching is concerned with the questions of value, i.e. making judgments about “good” or “bad” behaviour in any given situation. The standards, values, morals, principles, etc. make ethics that guide one’s decisions or actions. In this module, we are mostly concerned about code of conduct and code of professional ethics for teachers. We shall discuss the steps to be followed for developing code of conduct. In addition, draft for professional ethics given by NCTE is also discussed followed by four-tier mechanism in case of non-observance of code.
