The present paper objects the light on the needs, principles, challenges and constraints in the implementation of Professional Ethics in teachers. Our values, attitudes and actions influence the impact of our work. These ethical principles constitute a common ground for the development of our ethical awareness. It is our responsibility to act in accordance with these values and principles. Speaking about the profession of teacher, it is necessary to consider contemporary global ethical issues in education and educational research. There is an opportunity for students to develop a critical stance towards some of the most pressing ethical issues in education and educational research in contemporary societies. In a school context and with the support of school polices, programs and practices, ethical education helps students to develop for example in depth knowledge and awareness of their own and other cultures. Like the legal eagles and medicos, lakhs of school teachers should also be bound by a stringent code of ethics in a bid to instill professionalism among them. Teaching creates all other professions.
