In the final paper "Challenges of the professional deontology of educators" the very concept of deontology and professional deontology of educators is explained at first. As the concept of professional deontology of educators is poorly implemented, it is very important to clearly define it. Professional deontology is closely related to the ethical code, but in fact they are quite different. The code of ethics is only a small part of professional deontology. The code of ethics is clearly defined through principles and standards that educators are obliged to follow. Professional deontology is an extensive and insufficiently researched segment of the profession of educators. Researches in which educators participated and were questioned through surveys and questionnaires about their knowledge of professional deontology and violations thereof are cited and explained. It also talks about challenges and ethical dilemmas that educators face every day in their work and how to recognize them, how to deal with them and how to reduce them. Educators are asked if they recognize ethical dilemmas or unethical procedures in which situations this most often occurs. It is being considered whether additional education, expert meetings and workshops in the field of professional deontology of educators are necessary. The conclusion is reached as to what is needed to reduce ethical dilemmas if they exist. The current knowledge of preschool teachers in this area is analyzed and whether they themselves believe that additional education and constant advancement and investment in competence building are needed.
