In this paper an emphasis is placed on the importance of knowing, applying and respecting the professional ethics of educators during their educational work. Education in early and pre-school educational institutions legally implies and appreciates the inclusion of children with developmental disabilities, and accordingly the educators need to be guided by the code of ethics as a guiding principle during the inclusive approach. The aim is to awaken the experts participating in the educational work in early and preschool educational institutions on the importance of ethical approach to working with children. Educators are key people involved in inclusive education of children in early and pre-school educational institutions. They face many challenges, doubts, and dilemmas every day, and do not know in what course they should direct their actions. They often unconsciously violate the basic ethical principles, mixing the professional values with their personal system of values. Educators are not sufficiently educated about their responsibilities which are set out in a multitude of documents. The lack of education is also reflected in making ethical decisions. Educators need enhanced investment in building and enhancing the system of values and competence. From an ethical point of view, an inclusive institution of early and pre-school education was observed, and access to inclusion by parents, educators and children was emphasized. Contemporary practice indicates the awakening of ethical awareness among all of the participants during the educational process, including the children.
