Favouritism is defined as the unlawful support and protection of people whom school administrators deem close to them. The aim of this research is to examine the favoritism behaviors of school administrators from the perspective of teachers, to reveal the possible effects of favoritism and to develop solutions. The study group of the research, which was conducted with the phenomenology method, one of the qualitative research methods, consists of 37 teachers who were determined by homogeneous sampling, one of the purposive sampling methods, in the 2021-2022 academic year. The data collected with a semi-structured interview form were analyzed by applying content and descriptive analysis techniques. Teachers explained the favouritism behaviors of school administrators with four themes (types, opportunities, problems and precautions). School administrators mostly favor cronyism and clientalism; the most common opportunity for people who benefit from favouritism is to give priority (leave, syllabus, shift, etc.) taking into account their wishes and needs; it has been determined that the most common problems caused by favoritism at school are grouping, restlessness, insecurity and reluctance, and the most possible measures to prevent favoritism in schools are assignment based on merit, creating a climate of justice and trust, and transparent and impartial supervision.
