The document analysis method was used in the current study conducted to investigate the complaints against educational institutions and their stakeholders. To this end, the data obtained within the framework of the research questions were coded and categorized by using the descriptive analysis technique in the study, in which a total of two hundred documents and records of complaint made through various platforms were examined. When the findings obtained in the current study were examined, it was found that primary and middle schools are the types of schools that were subjected to the greatest number of complaints. At the same time, when the subjects of the complaints were examined, the subjects of hygiene-cleaning and physical conditions were found to be the most prominent subjects of complaints directed to the school itself and the subjects of physical, psychological and verbal violence against students, low grades given to students and indifference towards students were found to be the most prominent subjects of complaints directed to teachers. On the other hand, it was found that from among the subjects of complaints directed to the school administration, demands for donation, subscription fee and supplementary materials came to the fore and that from among the subjects of complaints directed to school principals, mobbing came to the fore. In addition to these, it was also found that the behaviours and attitudes of school service personnel, canteen food safety and high canteen prices, and violence and bullying among students are also the subjects of complaints.
