The school principal is the most important factor in school management, which has roles and responsibilities in increasing students' success in different educational processes. The school principal is the person who provides strategic guidance in the school system. School principals develop a standard curriculum, evaluate teaching methods, monitor student success, encourage parental involvement, review policies and procedures, manage the budget, appoint staff, and supervise the school for physical conditions. Security and emergency response are also the responsibility of school principals. An adequate school principal is a good teacher, a good manager, and a good civil servant. The overall development of a school largely depends on the school principal. This information points to the importance of both scientific studies on school principals and examining these scientific studies. It is also important to examine the keywords in scientific studies about school principals. Knowing which keywords are used in scientific studies about school principals, which is one of the most important study subjects in the field of educational administration, will contribute to understanding the aspects and dimensions of school principals in these scientific studies. The aim of this qualitative research is to determine the sub-dimensions, sub-topics and frequency of use of the keywords in scientific articles in which school principals participate or are the subject, and to group them thematically. The data of the research are limited to the articles published in the journals scanned in the TR Index (developed by TUBITAK ULAKBIM) between 2015-2019. In the research, document review method was used. The data were analyzed using the content analysis technique. In the research, 29 categories / themes and 336 keywords were determined as the main result. Some suggestions about the study were also made.
