The principal, BK teacher, homeroom teacher, and students are the subjects of the study. This research method uses a qualitative research approach and collects data through observation, documentation, and interviews. Primary data sources are taken through direct observation results in the field, recordings of interview results that are first converted into word form and then we draw conclusions. Meanwhile, secondary data is taken through journals, books, and official school documents such as learning outcomes. The collected data is then analyzed through several stages which will later make it easier to draw conclusions. The results of the study theoretically show that organized student management with teacher supervision, communication between teachers and parents, and student involvement in school activities greatly contribute to student achievement and school quality. Practically, this study can be a guide for schools to improve student management, by increasing communication between teachers and parents, and designing programs to support student academic success and improve school quality.
