Principal data education becomes the basis for temporary policy teacher appointments. Regarding the use of the main data system (DAPODIK) and its influence on local government policies in the education sector, the researchers had several important takeaways from this research, such as the use of the DAPODIK application system in schools in inputting educational data, which is still not optimal in its utilization. The research method used is qualitative with an inductive approach. There are a number of schools that use primary data education in the appointment of teachers, which is not permanent, but not effective. The main data on education is influenced by several factors; namely, teaching hours, subjects taught, and leadership policies. These factors are described in the research table of each district in West Sulawesi Province. The main data on education will affect school achievement because it requires the accuracy of the data on education, human resources, and policy evaluation.
