Schools can be considered effective if there is well-organized management of facilities and infrastructure. This study aims to describe the management of elementary school facilities and infrastructure to create effective schools by using a mixed method. The utilized research design is sequential explanatory. This study employed saturation sampling with a population and sample of 41 people consisting of principals, educator representatives, and administrative staff. Quantitative and qualitative data were gathered through questionnaires, interviews, observations, and documentation. Quantitative data were analyzed by testing the validity and reliability of the instruments. In the meantime, qualitative data were analyzed by adopting the Miles and Huberman approach, which included data reduction, data display, and conclusion drawing. This study has been validated by two management experts who are professionals in their field from the Faculty of Teacher Training and Education at the University of Lampung. The reliability of the instruments was measured using Alpha Cronbach. The findings of this study reveal that the schools already have management of their educational facilities and infrastructure, however it is inadequate. The management of school facilities and infrastructure plays a significant role in the development of effective schools.
