The results demonstrated that each level of management is properly implemented. Furthermore, the term democratic education is not explicitly stated in the curriculum of boarding education; however, the spirit, values, ideas, perceptions, and practices of democracy manifested in daily life, such as the building of the spirit of cooperation in the student’s learning process, appreciation for fellow students and teachers, cleric and kyai, as well as the election of chairman regularly. The curriculum, which is considered to hidden, is firmly stated as numerous characteristics of the boarding school outside the studied ones, such as organizational aspects, social, and cultural systems, yet it is able to affect changes in students' values, perceptions, and actions.Keywords: Management; Democratic Education; Diversity Behavior
