<![CDATA[The formation of students' religious character has become a crucial aspect of the national education system, particularly in the context of global challenges and adolescent moral crises. Al Firdaus Senior High School Sukoharjo, as a school based on national and international curricula (International Baccalaureate), develops Islamic Religious Education (IRE) curriculum integratively to strengthen students' religious values. This research aims to describe the planning, implementation, and impact of IRE curriculum on students' religious character formation. The study employs a qualitative descriptive approach with data collection techniques through interviews, observations, and documentation. Informants consist of the school principal, IRE teachers, and grade XI students. Research results show that curriculum planning is conducted through the development of learning modules based on learning achievements and contextual learning objectives. Learning implementation is carried out dialogically, reflectively, and based on student experiences. The impact of curriculum implementation is evident in the improvement of students' religiosity indicators, such as worship discipline, participation in religious activities, and strengthening of moral and social values. These findings affirm the importance of synergy between flexible planning, religious environment, and meaningful learning methods. The implications of this research indicate that schools need to continuously develop value-based curriculum and contextual learning to form individuals with good character and integrity in the global era.]]>
