<![CDATA[This study aims to analyze the implementation of the da'wah management function in the spiritual development program at the Class I Medan LPKA, identify supporting and inhibiting factors in its implementation, and examine its contribution to strengthening the religious character of foster children. The method used in this study is a qualitative method with a case study design. Data were collected through interviews, observations, and documentation with the Head of the Development Section, religious instructors, and three foster children. Data analysis was conducted using the Miles, Huberman, and Saldana model through data condensation, data presentation, and drawing conclusions. The results of the study indicate that the spiritual development program has implemented the functions of planning, organizing, implementing, and monitoring, although the planning is not supported by documented material guidelines and supervision is not accompanied by systematic evaluation. The program is supported by cooperation with the Ministry of Religious Affairs, the commitment of religious instructors, and good interpersonal relationships between mentors and foster children, while obstacles include low initial motivation of foster children, psychological conditions, and a suboptimal program evaluation system. The spiritual development program contributes to shaping the religious character of foster children through habituation of worship, emotional control, and increased spiritual closeness.]]>
