The quality of graduates serves as a central benchmark in evaluating educational outcomes at the secondary school level. In contemporary educational contexts, graduate quality encompasses not only academic attainment but also the moral integrity and spiritual values demonstrated by students in daily life. This study aims to investigate the implementation of combined curriculum management grounded in religious character education at SMP Negeri 18 Lebong, identify the strategies applied in embedding religious values within curriculum governance, and assess their influence on graduate quality. A qualitative case study design was employed, engaging the school principal, vice principal for curriculum affairs, classroom teachers, and students as research participants. Data were gathered through in depth interviews, structured observations, and document analysis, and subsequently analyzed using Miles and Huberman interactive model encompassing data reduction, data display, and conclusion drawing. Data credibility was ensured through source and method triangulation, member checking, and audit trail procedures. Findings reveal that combined curriculum management integrating religious character was enacted through the development of religiously informed curriculum plans, instructional practices that connect academic content with moral principles, and systematic habituation programs such as IMTAQ activities, congregational Dhuhr prayer, and Dhuha prayer. These initiatives contributed to measurable improvements in graduate quality across academic performance, character development, and social behavior. The study concludes that systematically embedding religious values into curriculum management constitutes a strategic framework for elevating educational outcomes and cultivating a character-oriented school culture.
