Vocational education must prepare graduates who are technically competent, ethically grounded, adaptable, and ready to enter the workforce. This study analyzes how religious character and vocational orientation are integrated into student affairs management at SMK Al Islam Joresan, Ponorogo, Indonesia, and how this integration contributes to character formation and career readiness. Using a qualitative single-case study design, data were collected through semi-structured interviews, focus group discussions, observations, and document analysis involving school leaders, teachers, program coordinators, 15 students, 10 student council members, parents, alumni, and five industry partners. The data were analyzed thematically and iteratively. The findings show that integration occurs longitudinally through religious-value internalization, habituation, vocational learning and practice, student participation, career exploration, industrial internships, evaluation, and career transition support. Honesty, trustworthiness, discipline, responsibility, and integrity are translated into professional behavior through compliance with standard operating procedures and occupational health and safety requirements, as well as through communication, collaboration, independence, and accountability. The study proposes an integrative student development management framework that connects eight developmental components through a value–competence integration mechanism. The framework demonstrates the importance of aligning character formation, vocational competence, authentic work experience, school–family–industry collaboration, and transition evaluation to develop principled, competent, adaptable, and career-ready graduates.
