This study aims to analyze the implementation of the School of Ethics Program in shaping students’ character based on Islamic adab at SMP Mujahidin Surabaya. The research employs a qualitative approach using a case study design. Data were collected through in-depth interviews, non-participant observation, and documentation involving the principal, vice principal for curriculum, teachers, and students. Data analysis was conducted using an interactive analysis model consisting of data reduction, data display, and conclusion drawing, and was strengthened through triangulation of sources, techniques, and theories. The findings indicate that the implementation of School of Ethics is integrated into learning activities, habitual practices, and social interactions within the school environment. The internalization of Islamic adab values occurs through teachers’ role modeling, religious routines, and a school culture grounded in Islamic values. This program has a positive impact on changes in students’ behavior, both at school and within their family environment. The main supporting factors include a religious school environment and strong commitment from educators, while inhibiting factors stem from the influence of the home environment and rapid digital development. This study affirms that School of Ethics represents a contextual and applicable model of character education based on Islamic adab at the junior high school level.
