<![CDATA[This article discusses the development of a hidden curriculum to strengthen the values of Islam Rahmatan Lil Alamin through the Islamic student association (Rohis) at SMKN 4 Malang. The discussion focuses on how organizational culture, role modeling, and daily habituation contribute to the internalization of Islamic values in a diverse vocational school environment. This study employs a qualitative case study approach, drawing on interviews, observations, and documentation involving the Rohis advisor, administrators, and active members. The data are analyzed through data condensation, data display, and conclusion drawing. The findings highlight three important aspects of hidden curriculum development. First, an inclusive and adaptive organizational culture encourages respect for differences among students. Second, the exemplary conduct of advisors and senior members serves as a living curriculum that promotes discipline, tolerance, politeness, and responsibility. Third, the habituation of religious practices helps integrate Islamic values into students’ social interactions and vocational learning environments. These aspects demonstrate that the Rohis extracurricular program can serve as a meaningful space for character development beyond formal religious instruction. The development of a hidden curriculum is therefore important in fostering students’ inclusive religious attitudes, harmonious social relationships, and ethical behavior in both academic and professional settings.]]>
