This study delves into the "nadoman" tradition prevalent among the Sundanese people of Sumedang district, focusing on how religiosity is transmitted among elementary school children through "nadoman" as a medium for character education rooted in local wisdom. Sumedang district was chosen due to its declaration as the center of Sundanese culture under the "Sumedang as the Sundanese Cultural Center" government program. Utilizing an ethnographic design, the study involved 3 teachers and 30 elementary school students in the North Sumedang sub-district, Sumedang Regency-West Java. The study identified five significant themes: "nadoman" as an expression of appreciation for government policies, "nadoman" as an educational tradition for Sundanese Muslim children, "nadoman" as local wisdom, "nadoman" as a means for internalizing values, and the embodiment of students' religious character through the "nadoman" tradition. Ultimately, the study concludes that the "nadoman" tradition plays a vital role in fostering and fortifying the religious character of children involved, contributing to the development of a character education program rooted in local wisdom within formal education institutions.
